AffinityTable : a hybrid surface for supporting affinity diagramming

2011, Geyer, Florian, Pfeil, Ulrike, Budzinski, Jochen, Höchtl, Anita, Reiterer, Harald

Using affinity diagramming as an example, we investigate interaction techniques for supporting collaborative design activities. Based on an observational study, we identified design guidelines that need to be addressed to find a close fit to embodied practice. Using this knowledge, we designed and implemented AffinityTable, a hybrid surface for supporting affinity diagramming. The tool combines digital pen & paper with an interactive table and tangible tokens. An additional vertical display is used to support reflection and group coordination.

Designing reality-based interfaces for creative group work

2011, Geyer, Florian, Pfeil, Ulrike, Höchtl, Anita, Budzinski, Jochen, Reiterer, Harald

Using affinity diagramming as an example, we investigate reality-based interfaces for supporting creative group work. Based on an observational study grounded in the reality-based interaction framework, we identified power vs. reality tradeoffs that can be addressed to find a close fit to embodied practice. Using this knowledge, we designed and implemented a digital workspace for supporting affinity diagramming. Its hybrid interaction techniques combine digital pen & paper with an interactive table and tangible tokens. An additional vertical display is used to support reflection-in-action and for enhancing discussion and coordination. A preliminary user study confirmed the applicability of our tradeoffs and the general acceptance of the tool design.
