Access Invaders played using vision–based gesture recognition
A standard web camera is used to track hand movement and recognize palm and finger gestures (watch the video – 12MB). This module was developed by the Computational Vision and Robotics Laboratory (CVRL) of ICS–FORTH.
Access Invaders played using musical input
Individual musical notes, irrespectively of the instrument used to produce them (e.g., by whistling, knocking a spoon against a glass, playing the guitar or the piano, or even singing) are recognised and mapped to game controls (watch the video – 5MB).
