Atari Mindlink

[1] The Mindlink was unique in that its headband form factor controls the game by reading the myoneural signal voltage from the player's forehead.

Three games were in development for the Mindlink by its cancellation: Bionic Breakthrough, Telepathy, and Mind Maze.

Bionic Breakthrough is basically a Breakout clone, controlled with the Mindlink.

Mind Maze uses the Mindlink for a mimicry of ESP, to pretend to predict what is printed on cards.

Testing showed that players frequently got headaches[4] due to moving their eyebrows to play the game.
