Demonstration of ElastOscillation: A VR Controller Providing 3D Multilevel Feedback for Damped Oscillation

We propose ElastOscillation, mounted on a virtual reality (VR) controller to provide 3D multilevel force feedback for damped oscillation to enhance VR experiences. ElastOscillation consists of a proxy, six elastic bands and DC motors. It leverages the motors to control the bands' elasticity to restrain the movement of the proxy, which is connected with the bands. Therefore, when users shake the ElastOscillation device, the proxy shakes or moves in the corresponding movement ranges or levels. The users then perceive the force from oscillation in different levels. In addition, elastic force from the bands further reinforces the oscillation force feedback. In the demonstration, users can explore four VR applications that feel the sensation of pan-flipping, bartender-shaking, wine-swirling and fishing.
