Block, Florian, Wigdor, Daniel, Phillips, Brenda Caldwell, Horn, Michael S. and Shen, Chia (2012): FlowBlocks: a multi-touch ui for crowd interaction. In: Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 497-508. http://dx.doi.org/10.1145/2380116.2380178

Multi-touch technology lends itself to collaborative crowd interaction (CI). However, common tap-operated widgets are impractical for CI, since they are susceptible to accidental touches and interference from other users. We present a novel multi-touch interface called FlowBlocks in which every UI action is invoked through a small sequence of user actions: dragging parametric UI-Blocks, and dropping them over operational UI-Docks. The FlowBlocks approach is advantageous for CI because it a) makes accidental touches inconsequential; and b) introduces design parameters for mutual awareness, concurrent input, and conflict management. FlowBlocks was successfully used on the floor of a busy natural history museum. We present the complete design space and describe a year-long iterative design and evaluation process which employed the Rapid Iterative Test and Evaluation (RITE) method in a museum setting.
