Hovering and Contact Representation of Laser Contour-Based Hand with Swinging Tablet PC for Distant Communication

ABSTRACT

As covid-19 spread worldwide, the growing trend to reduce people's mobility and the establishment of new lifestyles such as remote work, contactless communication systems have been required. Using a projected hand makes it possible to realize remote communication with a sense of presence without loading a user's physical body. However, conventional projected hand systems have a problem that the relative brightness of the hand image in a bright living room is low. Therefore, we propose a configuration that combines a video call system and a contour-based projected hand by a laser scanning projector. In addition, we incorporate a haptic feedback system with a tablet PC to improve the sense of contact with remote objects. To enhance the sense of contact in remote areas, we focus on providing the transition between hovering and contact states of the contour-based projected hand and users' hands. According to the experiment, we confirmed that there is a possibility to express hovering and contact even with simple swinging flat-panel feedback and visual effects of the contour-based projected hand. © 2022 Owner/Author.
