Rather than a touchscreen, the arcade game uses a mysterious "BOOSTER" system, seen above. Is it an Etch-a-Sketch type situation? We don't know. We do know that Taito promises a "very different control experience" from both other music games and the existing Groove Coasters.
The cabinet will make its debut at the Japan Amusement Expo on February 15 and 16. If you have an iOS device and haven't tried Groove Coaster, get Groove Coaster Zero for free and check it out. Put your headphones on if you're at work.
