Lazybrains is a 3D game with both a bridge between a neuro-monitoring device and a gaming engine. The game explores the influence that new methods of interfacing may have on a user's immersion in an interactive 3D world, as well as new elements of game-play that may arise. The game is to be an exploratory, level-based experience where the user guides their character through different chambers, each offering a challenge which uses feedback from the player's brain as an additional input device. Utilizing the fNIR device, the user's brain activity becomes an additional "controller". In addition to standard controls on a traditional keyboard and mouse interface, the user's biofeedback output manipulates factors in the game's environment. For example, the user's particular concentration level may manipulate the height of platforms, slow down the motion of obstacles, or even change the color of virtual puzzle pieces to complete objectives.
