3D Tabletop User Interface Using Virtual Elastic Objects

Hiroaki Tateyama, Takumi Kusano, Takashi Komuro

We propose a method to reduce the inconsistency between virtual and real spaces in manipulating 3D virtual objects with users’ fingers. By elasticizing a virtual object, our system prevents users’ fingers from thrusting into the virtual object and enables 3D interaction with a greater sense of reality.
