Gaze control is a substitution for disabled people to play computer games. However, many disabled people may be inexperienced in games and/or novices using gaze-control. This study presents a game accessibility approach using gaze control modality for novice players and disabled people. A workshop was conducted involving a playtest on three games with gaze-control. The game experiences were observed, recorded, and evaluated with mixed methods. The study estimated the gaze control game accessibility by System Usability Scale (SUS), Game Experience Questionnaire (GEQ), and an open-ended questionnaire. The gaze control modality demonstrated possible game accessibility to people with motor disabilities. The results also indicate that the challenge of game mechanics and the accuracy of the gaze-control system are two significant impact factors. Further research will be conducted on gaze-control games including more disabled people, and also develop the data analysis methods for evaluating gaze-control modality for game accessibility.
