This paper presents a design, implementation, and evaluation of an augmented reality virtual environment to support collaborative brainstorming sessions. We specifically support brainstorming in the form of ideation on sticky notes, a common method to organize a large number of ideas in space with sticky notes on a board. Our environment allows users to integrate physical pen and paper used in a brainstorming session with the support of augmented reality headsets, so that we can support further interaction modes and remote collaboration as well. We use an AR HMD to capture images containing notes, detect and crop them with a remote server, then spawn the detected notes in to enable virtual viewing and manipulation. We evaluate our input method for generating notes in a user study In doing so, we attempt to determine whether traditional input tools like pen and paper can be seamlessly integrated into augmented reality, and see if these tools improve efficiency and comprehensibility over previous augmented reality input methods.
General Audience Abstract
Collaborative brainstorming sessions often involve rapid ideation and outputting those ideas on physical sticky notes with others. We built a virtual environment, IdeaSpace, to support collaborative brainstorming in augmented reality head-mounted devices. To support the activities of rapid ideation and creating notes to express those ideas, we developed an input method for creating virtual note objects for augmented reality collaborative brain-storming sessions. We allow users to use traditional tools like pens and sticky notes to write out their notes, then scan them in using device cameras by uttering a voice command. We evaluated this input method to determine the advantages and disadvantages it brings to rapid ideation in augmented reality, and how it affects comprehensibility compared to existing gesture-based input methods in augmented reality. We found that our pen and paper input method outperformed our own baseline gesture input method in efficiency, comfort, usability, and comprehensibility when creating virtual notes. While we cannot conclude that our experiment proved that pen and paper is outright better than all gesture-based input methods, we can safely say pen and paper can be a valuable input method in augmented reality brainstorming for creating notes.
