Comparing human robot interaction scenarios using live and video based methods: towards a novel methodological approach

Abstract

This paper presents results of a pilot study that investigated whether people’s perceptions from live and video HRI trials were comparable. Subjects participated in a live HRI trial and videotaped HRI trials in which the scenario for both trials was identical, and involved a robot fetching an object using different approach directions. Results of the trials indicated moderate to high levels of agreement for subjects’ preferences, and opinions for both the live and video based HRI trials. This methodology is in its infancy and should not be seen as a replacement for live trials. However, our results indicate that for certain HRI scenarios videotaped trials do have potential as a technique for prototyping, testing, developing HRI scenarios, and testing methodologies for use in definitive live trials.
