With 3D virtual reality (VR) technology and game design developing rapidly, a growing number of research experts are becoming involved in the study of motion sensor interactions and VR headset devices. At present, headset devices easily cost up to hundreds or even thousands of dollars. As a general gaming accessory, the price point of these devices is quite high. To reduce the cost of gaming accessories, this study combined the most current and popular headset device, with motion sensor and 3D VR technology to develop a lowcost 3D interactive VR system. This system utilized Homido VR headset to carry a smartphone, and Leap Motion, the motion sensor, was used to track hand gesture changes. Unity was used as the main 3D VR developmental environment to develop a 3D dart game system. To portray a realistic 3D environment, this system utilized Unity to develop the headset’s side-by-side (SBS) 3D image for the left and right eyes. The SBS image for the left and right eyes was presented via the Homido VR headset equipped with the smartphone, allowing the user to gain a more immersive experience of the 3D dart game environment. The experiment results showed that while this system displayed SBS 3D game content to the users, they could use Leap Motion to manipulate 3D virtual objects instantaneously. Thus, this system presents users with 3D real-time interactive experience via the head-mounted
