Facilitating shared understanding of work situations using a tangible tabletop interface

Abstract

As work is an inherently cooperative phenomenon, it requires a common understanding of the nature of collaboration for all involved parties. In this way, explicit articulation work becomes an integral and essential part of collaboration. Implicit aspects of collaboration have impact on the quality of work results, mainly through social norms and observations of working together. Eliciting those aspects interactively helps in avoiding (mutual) misrepresentations and lack of understanding. Tangible articulation support systems allow aligning mental models of how work should be carried out. Stakeholders can develop a common understanding of collaboration in a semantically open and non-intrusive way. They are not burdened by explication features and diagrammatic notations. We have utilised experiences with model-centred learning theory to support explicit articulation work. According to our field studies, the resulting models can be fed back to current work practices and help in preventing problematic work situations.
