3510.1 - Indoor Semantic Wayfinding

Currently, semantic-enriched navigation systems become more and more popular. Instead of providing metric-based route instructions such as "walk straight in 100 meters", semantic-based navigation systems provide users with semantic-enriched instructions, such as "walk straight, pass the theatre, and walk to the crossing" or simply "cross the park". This kind of guidance is more natural to users, and can improve users' navigation performances. However, current literature only addresses semantic wayfinding for outdoor environment, while the applications in indoor environment have not been approached.

This paper presents an on-going research project towards this direction. Particularly, the project aims at answering some fundamental questions of indoor semantic wayfinding , such as "what is an indoor landmark?", "what are the direction and motion concepts used in indoor naivgation?", and "how can semantic-enriched route instructions be automatically generated?". To answer these questions, empirical studies with human wayfinders in different environments will be implemented to study how they perceive indoor environments, as well as how they communicate route information. These route descriptions will be used to derive motion (verbs, e.g., "walk", "cross"), direction (prepositions, e.g., "straight", "along", "cross"), and landmark (nouns, e.g., "WC", "lift") concepts. These linguistic elements will be building blocks for semantic-enriched route instructions. As a next step, this project will investigate how these concepts can be computationally extracted from indoor data models, such as indoor GML.

Results regarding the empirical studies and the derivation of motion, direction and landmark concepts will be available in the next several months, and will be presented at the conference.
