The system uses a set of microelectrodes implanted in the brain that declines in real time the neural signals associated with the intention of moving a limb. The three people who participated in the experiment had an electrode mesh implanted over a portion of its motorcortex brain area that helps control movement ̵
1; which picked up neural activities indicating that they were planning to move a marker on the screen. These patterns were then sent to a virtual mouse that was wirelessly attached to the tablet.
By using only their intentions, participants could perform a series of common digital tasks, including web search and send email. One participant ordered food online and played a digital piano. “The tablet became the second nature for me, very intuitive,” she told the researchers when she asked her experience, according to the study. The system even allowed two of the participants to chat with each other in real time.
Of course, the interface technology for brain computers has been around for a few years. What is remarkable about this study, however, is that BrainGate2 allows users to navigate completely unmodified devices without tribute without any special features or modifications. And some basic tweaks can make the system even more accessible to users.
According to the study reports, “Participants conveniently visited the user interface, even though they did not have access to all the gestures commonly used on a tablet (such as click and drag, multitouch). This excludes some features like rolling up and down the tabletop browser. Some of these restrictions would have been overcome by enabling accessibility features contained in Android OS or third-party applications. In addition, the Android OS keyboard layout as we have done in previous reports would have assumed increased typing. “
The result, however, shows how communication, mobility and independence can be partially restored to those who otherwise have limited control over their environment and without the need for expensive or specialized equipment – a major development that will have a huge positive impact on the lives of people around the world.
