Dean's award for outstanding master thesis

This work is dedicated to designing a system for generating route descriptions for visually impaired people. Complete system for creating such descriptions is designed and implemented. Work starts by analyzing mobility and orientation capabilities of visually impaired people. Then it discusses, how can be a suitable source of map data used to create descriptions of urban areas for them. Complete algorithm for automatic generation of such descriptions is proposed. Solution includes schema for retrieving data from GIS data source, extracting essential information and creating naturally sounding route description with use of context of individual map elements. This algorithm supports customizing generated description according to end-user’s preferences which makes it very flexible and easily modifiable.
