Photoelastic Ball

Balls are a key equipment for sports and entertainments such as juggling, etc. Then, much research has been conducted for developing balls of the next generation to enhance ball related entertainments. Such balls have plenty of special effects such as sound and light, but have limited input method. Those effects are often controlled through ball's native motion by using accelerometers, etc. However, as increasing the variety of special functions of such balls, the appropriate input method should be required. In this research, we developed a force vector sensor sheet unit that can be implemented on the surface of the ball. In this paper, we report the detail of the sensory system and its experimental results.
