Tablaction: Collaborative brainstorming system with stylus-fingertip interactions on tablet PCs

Abstract

In this paper, we introduce the Tablaction that supports collaborative brainstorming process by unifying various interactions utilize stylus and multi-touch finger input. Additionally, we demonstrate the specially designed stylus for it, and the paper prototype test. In a brainstorming meeting, there is a problem that everyone cannot equally participate in the brainstorming. There were several approaches to this problem; however, their interaction styles were limited to the devices. Tablet devices with multi-touch capability are commercialized fast in these days. In addition, the researches on pressure recognition to replace the touch panel are actively on progress. With the technologies, the tablets would be capable to recognize a stylus, and distinguishing it with a fingertip. We expect that the interaction design with the capability will accelerate idea expressions in a brainstorming meeting.
