Axivity AX3 accelerometer validated against Qualisys optical motion capture, with a hand-moved Wii Remote (2015)

Equipment-validation recordings comparing an Axivity AX3 accelerometer against a Qualisys optical system, including a hand-moved Nintendo Wii Remote carrying optical markers as a reference. Recorded in 2015 in support of the micro-rhythm work published as Danielsen, Haugen and Jensenius (2015). Two of the three Qualisys takes, including the Wii Remote take, survive only as proprietary .qtm project files and cannot be read without commercial Qualisys software; the AX3 side is open CSV and CWA throughout. Session video identifies the researcher and is withheld.Funding.
