Key Points
We use a navigation system in which an image-based avatar points at a map to explain a route. Route depiction tests and subjective assessments separately examine the effects of pointing on route understanding and users' liking of the system.
Abstract
Does pointing at a map make directions easier to understand? Does it also make people like the guide more? We studied these two questions separately using an image-based avatar, an on-screen guide made from video of a real person.
We developed a navigation system in which the avatar points at a map while explaining a route. After receiving the guidance, participants drew the route on a map to show what they had understood. They also completed a questionnaire about how much they liked the system. This allowed us to evaluate both route understanding and the impression of the guide.
Pointing improved how much participants liked the system, and statistical analysis supported this difference. However, it did not help participants understand the route correctly. The results show why making guidance more appealing and making its content easier to understand need to be assessed separately.
