Architecture and prototype of augmented Reality videophone service

A system architecture that enhances existing videophone service with Augmented Reality (AR) technology is designed. The architecture is used to prototype an “AiR Stamp” system that allows users to place virtual objects on video images as if they were affixing stamps to actual scenes. System feasibility is evaluated by applying it to a remote support service scenario where the stamps are used for telepointing. The video latency and accuracy of stamp positions are confirmed to be at a usable level.
