Abstract
The final goal of this study is to elucidate the contribution of haptics and vision to the Sense of embodiment (SoE) in a virtual reality (VR) environment through physiological behavioral measurements. To achieve the objective, a rod-tracking task was employed in which a rod held in the hand is passed along a sinusoidal path in VR environment using HMD and haptic device. The problems identified in the previous system were the device positional accuracy and insufficiency of the force sensation. In order to solve these problems, the control circuit of the haptic device was modified. Then, the positional accuracy of the device and the force output characteristics of the device were evaluated. Through these evaluations, it was confirmed that the accuracy of the device was improved, and the strength of the force presentation was improved. In addition, we evaluated the experimental environment by measuring physiological behavior. The evaluation of the experimental environment by the physiological behavioral measurements was carried out by a questionnaire survey on the Rod Tracking Task, which included measurements of muscle potential and subjective evaluation. In the future, we will improve the accuracy of the device, improve the control circuit, and change the force-sensing model in consideration of the system construction.
