With
the GT3D device which costs about £50 (N 12,500.00), people with
nervous disorder can now use their eyes to control the computer.
The GT3D
device is made up of two fast video game console cameras that are positioned,
outside of the line of vision to a pair of glasses. The cameras constantly take
pictures of the eye, working out where the pupil is pointing, and from this a
set of calibrations can be used to work out exactly where a person is looking
on the screen.
The device
makes it possible for the user to type, click on and pick objects on the
screen, as well as play video games.
It is also
being developed to make possible control of computerized wheelchair, and other
human aid to cater for people with varying health challenges.
