Swiss Researchers are making extreme progress within the field of neuroprosthetics (a.k.a. devices controlled by the brain). The Brain-powered wheelchair by EPFL is the latest technology that gives the user control, using their mind.
Measuring EEG readings to sense brain patterns, it also includes artificial intelligence to give "shared" control to the rider, and allow for a more sophisticated ride. The wheelchair is capable of detecting objects using image-processing software, and can avoid them easily. The technology is capable of differentiating between certain objects as well, such as a desk or cabinet.
