What key design features can be identified in creating a tool/game for helping children open up about sexual abuse through the collaboration with health care professionals? In today’s society, sexual abuse of children is a real and common occurrence. This research will explore what role interactive media can play in helping children open up about abuse as well as identify 11 key design features for designing such a tool. To do so, the participatory method (Simon 2010) will be utilized throughout the design process, based on the collaboration with health care professionals to ensure as relevant and applicable design features as possible. The result of this study are the first iterations of designing this tool as well as the 11 key features that were identified with the help of health care professionals’ expertise.
