SPANISH SCIENTIST INVENT WHEEL CHAIR THAT CAN BE CONTROLLED BY SIMPLY THINKING

Spanish scientists managed to create a wheelchair that a
person can control by simply thinking about the desired
destination. People who have disabilities that prevent them
from using the joystick can control this latest invention in
technologyby simply thinking where they want to go.
The wheelchair features a laser scanner that helps create a
3D image of the surroundings. The image that shows the area
around is displayed on a screen installed in front of the
user, who needs to concentrate on the part of the screen
where they wish to go and the wheelchair acts in response.
In order to identify the brain activity of the user, researchers
use askullcapthat helps work out the destination they want
to go to.
The engineer, who came up with the idea of developing a
wheelchair that can be controlled by the mind, is Dr Javier
Minguez from theUniversity of Zaragozain Spain. He
mentioned that it took only 45 minutes for the study
participants to learn to control the device.
This is the latest invention to be controlled with the help of
thought. But the wheelchair prototype is still not ready to hit
the stores, due to the fact that it can only handletwo
thoughts every minute. Researchers look forward to creating
faster and more complex versions in future.
