A trio of researchers from the Korean Advanced Institute of Science and Technology (KAIST) recently developed an eyes-free, AI-powered, invisible keyboard interface that positions itself based on where you choose to set your hands when you’re ready to type.

Billions of dollars worth of R&D and marketing research go into building better peripherals every year. But, realistically, little’s changed since the advent of the mouse and keyboard. Touchscreens and virtual keyboards are a fair proxy for mobile users, but there’s no replacement for a full sized QWERTY keyboard you can use all ten fingers on.
