Abstract:
While existing voice navigation systems provide simple and easy-to-understand directions, they have a disadvantage in that voice directions tend to be long when the number of left-right turns is large. The objective of this study is to realize a summarization method for voice directions that also provides a geographic image of the route to the destination. The system generates multiple candidate routes and simplifies the voice directions based on street names. Furthermore, we propose a method to evaluate multiple candidate routes and determine the optimal route using evaluation formulas that indicate the degree of summarization of both the route and text of directions. Experimental results showed that the proposed method yielded a higher route recall agreement rate in participants. Although the optimization method was effective, the evaluation formulas did not work well for some paths.
