New Brain-Computer Interface , Allows Users to Play a Game , With Just Their Minds.
PsyPost reports that scientists in Spain have developed
a brain-computer interface that allowed 22 users to
play a basic multiplayer game with just their minds. .
The technology, which is based on
electroencephalograms, was found to be 94%
accurate at translating thoughts into game moves. .
The team's results were published
in 'Frontiers in Human Neuroscience.'.
PsyPost reports that brain-computer interfaces
allow direct communication between the
human brain and an external device. .

This technology interprets neural signals which are then
translated into commands that allow individuals to control
computers and other devices with just their thoughts.
The team behind the new game looked to code-modulated
visual evoked potentials, or (c-VEPs), which use
visual stimuli to elicit distinct neural responses.
Participants in the study played a version
of the game 'Connect 4,' where they alternated
dropping colored discs into a vertical grid. .

Each participant had eight electrodes
connected to their heads, which used
electroencephalographic signals as input. .
PsyPost reports that the technology has a long way
to go before it is used in commercial applications. .
Electrodes attached to a user's head
will likely have to be replaced by a more
comfortable and accessible interface.
