Abstract
In order to realize realistic and smooth movement and work in a 3D virtual space, one of the major challenges is how to realize an interface that can effectively give a sense of agency to movement and work.
“Self-viewing”, which allows you to see your own body when you look at it in virtual space, is a very important factor for obtaining a sense of immersion. It is also considered to be a key point for obtaining a sense of agency. We are trying to build a unique interface that enables smooth movement in the virtual space by conducting experimental verification of the method and the main factors that give a sense of agency. We take up bicycle riding as a practical task in a 3D virtual space and we are developing an experimental interface which can provide a sense of agency during bicycle riding. The interface displays the avatar of the operator's hands and steering wheel synchronize with the steering of the bicycle in the field of view as an example of “self-viewing”. In this report, we describe an overview of the results of experiments on the correlation between avatar display methods, driver posture stability, driving control stability, sense of agency, etc. The results of a quantitative evaluation method for sense of agency, and further reports on the effectiveness of a subjective interface that utilizes such “self-viewing” are also described.
