The system is based on a multilevel dynamic Bayesian network classifier which models cognitive mental states as a number of interacting facial and head displays. Experimental results yield an average recognition rate of 87. 4% for 6 mental states groups: agreement, concentrating, and disagreement.
Interested, thinking and unsure. If we could learn to Identify brain waves generated by specific thoughts or commands, we might be able to teach the same skill to a computer. The machine might even be able to react to those commands by, say, moving a dot across a TV screen.So far the S. R. I, computer has en taught to recognize seven different commands-?up, down, left, right, slow, fast and stop.
A computer can, in a very real sense, read human minds. Although the dot's gyrations are directed by a computer, the machine was only carrying out the orders of the test subject. Though computers can solve extraordinarily complex problems with incredible speed, the information they digest is fed to them by such slow, cumbersome tools as typewriter keyboards or punched tapes.Mind reading allows us to make sense of other people's behavior, predict what they might do next, ND how they might feel. The ability to mind reading abilities are thought to be the primary Inhibitor of emotion and social understanding in people diagnosed with autism. People express their mental states, Including emotions, thoughts, and desires, all the time through facial expressions, vocal nuances and gestures.
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.With the increasing complexity of computer technologies and he ubiquity of mobile and wearable devices, there Is a need for machines that are aware of the users 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. We are working with a major car manufacturer to implement this system in cars to detect driver mental states such as drowsiness, castration and anger.
Mind-reading machines -? computers that implement a facial signals. Using a digital video camera, the mind-reading computer system analyses a person's facial expressions in real time and infers that person's underlying mental state, such as whether he or she is agreeing or disagreeing, interested or bored, thinking or confused. For example, a combination of a head nod, with a smile and eyebrows raised might mean interest. We are also looking at the use of mind- reading to support on-line shopping and learning systems.A computer program which can read silently spoken words by analyzing nerve signals in our mouths and throats has been developed by NASA. Currently, the "mind-reading" computer is being shown at the Royal Society Summer Science Exhibition in London, where the developers are using the exhibition's visitors to build up the computer's database.
In order for the computer to read minds, it needs thousands of samples to more accurately read one's emotions. So far, the computer's database is full of actors' faces doing their best to express Joy, sorrow, anger, confusion and other emotions.
