A team of Google engineers in Japan created a keyboard in the shape of a keycap that can be worn as a hat. The device contains a 6-axis inertial sensor that can read the hat’s positioning.

YAMAGATA--Hats off to Vietnamese artisans who have come to the rescue of a long-established festival here that is famed for its beautiful dancers holding “hanagasa” in their hands.

Under the hood, the hat uses an M5Stick C Plus and, to our dismay, a micro switch that wasn’t even made by Cherry. Oh well — we landed on the clicky side, so that’s great in our book.
