In this study, a VR-based Doppler effect learning support system was developed. In a real space, it is too difficult for learners to control the position of a sound source and to change his/her position. Whereas, in a virtual environment, learners can control two objects easily. So we constructed a VR-based experimental environment to learn Doppler effect. To control objects in the virtual environment, a dual joystick controller is used. And, we proposed a velocity control approach. Using this approach, learners can control two objects’ velocities with the dual joystick controller. Additionally, using a head-mounted display (HMD), they can experience the difference in the sounds in various experimental conditions. From the evaluation of the developed system, it is confirmed that learners can easily control two objects in the virtual environment by using our proposed control approach. Moreover, from the results of learning verification, it is expected that learners can acquire the knowledge of Doppler effect through various experiences in the virtual environment by the developed system.
