Game creator Lat Ware’s first person action game, Throw Trucks with Your Mind, uses an EEG headset to combine traditional controls with the player’s brain waves. The better a player can control their own beta brainwaves and remain in a state of calm focus, the better they will play. From Polygon:
When Polygon first met Ware in June 2013, Throw Trucks With Your Mind was still a proof of concept, but it demonstrated what Ware and his team were trying to achieve. Ware wanted to empower players with Jedi-like powers. In the original demo, players could move around in the game and aim at objects through traditional mouse and keyboard controls, but the act of moving in-game objects was executed with the mind. This was done through the EEG headset, which tracked the player’s focus and calm. The more focused a player was, the more powerful they were in the game.
“The game doesn’t know what you’re thinking, it only knows how you’re thinking,” Ware recently told Polygon. “So if you wanted to pick something up, you would select the lift power, you’d aim it at the thing you want to lift, you’d hold the left mouse button and, the more mentally calm you are, the stronger the upward force on the center of mass of the object.
