Personas allow designers to build empathy towards users, avoiding reliance on stereotypes or assumptions. When it comes to creating personas for people with disabilities, a common procedure is to integrate impairments as dedicated characteristics. However, when considering Deaf and Hard of Hearing (DHH) individuals as target group, we argue that such an approach is incompatible with the latter's own ability-based identification concepts. Thus, we propose a modification of personas for DHH users by defining them in terms of ability ranges and driving or keeping factors within specific contexts. Starting with assumption personas based on previous research, we conducted focus groups with DHH individuals from which we derived the data and perspectives that formed our modification. With this approach, we want to promote an adequate representation of DHH users among designers while also demonstrating an application of Ability-Based Design to HCI methods.
