In this study, we developed a small, transparent, spherical POV display device for board game applications. In order to use the device as a frame for board games, portability is the most important issue. Therefore, our goal is to create a system that can be moved freely without the need for external cables or batteries by using wireless power supply technology. This display has a highly transparent hologram, allows 360-degree viewing, and multiple displays can communicate via WiFi with a control microcontroller. In addition, by using face detection with a camera, a different picture can be displayed for each player. To evaluate our concept, we created a prototype system and evaluated it. As a result, we were able to confirm the desired functions.
