Integrating Traditional Input Devices to Support Rapid Ideation in an Augmented-reality-based Brainstorming

Augmented reality(AR) has the potential to address the limitations of in-person brainstorming, such as digitization and remote collaboration while preserving the spatial relationship between participants and their environments. However, current AR input methods are not sufficient for supporting rapid ideation compared to nondigital tools used in brainstorming: pen, paper, sticky notes, and whiteboards. To help users create comprehensible notes rapidly for AR-based collaborative brainstorming, we developed IdeaSpace, a system that allows users to use traditional tools like pens and sticky notes. We evaluated this input method through a user study (N=22) to assess the efficiency, usability, and comprehensibility of the approach. Our evaluation indicates that IdeaSpace input method outperforms the baseline method in all metrics.
