Abstract:
The "ADAPEI Transport" app is an urban navigation tool for young people (10 to 20 years old) with intellectual disabilities. These disabilities lead to memory, time, and space perception problems. Using this tool, these young people learn how to use public transport and navigate in the city independently thanks to a reference path created by an educator. Along the path, steps are recorded to help the user interact with his/her environment in the navigation part. Currently, we are in the test and evaluation phase of the project for the navigation part. The aim of this article is to show the evaluation methods we have created (Python tool and questionnaire) to have feedback from real tests and to test the efficiency of the app. In fact, the app collects data from Inertial Measurement Unit (IMU) sensors and Global Positioning System (GPS), allowing to replay the journey done in a real test. The first results using the app in a real situation with a disabled youth and an educator are very encouraging. Additionally, thanks to the questionnaire and the Python tools developed to qualitatively evaluate a journey from user input, we were able to improve the app.
