AX3 accelerometer validation against Qualisys optical motion capture (2015)

Equipment-validation recordings from the fourMs Lab (RITMO, University of Oslo, 2015): an Axivity AX3 accelerometer recorded concurrently with Qualisys optical motion capture, with a shaker ground-truth block and a sound-synchronisation test. This test supports the motion-capture methodology of Danielsen, Haugen & Jensenius (2015), 'Moving to the Beat' (Timing & Time Perception 3(1-2), 133-154; doi:10.1163/22134468-00002043).

Part of the fourMs/RITMO technology-comparison series.
