Touch and Tangibles - Interacting with fun.tast.tisch. Results of a Study with Non-Target-Group Users

fun.tast.tisch. is an interactive tabletop system used in neurorehabilitation. It consists of several exercises to be interacted with by therapists and patients collaboratively. The user interface combines different interaction paradigms and tangible objects to facilitate therapeutic concepts. The acceptance of the system and its user interface relies on therapeutic aspects but also on straightforward interaction, usability and a positive user experience. A study with nontarget-group users was conducted, first, because earlier studies revealed that the target groups are not fully impartial regarding perceived usability/user experience. Second, interaction combining a touch-based interface with tangible elements and system feedback on different sensory channels involves usability/UX challenges that should be investigated in a non-critical situation. This paper describes selected fun.tast.tisch. modules, especially those involving tangible objects and summarizes the results of a related study.
