WACL: supporting telecommunications using - wearable active camera with laser pointer

Abstract

We propose a wearable active camera with laser pointer(WACL) as a human interface device for use intelecommunications. The WACL laser pointer is attached tothe active camera-head and it can point a laser spot whileelevating and panning the camera-head. In our system, aremote instructor can observe around the worker, who iswearing the WACL, independently of the worker's motion,and can clearly and naturally instruct the worker in tasksby pointing the laser spot at real objects. This paperdescribes the outline of a telecommunication supportsystem using the WACL and a method to stabilize thecamera and laser pointer independently of the wearer'smotion. We have implemented and demonstrated anexample of an application using our system.
