Abstract | Research in the domain of public displays has come a long way since the 1970s. This relatively new field is trying to overcome challenges that came up in finding a common ground for designing efficient techniques to get the most out of public displays. Attention grabbing and humancomputer interaction are very important topics and are difficult to implement in a satisfying way. Gaze-based approaches are widely used when it comes to solving those problems. However, accessibility and assistive features are still rarely incorporated when dealing with public displays. Visually impaired people in particular are mostly unaware of public displays and have very few means of approaching them and interacting with them. This thesis analyzes current problems visually impaired people have when dealing with public displays by interviewing them inside a focus group and by providing an online survey. Based on the gathered results a prototype was implemented simulating a public display environment. Users can interact with those public displays via their regular smartphones using a Bluetooth Low Energy connection. The application is running in the background and users get notifications when the public display is nearby. They get useful information at once and can query the public display for more information via the application on their smartphone without using the public display directly. A multi-user approach is used to support real-time communication through the public displays and to examine possible scenarios of interaction between users. Since this thesis focuses on accessible content, great attention is directed to give suggestions what kind of content is most suitable and how to appropriately make it accessible. Visually impaired participants test this prototype in a user study. An evaluation of all the data outlines important feedback and gives valuable design implications when dealing with accessible public displays for future research topics.
