Accessible Question Types on a Touch-Screen Device: The Case of a Mobile Game App for Blind People

This study investigates accessibility and usability via screen reader and gestures on touch-screen mobile devices. We specifically focus on interactive tasks performed to complete exercises, answer questionnaires or quizzes. These tools are frequently exploited for evaluation tests or in serious games. Single-choice, multiple-choice and matching questions may create difficulties when using gestures and screen readers to interact on a mobile device.
