A biofeedback game is a video game that uses an EEG (electroencephalography) machine to read brainwaves. This mechanism can allow a player to control parts, or possibly all, of the game with their mind. In most cases, a game controller is still needed for some tasks and controls.
Biofeedback games are not mainstream, primarily due to higher costs of EEG devices and required time to “teach” the device and game how to read their brainwaves.
