Development of Web-browser based thin-client low bandwidth workspace sharing system with real time display of remote mouse movement.

摘要

Desktop sharing is a key function in Internet conferencing solutions. There are many such software products available in this emerging market. The key players are WebEx, Microsoft (with NetMeeting), Citrix (with GotoMeeting), to name just a few. These commercial products allows remote users to view the same desktop as the host's, allowing remote presentation and training, remote technical support and troubleshooting, and so on. These commercial products are fully featured, enabling remote users to share the whole desktop content in real time. But the disadvantages are slow transmission and hefty cost, making it inconvenient for general purpose.; Due to the shortcomings of current products, such as high cost, complicated installation, slow remote desktop display, no true color capability, one-way sharing and security concern, there is a need to develop a better communication tool that can address these issues and meet the needs of certain user groups. I took the initiative to develop such an innovative system. This system, called Web-browser Based Thin-client Low Bandwidth Workspace Sharing System with Real Time Display of Remote Mouse Movement, is now widely used by Triton Global Sources, Inc., an Internet-based manufacturing outsourcing agent. It is highly commended by Triton's staff and its customers all over the country.; The thesis illustrates the technology in developing this system and a methodology to improve viewing comfort and effectiveness, utilizing JAVA Servlet/Tomcat, XML & DOM, VML, object-oriented JavaScript, etc. (Abstract shortened by UMI.)
