Prototype screen can detect who is who and where they are touching.
The Gunze touch panel uses electrodes around the edge of the display and could accurately distinguish who is touching the screen and register multiple users. The touchscreen prototype was recently unveiled at the 11th International Nanotechnology Exhibition & Conference in Tokyo, Japan. The panel was developed for arcade table games where multiplayer tracking is essential, for example betting games or spot-the-difference games.
Currently, the panel can only recognize users after the electrode has been touched. This process could prove frustrating and impractical for gamers. There are still a lot more tweaks to be nutted out before we see the Gunze touch panel for commercial sale.
