MYTH BUSTED: Control a tablet with NO HANDS!!

Advances are approaching at an alarming rate with brain computer interfaces. When we think of tablets and hand-held devices, we never imagine using these devices without hands. Scientist at Stanford University have made this possible with neuro-engineering. A patient who goes by “T6” for confidentiality purposes, suffers from amyotrophic lateral sclerosis (also known as Lou Gehrig’s disease), which causes progressive motor neuron damage. Like T6, many people around the world live with  paralysis from spinal cord injury, stroke or neuro-degenerative diseases. These disease diminish the quality of life as people cant communicate simple thoughts or motives to the people around them.

This developing technology has many helpful components. Eye- or head-tracking components are used to translate eye movement to cursor and pointing movements on electronic devices. This is done with the transference of brain waves from the brain, to the eye, and then to the tablet. This technology even has the capabilities of recording your intent and acting for you. An example of this phenomena is how the user in this study could also perform the click function by staring intently at a single spot, known in the field as “dwell time”.

This effort was a part f the BrainGate clinical trials, and further efforts are invested to make these technology uses clinically feasible.
