| Abstract(in English) | An HMD user is likely to feel isolated when sharing VR experiences with Non-HMD users due to not being able to see the real space outside the virtual world. This research proposes a method for an HMD user to recognize the Non-HMD users’ gaze via a projector attached to the HMD. The projected HMD user’s view is filtered darker than default, and when Non-HMD users point controllers towards the projected view, the filter is removed from a circular area for both users indicating which region the Non-HMD users’ are viewing. We conducted two user studies showing that the Non-HMD users’ gaze can be recognized with the proposed method, and investigated the preferred range for the alpha value and the size of the area for removing the filter for the HMD user. |
