The Wearable Active Camera/Laser (WACL) allows the remote collaborators not only to set their viewpoints into the wearer’s workplace independent of the wearer’s motion but also to point to real objects directly with the laser spot. In this paper, we report an user test to examine the advantages and limitations of the WACL interface in remote collaboration by comparing a head-mounted display and a headmounted camera-based headset interface. Results show that the WACL gives better impressions on comfortability when wearing, eye-friendliness, and fatigue in spite of no significant difference in task completion time. We first review related works and user studies with wearable collaborative systems, and then describe the details on the user test.
