Ourdesign uses video input from a camera to detect the motion of the player and translates this motioninto positional data to control the player’s gun position. A player uses arm gestures to trigger thegun by raising and then lowering his arm. This game play concept was inspired by the recent useof video games as exercising aids. Our objective was to give the player a workout while enjoying aclassic video game.The Paratroopers video game has a simple objective, which is to destroy enemy helicopters,bombs and paratroopers as they appear on the screen. During the game the helicopters releasebombs and paratroopers at random positions while moving …
