New Brain-Computer Interface , Allows Users to Play a Game , With Just Their Minds.<br />PsyPost reports that scientists in Spain have developed <br />a brain-computer interface that allowed 22 users to <br />play a basic multiplayer game with just their minds. .<br />The technology, which is based on <br />electroencephalograms, was found to be 94% <br />accurate at translating thoughts into game moves. .<br />The team's results were published <br />in 'Frontiers in Human Neuroscience.'.<br />PsyPost reports that brain-computer interfaces <br />allow direct communication between the <br />human brain and an external device. .<br />PsyPost reports that brain-computer interfaces <br />allow direct communication between the <br />human brain and an external device. .<br />This technology interprets neural signals which are then<br />translated into commands that allow individuals to control <br />computers and other devices with just their thoughts.<br />The team behind the new game looked to code-modulated <br />visual evoked potentials, or (c-VEPs), which use <br />visual stimuli to elicit distinct neural responses.<br />Participants in the study played a version<br />of the game 'Connect 4,' where they alternated <br />dropping colored discs into a vertical grid. .<br />Participants in the study played a version<br />of the game 'Connect 4,' where they alternated <br />dropping colored discs into a vertical grid. .<br />Each participant had eight electrodes <br />connected to their heads, which used <br />electroencephalographic signals as input. .<br />PsyPost reports that the technology has a long way <br />to go before it is used in commercial applications. .<br />Electrodes attached to a user's head <br />will likely have to be replaced by a more <br />comfortable and accessible interface.
