Easing the integration: A feasible indoor wayfinding system for cognitive impaired people

People with cognitive disabilities have to acquire several skills in order to achieve autonomy and self-development. One of these is indoor navigation through new and complex environments such as their school or work center. We propose a smartphone application that helps them to get from one place to any other in a modeled environment, following a trail of clues. It is based on location through QR codes, which makes it inexpensive, straightforward to implement and reusable. We conducted an experiment on 14 users with several cognitive disabilities in an unfamiliar environment. The results validated both the system and the approach.
