+# 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.
