Object manipulation based on the head manipulation space in VR

Object manipulation is fundamental in virtual and augmented reality, where efficiency and accuracy are crucial. However, repetitive object manipulation tasks using the hands can lead to arm fatigue, and in some scenarios, hands may not be feasible for object manipulation. In this paper, we propose a novel approach for object manipulation based on head movement. Firstly, we introduce the concept of head manipulation space and conduct an experiment to collect head manipulation space data to determine the manipulable space. Then, we propose a new method for object manipulation based on head speed and inter-frame viewpoint quality to enhance the efficiency and accuracy of head manipulation. Finally, we design two user studies to evaluate the performance of our head-based object manipulation method. The results show that our method is feasible in terms of task completion efficiency and accuracy compared to state-of-the-art methods and greatly reduces user fatigue and motion sickness. Moreover, our method significantly improves usability and reduces task load. Our method lays a foundation for head-based object manipulation in virtual and augmented reality and provides a new manipulation method for scenarios where hands are not suitable for object manipulation.
