Abstract：Most current virtual experiments teaching systems are 2D interactive interfaces-based, which exist the shortcomings of abstract experimental results, single pattern of human-computer interaction and unintelligent in application，experimental results are not accurate; while the conventional 3D virtual experiment system are also faced with problems, that is, high soft development cost, poor render effect and the dependency on operation platform，does not have the very high interactivity. In order to solve the drawbacks above, combining the efficient game engine called Unity3D with augmented reality (AR) technology, a 3D virtual experiment system supporting AR human-computer interaction was designed, which took the electrical and electronic experiment of technological university as an example. The well designed 3D virtual experiment system has the characteristic of lifelike experimental environment, multiple patterns of human-computer interaction, intelligent error detection mechanism and cross-platform. Evaluating the main performance parameters, the well practicability was confirmed.?????
