Video: Drancing suit 2002: variable frequency + variable amplitude mode

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes and the frequencies of 5 x 3 = 15 pure sinusoidal oscillators.

One can hear "beat" frequencies generated by similar frequencies corresponding to different accelerometer channels, such as when the arms are raised to similar levels, which effect can be exploited for musical nuance and for movement therapy to measure symmetry of posture.

Data
Medium: 
MP4
Duration: 
01:19
Camera type: 
lo-res webcam
Notes
Note: because the frequencies achievable by body movement are very low compared with audible oscillator frequencies it is not possible to demonstrate true frequency modulation (FM) with the variable frequency oscillator (VFO) mode.
Recording note: the video is lo-res webcam, and the audio is subject to poor signal-to-noise.
