Evaluation of Gesture-Command Input Method for Pen-based Group KJ System

The processes involved in carrying out collaborative creative work and the ability to record and circulate the results are important. Previously, we proposed a label-capturing system for the group KJ method that uses anoto-based pens. The system instantly digitizes the positions and contents of labels containing ideas and thoughts, and then generates KJ diagrams for distribution. We also proposed a method for editing the visual properties of KJ diagrams using pen-writing gestures with physical transparent sheets on target labels. However, when the number of functions increases, the management of the physical transparent sheet becomes difficult. In this study, we verified the suitability of the system by introducing a user-defined gesture command framework. This framework increases the flexibility of user operation as well as the number of functions acceptable by the system. We confirmed the suitability through preliminary evaluation of the system with respect to recognition.
