CLUE: A Usability Evaluation Checklist for Multimodal Video Game Field Studies with Children Who Are Blind

Multimodal video games can enhance the cognitive skills of children who are blind by allowing interaction with scenarios that would be unfeasible in their everyday life. To assist the identification of relevant interface and interaction issues when children who are blind are playing multimodal video games, we propose a Checklist for Usability Evaluation of Multimodal Games for Children who are Blind (CLUE). CLUE was designed to assist researchers and practitioners in usability evaluation field studies, addressing multiple aspects of gameplay and multimodality, including audio, graphics, and haptics. Overall, initial evidence indicates that the use of CLUE during user observation helps to raise a greater number of relevant usability issues than other methods such as interview and questionnaire. CLUE makes the analysis of recorded user interactions a less timeand effort-consuming process by guiding the identification of interaction patterns and usability issues.
