Spatial Computing Needs a Keyboard.
Headsets have solved the display bottleneck. You can have infinite monitors floating in space. But text input in AR/VR remains stuck in the 1990s. KeyboardHand provides the necessary high-bandwidth tactile bridge.
The Text Input Bottleneck
Whether you are using an Apple Vision Pro or a Meta Quest, the primary hurdle to getting real work done (coding, writing, data entry) is text input. Voice dictation fails in open offices. Floating virtual keyboards are agonizingly slow and induce "gorilla arm." Bringing a mechanical keyboard into VR requires clunky passthrough windows just so you can see your keys.
KeyboardHand abstracts the keyboard entirely. By resting the sensor bar on your desk or lap, it creates a 60cm wide 3D tracking volume. You type in thin air. Because it utilizes chording, you do not need to look at your hands—ever. Your visual focus remains 100% on your spatial displays.
"The dream of coding on a beach with a headset was always ruined by the fact that you still had to drag a heavy aluminum keyboard with you. Optical chording makes the input as virtual as the display."
Absolute vs Relative Positioning
Our 850nm IR array uses relative positioning. This means it tracks the geometry of your fingers relative to *each other*, not relative to a fixed point on the desk. If you shift your posture, lean back, or move your hands to your lap, KeyboardHand instantly calibrates to the new center point.
This is a massive leap forward for ergonomics. You can work for 8 hours in an HMD without being anchored to a desk surface, permanently dropping your RSI risk.
