--- first_captured: 2026-03-28 sources: - sources/ideaflow/2026-03-28_build-better-emg-gyro-bracelet-than-meta-smart.md status: raw tags: - hardware - hci - wearable - bci title: EMG + gyro bracelet type: idea updated: 2026-04-10 visibility: public-edit --- # EMG + gyro bracelet build a better EMG + gyroscope bracelet than Meta's smart glasses wristband for hands-free computer control from far away — no-mouse cursor control, clicking, and shortcuts. the demo would be controlling a computer without touching it. this is the wrist-based version of the [[pupilometry-glasses|pupilometry glasses]] eye-tracking approach. both address the same problem: hands-free computer interaction. the bracelet approach may be more practical since it does not require glasses and EMG can detect fine hand gestures. --- ## timeline - [2026-03-28] captured — emphasis on building a "hella cool demo"
