Google Japan has once again captured global attention with its quirky innovation—a rotary-style concept keyboard inspired by vintage telephones. Named the Gboard Dial Version, this imaginative device replaces traditional keys with circular dials that mimic the iconic design of old rotary phones, transforming the act of typing into a nostalgic, mechanical experience.
The Gboard Dial Version features nine rotary dials, each assigned to different commands or letters. Instead of pressing keys, users type by inserting a finger into a dial’s hole and rotating it—just like dialing a phone number decades ago. Each rotation is tracked by built-in sensors that convert the motion into USB signals, allowing the device to communicate with a computer. Even the “Return” key is represented by its own miniature dial, completing the retro aesthetic.
This unusual concept was developed by Google Japan’s Gboard team, known for its playful and experimental approach to reimagining input devices. In the past, the team has introduced various unconventional keyboards, from banana-shaped layouts to wearable devices. These projects, while not intended for commercial sale, are released as open-source designs on GitHub, allowing enthusiasts to build and customize them at home.
According to Google Japan, anyone with a bit of curiosity and patience can assemble their own rotary keyboard using the schematics and data shared online. For those without technical expertise, the company has also provided a simplified single-dial version to make the experience more accessible.
The nine dials of the full keyboard vary in size, each covering different sets of characters or functions. When a user rotates a dial to select a specific letter, the system’s sensors detect the motion and interpret it as input. In classic rotary phones, this mechanism relied on pulse dialing, but Google’s version uses modern sensing technology for precision and compatibility with digital devices.
Adding to the retro charm, the keyboard includes a cradle-like stand similar to that of old telephones. In a clever touch, when a user places their mouse on this cradle during a video call, it automatically turns off the webcam, providing a tangible and intuitive privacy feature.
While the rotary keyboard is unlikely to replace standard layouts anytime soon, its purpose lies elsewhere—it’s a creative exploration of how people interact with machines. By turning typing into a slower, more tactile process, Google’s design encourages users to reflect on the physicality of digital communication in an era dominated by touchscreens and voice input.
