RedTacton An innovative Human Area Networking technology that uses the surface of the human body as a transmission path

RedTacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. RedTacton uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separating ends the contact and thus ends communication. Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. RedTacton works through shoes and clothing as well.
RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver, where the weak electric fields affects the optical properties of an electro-optic crystal. The extent to which the optical properties are changed is detected by laser light which is then converted to an electrical signal by a detector circuit.
A communications path can be created with a simple touch, automatically initiating the flow of data between a body-centric electronic device and a computer that is embedded in the environment. For example, two people equipped with RedTacton devices could exchange data just by shaking hands. A wide range of natural human actions -- grasping, sitting down, walking, or standing in a particular place -- can be used to trigger RedTacton to start a networked process.
Using a RedTacton electro-optic sensor, two-way communication is supported between any two points on the body at a throughput of up to 10 Mbps. Communication is not just confined to the surface of the body, but can travel through the user's clothing to a RedTacton device in a pocket or through shoes to communicate with a RedTacton device embedded in the floor.
RedTacton can utilize a wide range of materials as a transmission medium, as long as the material is conductive and dielectric, which includes water and other liquids, various metals, certain plastics, glass, etc

CHAPTER-I INTRODUCTION
1.1 WHAT IS RED TACTON?
Human society is entering an era of ubiquitous computing, when networks are seamlessly interconnected and information is always accessible at our fingertips. RedWarmth, T-Touch, Acton-Action stands for Red Tacton. Instead of relying on electromagnetic waves or light waves to carry data, Red Tacton uses weak electric fields on the surface of the body as a transmission medium. Nippon Telegraph and Telephone Corporation (NTT) is pursuing research and development of an innovative Human Area Networking technology called Red Tacton that safely turns the surface of the human body into a data transmission path at speeds up to 10 Mbps between any two points on the body. Using a novel electro-optic sensor, NTT has already developed a small PCMCIA card-sized prototype Red Tacton transceiver. Red Tacton enables the first practical Human Area Network between body-centered electronic devices and PCs or other network devices embedded in the environment via a new generation of user interface based on totally natural human actions such as touching, holding, sitting, walking, or stepping on a particular spot. Red Tacton can be used for intuitive operation of computer-based systems in daily life, temporary one-to-one private networks based on personal handshaking, device personalization, security, and a host of other applications based on new behavior patterns enabled by Red Tacton. NTT is committed to moving Red Tacton out of the laboratory and into commercial production as quickly as possible by organizing joint field trials with partners outside the company
1.2 CONCEPTS ON RED TACTON
Red Tacton is a break-through technology that, for the first time, enables reliable highspeed HAN. In the past, Bluetooth, infrared communications (IrDA), radio frequency ID systems (RFID), and other technologies have been proposed to solve the "last meter" connectivity problem. However, they each have various fundamental technical limitations that constrain their usage, such as the precipitous fall-off in transmission speed in multi-user environments producing network congestion.

CHAPTER-II RED TACTON
2.1 BASIC PRINCIPLE
The basic principles of RED TACTON are 1. The Red Tacton transmitter induces a weak electric field on the surface of the body. 2. The Red Tacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter. 3. Red Tacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. 4. Red Tacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in an optical receiver circuit.
Fig.2.1. Figure shows the working of the RED TACTON device over the surface of our body. The transmitting RED TACTON device changes the electric field on the surface of our body. This is sensed by the electric field sensor and the variations are given to the receiving RED TACTON device.
2.2 MECHANISM OF RED TACTON
Data is received using a photonic electric field sensor that combines an electrooptic crystal and a laser light to detect fluctuations in the minute electric field. The naturally occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable. The photonic electric field sensor developed by NTT enables weak electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam.
Fig.2.2.Figure shows the various electric fields on the surface of our body induced by the RED TACTON device. Only a portion of the induced electric field is sensed by the receiving RED TACTON device. The remaining electric fields are dissipated to the ground.
2.3 RED TACTON TRANSCEIVER
Figure below shows the block diagram of a RED TACTON transceiver. The signal from the interface is sent to the data sense circuit and the transmitter circuit. The data sense circuit senses the signal and if the data is present it sends control signal to the transmitter which activates the transmitter circuit. The transmitter circuit varies the electric field on the surface of our body. This change in the electric field is detected by the electro-optic sensor. The output of the electro-optic sensor is given to the detector circuit, which in turn given to the interface of the receiving RED TACTON device.

2.4 FUNCTIONAL FEATURES
1. A communications path can be created with a simple touch, automatically initiating the flow of data between a body-centric electronic device and a computer that is embedded in the environment. For example, two people equipped with Red Tacton devices could exchange data just by shaking hands. A wide range of natural human actions grasping, sitting down, walking, or standing in a particular place can be used to trigger Red Tacton to start a networked process.
2. Using a Red Tacton electro-optic sensor, two-way communication is supported between any two points on the body at a throughput of up to 10 Mbps. Communication is not just confined to the surface of the body, but can travel through the user's clothing to a Red Tacton device in a pocket or through shoes to communicate with a Red Tacton device embedded in the floor. Unlike wireless technologies, the transmission speed does not deteriorate even in the presence of large crowds of people all communicating at the same time in meeting rooms, auditoriums or stores. Because the body surface is the transmission path, increasing the number of connected users directly increases the available number of individual channels.
3. Red Tacton can utilize a wide range of materials as a transmission medium, as long as the material is conductive and dielectric, which includes water and other liquids, various metals, certain plastics, glass, etc. Using ordinary structures such as tables and walls that are familiar and readily available, one could easily construct a seamless communication environment at very low cost using Red Tacton. (Note that constraints are imposed by the length and environment of the propagating conductor, and by the thickness of the dielectric.)
CHAPTER-III PROPERTIES
3.1 FEATURES
RedTacton has three main functional features. 3.1.1 Touch Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping or connecting and disconnecting the equipment, or obtaining data.
Fig.3.1.Figure illustrating that RED TACTON device can be triggered by touching and gripping.
3.1.2 Broadband & Interactive Bandwidth does not deteriorate even with duplex operations and simultaneous access by many users! Duplex, interactive communication is possible at a maximum speed of 10Mbps. Because the transmission path is on the surface of the body, transmission speed does not deteriorate in congested areas where many people are communicating at the same time. 3.1.3 Any Media In addition to the human body, various conductors and dielectrics can be used as transmission media. Conductors and dielectrics may also be used in combination.
Fig.3.2.Any type of medium (metal, water, etc) can allow flow of signal.
3.2 APPLICATIONS
3.2.1 One to one services With the ability to send attribute data from personal information devices worn on the body to computers embedded in the environment, one-to-one services could be implemented that are tailored to the individual needs of the user.
3.2.2 Intuitive operation of personal information Communication is triggered by totally natural human actions and behavior, so there is no need to insert smart cards, connect cables, tune frequencies, or any of the other inconveniences usually associated with today's electronic devices.
Fig.3.3. A simple handshake can transfer data.
3.2.3 Device personalization Setup, registration, and configuration information for an individual user can all be uploaded to a device the instant the device is touched, eliminating the need for the device to be registered or configured in advance.
3.2.4 New behavior patterns Tables, walls, floors and chairs can all act as conductors and dielectrics, turning furniture and other architectural elements into a new class of transmission medium. For example, a user could have instant access to the Internet merely by placing a laptop onto a conductive tabletop.
3.2.5 Marketing applications When a consumer stands in front of an advertising panel, advertising and information matching his or her attributes is automatically displayed. By touching or standing in front of items they are interested in, consumers can get more in-depth information.
Fig.3.4. A customer touching the advertising panel and getting information about that advertisement through RED TACTON device
3.2.6 Security applications Red Tacton could be installed on doors, cabinets and other locations calling for secure access, such that each secure access could be initiated and authenticated with a simple touch. At the same time, all the transaction details and relevant user attributes (personal identity, security clearance, etc.) could be logged by the security system.
3.3 COMPARISON WITH OTHER NETWORKS
The chart below shows the positioning of Red Tacton with respect to existing communication technologies. The focus on ubiquitous service has brought about the shortening of distances in communication. Red Tacton is positioned as the last 1m solution to ultimate close-range communication. Wireless communication creates connections when signals arrive, allowing for easy connections because connectors are unnecessary. However, seen from another aspect, the arriving signals can be intercepted, so security becomes an issue. Wired communication transmits data between two connection points, so interception is difficult and security can be considered to be high. However, connectors and cables are a nuisance. Taking the above points in account, Red Tacton is situated directly between wireless and wired communication. In other words, Red Tacton allows for easy connection without
connectors, while at the same time allowing transmission of data only between two contact points. It thus has the feature of being difficult to intercept.
Fig.3.5.Figure shows the comparison of RED TACTON device with other networks with respect to distance.
3.4 COMPARISON WITH OTHER COMMUNICATION METHODS
"Intra-body communication" using the human body as a transmission medium have been reported, but the electric field/photonics method employed by RedTacton is superior to conventional methods in terms of communication distance, speed, and interactivity. P: Possible N: Not possible P*: Possible under certain conditions
Table.3.1.Comparison of various methods.
3.5 ADVANTAGE OVER BLUETOOTH
The system envisioned by NTT, utilizes a conversion method which takes digital data into a stream of low-power digital pulses. These can be easily transmitted and read back through the human electric field. While it is true that similar personal area networks are already accessible by using radio-based technologies like Wi-Fi or Bluetooth, this new wireless technology claims to be able to send data over the human skin surface at transfer speeds of up to 10Mbps, or better than a broadband T1 connection. Receiving data in such a system is more complicated because the strength of the pulses sent through the electric field is so low. Red Tacton solves this issue by utilizing a technique called electric field photonics: A laser is passed though an electro-optic crystal, which deflects light differently according to the strength of the field across it. These deflections are measured and converted back into electrical signals to retrieve the transmitted data. According to Tom Zimmerman, inventor of the IBM personal networking system, body-based networking is more secure than broadcast systems, such as Bluetooth, which have a range of about 10m.The issue is that with Bluetooth, it is difficult to rein in the signal and restrict it to the device you are trying to connect to. But in a busy place there could be hundreds of Bluetooth devices within range. Moreover, body-based networking seems to allow for more natural interchanges of information between humans, as only when you are in true proximity you can make this system work. There are some specific applications that would appear as being ideal matches for Red Tacton-like technologies.

CHAPTER-IV CONCLUSION
The need for artificial body implants to communicate with each other as well as to report back to a portable device could have quite some value. In fact, according to other researchers, the most important application for body-based networking may well be for these type of communications within, rather than on the surface of, or outside, the body. Red Tacton technology is expected to dominate Bluetooth technology in the future. Red Tacton technology could put the use of cables to an end. The problem faced by the Red Tacton technology is the cost of development. This technology brings a new dimension of communication which effectively links the user to anyone he wants to communicate. Since it provides high speed communication, it can provide seamless service wherever, whenever and whoever uses it.

Abstract
This paper describes a novel networking technology, called RedTacton, developed by NTT. RedTacton could ultimately let people transfer data to each other's handhelds by means of a handshake or a slap on the back. Using a transmitter embedded in, say, a PDA, RedTacton sends a 5-volt pulse along the surface of the body. The human body shunts most of this electricity to the ground, resulting in a weak electric field that can be modulated to carry signals. The receiver is located either on another part of the body - a component of a hands-free headset or in an acquaintance's PDA. As it senses modulations in the electric field, the receiver decodes them to recover the data. While a good idea, RedTacton unfortunately has no compelling applications that aren't already available. It doesn't work reliably yet and has also been experiencing face perception problems among the general public.

INTRODUCTION:-
In an age where information is being considered as the blood of this century, the very idea of transmitting such data or information to someone very specific sends these cold waves all around our body. With so many hackers and other anti-social elements spread around the world, secure data transmission is considered to be a myth these days. With the recent technological advancements success has been achieved to an extent in tackling the above stated issue. One such solution to this issue is RED TACTON devices, which are going to make their mark very soon. And when they are out all the problems related to secure, efficient, reliable, hi speed data transmission will be solved. Yes they are going to be solved!!
WIRELESS COMMUNICATION: -
The term wireless is normally used to refer to any type of electrical or electronic operation, which is accomplished without the use of a "hard wired" connection, though they may be accomplished with the use of wires if desired. Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires". The distances involved may be short (a few meters as in television remote control) or very long (thousands or even millions of kilometers for radio communications). Wireless communications is generally considered to be a branch of telecommunications.
HISTORY: -
Human society is entering an era of ubiquitous computing, when networks are seamlessly interconnected and information is always accessible at our fingertips. The practical implementation of ubiquitous services requires three levels of connectivity: Wide Area Networks (WAN), typically via the Internet, to remotely connect all types of severs and terminals; Local Area Networks (LAN), typically via Ethernet or Wi-Fi connectivity among all the information and communication appliances in offices and homes; and Human Area Networks (HAN) for connectivity to personal information, media and communication appliances within the much smaller sphere of ordinary daily activities-- the last one meter. NTT's REDTACTON is a break-through technology that, for the first time, enables reliable high-speed HAN. In the past, Bluetooth, infrared communications (IrDA), radio frequency ID systems (RFID), and other technologies have been proposed to solve the "last meter" connectivity problem. However, they each have various fundamental technical limitations that constrain their usage, such as the precipitous fall-off in transmission speed in multi-user environments producing network congestion.
REDTACTON was developed by a seven-person research team led by Yuichi Kado, executive manager of the Smart Devices Laboratory at NTT's Microsystems Integration Laboratories, in Atsugi, west of Tokyo. Using a transmitter embedded in, say, a PDA, REDTACTON sends a 5-volt pulse along the surface of the body. The human body shunts most of this electricity to the ground, resulting in a weak electric field that can be modulated to carry signals. The receiver is located either on another part of the body”a component of a hands-free headset, perhaps”or nearby, say, in an acquaintance's PDA. As it senses modulations in the electric field, the receiver decodes them to recover the data.


WHATâ„¢S REDTACTON
For implementation of easy-to use ubiquitous services, human area network technology for communication between mobile terminals and terminals that are embedded in the environment has become important. When cables are used for communication between terminals, the routing of the cables is clearly inconvenient. When very weak radio signal is used for the communication, data speeds are reduced by packet collision and other such problems in crowded places such as exhibition sites and security risk from unwanted signal interception is another problem. Technology for solving such problems includes the use of personâ„¢s body as a signal path of communication. A transmission path is formed automatically when a person come into contact with a device, communication between mobile terminals begin. This makes it possible for communication to be initiated through natural actions such as grasping, sitting, walking and stepping onto something.
RED TACTON is a new Human Area Networking technology that uses the surface of the human body as a safe, high-speed network transmission path. REDTACTON uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared. A transmission path is formed at the moment a part of the human body comes in contact with a REDTACTON transceiver. Physically separating ends the contact and thus ends communication. Using REDTACTON, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. REDTACTON works through shoes and clothing as well.



HOW REDTACTON WORKS: -
In the past, Bluetooth, infrared communications (IrDA), radio frequency ID systems (RFID), and other technologies have been proposed to solve the "last meter" connectivity problem. However, they each have various fundamental technical limitations that constrain their usage, such as the precipitous fall-off in transmission speed in multi-user environments producing network congestion. A communications path can be created with a simple touch, automatically initiating the flow of data between a body-centric electronic device and a computer that is embedded in the environment. For example, two people equipped with REDTACTON devices could exchange data just by shaking hands.
Exactly how the receiver senses these modulations in the electric field generated by the transmitter is one of the major differences between PAN and REDTACTON. An electro-optical sensor embedded in the receiver and composed of an electro-optical crystal, a laser diode, and photodetectors reads the body's electric field through an electrode, which then transmits that field to a bismuth silicon oxide optical crystal. The electric field changes the refractive index of the crystal, which in turn changes the polarization of the sensor's laser beam as it shines through the crystal. Photodetectors register polarization changes as changes in light intensity and convert those changes into electrical signals, which are then processed by your cellphone or PDA.
Using a new super-sensitive photonic electric field sensor, REDTACTON can achieve duplex communication over the human body at a maximum speed of 10 Mbps.

REDTACTON takes a different technical approach. Instead of relying on electromagnetic waves or light waves to carry data, the technology uses weak electric fields on the surface of the body


as a transmission medium. The weak electric fields pass through the body to a receiver where the weak electric fields affect the optical properties of an electro-optic crystal. The extent to which the optical properties are changed is detected by laser light, which is then converted to an electrical signal by a detector circuit.
Using a REDTACTON electro-optic sensor, two-way communication is supported between any two points on the body at a throughput of up to 10 Mbps. Communication is not just confined to the surface of the body, but can travel through the user's clothing to a REDTACTON device in a pocket or through shoes to communicate with a REDTACTON device embedded in the floor. Unlike wireless technologies, the transmission speed does not deteriorate even in the presence of large crowds of people all communicating at the same time in meeting rooms, auditoriums or stores. Because the body surface is the transmission path, increasing the number of connected users directly increases the available number of individual communication channels.
The system works by creating a transmission path at the moment a part of the human body comes in contact with a REDTACTON transceiver. Physically separating ends the contact and thus ends communication. Using REDTACTON, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. REDTACTON even works through shoes and clothing as well.

One suggestion for the technology is for the system to be embedded into medicine bottles that would then transmit information on the medicines' attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he or she is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.
MECHANISM OF COMMUNICATION WITH REDTACTON: -
The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field.
Using a novel electro-optic sensor, Nippon Telegraph and Telephone Corporation (NTT) has already developed a small PCMCIA card-sized prototype REDTACTON transceiver. REDTACTON enables the first practical Human Area Network between body-centered electronic devices and PCs or other network devices embedded in the environment via a new generation of user interface based on totally natural human actions such as touching, holding, sitting, walking, or stepping on a particular spot. REDTACTON can be used for intuitive operation of computer-based systems in daily life, temporary one-to-one private networks based on personal handshaking, device personalization, security, and a host of other applications based on new behavior patterns enabled by REDTACTON.





REDTACTON doesn™t introduce an electric current into the body ” instead; it makes use of the minute electric field that occurs naturally on the surface of every human body. A transmitter attached to a device, such as an MP3 player, uses this field to send data by modulating the field minutely in the same way that a radio carrier wave is modulated to carry information.
Receiving data is more complicated because the strength of the electric field involved is so low. REDTACTON gets around this using a technique called electric field photonics: A laser is passed though an electro-optic crystal, which deflects light differently according to the strength of the field across it. These deflections are measured and converted back into electrical signals to retrieve the transmitted data.
The naturally occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable. The photonic electric field sensor developed by NTT enables weak electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam.
POTENTIAL APPLICATIONS: -
One-to-One services
With the ability to send attribute data from personal information devices worn on the body to computers embedded in the environment, one-to-one services could be implemented that are tailored to the individual needs of the user.

Enable one-to-one services tailored to the user's situation and tastes. Attribute information recorded in the REDTACTON device is sent to the touched objects. The appropriate service is provided based on the attribute information received by the REDTACTON receiver.


Elemenating human error:-

REDTACTON devices embedded medicine bottles transmit information on the medicines' attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.

Abstract
Much of Networking today is performed using the concept of wireless technology. Now we are furiously rising to a technique that will be more advantageous than the previous system. Networking that is performed using wired or wireless media requires high power capacities and usually meets up with traffic congestion, data loss and security problems. The new material that we have found to be sound enough to build the next generation of Networking is Red Tacton. This technology mainly enables communication between people and objects in close proximity. It enables ubiquitous services based on human-centered interactions and therefore more intimate and easier for people to use. It utilizes the surface of the human body as a safe, high speed network transmission path thus forming the concept of Human Area Networking. The embedding of Red Tacton in real time networks to perform complex networking tasks are dealt with in this paper which takes Red Tacton a step further.
Red Tacton “ A Description
In this technology communication starts by touching (Touch), leading to various actions (Act on) and the color red is added to convey the meaning of warmth in communication. Combining all the phrases we get the word Red Tacton
Principle of Communication
A Red Tacton consists of a transceiver and an electro optical sensor crystal which is used for sensing the optical property of the electrical field on the surface of the body.
RedTacton PC card prototype
RedTacton uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separating ends the contact and thus ends communication. Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. RedTacton works through shoes and clothing as well.
Using a new super-sensitive photonic electric field sensor, RedTacton can achieve duplex communication over the human body.
Principle of Red Tacton
1. The RedTacton transmitter induces a weak electric field on the surface of the body.
2. The RedTacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter.
3. RedTacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field.
4. RedTacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in an optical receivercircuit.
Mechanism of Communication
The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field.
Mechanism of Red Tacton
The naturally occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable. The photonic electric field sensor enables weak electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam.
Interesting Facts
RedTacton can achieve duplex communication over the human body at a maximum speed of 10 Mbps.
RedTacton can utilize a wide range of materials as a transmission medium, as long as the material is conductive and dielectric, which includes water and other liquids, various metals, certain plastics, glass, etc. Using ordinary structures such as tables and walls that are familiar and readily available, one could easily construct a seamless communication environment at very low cost using RedTacton.
Features of Red Tacton
RedTacton has three main functional features
(1) Touch “ Communication with just a touch or a step.
Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data.
(2)Broadband & Interactive “ Bandwidth does not deteriorate even with duplex operation and simultaneous access by many users.
Duplex, interactive communication is possible at a maximum speed of 10Mbps. Because the transmission path is on the surface of the body, transmission speed does not deteriorate in congested areas where many people are communicating at the same time.
(3) Any Media “ works with many transmission media common in human life.
In addition to the human body, various conductors and dielectrics can be used as transmission media. Conductors and dielectrics may also be used in combination.
Human Area Networking
When cables are used for communication between terminals, the routing of cables is clearly inconvenient. When very weak radio signals are used, data speeds are reduced by unwanted packet collision and other such problems in crowded places such as exhibition sites and security risk from unwanted signal interruption is another problem. All these problems have been overlooked by more robust and energy efficient technology. Using the Red Tacton, we can establish a communication network with the help of the electrical energy on the surface of the body. The network here increases with number of users in contact with each other. And this forms the cutting edge technology of the upcoming era, an era ubiquitous computing, when networks are seamlessly interconnected and information is always accessible at our fingertips both literally and metaphorically.
RedTacton “ Manner of signal transmission without loss
RedTacton does not require the electrode be in direct contact with the skin. High-speed communication is possible between two arbitrary points on the body. With the electric amperage method, a clear signal line and ground line are required. With the electric voltage method, capacity coupling can substitute. Therefore, the electrode does not have to be in direct contact with the skin.
On the other hand, photonic electric field sensors used in RedTacton can measure stand-alone contacts without being influenced by grounds. As a result, the received waveform is not distorted, regardless of the receiver location. This makes long-distance and high-speed body surface transmission possible.
Comparison of Red Tacton with other Technologies
Red Tacton surpasses other communication techniques in terms of performance and user convenience
This is depicted by a comparison table where
E stands for excellent and P stands for poor

Here the various communication techniques that are compared are

RT - Red Tacton
Transfer speed, Simultaneous access and Interactive Processing are of excellent nature in Red Tacton rather than other communication techniques.
Comparison with other Human Communication Methods
On comparison with other technologies here we apply electric field photonics which can be used for capacity coupling between equipment and the earth ground. It can communicate through any part of the body where as in other human communication system it utilizes a particular part of body for data transfer. Duplex communication can be established between mobile terminals and also between mobile terminals and external equipments.
Advantages over Bluetooth and RFID
Here the technology is clearly advantageous over Bluetooth and RFID in the following factors
(1) The Traffic and Network congestion does not occur here and it decreases with increase in number of users joining the network. It highly supports interactive processing.
(2) It greatly reduces the power consumption and cost of transmission media under usage.
(3) The data transfer rates are very impressive and it ranges to maximum of 10 Megabits per second.
(4) It turns our body into a swipe card which can be applied in security purposes.
(5) It can be applied for security purposes in a variety of domains.
Applications of Red Tacton
There are six major applications that are done using Red Tacton
(1) One to One Services
(2) Intuitive operations
(3) Personalization
(4) New Behavior patterns
(5) Security applications
(6) Communication in new domains
(1) One to One Services:
Enable one-to-one services tailored to the user's situation and tastes. Attribute information recorded in the RedTacton device is sent to the touched objects. The appropriate service is provided based on the attribute information received by the RedTacton receiver.
(A) Elimination of Human Errors
RedTacton devices embedded medicine bottles transmit information on the medicines' attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.
Examples of Similar Applications
Alert and contact record at medical, long-term care, and childcare facilities.
Avoidance of risk at construction sites (an alarm sounds if special equipment is handled by anyone other than supervisors).
(B) Marketing Applications (Context Awareness)
Touch Advertisements and receive Information
When a consumer stands in front of an advertising panel, advertising and information matching his or her attributes is automatically displayed. By touching or standing in front of items they are interested in, consumers can get more in-depth information.
Examples of Similar Applications
Brochures only of products of interest to the visitor can be downloaded automatically at trade shows.
Inside a shop, shoppers can view related information on their mobile terminals immediately after touching a product.
(2) Intuitive Operation:
Natural movements and actions are the trigger.
There's no "operation" any more. Just intuitive human interaction. RedTacton transceivers embedded in two terminals can communicate not only data but also the control or configuration instructions needed to operate devices. Cable connections are eliminated. The body itself is used as transmission medium.
Touch a printer to print
Print out where you want just by touching the desired printer with one hand and a PC or digital camera with the other hand to make the link. Complicated configurations are reduced by downloading device drivers "at first touch".
Examples of Similar Applications
Display notebook PC screen on project and implimentationors with just a touch

States, and applications of red tacton various fields. And we will compare our red tacton with the other technology for data transmission.
And know about human area network .

Introduction

We may have imagined the feature as a place crawling with antennas and emitters, due to the huge growth of wireless communications. And it is seems that the current means of transferring data might already have a very serious competitor none other than the human boby.
Thus NTT labs from Japan has announced that is currently testing a revolutionary technology called red tacton ,which use the electric fields generated by the human body as medium for transmitting the data . The chips which will embedded in various devices contain a transmitter and receiver built to send and accept data in digital format. The chips can take any type of file such as mp3 music file or mail and convert it in to the format that takes the form of digitals pulse that can be passed and read through a human being electric field .the chip in receiver devices reads these tiny changes and convert the file back into its original form.

Red tacton

Red Tacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. Red Tacton uses the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared .A transmission path is formed at the moment a part of the human body comes in contact with a Red Tacton transceiver. Physically separating ends the contact and thus ends communication Using Red Tacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. Red Tacton works natural, physical movements.

Working principle

Using a new super-sensitive photonic electric field sensor, Red Tacton can achieve duplex communication over the human body at a maximum seed of 10 mbps
The Red Tacton transmitter induces a weak electric field on the surface of the body. The Red Tacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter .Red tacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. Red Tacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in a optical receiver circuit. The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body.

The photonic electric field sensor developed by NTT enables weak electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam.
Human area network
In addition to the WANs (Internet) and LANs, there are applications best served by Human Area Networks (HANs) that connect the last meter.
Human society is entering an era of ubiquitous computing, where everything is networked.By making Human Area Networks feasible, RedTacton will enable ubiquitous services based on human-centered interactions and therefore more intimate and easier for people to use.
Feature of red tacton
Red Tacton has three main functional features.

1. TOUCH
Communication with just a touch or step

Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data. using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations through physical contact according to the human's natural movements.

2.BROADBAND & INTERACTIVE

Duplex, interactive communication is possible at a maximum speed of 10Mbps.

3.ANY MEDIA

In addition to the human body, various conductors and dielectrics can be used as transmission media. Conductors and dielectrics may also be
used in combination

DI ELETRICS CONDUCTORS

( signals pass through materials) (signals travel along surface)
.
A communication environment can be created easily and at low-cost by using items close at hand, such as desks, walls, and metal objects. But there is one limitation on the length of the conductor to be propagated, on installation locations, and on the thickness of the dielectric to be passed through.
Application fields
Many application using Red Tacton are introduced. Some are:
Red tacton devices embedded medicine bottles transmit information on the medicines' attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.

Abstract

-Human area networking (HAN) is an emerging trend
in the field of communication. Red tacton is a technology that
uses human body as a medium for transfer of data. Red tacton
uses IEEE 802.3 standard to achieve a data rate of 10Mbps. Red
tacton transceivers use the body's electrical field to transmit
digital messages. Optical crystal and laser technology converts
the changes in electrical field back into a signal at the receiver.
This method of data transfer is harmless. This method is user
friendly and fast . It also has an additional advantage of being
independent of the environment in which it is used in. The major
disadvantage posed by this method is noise interference. This
causes loss of data in other words security lapse.We use an
improved vascular pattern extraction algorithm for person
verification applications. The proposed direction-based vascular
pattern extraction (DBVPE) algorithm is based on the directional
information of vascular patterns.The solution posed by us is
towards the drawback faced by the red tacton. The best solution
is the embedded solution. This method uses the near-infrared
light , reflected or transmitted images of blood vessels of a hand
or finger are derived and used for personal recognition. The
person using the tacton has to scan his vascular pattern. For this,
we use a Micro-Controller chip and vascular pattern Image
processing is done by the micro-controller and if the image
patterns match then data flow takes place through the human
skin . If the images do not match a buzzer beeps as an alert and
data transfer is denied . This gives maximum safety to the data
present in the tacton.
