The field of brain-computer interface research has been rapidly
expanding in recent years and has a wide range of interesting and
compelling uses. EEG-based brain-computer interfaces currently allow
users to type, play games, create music or control prosthetic limbs.
Brainathlon is an open source software game that is controlled
by players' brainwave activity. An electroencephalogram (EEG) monitors
the player's brainwaves. These waves are fed into the computer,
analyzed and used to control the game play.
Like a triathlon, Brainathlon consists of 3 separate mini-games,
called courses. Each course provides users with real-time feedback
on current brain activity and rewards activity in configurable frequency
ranges. A single user can play the game alone, or two players can
compete against each other. When played in two-player mode, the
player who wins the most courses will win the game. This game can
be used to gain conscious control of brainwave activity and to increase
wave frequencies associated with certain mental states such as relaxation
or mental focus.
The Reusable Libraries
The Brainathlon software includes a reusable library of EEG monitoring,
filtering and analysis tools that can be used to create future EEG-based
applications. The software was built to work with ModularEEG,
an open source brainwave monitoring device. The reusable Brainathlon
libraries provide software developers with a toolkit to facilitate
the creation of inexpensive brain-computer interface applications
for the ModularEEG device.
