Evaluating the Effectiveness of Design Guidelines in an Indoor Navigation App for People With Disabilities

This study evaluated the application of indoor navigation design guidelines for individuals with disabilities using a custom-developed app, FIND, as a testbed. Twenty-five participants with or without disabilities completed five use-case scenarios while performance data and qualitative feedback were collected. Results supported several key guidelines related to consistency, user control, and real-world alignment, while also identifying areas for improvement. The findings of this study, in terms of guidelines, can be used by developers and researchers when designing indoor navigation technologies to better cater to the diverse needs of individuals with disabilities.
