We developed a running support system using body movements as input in a realistic 3D Map. The users use their body movements to control movements in the 3D map. We used depth-camera sensor to track the user’s body joints movement as the user moves. The location changes are tracked real-time and the system calculates the speed, which will be used as speed control in our system. This means when the users run in the real life, they will also feel like running in the system naturally. The user will feel the realistic aspect of our system because the speed changes with the user’s speed. Realistic 3D map from Zenrin is used in our system. The map consists of several detailed featured such as traffic signs, train station, and another natural feature such as weather, lightning, and shadow. Therefore, we would like to help the users feel more realistic and have some fun experiences. In our system, we use a head-mounted display to enhance the user’s experience. The users will wear it while running and can see the realistic 3D map environment. We aim to provide immersive experience so the users feel as if going to the real place and keep the users motivation high. Integrating realistic 3D map as part of the system will enrich human experience, keep user motivated, and provide natural environment that is similar with the real world. We hope our system can assist the users as one of possible alternatives running in a virtual environment.
