Google Japan has introduced a quirky keyboard innovation called the Gboard CAPS, which is a hat resembling a single keyboard keycap. While it can be used to type the alphabet, it's more of a fashion statement than a practical keyboard. Similar to past experiments, it's not intended for production, but tech enthusiasts can create their own using cardboard or 3D printing. The Gboard CAPS can register single keystrokes via Bluetooth and relies on a six-axis inertial sensor to input characters based on the wearer's facing direction, potentially leading to some amusing spins while typing. This playful creation follows Google Japan's history of unconventional keyboard alternatives, from the impractical Gboard Stick to keyboard-covered teacups. You can find all the necessary 3D models available for download for free on GitHub, as well as a shopping list for all the electronic components you'll need, instructions on how to put them all together and even a link to the software needed.
