An investigation on requirements for co-located group-work using multitouch-, pen-based- and tangible-interaction

Abstract

Cooperation and coordination is crucial to solve many of our everyday tasks. Even though many computerized tools exist, there is still a lack of effective tools that support co-located group work. There are promising technologies that can add to this, such as tabletop systems, multitouch, tangible and pen-based interaction. There also exist general requirements and principles that aim to support this kind of work. However these requirements are relatively vague and are not focused on concrete usage scenarios. In this study a user centered approach has been applied in order to develop a co-located group work system based on those general requirements but also on a real use case. The requirements are transformed into concepts and a running prototype that was evaluated with users. As a result not only the usability of the system has been proven but also a catalogue of even more specific requirements for co-located group work systems could be derived. © 2011 Springer-Verlag.
