Efficient and Comfortable Haptic Retargeting With Reset Point Optimization

Passive haptics utilize the shape of a physical object to convey feedback to the user and enhance immersion in virtual reality. Haptic retargeting is a passive haptic interaction method. Its mapping of physical objects to virtual objects solves the matching problem between virtual and physical objects in the passive haptic method. However, most existing haptic retargeting methods improve efficiency without considering the important factor of user comfort. In this article, we propose an efficient and comfortable haptic retargeting method based on reset point optimization. First, we construct two maps indicating user interaction comfort: the RULA score map and the dominant hand gain map. Subsequently, we propose a reset point optimization algorithm based on these two maps. Moreover, we also optimize the selection of the physical proxy and the placement location when the reset occurs. The user study results show a significant improvement in the efficiency and comfort of our method compared to state-of-the-art methods.
