THE EFFECT OF SPATIAL CUES IN AUGMENTED REALITY VIDEO CONFERENCING
Hirokazu Kato, Mark Billinghurst, Kentaro Morinaga, Keihachiro Tachibana · 2001
In this paper we introduce an Augmented Reality video conferencing system and show some results of the evaluation. The AR user can see remote users on paper cards in real world. The user can freely put virtual monitors. Then they can use spatial cues to get the communication smoothly. Also we appended a new function that eliminates background scene of desktop users. Evaluation results showed that video images play a important role for both AR and desktop users even if HMD occludes AR user’s eyes. Desktop user could identify the conversation relationship from AR user’s face angle. Also we expected that the elimination of background scene increases co-presence, but we could not confirm that from the experiments.
