Airbrush is a group game in which one player draws a word, and the rest of the group has to guess what he or she is drawing.
To draw, the player uses the smartphone as a mouse, and the telephone communicates its exact position in relation to the TV to the STB. Instead of using a native app, the game uses a web app that can read the smartphone’s gyroscope.
The phone’s position is then sent to the STB via MAF rooms (websockets). The app on the STB receives the positions and draws the phone’s movements on Canvas (2D context).
