| Research Abstract |
(1) Pen-Based Drawing System for Geometric Design:
We proposed two novel interaction techniques called "interactive beautification" and "predictive drawing." Interactive beautification receives the user's free stroke input and generates multiple candidates by considering possible geometric constraints. Predictive drawing shows next drawing operation based on the spatial relationship among existing figures. We then developed a prototype system Pegasus, and achieved fast and flexible drawing interactions.
(2) Pen-Based Sketching Interface for 3D Freeform Design :
We developed a pen-based drawing system "Teddy", a sketching interface for creating 3D polygonal surface models. The user can create a 3D model by drawing 2D silhouette with a pen. Our informal user study showed that a first-time user typically masters the operations within 10 minutes, and can construct 3D models within minutes. This papers was awarded Impact Paper at SIGGRAPH'99.
(3) Context-aware information system for mobile computer :
We proposed a new information system architecture called the "WEBPAD system". WEBPAD is attempts to be a general-purpose context-aware UI system, which recognizes and predicts current user's "context" information. Our system employs thin-client technique to offload much of the data processing to the server. The server collects useful information from the WWW automatically. The user can create new information via a camera and a microphone, and the information is distributed to others via information filtering techniques.
(4) Multiple Painting Input System :
We developed a prototype system of multiple pointing input system. Our system recognizes multiple movements of devices that is moved by a user simultaneously, so the user can point and manipulate multiple object on the screen.
