Nervous Field | 2014
“Nervous Field makes use of electric field sensing. This refers to a family of noncontact methods for measuring the position and orientation of the human body, or parts of the human body such as a hand. Electric field sensing has been used for human-computer interface, for creating new musical instruments and in the automotive industry as a solution to the rear facing infant seat problem. Electric field sensing is also an important sensory modality for several species of fish, dolphins and bees. Technological applications of field sensing, from the Theremin to the capacitive elevator button, have not been limited to simple proximity detection tasks. The physical user interface is an increasingly signifcant factor limiting the effectiveness of our interactions with and through technology…
According to the measured field strength, the sound, the colour of the sound, and the volume of the sound are varied. Thus, an improvised piece of music is created from the most simple parts. The sound installation refers to the concept of aleatory music, based on aspects of chance and improvisation, as used by John Cage, Pierre Boulez, and Iannis Xenakis.”

Space Time | 2016
Everyday clocks such as wristwatches have finite precision. Eventually they require correction to remain accurate. The rate of drift depends on the clock’s quality, sometimes the stability of the power source, the ambient temperature, and other subtle environmental variables. Thus the same clock can have different drift rates at different occasions.
Clock drift refers to several related phenomena where a clock does not run at the exact right speed compared to another clock. That is, after some time the clock “drifts apart” or gradually desynchronizes from the other clock.
Time signal stations synchronize their clocks to coordinated universal time (UTC), the international standard for timekeeping. No clock keeps coordinated universal time exactly because coordinated universal time is an average time, calculated with data collected from hundreds of atomic clocks located around the world.
In Space Time the accumulated time error of an analog radio-controlled clock is measured between synchronizations. A sensor is used that records the beat-rate of the watch’s pulses. Comprising several radio-controlled clocks, the Space Time installation makes this inaccuracy audible with clocks, electronic oscillators and speakers.
Space Time uses sonification to make time tangible. Sonification is the data-dependent generation of sound, if the transformation is systematic, objective and reproducible. Then it can be used as scientific method. A distinction between data and information is irrelevant with regard to the definition: information like, for instance, a message can always be represented numerically and thus be understood as data. Sonification refers to the technique and the process; the algorithm. Sonifications of the measured sensor data may be heard as music. According to the measured time inaccuracy, the sound, the color of the sound, and the volume of the sound are varied. The time inaccuracy adds a certain chance aspect to Space Time.
