An evaluation of conversational interfaces for pedestrian navigation : a thesis presented in partial fulfilment of the requirements for the degree of Master of Information Technology, Institute of Natural and Mathematical Sciences, Massey University, Albany, New Zealand
The aim of this research was to compare the performance between the OsmAnd
application and three types of conversational interface, to test whether the conversational
interface is a more preferred navigation tool. We designed and tested four different navigation
systems; the map with command interface, the conversational-only interface, the
conversational with map interface, and the conversational with image interface. The research
involved 100 participants who had different levels of experience when using navigation
systems. Participants were divided into three groups and were given different navigation
interfaces. This research was conducted with both quantitative and qualitative usability testing
along a pre-defined route in Massey University campus, combined with a USE questionnaire
to gain the user’s feedback. The results indicated that both the OsmAnd and the conversational
interface were good in different criteria. However, most participants preferred using the
conversational interface more than the visual interface.
