We have a blog where we share sketches and project ideas in new media and interaction design. The latest contribution is Face Twitch, a reaction-time game built during a tech workshop on rapid prototyping techniques combining Arduino and Bluetooth.
How Face Twitch works
The cell phone displays an image of a face. If it is a happy face, the player to press her button first gets a point. If it is a sad face, pressing the button costs a point. First player to reach five points wins.
