Somewhat Strange Feeling of Touching, Lifting, and Swinging in Mixed-Reality Space - Psychophysical Analysis of Haptic Illusion Caused by Visual Superimposition -

Mixed Reality (MR) is technology that can combine the real world and virtual world in real time. It realizes an interactive operation with real objects and virtual objects. In MR space, the appearance of a real object can be changed by superimposing a virtual object. It is possible to create different situations between haptic and visual information by utilizing the features of MR. The theme of the author's research is the examination of how human perception is changed by visual influences, and analysis of the conditions under which change occurs. Until now, it has been confirmed that the weight perception and volume perception are changed by superimposing virtual liquid objects over the real objects to alter liquid movement or liquid volume. This paper outlines current research and prospects.
