Many games suffer from accessibility problems such as lacking captions or being able to use specialized input devices which makes them accessible to a larg part of our population. An estimated 38 million people in the U.S. (14.3% of the population) are suffering from visual, auditory, cognitive or physical limitations. To improve current game design we can look at existing games and try to capture and describe elements of good game design with regard to accessibility. Many accessibility problems are also usability problems: for example playing a game without captions is an accessibility problem for an auditory disabled person but a usability problem for someone playing in a noisy environment. Motivated by this observation we explored how accessibility requirement can be described by existing usability solutions.
