In Singapore, the Society of Physically Disabled and the Institute of Infocomm Research are embarking on a project to allow severely handicapped persons to communicate via brainwaves. The move will benefit those who suffer from total mobility and speech impairment problems.

The letters of a keyboard are flashed in a pre-determined sequence, and the brain’s reactions are recorded by a electroencephalogram sensor worn by the receiver. When s/the patient sees the letter that s/he wants, the brain automatically registers a spike in electrical activity.

The Brainy Communicator is still in its infancy and the process is slow: scientists expect users to be able to type just five characters per minute. Besides, users require steady concentration for better accuracy and current equipment is too cumbersome for everyday use.

However, under lab conditions, accuracy can surpass the 95 percent targeted by scientists.

According to the developers, the project is expected to take two years. At the end of 2006, two to five working prototypes should be ready, with perhaps the chance that a manufacturer will commercialize the technology.

Converting brainwaves into letters is only the first step. Maybe in time, patients will be able to control wheelchairs with just their minds. The technology may also find a willing mass market in gaming and digital homes.
