Virtual Reality Quidditch using a spring-based free motion haptic rig

Virtual Reality Quidditch using a custom haptic input system designed to create complete immersion. We're using a mount made from automotive shock absorber springs, an IMU to create a realistic haptic broom mount for the user. A fan and VR goggles will supplement the haptic input to create complete immersion.
