Evaluating Effects of Hand Pointing by an Image-based Avatar of a Navigation System

[Abstract]

We investigate whether the behavior of pointing at a map by an image-based avatar helps a user understand a route in an image-based avatar navigation system. We also evaluate whether this behavior is preferred by the user. Existing avatar-based methods inform the user of a route by this behavior while talking. However, the existing methods do not consider how to incorporate a map. Thus, we consider how to inform the user of a route using an image-based avatar that indicates the route by pointing at a map. In the experiments, after users interacted with the system, we conducted a route depiction test to determine whether a user was able to correctly understand the route on a map and performed a questionnaire-based subjective assessment to determine whether the user liked the image-based avatar system. The results of the experiments show that the pointing behavior significantly increased the likeability of the system but did not help the user understand the route.
