Abstract:

In a virtual campus system, humanized humancomputer interaction design can make users receive lots of useful information. By the way，it can improve system availability and userfriendliness. The system displays the virtual campus, and supplies a virtual human which can be controlled by users, which makes users understand campus as real as possible. In order to let the users have better online interactive experience when they browse through the virtual campus，it puts forward and realizes several main interactive functions in the system，such as the interactive design about the control of a human and his view, the linking among different scenes, the linking of information, the tips and the virtual objects. This system also adopts multiscene design methods and uses VSL（Virtools Scripting Language）to design more complex interactive functions. These methods can enhance the program reusability and maintainability; reduce the system memory space occupied and improve the operation speed; implement some senior functions which cannot be achieved using Virtools builtin BB（Building Blocks）.
