Use of GPS Tracking to Interactively Explore Disabled Children’s Mobility and Accessibility Patterns

Abstract

This paper presents a methodology that addresses the need to assess disabled children’s mobility and access in the context of the built environment. A novel combination of automated Global Positioning System tracking technologies, visualization using time diaries and 3-D maps, and interactive interviewing with disabled children is used to explore the real-world accessibility issues these children face. Pilot test results are used to illustrate the multi-stage method of data collection, a summary of results, and methodological challenges. Future studies should capitalize on automated activity tracking to minimize the need for participant recall and maximize the time spent engaging participants in discussion of pertinent issues.
