Abstract: This paper uses the virtual reality (VR) technique in the design of office automation (OA) equipment teaching system, and analyzes the structure characteristics and advantages of Virtools and 3DS Max. Through the strong interactive function of Virtools platform within the multimedia classroom environment, this paper aims at the research and design of the office automation equipment teaching system in colleges, analyzes and solves the problems which are appeared in the process of system design, so as to complete the virtual display of the OA equipment and simulation of electricity usage finally. Then the feasibility and practicability of virtual reality technique could be seen in the use of instructional system development.

Key words: Virtools, interactive, virtual display, office automation equipment
