Pulse Index

"Pulse Index" is an interactive installation that records participants’ fingerprints at the same time as it detects their heart rates. The piece displays data for the last 765 and over participants in a stepped display that creates a horizon line of skin. To participate, people introduce their finger into a custom-made sensor equipped with a 220x digital microscope and a heart rate sensor; their fingerprint immediately appears on the largest cell of the display, pulsating to their heart beat. As more people try the piece one’s own recording travels upwards until it disappears altogether —a kind of memento mori using fingerprints, the most commonly used biometric image for identification.

The project exists in a small plasma version which features a 58 inch HD screen hung in portrait mode and in a large projection version which can be as large as desired.
