This paper introduces a practical and cross-platform virtual electrical experimental tool (VEET) based on an off the shelf game engine called Unity3D which is powerful and flexible to develop Virtual and Augmented Reality (VR/AR) applications. Taking the electrical experiments of technological university as examples, the well designed virtual experimental system has the characteristics of lifelike three dimensional (3D) experimental environments, AR interactive interface on mobile devices, intelligent detecting mechanism and cross-platform. We described VEET’?s flexible design and demonstrate its use in teaching where 120 students from three classes conducted electrical experiments with it. The experiments in VEET were presented on desktop, mobile and web browser using low cost common devices (personal computer, android handheld device, Chrome browser). Evaluating the main performance parameters, the well practicability was confirmed. |
