Universal Design of User Interfaces in Self-driving Cars

Self-driving cars are already being tested in our roads, and several benefits to society are expected with their mainstream use. They also present an opportunity to increase independent mobility for people with disabilities and the elderly. To achieve this, however, the in-car interaction should be redesigned to be suitable for these groups of previously excluded car users. An investigation of existing literature helped us identify two main challenges that could impact the adoption of self-driving cars by such users, namely, their acceptance and multimodal in-car interaction. To mitigate such challenges, we propose in this paper a model that frames the process of universally designing the in-car interactions to increase usability for everyone, while maintaining safety. We argue that integrating universal design early in the development of in-car interaction will ensure their accessibility and usability by all people.
