Abstract
While xR (including VR, AR, MR) technologies enable immersive and high-fidelity user experiences, there remains a lack of established methods for designing such experiences across multidimensional and voluminous information spaces. This paper proposes a verification methodology and a dedicated evaluation platform “Xperigrapher”, and design process with collaborative framework to propose international standards or guidelines for safe and efficient xR contents and applications by using this standardized common platform.

Abstract
The realism of experience of using a virtual body in virtual reality (VR) is associated with ownership (one’s self-attribution of a body) has been shown. However, whether or not ownership can be elicited for a virtual body presented by the third-person perspective is under debate. This study investigated the effect of multimodal presentations on the ownership of a male virtual body presented in the third-person perspective in three conditions (Visuo-tactile, visuo-motor, visuo-motor-tactile condition) (N = 40). We compared the illusory effect of ownership in the three conditions in male and female participants using a questionnaire and a 2 × 3 mixed-design ANOVA. Our study revealed that the male participants in the visuo-motor-tactile condition affirmed moderate (+1) of ownership, but the female participants did not. Ownership was significantly higher in the visuo-tactile (p < .01) and visuo-motor (p < .05) conditions. The results suggest that both visuo-motor synchrony and visuo-tactile feedback are essential factors to induce ownership to the virtual body in a third-person perspective. Moreover, our data suggest that matching the participant’s gender identity and the appearance of an avatar’s gender might be important for elicited ownership. Additionally, we evaluated the agency on the virtual body in the third-person perspective in the same three feedback conditions and found that only visuo-motor feedback is essential to elicit agency, unlike the causal factors of the ownership.

Abstract
Despite contributions to international standards for accessible information design for elderly and disabled persons, there still exists difficulty in addressing the specific needs of daily living contexts. In recent years, the application of virtual reality (VR) has been proposed to reproduce living scenarios in virtual spaces for behavior and training evaluation. This study proposed a no-code VR experimental platform which can evaluate human behavior and cognition in cyber physical society by reproducing experiences of various living scenarios by using a single comprehensive multimodal VR system. Furthermore, it is predicted that the COVID-19 pandemic will further raise the demand for cyber-social-lab research methods such as this platform that can simulate interaction with persons and things in virtual space in social situations requiring greatly reduced close-contact.
