A Model for Context-Specific Route Directions

Context-specific Route Directions

Today’s wayfinding assistance systems provide route directions that are significantly different to those generated by humans, resulting in a gap between what users expect and what the system delivers. This dissertation contributes to closing this gap by presenting a process that adapts instructions to environmental characteristics and a route’s properties, thereby implementing principles of hum...

Context-specific route directions: generation of cognitively motivated wayfinding instructions

Modeling Spatial Knowledge for Generating Verbal and Visual Route Directions

Challenges in the development of state-of-the-art navigation tools involve the synchronous generation of user-tailored natural language directions and accompanying graphical representations. Of particular interest is the combination of indoor and outdoor scenarios. We describe an architecture for simultaneously generating route directions and suitable visualizations of the navigational context ...

A Different Approach to Route Directions

Current wayfinding assistance systems calculate primarily two kinds of routes: the shortest or the fastest. To overcome this limitation, recent research extends options in route choice. All approaches, however, provide the same kind of information independent of the route at hand, i.e. all route directions are created the same way irrespective of the route's characteristics. In contrast, we wil...

Shortest, Fastest, -- but what Next? A Different Approach to Route Directions
