Construction of Experimental System SPIDAR-HS for Designing VR Guidelines Based on Physiological Behavior Measurement

摘要

VR technology is still under development and only the evaluation of the performance and functions of VR devices is being studied. There are few studies that are as subjective and difficult to evaluate as the study of immersion in VR. Moreover, methods and indicators for evaluating this characteristic are still unclear. By evaluating this characteristic quantitatively, it seems that technological development for enhancing the immersive feeling in the virtual space will be greatly improved. Therefore, the final goal of this research is to clarify the relationship between sensory display (force, vision and auditory sense) and Sense of Agency (SoA) in VR environment through physiological behavior measurement. To achieve the final goal, the aim for this paper is to establish a human-scale VR environment and to prepare an environment in which the SoA can be evaluated. We conducted physiological behavior measurements on two tasks, which are the "ball-catching task" which consists of dropping a ball weighing 220 g from a height of 80 cm and catching it, and the "rod-tracking task" that consists of moving the rod so as not to touch the wall of a sinusoidal path. In the "ball-catching task," it was possible to evaluate the strength of force sense, and the evaluation of the slight force sense was carried out based on the "rod-tracking task."
