Mind Reading Computer

Introduction:

People express their mental states, including emotions, thoughts, and desires, all the time through facial expressions, vocal nuances and gestures. This is true even when they are interacting with machines. Our mental states shape the decisions that we make, govern how we communicate with others, and affect our performance. The ability to attribute mental states to others from their behavior and to use that knowledge to guide our own actions and predict those of others is known as theory of mind or mind-reading.
Existing human-computer interfaces are mind-blind — oblivious to the user’s mental states and intentions. A computer may wait indefinitely for input from a user who is no longer there, or decide to do irrelevant tasks while a user is frantically working towards an imminent deadline. As a result, existing computer technologies often frustrate the user, have little persuasive power and cannot initiate interactions with the user.
Even if they do take the initiative, like the now retired Microsoft Paperclip, they are often misguided and irrelevant, and simply frustrate the user. With the increasing complexity of computer technologies and the ubiquity of mobile and wearable devices, there is a need for machines that are aware of the user’s mental state and that adaptively respond to these mental states.
The mind-reading computer system presents information about your mental state as easily as a keyboard and mouse present text and commands. Imagine a future where we are surrounded with mobile phones, cars and online services that can read our minds and react to our moods. How would that change our use of technology and our lives? We are working with a major car manufacturer to implement this system in cars to detect driver mental states such as drowsiness, distraction and anger.

What is mind reading

A computational model of mind-reading

Drawing inspiration from psychology, computer vision and machine learning, the team in the Computer Laboratory at the University of Cambridge has developed mind-reading machines — computers that implement a computational model of mind-reading to infer mental states of people from their facial signals. The goal is to enhance human-computer interaction through empathic responses, to improve the productivity of the user and to enable applications to initiate interactions with and on behalf of the user, without waiting for explicit input from that user.

Why mind reading

The mind-reading computer system presents information about your mental state as easily as a keyboard and mouse present text and commands.

We are working with a major car manufacturer to implement this system in cars to detect driver mental states such as drowsiness, distraction and anger.

How does it work

The mind reading actually involves measuring the volume and oxygen level of the blood around the subject's brain, using technology called functional near-infrared spectroscopy.
The user wears a sort of futuristic headband that sends light in that spectrum into the tissues of the head where it is absorbed by active, blood-filled tissues. The headband then measures how much light was not absorbed, letting the computer gauge the metabolic demands that the brain is making.The results are often compared to an MRI, but can be gathered with lightweight, non-invasive equipment.
Wearing the fNIRS sensor, experimental subjects were asked to count the number of squares on a rotating onscreen cube and to perform other tasks. The subjects were then asked to rate the difficulty of the tasks, and their ratings agreed with the work intensity detected by the fNIRSsystemupto83percentof the time.
"We don't know how specific we can be about identifying users' different emotional states," cautioned Sergio Fantini, a biomedical engineering professor at Tufts. "However, the particular area of the brain where the blood-flow change occurs should provide indications of the brain's metabolic changes and by extension workload, which could be aproxyforemotionslikefrustration.

Advantages and uses

Mind Controlled Wheelchair

This prototype mind-controlled wheelchair developed from the University of Electro-Communications in Japan lets you feel like half Professor X and half Stephen Hawking—except with the theoretical physics skills of the former and the telekinetic skills of the latter.A little different from the Brain-Computer Typing machine, this thing works by mapping brain waves when you think about moving left, right, forward or back, and then assigns that to a wheelchair command of actually moving left, right, forward or back.
The result of this is that you can move the wheelchair solely with the power of your mind. This device doesn't give you MIND BULLETS (apologies to Tenacious D) but it does allow people who can't use other wheelchairs get around easier. The sensors have already been used to do simple web searches and may one day help space-walking astronauts and people who cannot talk. The system could send commands to rovers on other planets, help injured astronauts control machines, or aid disabled people.
In everyday life, they could even be used to communicate on the sly - people could use them on crowded buses without being overheard.The finding raises issues about the application of such tools for screening suspected terrorists -- as well as for predicting future dangerousness more generally. We are closer than ever to the crime-prediction technology of Minority Report.
The day when computers will be able to recognize the smallest units in the English language—the 40-odd basic sounds (or phonemes) out of which all words or verbalized thoughts can be constructed. Such skills could be put to many practical uses. The pilot of a high-speed plane or spacecraft, for instance, could simply order by thought alone some vital flight information for an all-purpose cockpit display. There would be no need to search for the right dials or switches on a crowded instrument panel.
