Mr. Addison Chan

B.Eng. (HKUST), M.Phil. (CityU)

About Me:

I received my Master of Philosophy in 2002 from the City University of Hong Kong, while my Bachelor degree in Computer Engineering was obtained in 1999 from the Hong Kong University of Science and Technology. I am now a PhD candidate in computer science at Durham University.

Research Interests:

Computer Graphics and Motion Prediction in Networked Virtual Environments (NVEs)

Past Experiences:

After I had earned my M.Phil. degree from City University of Hong Kong, I was involved in both industrial and academic area. Follows are the brief description of my profession history.

2002-2004: Senior Programmer --- The project on "Web-based 3D collaborative engine" (funded by PCCW, Sun Microsystems and ITC)

In this project, we developed a Web-based 3D collaborative engine. This engine was basically a set of tools that will support 3D collaboration and interaction over the internet. The engine included some of the techniques that we had developed. In particular, it includes methods for rendering and progressively transmitting flexible objects and for handling 3D interactions over the Internet.

2004-2005: Software Engineer --- The project on “Remote Emission Sensing on Road” (collaborated with Hong Kong Environmental Protection Department (EPD))

In this project,  a system was developed to analyse and show vehicle emissions on the road. The results captured and analysed by the system were used to investigate the air pollution level due to the vehicle emission in Hong Kong. The system is based on examining the spectrum produced by the plume whenever an vehicle passed by.

2005-2006: Senior R.A. --- Department of Computer Science, City University of Hong Kong

I devised to cope with the problem of network latency involved in NVEs, particularly those adopting the on-demand download approach (the environment models are streamed to the hosts via Internet). A method of predicting users' walking patterns were developed so that the latency could be reduced. Also, I worked on Collaborative Design Environments (CDEs), which applied Cyber Gloves as input devices. A prediction method on hand motions was created and it was useful in maintaining consistent states among users in the environments.
