The study aims to reveal the effect of in-air gesture interaction using the depth camera technology on complex human performance and to identify possible design failures and its implementation to the digital shadow play. Since in-air coordinate system of body kinematics shares the same directional vector with on-screen coordinate of the visual character, a systematic approach “directional vector transformation” has been proposed for transforming the in-air coordinate into the on-screen coordinate. A comprehensive literature review of human computer interaction, digital shadow play and gesture interfaces is given. Finally, identification of design failures and design guideline for further study are made for the design of in-air gesture interfaces.
