Muscle to HID. Any CAD.

EMG-CAD-HID is a wearable forearm band: 32 dry electrodes, gesture classification on a Teensy microcontroller, output as a standard USB HID device. Any CAD that already understands a mouse or keyboard can listen — no plugin, no custom API.

How it's built

Acquisition

32 dry electrodes around the forearm into an analog front-end. Muscle microvolts, sampled on-device.

Edge classification

Gesture mapping runs on the Teensy. No cloud round-trip for the HID path.

Native HID

The Teensy enumerates as a standard Human Interface Device. CAD software does not need to know it is an armband.
