Lifelike animated agents for knowledge based learning en vironments can provide timely customized advice to support leaners problem solving activities By drawing on a rich repertoire of emotive behaviors to exhibit contextually appropriate facial expressions and emo tive gestures these agents could exploit the visual channel to more ef fectively communicate with learners To address these issues...

To many people, the word “multimedia” simply means the combination of various forms of information: text, speech, music, images, graphics and video. What is often overlooked is the interaction among these forms. In this paper, we will present our recent results in exploiting the audio-visual interaction that is very significant in multimedia communication. The applications include lip synchroni...

We present a visual specification language for constructing distributed applications and their direct manipulation graphical user interfaces. Each distributed application consists of a collection of independent modules and a configuration of logical connections that define communication among the data interfaces of the modules. Our specification language uses a single visual mechanism that allo...

The proliferation of data is threatening to swamp our ability to convert data into knowledge. Visualization promises to facilitate this conversion. Yet visual communication designers have not been deeply involved. One potential impediment to involvement is the lack of collaboration between visual communication designers and knowledge workers in specialized domains This paper describes a collabo...

Cooperative visual modeling is more and more necessary in our complicated world. A collaborative environment which supports interactive operation and communication is required to increase work efficiency. We present a collaborative visual modeling framework which collaborative platform could be built on. On this platform, cooperation and communication is available for designers from different r...
