Movement of my heart is replicated outside my body: Metal pins prod the skin of
my back according to a Doppler heart sensor signal. The sensor registers my heart's
activity in real-time. Thus, a cybernetic haptic feedback loop is established.
I am standing in the first space. An AngelSounds Fetal Doppler (a cheap consumer
device for pregnant women to listen to their unborn baby’s heart beat) is attached to
my chest and registers the movements of my heart. A prepared loudspeaker is
attached to my back. The Doppler signal is sent to this loudspeaker. However, the
loudspeaker’s cone has been removed and doesn’t produce sound. The loudspeaker
coil merely follows the movements of the contours of the Doppler signal. Pieces of
metal are attached to the coil and prod my skin.
In the second space, a video monitor shows a real-time close-up of the part of my
back where the metal pins touch the skin. Next to the monitor, a loudspeaker is
suspended from the ceiling. This loudspeaker loudspeaker is unmodified and emits
the sound generated by the Doppler sensor in the first space.
