A test session was set up in a small performance space to test how different technologies compaire in their measurement of audience motions typical for classical music audiences.
A small number of volunteers wore accelerometers on their torsos and were recorded with two thermal cameras, an infrared camera (with illuminating lamp) and normal RGB in a room set to a darkness typical for concert halls (<10 lumens). They sat and watched a recording of a symphonic piece from a previous concert experiment, clapping with the recorded audience and attending to the performance between.
Analysis of these measurements will be reported at SMC 2026.
