| Research Abstract |
The purpose of this research is to support, drawing diagrams in the upper stages of creative activities by using computers. We aimed at developing an interactive system with the following features to realize both functional support with the computer and consideration to the aspect of the feelings and impressions. (1) The main processing objects of the tool are diagrams with logical structures. (2) The tool provides a freehand sketching interface. (3) The tool maintains the feel and ambiguity of drawing done by hand. (4) The tool supports drawing intellectually and actively. We developed fundamental techniques for freehand drawing environments and creative activity supporting environments. Furthermore, we performed the development of the application program as a freehand drawing environment. We thought that looking back was important on creative activities, so we considered operations of logical structures of diagrams with historical data, and then developed a tool with such the operations. We also thought that it was important that computers offered flexible input interface as a freehand input interface. Therefore we developed a note pad tool which took freehand strokes as input data and gesture commands. Furthermore, we developed a stylus installed accelerometers because it is not necessarily easy to use the ordinal stylus which spread as an input device for freehand drawings. The new style of stylus enables us to use hand motions in the air for interactions with computers. As an application program of some fundamental techniques we developed an electronic whiteboard system. Writing on the blackboard in the classroom is one of the important scenes of creative activities, We developed an environment that supported reuse of writing on the blackboard.
