Origin Data Lab Technical Field Note #23: Hands are in view 75% of the time; an off-the-shelf detector finds a quarter of them: MediaPipe on head-mounted fisheye work video

Origin Data Lab Technical Field Note #25: How much of 2.6 hours of egocentric work video is usable? A per-second QC index: 85% sharp, about half with hands at work

Origin Data Lab Technical Field Note #15: How much does head motion blur egocentric video? Measured over 2 h 25 min of real work

Origin Data Lab Technical Field Note #24: 3D hand skeletons from a head-mounted stereo pair during real work: hands 28–42 cm away, palm segments stable to 4–10% per frame

Origin Data Lab Technical Field Note #10: Can you trust the clocks? Frame, stereo and IMU timing of a stereo+IMU egocentric rig, measured

Origin Data Lab Technical Field Note #20: Stable is not the same as correct: the calibration file saved with every recording was for 800×600, the video is 1600×1200

Origin Data Lab Technical Field Note #22: Checking stereo sync from the outside: a flashing monitor puts left and right within 0.15 ms

Origin Data Lab Technical Field Note #18: Don't pair stereo frames by their counters: per-session offsets of up to 3,009 frames, true sync 15 µs
