.doc   PROJECT OXYGEN -.doc (Size: 421 KB / Downloads: 680) THE APPROACH

INTEGRATED TECHNOLOGIES THAT ADDRESS HUMAN NEEDS

Oxygen enables pervasive, human-centered computing through a combination of specific user and system technologies.

Oxygenâ„¢s user technologies directly address human needs. Speech and vision technologies enable us to communicate with Oxygen as if weâ„¢re interacting with another person, saving much time and effort. Automation, individualized knowledge access, and collaboration technologies help us perform a wide variety of tasks that we want to do in the ways we like to do them.

Oxygenâ„¢s system technologies dramatically extend our range by delivering user technologies to us at home, at work, or on the go. Computational devices, called Enviro21s (E21s), embedded in our homes, offices, and cars sense and affect our immediate environment. Hand-held devices, called Handy21s (H21s), empower us to communicate and compute no matter where we are. Dynamic networks (N21s) help our machines locate each other as well as the people, services, and resources we want to reach.
Oxygenâ„¢s user technologies include:
The Oxygen technologies work together and pay attention to several important themes:
¢ Distribution and mobility ” for people, resources, and services.
¢ Semantic content ” what we mean, not just what we say.
¢ Adaptation and change ” essential features of an increasingly dynamic world.
¢ Information personalities ” the privacy, security, and form of our individual interactions with Oxygen.

Oxygen is an integrated software system that will reside in the public domain. Its development is sponsored by DARPA and the Oxygen Alliance industrial partners, who share its goal of pervasive, human-centered computing. Realizing that goal will require a great deal of creativity and innovation, which will come from researchers, students, and others who use Oxygen technologies for their daily work during the course of the project and implimentation. The lessons they derive from this experience will enable Oxygen to better serve human needs.
USER TECHNOLOGIES



SYSTEM TECHNOLOGIES

DEVICES AND NETWORKS

People access Oxygen through stationary devices (E21s) embedded in the environment or via portable hand-held devices (H21s). These universally accessible devices supply power for computation, communication, and perception in much the same way that wall outlets and batteries deliver power to electrical appliances. Although not customized to any particular user, they can adapt automatically or be modified explicitly to address specific user preferences. Like power outlets and batteries, these devices differ mainly in how much energy they can supply.

E21 STATIONARY DEVICES


Embedded in offices, buildings, homes, and vehicles, E21s enable us to create situated entities, often linked to local sensors and actuators, that perform various functions on our behalf, even in our absence. For example, we can create entities and situate them to monitor and change the temperature of a room, close a garage door, or redirect email to colleagues, even when we are thousands of miles away. E21s provide large amounts of embedded computation, as well as interfaces to camera and microphone arrays, thereby enabling us to communicate naturally, using speech and gesture, in the spaces they define.

E21s provide sufficient computational power throughout the environment

¢ To communicate with people using natural perceptual resources, such as speech and vision,
¢ To support Oxygen's user technologies wherever people may be, and
¢ To monitor and control their environment.

E21s, as well as H21s, are universal communication and computation appliances. E21s leverage the same hardware components as the H21s so that the same software can run on both devices. E21s differ from H21s mainly in

¢ Their connections to the physical world,
¢ The computational power they provide, and
¢ The policies adopted by the software that runs on the devices.

CONNECTIONS TO THE PHYSICAL WORLD


E21s connect directly to a greater number and wider variety of sensors, actuators, and appliances than do H21s. These connections enable applications built with Oxygen's perceptual and user technologies to monitor and control the environment.











An E21 might control an array of microphones, which Oxygen's perceptual resources use to improve communication with speakers by filtering out background noise. Similarly, it might control an array of antennas to permit improved communication with nearby H21s that, as a result of a better signal-to-noise ratio, use less power. Multiple antennas mounted on the roof of a building, as well as incoming terrestrial lines, connect through E21s to high-bandwidth, local-area N21 networks.

Through the N21 network, an E21 can connect unobtrusively to H21s in the hands or pockets of people in an intelligent space. It can display information on an H21 display in a person's hand or on a nearby wall-mounted display; it may even suggest that the person step a few feet down the hall.

H21 HAND-HELD DEVICES

Users can select hand-held devices, called H21s, appropriate to the tasks they wish to perform. These devices accept speech and visual input, can reconfigure themselves to perform a variety of useful functions, and support a range of communication protocols. Among other things, H21s can serve as cellular phones, beepers, radios, televisions, geographical positioning systems, cameras, or personal digital assistants, thereby reducing the number of special-purpose gadgets we must carry. To conserve power, they may offload communication and computation onto nearby E21s.

Handheld devices, called H21s, provide flexibility in a lightweight design. They are anonymous devices that do not carry a large amount of permanent local state. Instead, they configure themselves through software to be used in a wide range of environments for a wide variety of purposes. For example, when a user picks up an anonymous H21, the H21 will customize itself to the user's preferred configuration. The H21s contain board-level antennas that enable them to couple with a wireless N21 network, embedded E21 devices, or nearby H21s to form collaborative regions.

Project Oxygen



Introduction
For the past six months, I have been integrating several experimental, cutting-edge technologies developed by my colleagues at MIT as part of the MIT LCS/AIL Oxygen project and implimentation. This paper gives a snapshot of this work-in-progress. Project Oxygen is a collaborative effort involving many research activities throughout the Laboratory for Computer Science (LCS) and the Artificial Intellegence Laboratory (AIL) at the Massachusetts Institute of Technology (MIT). The Oxygen vision is to bring an abundance of computation and communication within easy reach of humans through natural perceptual interfaces of speech and vision so computation blends into peoples’ lives enabling them to easily do tasks they want to do – collaborate, access knowledge, automate routine tasks and their environment. In other words, pervasive, human-centric computing. At first blush, this catch-phrase appears vacuous. Today, computers are certainly pervasive; it is likely, at this moment, you are within 100 meters of a computer. Computers are certainly human-centric; what else can they be? On the other hand, computers are not yet as pervasive as is electricity or water. Although computers perform jobs required by humans, they do not feel human-centric – humans must conform to an unnatural way of communicating and interacting with computers. Finally, the tasks described have little to do with computation; computermediated functions is a more accurate term but sounds awkward. The vision and goals of the Oxygen project and implimentation are described in detail elsewhere [11, 2, 1], the purpose here is to show how many maturing technologies can be integrated as a first step towards achieving the Oxygen vision. There are research efforts at other universities and research institutions that roughly share the same vision, however, each institution focuses on integrating their own maturing technologies. Oxygen has a three-pronged approach by dividing the space into three broad categories: the H21, a hand-held device, the N21, an advanced network, and the E21, a sensor-rich environment (see Figure 1). In what follows, an Oxygen application is described in terms of its human-centric features as well as the required technologies. It is important to keep in mind that this is just one of many applications and that it is merely a vehicle to explain how many technologies can be integrated and how to create the infrastructure necessary to enable the introduction of context into applications making them more “natural” to use. The sample application is that of a seminar and presentation presentation support system. The next section gives an overview of the application. Section 3, reviews many of the technologies that will go into this application. Section 4, shows how they integrate to form the application. A preliminary programming language and middleware support is described .
Acomputer-mediated, seminar and presentation presentation system
This section describes a computer-mediated seminar and presentation presentation system. As you read through the description, compare it to how presentations are given today. Although a laptop with programs like Powerpoint or Freelance attached to an LCD project and implimentationor is a vast improvement over the old days of foils or 35mm slides, the human has given up a degree of control, freedom, and naturalness. The system described below provides for a more natural human interface. Alice is to give a seminar and presentation about her O2.5 project and implimentation. As she walks into the seminar and presentation room, she allows herself to be be identified as the speaker. She does not need to carry a laptop with her slides on it – all of her files are globally accessible. Alice tells the system how to find her talk by simply supplying enough keywords to uniquely identify the file she wants. Her files are well indexed and so she merely describes the file in human terms and not with some bizarre syntax. The system knows where she is and marshals all the physical components that may be needed for her to control the display. Alice wants to control the display so that it matches her current desires. A seminar and presentation is a live event and the dynamics depend on the audience and speaker. Although it is crucial that she control the presentation, this control should be of minimal distraction. The same is true for the audience – they should be able to see the visual content, hear her commentary, and take notes at the same time. Moreover, unexpected events should be handled in a natural way. Even today, Oxygen technologies can make a computer-mediated presentation a more natural experience. In particular, three natural ways to control the slides are provided, as opposed to the traditionally way where Alice either clicks the mouse or hits the enter key. It is computer-centric to force the speaker to always walk over to the laptop in order to advance the slide. A wireless mouse is only a partial solution as it requires that something be held in a hand. For Bob this might be fine, but Alice likes to use a laser pointer to highlight objects on the screen and she finds holding two objects to be very awkward. An integrated pointer/mouse is no better since it now requires attention to find the correct button. Alice can use her laser pointer to highlight words, draw lines and sketches, as well as to switch between slides. Holding the pointer in the bottom right corner means to advance to the next slide. A camera looking at the screen interprets Alice’s laser pointer gestures. But not all humans like to use laser pointers. Some people, especially when they

are continuously engaged in speaking, like to use verbal commands to control the presentation. This is done with a microphone and software that continuously tries to understand commands. All three modes of control will always be active, allowing the speaker to use whatever is convenient.
There is more to a presentation than just advancing slides. Alice may want to see her notes, see the next slide before the audience, skip a slide or present the slides in a different order. A laptop, handheld, or any other personal communication device can be used by the speaker. To skip to a different slide without anyone knowing it, is a task that is easily performed by simply clicking on a different slide image on her personal display. The personal display must remain consistent with the public display. So, whether Alice says “Next Slide,” chooses a slide from her private computer (handheld or laptop), or uses the laser pointer, both displays are updated.
The audience should also have a choice of ways to observe the presentation. They can look at the large project and implimentationion screen in the front of the room, as is usually the case, or they may choose to view the presentation on their own personal digital device. The output is simultaneously broadcast to these devices. Some people in the audience might like to take notes and have them correlate with the presentation itself. We propose broadcasting a URL or some other identification symbol for the current contents. This can be either used to display the slide on the laptop, or be inserted into their notes. Later on in the privacy of their own room, these notes can be merged with an archived version of the talk. The archived version will match the presentation rather than the original file. Alice may have many “emergency” slides prepared that will be shown only in response to a question. To summarize, there are several output modalities: the LCD project and implimentationion, a broadcast of the current content, an archival copy that can be accessed afterwards, and the ability to correlate the public presentation with her own personal view of the presentation.
Lastly, Alice also has “meta” operation control - e.g. switching to a different presentation package, such as a browser or Mathematica, or even to the contents of another presentation. She should also be able to control whether or not content is broadcast or archived.

Technology overview
Research into many technologies that support the above scenario being pursued as part of Project Oxygen. Once again, we wish to emphasize that there are many competing technologies being developed elsewhere. We deliberately ignore them for several reasons1. First, to do justice to them all would make this article too large. Second, close physical proximity is usually required when making use of experimental, research systems. While it is possible to do this remotely for one component, it is nearly impossible do this for a number of research project and implimentations. We wish to provide feedback to these other research project and implimentations before they are ready for prime-time and we deliberately try to use them in some unintended way. While there are similar efforts in many of the intelligent or instrumented rooms, our example is simply geared towards exposing how components interact even with commodity hardware. As fun as it is, the particular demo of an oxygenated presentation is not the goal

Project Oxygen


.docx   1Project Oxygen.docx (Size: 313.75 KB / Downloads: 20)

WHAT IS PROJECT OXYGEN?

Michael Dertouzos, late director of MIT’s famed Laboratory for Computer Science, had a vision: pervasive, human-centered computing. “We find ourselves in the junction of two interrelated challenges: Going after the best, most exciting forefront technology; and ensuring that it truly serves human needs,” he wrote in the lab’s mission statement. Last year, the LCS-together with MIT’s Artificial Intelligence Laboratory-launched an ambitious effort to build that vision, called Project Oxygen.

HISTORY:

For over forty years, computation has centered about machine no people. We have catered to expensive computers, pampering them in air-conditioned rooms or carrying them around with us. Purporting to serve us, they have actually forced us to serve them. They have been difficult to use. They have required us to interact with them on their terms, speaking their languages and manipulating their keyboards or mice. They have not been aware of our needs or even of whether we were in the room with them. Virtual reality only makes matters worse: with it, we do not simply serve computers, but also live in a reality they create.

Approach:

Oxygen enables pervasive, human-centered computing through a combination of specific user and system technologies. Oxygen's user technologies directly address human needs. Speech and vision technologies enable us to communicate with Oxygen as if we're interacting with another person, saving much time and effort. Automation, individualized knowledge access, and collaboration technologies help us perform a wide variety of tasks that we want to do in the ways we like to do them.
Oxygen's device, network, and software technologies dramatically extend our range by delivering user technologies to us at home, at work or on the go. Computational devices, called Enviro21s (E21s), embedded in our homes, offices, and cars sense and affect our immediate environment. Handheld devices, called Handy21s (H21s), empower us to communicate and compute no matter where we are. Dynamic, self-configuring networks (N21s) help our machines locate each other as well as the people, services, and resources we want to reach. Software that adapts to changes in the environment or in user requirements (O2S) help us do what we want when we want to do it.

Oxygen Device Technologies:

Devices in Oxygen supply power for computation, communication, and perception in much the same way that batteries and wall outlets supply power for electrical appliances. Both mobile and stationary devices are universal communication and computation appliances. They are also anonymous: they do not store configurations that are customized to any particular user. As for batteries and power outlets, the primary dif ference between them lies in the amount of energy they supply.

Oxygen Network Technologies:

Networks, called N21s, connect dynamically changing configurations of self-identifying mobile and stationary devices to form collaborative regions. N21s support multiple communication protocols for low-power point-to-point, building-wide, and campus-wide communication. N21s also provide completely decentralized mechanisms for naming, location and resource discovery, and secure information access.

Oxygen Software Technologies:

The Oxygen software environment is built to support change, which is inevitable if Oxygen is to provide a system that is adaptable, let alone eternal. Change is occasioned by anonymous devices customizing to users, by explicit user requests, by the needs of applications and their components, by current operating conditions, by the availability of new software and upgrades, by failures, or by any number of other causes. Oxygen's so ftware architecture relies on control and planning abstractions that provide mechanisms for change, on specifications that support putting these mechanisms to use, and on persistent object stores with transactional semantics to provide operational support for change.

Oxygen perceptual Technologies:

Speech and vision, rather than keyboards and mice, provide the main modes of interaction in Oxygen. Multimodal integration increases the effectiveness of these perceptual technologies, for example, by using vision to augment speech understanding by recognizing facial expressions, lip movement, and gaze. Perceptual technologies are part of the core of Oxygen, not just afterthoughts or interfaces to separate applications. Oxygen applications can tailor "lite" versions of these technologies quickly to make human-machine interaction easy and natural. Graceful interdomain context switching supports seamless integration of applications.
