Emotiv

The Emotiv headset is a personal computer interface that works by detecting facial expressions and electric signals produced by the brain. Some of the applications currently compatible with the Emotiv include games that give players the fantasy of having supernatural powers and an onscreen keyboard that allows people with locked-in syndrome to communicate. Eventually the technology could be used to control all aspects of our computers, as well as robots or smarthouse technologies in the real world. The day might be coming when you can turn on lights and open doors with a simple thought. There are clear accessibility applications for this technology, and indeed Emotiv is developing an electric wheelchair interface that allows users to drive by means of their facial expressions and thoughts.
