Show summary
This article describes the design and construction of a collection of digitally-controlled augmented acoustic guitars, and the use of these guitars in the installation \textit\{Sverm-Resonans\}. The installation was built around the idea of exploring `inverse’ sonic microinteraction, that is, controlling sounds by the micromotion observed when attempting to stand still. It consisted of six acoustic guitars, each equipped with a Bela embedded computer for sound processing (in Pure Data), an infrared distance sensor to detect the presence of users, and an actuator attached to the guitar body to produce sound. With an attached battery pack, the result was a set of completely autonomous instruments that were easy to hang in a gallery space. The installation encouraged explorations on the boundary between the tactile and the kinesthetic, the body and the mind, and between motion and sound. The use of guitars, albeit with an untraditional `performance’ technique, made the experience both familiar and unfamiliar at the same time. Many users reported heightened sensations of stillness, sound, and vibration, and that the `inverse’ control of the instrument was both challenging and pleasant.

Show summary
We present the results of a series of observation studies of ourselves standing still on the floor for 10 minutes at a time. The aim has been to understand more about our own standstill, and to develop a heightened sensitivity for micromovements and how they can be used in music and dance performance. The quantity of motion, calculated from motion capture data of a head marker, reveals remarkably similar results for each person, and also between persons. The best results were obtained with the feet at the width of the shoulders, locked knees, and eyes open. No correlation was found between different types of mental strategies employed and the quantity of motion of the head marker, but we still believe that different mental strategies have an important subjective and communicative impact. The findings will be used in the development of a stage performance focused on micromovements.

Show summary
This article presents the development of the improvisation piece Transformation for electric violin and live electronics. The aim of the project was to develop an “invisible” technological setup that would allow the performer to move freely on stage while still being in full control of the electronics. The developed system consists of a video-based motion-tracking system, with a camera hanging in the ceiling above the stage. The performer's motion and position on stage is used to control the playback of sonic fragments from a database of violin sounds, using concatenative synthesis as the sound engine. The setup allows the performer to improvise freely together with the electronic sounds being played back as she moves around the “sonic space.” The system has been stable in rehearsal and performance, and the simplicity of the approach has been inspiring to both the performer and the audience.

Show summary
We report on the development of a video based analysis system that controls concatenative sound synthesis and sound spatialisation in realtime in concert performances. The system has been used in several pieces, most recently Transformation for electric violin and live electronics, where the performer controls sound playback through motion on stage.

Show summary
Trenger vi egentlig musikere, forfattere og filmprodusenter nå som KI kan gjøre jobben? Vi tar diskusjonen om hvordan KI påvirker kreativ næring og kunstneriske prosesser. Debatten raser rundt bruken av kunstig intelligens i Kultur-Norge.
Forlaget Bonnier brukte nylig et KI-generert bilde som forside på en bok, og "KI-bandet" Vestavind er booket til flere norske musikkfestivaler.
Flere kjente kunstnere og artister tar til orde for tydeligere regulering eller forbud av KI for å beskytte kunstnernes virke og opphavsrettigheter.
Hva er egentlig kreativ KI? Hvordan påvirker kunsten KI? Hvordan kan vi beskytte kunst og kunstnere, samtidig som vi tar i bruk ny teknologi?

Stillness 2025 (Deichman): a group standstill performance with wearable physiology (Equivital).
doi:

Full text in Research Archive
Show summary
A dataset captured at the Stillness 2025 performance at Deichman Bjørvika in Oslo. 27 people took part in a 2-hour public standstill/walking performance on 9 October 2025. 16 of them wore Equivital EQ02 LifeMonitor chest sensors and are included in this dataset. Each vest logged 2-lead ECG (256 Hz), tri-axial accelerometer (256 Hz), thoracic respiration (25.6 Hz), beat-to-beat RR intervals, and a 15-second device summary (heart rate, body position, motion state, skin temperature, quality flags). A processed 5-second quantity-of-motion table is provided for all 16 participants. Timestamps are UTC, and every file is trimmed to the 2025-10-09 performance window; the multi-day pre-performance setup recordings are not part of this deposit.
