Added two pan potentiometers to a vanilla DJ mixer. Together with the cross-fader they form a square of four tap-to-ground pots.
A frame without picture, but with sound. Controlled by a radar sensor.
Concert series curated by Gregor Hotz with 5 evenings juxtaposing the “Empress of Sounds” against “The Man with the Horn”. Or music by Alvin Lucier interpreted by women vs. saxophone soli played by men. The Lucier pieces were mostly realized with digital technology. In particular “Music for Solo Performer” was interpreted using a multi-channel alpha wave sensor and a periodicity detector implemented in MaxMSP.
Second prototype, now complete with DC-DC converter and OpAmps for GSR and the optical pulse signal. The board matches the size of the Lantronix Matchport.
First GSR prototype
Decided to base the sensor system on Cypress’ PSoC architecture to explore the possibilities regarding its configurable analog subsystem. For now I’m using it to control the gain of the second stage GSR amplification.
Regarding wireless transmission we settled on WLAN and chose a Matchport module from Lantronix.
The cables you see in the picture clip onto standard electrodes.
New project: eMotion
The eMotion project aims to analyse the experience of museum visitors by tracking their position as well as biometric parameters.
My contribution will be a wireless GSR sensor to measure skin resistance and heart rate, while tracking will be accomplished by ubisense UWB tags.
The team includes psychologists, sociologists, researchers in art theory and visitor studies, musicians, artists, programmers, and designers.
