This paper presents the development and evaluation of an active video game in order to enhance reaction time of tennis athletes. The paper focuses on the perspective of the athletes and investigates the hypothesis whether or not they can get an improvement by practicing with that. Another goal of this paper was to investigate the difference between expert and inexperienced athletes in terms of general usability, usefulness, and user interface satisfaction. Overall, athletes were to a large extent satisfied with their gaming experience, rating the game as, easy to understand and learn and very satisfying.
