Mid-Air Display for Physical Exercise and Gaming

We present some possibilities and our experiments with the "immaterial" walk-through FogScreen for gaming and physical exercise. We use real-time 3D graphics and interactivity for creating visually and physically compelling games with the immaterial screens. An immaterial projection screen has many advantages for physical exercise, games and other activities. It is visually intriguing and can also be made two-sided so that the opposing gamers on each side see both their side of the screen and each other through it, and can even walk through it. The immaterial nature of the screen helps also on maintenance, as the screen is unbreakable and stays always clean. The initial results show that the audience stayed with the game over extended periods of time. The overall comments of the gaming and physical exercise environment were positive and it was generally assessed to be captivating and inspiring.
