The Advantages and Limitations of a Wearable Active Camera/Laser in Remote Collaboration

Abstract

The Wearable Active Camera/Laser (WACL) allows the remote experts not only to set their viewpoints into the wearers’ working place independent of their motion but also to point to real objects directly with the laser spot by controlling it through wireless network. In this paper, we examined how communication patterns differ between the WACL interface and a typical headset interface. The results have implications for improving the WACL interface so as to redress the communication asymmetries by enhancing the visual assist.
