Amazing forearm as an innovative interaction device and data storage on tabletop display

Abstract

In this study, we propose interaction techniques that use the forearm on tabletop displays positively. We define the forearm as the part of the arm between the elbow and the hand. On direct input surfaces, users' forearms often create problems such as incorrect recognition and occlusions. Therefore, the forearm is often considered problematic. Conversely, we think it could be possible to use it to create new interaction techniques. We propose new interaction on tabletop displays that use the forearm. In this paper, we describe how users can manipulate menu and data storages by these techniques. Our study offers new possibilities for using the problematic forearm in tabletop displays.
