We present a system for collaborative conceptual design that allows users potentially located in geographically distant areas to cooperate by sketching, exploring and modifying the...
This paper presents an application framework for constructing sketch-based cooperative design (especially for distributed conceptual design) tools. Three key issues are addressed: ...
Abstract. We present a prototype sketch-based physics tutoring system that combines mathematical sketching, an interaction paradigm that supports construction of dynamic illustrati...
We present a system for creating and manipulating layered procedural surface editing operations, which is motivated by the limited support for iterative design in free-form modeli...
This paper presents a customizable system used to develop a collaborative multi-user problem solving game. It addresses the increasing demand for appealing informal learning experi...
