Usability Guidelines for Co-Located Multi-User Interaction on Wall Displays
Andrea Nutsi · 2015
Today interactive wall displays can be widely seen in industry and research. Due to their size, these displays offer the opportunity for several users to interact co-located and simultaneously. An application supporting multi-user interaction has to be designed differently than traditional single-user interfaces, for example supporting several parallel workspaces or considering by-standers. The overall goal of this thesis is the development of usability guidelines for multi-user applications running on interactive wall displays. These guidelines should aid developers of future applications in ensuring a high multi-user usability. The research approach combines literature analysis with usability studies and controlled laboratory studies. The literature analysis and the usability study will identify aspects specific to multi-user usability. The laboratory studies will deepen the understanding of two selected usability aspects, with readability in a multi-user scenario being one of them.
