Development of a non-grounded haptic interface using the gyro effect

In this paper, we propose a technique capable of generating haptic sensation in a human-scale virtual reality environment or in an augmented reality environment. To realize such a large working volume and the ability to move easily within it, we have developed a non-grounded haptic interface using the gyro effect. The interface consists of a flywheel equipped with motor controlled gimbals that tilt the flywheel. We also propose three haptic rendering methods that can provide information regarding territories, target direction and trajectory. The effectiveness of our haptic interface was tested by conducting a series of experiments.
