Instead of moving your hand to the keys, Gboard’s conveyor-belt version sends the keys to your hand. Each of its four belts carries 29 keys, upper and lowercase letters included, so one hand reaches everything. It’s Google Japan’s October 1 keyboard (a nod to the 101-key layout); there’s no product to buy, but the 3D-print models, circuit boards and firmware are on GitHub for anyone who wants to build one.
