Motion Instruction Method Using Head Motion-Associated Virtual Stereo Rearview†
AbstractIn recent years, virtual reality (VR) technologies have been increasingly used for teaching motion skills to learners. In this paper, the authors employed a VR assistive system for teaching motion skills to learners by the use of an inertial sensor-embedded head-mount-display (HMD). As a step of the development, we studied a motion instruction method using “Head Motion-Associated virtual stereo Rearview (HMAR in short)”, and conducted a study on pose-recognition under a time-consuming vision-restricted condition. Under this condition, subjects were to ensure their remembrance only by vision and taking enough time, and not by using proprioception. The time consuming condition is considered to be antithetical to the instantaneous less time consuming condition, and is expected to contribute to deepening the understanding of the effect of the HMAR. In the experiment, reference poses are displayed to learners with the use of a VR system. In the system, the learners observe the virtual stereo rearview via HMD, and perceive and reproduce the displayed reference poses. Here, the virtual stereo camera that is assumed to observe the reference avatar is associated with the learner’s head motion. The virtual stereo camera is moved around the reference avatar away from the back of the avatar’s head in accordance with the head-rotating motion. As the HMAR was compared with two representative ordinary methods, i.e., a key-switched rearview (KSR) and a mouse-associated rearview (MAR), the elapsed time of the HMAR showed significantly smaller variance, although did not show any significant difference in the mean.
