Research Projects

• Summer 2000 - present,    programming and research assistant,    New Media Department, IUPUI.

Working on the Distributed Virtual Concert Project, a collaborative virtual environement that enables musicians at geographically distributed sites to play MIDI music together through network. Musicians cohabit in a virtual concert room, telepresense is provided by avatars tracking the remote musicians, along with audio and video to help communication; music is generated from both local and remote MIDI messages. This project involves many disciplines such as virtual reality, virtual human, computer graphics, networking and distributed
system, artificial intelligence, computer music, acoustics, human factor study, etc; programming tools include C/C++, OpenGL, CAVE & CAVERNSoft, SGI MIDI lib, pthread, Internet2 etc.

• Spring 1999 - Fall 2000,    independent study,    Computer Science Department, IU.

Research on quaternion visualization, designed an interactive animation tool for interpolating 3D object positions and orientations, by interpolating both in the 3D geometry space and the quaternion space, implemented with C, OpenGL, GLUT, and CAVE.
 
• Spring and summer 1999,    independent study,    Computer Science Department, IU.

Research on database security, designed an extended model for mandatory access control using multilevel security labels and row constraints, implemented a prototype for this model using Oracle 8.

• Summer 1998,    Research Assistant,    Computer Science Department, IU.

Completed and improved the coding for a visualization tool called Emily for large sparse linear systems, using C++, Matlab and X-Motif. The tool was later integrated into the Linear System Analyzer as the Visual Component, using Java AWP.
 
• 1996 - 1997,    Research Assistant,    Distributed Systems Lab, Nanjing University, China.

Designed and implemented a Visual Programming Environment for Distributed Systems, using Visual J++, running on Windows95.
 
• 1995 - 1996,    Research Assistant,    Distributed Systems Lab, Nanjing University, China.

Participated in the project Intelligent Human-Computer Interface for Parallel Machine, implemented the module for natural language command processing, using Lisp, C++, and X-Motif, running on SUN Unix.
 
• Spring 1994,    Intern,    Tsinghua Computer Company, China.

Designed and implemented a Hypertext Documentation System used for product manuals, using Borland C++, running on Windows NT.
 
• Fall 1993,    Intern,    Dezhou Steelworks in Shandong, China.

Participated in a Real-Time Dynamic Control System for steel production pipeline, respoonsible for the design and implementation of the Dynamic Data Display module, using Borland C++, running on PC.

Experiences and Interests in IV

I'm very interested in virtual reality, which is my PhD research area for now. In relation with VR, I'm also interested in scientific visualization using virtual reality technology, especially applications in CAVE. Information visualization is relatively new to me, but I think the ideas and techniques in IV are closely related to scientific visualization. I've been working on a project called Virtual Concert (described above in section "Research Projects"), which is a collaborative distributed virtual environment, and which involves networking and maybe database techniques. There's a possibility that IV techniques might be helpful in such CVE systems. For example, visualization of the networking load in realtime might help the system to gain knowledge on the general patterns of networking communication and thus help decide how to optimize the data transfer to reduce delay and jitter, which are the crucial problems we are facing in CVEs.

From this course, I hope to learn some basic techniques in IV, improve my programming skills in Java 3D and Cave/OpenGL, Matlab, or any other graphics related development toolkits. Besides, I'm currently looking for a PhD thesis topic in the area of virtual reality or related areas, so I also hope this course can provide me a chance to do some intensive research in IV and hopefully find a topic that's related to VR that might lead to ta thesis subject.
