TilePoP: Tile-type Pop-up Prop for Virtual Reality

Abstract

We present TilePoP, a new type of pneumatically-actuated interface deployed as foor tiles which dynamically pop up by infating into large shapes constructing proxy objects for whole-body interactions in Virtual Reality. TilePoP consists of a 2D array of stacked cube-shaped airbags designed with specifc folding structures, enabling each airbag to be infated into a physical proxy and then defated down back to its original tile shape when not in use. TilePoP is capable of providing haptic feedback for the whole body and can even support human body weight. Thus, it allows new interaction possibilities in VR. Herein, the design and implementation of TilePoP are described in detail along with demonstrations of its applications and the results of a preliminary user evaluation conducted to understand the users' experience with TilePoP.
