In our daily life, human beings tend to use both hands to accomplish complex tasks, but not to computers. However, multi-touch technology allows users to control all objects on the screen with more than just one linger. Therefore, how designers can take advantage of such technology and explore its potentials? So we propose a multi-touch interface builder called MToolKit for easy and effective construction of multi-touch interface for designers. By using camera-based sensor framework, we further analyze the multi-touch examples available for the interactive patterns. With these analysis and design requirement for building up an interface builder for designers, we conduct a two-point input and implemented them into our system called MToolkit. MToolkit was implemented by java and based on processing programming environment and a video processing C++ library with java wrapper. An example of using our MToolkit is elaborated in this paper.

Design is an interactive endeavor involving the evolution of ideas between two or more participants in discussion, especially during the conceptual design stage. Idea association is an important behavior for generating diverse ideas through the dynamic exchange of varied knowledge possessed by the participants. To better understand the dynamics that take place, this research applies a cognitive theory (role playing) that models the distributed interactions. BY using the Dynamic Agent Role Interplay System (DARIS), some computational components within the distributed interactions are computed and evaluated. Finally, a distributed linking model named Dynamic Idea Maps II (DIM-2) is computerized to support the idea association in a distributed collaboration environment. The computational mechanism it will be elaborated by means of a design experiment. (c) 2006 Elsevier Ltd. All rights reserved.
