: This paper presents a virtual reality application dedicated to electronics virtual experiments: circuit design and simulation. The virtual environment offers virtual components (resistors, capacitors and transistors) and virtual electronics equipments (generators and oscilloscopes) described in a standard Virtual Reality Modeling Language (VRML) format. Students can choose components and build a circuit. A remote simulation of the circuit is achieved using the SPICE program that is a general-purpose circuit simulation program for non-linear dc, non-linear transient, and linear ac analyses. Simulation results are displayed on virtual electronics equipments that are involved into the simulation. The implementation is based on VRML and Java as languages and Cortona VRML plug-in from ParallelGraphics. It is available on the Internet at the following URL:
