Visual Feedback for Grasping in Virtual Reality Environments for an Interface to Instruct Digital Human Models

Digital Human Models (DHMs) are widely used in big industry whereas they are not used in small and medium-sized enterprises. One of the main reasons is the complexity and usability. Engineers need a notable amount of training to be able to use DHM software. The authors suggest a new interactive Virtual Reality (VR) interface to instruct DHMs. Within this VR environment, engineers can naturally interact with virtual objects using their hands. These interactions are used as an instruction for DHMs. To support the software user best it is necessary to provide feedback to be able to grasp the virtual object most efficiently. In this work we present a user study in which we investigate which visual feedback leads to the best performance for grasping virtual objects. The results show that users are supported most when additional Hand Color Feedback is provided in the VR environment.
