6DOF Whole-Hand Haptic Interaction System Based on Hybrid Grasping Approach

Although haptic interaction which provides direct touch sensation is the most natural way of interacting with VR environment, existing haptic solutions are not yet fully satisfying due to the interaction problems such as the hand penetration, frictionlessness, lack of visual feedback, and so on. Among these problems, the hand penetration problem which is an effect sinking into a virtual object is the most visually distracting artifact in grasping, and it is mainly caused by the incomplete physical capabilities of haptic devices and poor grasping manipulation. To address this problem, we have developed a realistic haptic interaction system, which consists of the new 6DOF whole-hand hardware combined with a glove-type device, and propose a hybrid grasping method which intelligently uses both heuristic and physics-based approach.

High-Precision hand interface

Virtual reality techniques have been introduced to propose the intuitive interface in virtual entertainment environments. We introduce the intuitive and natural interaction interface supporting the high-precision hand operations. In this paper, we describe the novel sensing mechanism of finger tracking with fast refresh rate and high resolution.
