Develop wheelchair controlled by brain waves

Develop wheelchair controlled by brain waves

On more than one occasion we stopped in investigations that deal with the study of the brain’s electrical activity and the use of brain waves . This type of research is very interesting because they open the door to the development of multiple systems can significantly improve the quality of life of people suffering from some form of paralysis or even improve car safety . One of the objectives that are marked many of these investigations is to use EEG signals to monitor objects and, for example, controlling the movement of a wheelchair . Precisely in this sense has long been working on Professor Hung Nguyen and his son, who have successfully tested a that can “control the mind” .

The wheelchair functions both autonomously (carrying the user through a host using) as guided manner, using as input signal the brain electrical activity of the user of the wheelchair, and it is the latter form of control the Most of this research (although not rule continue working in the autonomous management). The project began several years ago when the son of Professor Hung Nguyen, Dean of the Faculty of Engineering of the University of Technology Sydney (Australia), Jordan (who also holds the same university and is supervisor of several students), had an accident in a pool for 7 years I was convalescing for some time:

I was lucky not to break my neck but, in the case of being paralyzed from the neck down, there is a very narrow spectrum of technologies to use

Why work with a wheelchair? According to Professor Nguyen, there is a great demand for this type of system, and since has over 20 years in the use of EEG as input signal and control systems, decided invest in the development of a wheelchair but, over time, come feasible that such control systems can be used to control car (something that was already doing Nissan in collaboration with Ecole Polytechnique Federale de Lausanne) or even appliances.

Is a series of sensors placed in the neck of the user to capture the electrical signals generated in the brain and processing. The system decodes the electrical signals and is able to interpret certain commands such as “left” or “right” to move the chair provided this confirmation of an order closing his eyes for a few seconds

For now, the wheelchair has successfully passed a series of clinical trials to determine its operation and, it seems, the design could be ready to be manufactured and marketed though, to get to this point, still have to wait one to five years to get the necessary funding.
