Abstract:
In this study, we report an implementation of reproducing stone trajectory data with VR technology to support curling. The ”Stone Tracking System”, which is used in public curling facilities in Japan, tracks an infrared transmitter attached to a curling stone using an infrared camera to obtain coordinate information and reproduce the trajectory of the stone from the time it is thrown until it stops on a sheet with a two-dimensional representation. The ”Stone Tracking System” was used to measure a set of stone trajectory data. Furthermore, we constructed a process and implemented a database to convert the obtained trajectory shot data from 2D to 3D. Additionally, a curling hole was constructed in a VR space, and a system was built to display the stones, trajectory, and some of the shot information in layers. By using this method, users of the system can project multiple shots on an ice sheet in the VR space, check and compare shot results from any viewpoint, and superimpose shots, whi
ch is not possible in real space.
