Title
ElastOscillation: 3D Multilevel Force Feedback for Damped Oscillation on VR Controllers
Abstract
Force feedback from damped oscillation is a common effect in our daily lives, especially when shaking an elastic object, an object hanging or containing other stuff, or a container with liquid, e.g., casting with a fishing pole or wine-swirling. Such a force, affected by complex physical variations and collisions, is difficult to properly simulate using current force feedback methods. Therefore, we propose ElastOscillation 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 corresponding ranges of movement. The users then perceive the force from oscillation at different levels. In addition, elastic force from the bands further reinforces the oscillation force feedback. We conducted a force perception study to understand users' distinguishability for perceiving oscillation forces in 1D and 2D movement, respectively. Based on the results, we performed a VR experience study to show that the force feedback provided by ElastOscillation enhances VR realism.
