Abstract
Route planning applications are digital companions of many travelers, enabling them to experience different locations in a self-determined way. This work surveys the variety of commercial applications and research prototypes for itinerary planning with the goal of evaluating the interactivity aspect of these tools. For this purpose a framework to classify the interaction mechanisms and usage features of route planning pplications has been developed that differentiates between the point-of-interest and the aggregate tour layer. This proposed framework is applied to classify existing apps and points to opportunities for further research.
