Phone Control is a multi-user software system that turns your cellphone into a control pad. To demonstrate the system's functionality we created a simple bumper car game.
Each time a user calls a phone number displayed on-screen, a new car is introduced in the game. This car can then be moved around the screen by pressing keys on that user's phone.
The last car remaining wins the game. To eliminate other cars, a user must bump into other cars. To score points, a user's car must be moving faster than the car they hit.
The system can be used for any multiplayer game or collaborative system displayed in a public space.
