Evaluation of Hand-Based Interaction for Near-Field Mixed Reality with Optical See-Through Head-Mounted Displays

Hand-based interaction is one of the most widely-used interaction modes in the applications based on optical see-through head-mounted displays (OST-HMDs). In this paper, such interaction modes as gesture-based interaction (GBI) and physics-based interaction (PBI) are developed to construct a mixed reality system to evaluate the advantages and disadvantages of different interaction modes for near-field mixed reality. The experimental results show that PBI leads to a better performance of users regarding their work efficiency in the proposed tasks. The statistical analysis of T-test has been adopted to prove that the difference of efficiency between different interaction modes is significant.
