Abstract
Operational transformation (OT) is a collaborative
computing technology for supporting advanced collaborative applications. OT
was originally invented for consistency maintenance and concurrency control
in collaborative editing of plain text documents in 80s. Two decades of
research has extended OT functionalities and applications to include group
undo, conflict resolution, operation notification and compression,
group-awareness, HTML/XML document editing, collaborative office productivity
tools, and collaborative computer-aided digital media design tools. Because
of its lock-free, unconstrained interaction control, and
consistency-preserving properties, OT is particularly suitable for supporting
real-time collaboration over the Internet. OT has recently been adopted as
the core collaboration technique in Google Wave, which is taking OT to a new
range of web-based applications and services, including e-mail, instant
messaging, blogging, wiki, and social networking.
The speaker has been working on OT research and application since 1994. In this talk, the speaker will share his experiences and lessons in researching OT issues, designing OT algorithms, and building OT-based collaborative applications, from 1-dimensional text editors (e.g. CoVim), 2-dimensional word processors (e.g. CoWord), to 3-dimensional computer-aided digital media design tools (e.g. CoMaya).

BIOGRAPHY
Dr Chengzheng Sun is a full professor in the School
of Computer Engineering at Nanyang Technological University (NTU) in
Singapore (http://www.ntu.edu.sg/home/czsun).
Since 1994, Dr Sun has been working on and making important contributions to
the theory, design, implementation and application of the operational
transformation technology. He has led and acted as the chief designer in a
number of well-known collaborative editing system projects, including REDUCE,
CoWord, CoPowerPoint, and CoMaya (http://cooffice.ntu.edu.sg). He has
published extensively in major international journals and conferences, and
delivered seminars and tutorials on operational transformation and
collaborative editing systems widely at major international conferences,
universities, and industry research labs.
Chengzheng Sun obtained a Ph.D in computer engineering from National University of Defense Technology, China in 1987, and a Ph.D in computer science from University of Amsterdam in 1992. From 1988 to 1993, he worked as a research scientist and a senior software engineer in University of Amsterdam, Philips Research Labs Eindhoven, and the ACE software company in The Netherlands, participated in a number of distributed system projects. From May 1993 to June 2005, he worked at Griffith University in Australia and became a full professor and Chair of Internet Computing in 1999. Since July 2005, he has been associated with NTU. His current research focuses on collaborative Internet computing, which lies at the intersections of Computer-Supported Cooperative Work, distributed systems, and human-computer interaction.

Abstract
The integration of virtual reality and computer aided design technologies is
a revolution in the history of design. Virtual environment provides more
information and feedback to designers than the traditional desktop system
can. Examples include immersive and stereoscopic visual information, haptic
or tactile feedback, auditory feedback and etc. The multimodal information is
in general rather intuitive and inspiring to the designers, resulting in
globally enhanced insights, creativity and productivity. Moreover, multimodal
virtual reality technology excels at the visualization of complex scene and
information, which is particularly difficult in desktop systems.
In this talk, we present our newest research attainments on 1. Online synthesis of multi-channel visual signal; the construction of multimodal virtual environment; 2. Fusion of graphic, image and video signals in augmented reality environment; 3. Synthesis of visual and haptic signals in virtual assembly; 4. Virtual design and simulation in the multimodal virtual environment, including surface deformation based on hand gesture interface, virtual assembly with haptic interaction, virtual maintenance in augmented environment; and 5. Demonstrations and Examples.
