Structured Light vs RGB

Most optical hand-tracking systems, like Apple Vision Pro or standard webcams, use RGB optical sensors. They take a photograph, send it to a processor, and extract the hand data. This means a malicious actor could theoretically intercept the video feed and see your face, your screen, or documents on your desk.

KeyboardHand's 850nm IR array does not take photographs. It projects a grid of invisible infrared dots and measures how they warp over physical objects. The resulting data is a sparse 3D point cloud of geometry. It cannot read text. It cannot resolve skin tone or facial features.

Local Inference

All translation from "point cloud geometry" to "keystrokes" happens locally on the device's internal MCU. The device never connects to the internet, requires no cloud processing, and outputs standard keystrokes via USB. This makes it safe for enterprise deployment in secure environments.

Data Collection Policy

We do not collect typing data. We do not have access to your chording macros. If you use our developer SDK to build custom applications, all data remains strictly local to your machine.
