Abstract: Public restrooms are used by most people but for some, these visits are inconvenient, filled with worry or fears. In 2016, a comprehensive survey was conducted in which more than half of the responded believed that they could get a disease from public restrooms, more than a quarter avoided touching the door handles and 45% avoided visiting a public toilet due to lock issues (Toalettrapporten, 2016). In 2002, requirements regarding public restrooms were introduced in Sweden to promote accessibility for people with reduced mobility. These requirements include, among other things, wide doors, low thresholds, placement of actuators (Boverket, 2018). Despite these adjustments, the door is still an obstacle for some people, even if they are automated (Skoller, 2010). This master project examines the user experience for automated doors for accessible public restrooms in collaboration with ASSA ABLOY in Landskrona. The project aims to investigate how the user experience is influenced by the interface for automated doors and to develop a visionary concept based on the research results. As a starting point for the project, a prototype of an interface developed by ASSA ABLOY was investigated. To examine the user experience, a combination of methods was used: UX design, Humancentered design, inclusive design and design thinking process. The results of the research showed that the user experience was affected by three key factors: Hygiene, safety, accessibility. Regarding hygiene, it was found that the user wanted to avoid physical contact with both door handles and locks. Regarding security, it was important for the user to feel confident in the lock and that it could be used in the event of a power failure. With regard to accessibility, it was important that door and lock could be used regardless of functional impairment where range, precision and strength were some of the factors. Based on this research, a concept was developed for an interface that consists of door openers with touchless technology, indications with clear symbols, alarm function and an automatic lock that could be used manually.
