Editing the Visual Properties of Collaborative KJ Diagram Decoration by User-Defined Handwritten Gestures

The process of collaborative creative work and the ability to record and circulate the results are important. Previously, we had proposed a label capturing system for the group KJ method that uses Anoto-based pens. The system instantly digitizes the position and content of each label containing ideas and thoughts, and then it generates KJ diagrams for distribution. The users can also edit the visual properties of the KJ diagrams by writing gestures with their pens on target labels. However, the system could only accept pre-defined gestures, and the users could not register their own patterns. In order to eliminate these restrictions, we introduce a mechanism to register user-defined gesture commands. After users register their original gestures, they can change the appearance of labels with their favorite pen movements. By applying the mechanism to our group KJ system, the user´s experience and understanding of the system are improved.
