Using Eye-Tracking and Emotion Recognition as Additional Sources of Information When Testing People with Intellectual Disabilities

Today, the development of special-purpose software for helping People with Intellectual Disabilities (PID) in their daily life and professional activities is a very active trend. Various testing systems with simplified text, images or videos are used to analyze problems, interests, and preferences of the PID related to their daily life or professional activities. However, in relation to the PID, the credibility of the test results might strongly depend on how much they understand the testing process and how they interpret questions and choose the answers.
