Blind Spots is a site-specific cybernetic installation, created in collaboration with Mark IJzerman, that focuses on communication that we cannot perceive with our human ears. By tuning in to specific bat species present in the Goffertpark in Nijmegen (NL) and making them audible and visible, the installation plays with elements that lie beyond the threshold of our perception, but which surround us all the time.

Based on previously collected ultrasound recordings and real-time ultrasound produced by nearby bats, the installation creates a multi-species audiovisual dialogue between the artistic duo and their non-human counterpart.

Speakers placed randomly at different distances and heights in a bush play a multi-channel sound composition whose movements are visualised by black light LEDs suspended above them. These specific lights attract numerous insects, which in turn attract bats into the installation, whose presence is detected by an ultrasonic sensor and directly incorporated into the composition.

In addition to a reference to the perceptual limits of our human bodies, Blind Spots raises a more philosophical question. What do we know about the capabilities of these beings and how can we understand their perspective?
