1.0 | Installation
The installation SARoskop is dealing with the visualisation of electromagnetic waves, which are imperceptible for the human sensory spectrum. The complete net of SARoskop-objects is composed as an interactive sculpture reacting sensitively to the data of the proximate surrounding and transforming it into movement and interdependent oscillations.
The work SARoskop deals with the visualization of electromagnetic waves which are not discernible for the human sensory spectrum. The net of the single objects forms an interactive sculpture which reacts sensitively to data from the direct environment and moves this in movement and mutually conditional oscillations.
2.0 | Space requirements
Variable dimensions (installation is adapted to the space situation)
(example installation construction February 2007, Moltkerei Cologne: approx. 4-metre height x 4.80-metre width, see also images/ movies DVD) 25 single objects in a net/matrix of steel cables, power supply unit, cable
3.0 | Detailed text
As a person one orientates himself within certain frequency responses. Nevertheless, the surrounding spectrum is bigger than is to be perceived in the audible (15 hertz to 20.000 hertz) or visible area (400 nm, ultraviolet to 700 nm, infrared). The installation transfers the electrosensory taken up data of a specifically chosen frequency spectrum in a perception visible and audible for the participants.
Realization (form, material)
Role of the participants and form of interaction:
The well-chosen spectrum encloses 900 to 2400 MHz, i.e. frequency from the area of cellular radio, WLan, television, UMTS, radar, broadcasting company, telemetry, microwave etc. The participants / viewer of the installation can influence the movement and the intensity of the reaction of the object-matrix by application, e. g. of their mobile phones. At the moment of the transference of data via mobile phone the intensity is taken up and transferred on the mechanics by the sensor technology and the aerial. (Both elements are settled on the circuit board, structuring and forming each single object in connection with the mechanical layout.) In succession the movement of the mechanics is set into an accordant rhythm. The intensity of the amplitude increases with the amount in data transfer and nearness of any active devices.
The SARoskop is therefore an interactive sculpture reacting sensitively to data of the proximate surrounding and transforming it into movement.
