In Tokyo bars, malls and heavily trafficked areas, these machines come packed with motion-activated ads, interactive touchscreens and plenty of beer options. Often, the bar establishment provides a clean glass that a customer places on the machine's slot, and the machine takes it from there with style. A hooking mechanism secures the glass with a giant claw and tilts it 45 degrees for the optimal amount of foam. Using motion sensors, the machine can tell when the glass is full, and releases it softly on the beer mat.
