TECHNOLOGY
BoardHand relies on a custom stereo infrared optical array, rejecting ambient light interference and processing spatial data entirely on-device to ensure sub-millimeter precision without CPU overhead.
The Sensor Array
Unlike webcam-based hand tracking which struggles with latency and occlusion, BoardHand uses three discrete 850nm IR cameras recessed into the top chassis. Operating at 120Hz, these sensors triangulate bare hands within a defined tracking volume extending 150mm above the keycaps.
Technical Specifications
| Sensor Type | Monochrome Global Shutter CMOS |
|---|---|
| Wavelength | 850nm (Near-Infrared) |
| Polling Rate | 120Hz native (Interpolated to 1000Hz USB polling) |
| Spatial Resolution | 0.1mm at center volume, 0.5mm at edges |
| Compute Processor | ARM Cortex-M7 (On-device DSP) |
On-Device Processing
Sending raw point cloud data over USB creates unacceptable latency for professional input devices. BoardHand processes all skeletal tracking natively on its internal ARM Cortex-M7 MCU. The host OS simply sees standard HID mouse and keyboard events. No drivers required.
