Abstract

IllusionHole (IH) is an interactive stereoscopic tabletop display that allows multiple users to interactively observe and directly point at a particular position of a stereoscopic object in a shared workspace. We explored a mid-air direct multi-finger interaction technique to efficiently perform fundamental object manipulations for single user (e.g., selection, rotation, translation and scaling) on IH. Performance of the proposed technique was compared with a cursor-based single pointing technique by a 3D docking task. The results showed that direct object manipulation with proposed technique provides greater benefits on user experience in a collaborative environment.
