Gboard Dial Version Opensource concept by Google Japan 

The Gboard rotary keyboard—officially named the "Gboard Dial Version"—is a playful, open-source concept by Google Japan that replaces traditional keys with nine rotary dials, inspired by vintage rotary telephones.

Instead of pressing keys, the user places a finger into a dial hole and rotates it to select a character. The dial, equipped with modern sensors, snaps back after release, registering the character electronically. Each dial represents a set of letters, numbers, or functions, with the return (Enter) key also having its own dedicated dial.

Features and Usage

Nine dials cover the QWERTY set, numbers, and function keys.

Rotating a dial selects input, offering deliberate typing and reducing typing strain.

A mechanical “buzz” sound during dial rotation mimics the tactile feedback of retro devices.

Google also released an accessory stand that turns off your webcam when a mouse is placed on it, reminiscent of hanging up on vintage phones.

This keyboard is not commercially sold, but all plans, CAD designs, and firmware are freely available on GitHub for enthusiasts to build their own using 3D printing and electronics. The project celebrates the blend of analogue aesthetics and modern hardware and is a commentary on reimagining input methods and digital nostalgia.

Practicality

Though charming and satisfying in its retro design, typing speed is much slower than a regular keyboard. The Gboard Dial Version is primarily for tech enthusiasts and makers, not everyday work—merging playful engineering with nostalgia.
