Abstract

In this poster, we present an experiment that compares three forms of interaction to study the user behavior with regards to the effects of camera view for in-situ robot control. We compared three hand-held interfaces with: (1) no camera view (Nominal), (2) a camera view/aim is always fixed toward the robot (Fixed) and (3) a camera view with user controlled aim (Free). The three approaches represent different balances between information availability, interface accessibility and the amount of induced attentional shifts. Experiment results have shown that all three interaction models exhibited similar task performance even though the Fixed type induced much less attentional shifts. On the other hand, the users much preferred the Nominal and Free type. Users mostly ignored the camera view despite having to shift one's attention excessively, due to the lack of visual quality, realistic scale and depth information.
