AirCurve Project
by Christian Hulleman and Gerjan Konterman
AirCurve is an innovative multiplayer game that uses the webcam to control the players. The game is made in XNA Framework 4.0 and is based on Achtung die Kurve a.k.a. Zatacka (http://flashkurve.com/).
As said, to control the player (which is a growing line) the game uses the webcam for detecting moving objects (markers). For this we used the TouchlessSDK (http://touchless.codeplex.com/).
The idea is to choose a certain object with a good contrast and set this as a 'marker' that you will you use to control your player, for example a red finger. We made small paper finger-hats which we used as the controls for the game.
When the markers are set for each of the players, than you can control your player by just moving your finger 'in the air'. As of now, it only supports 2 players and 2 directions (left and right).
