Milieu Reverb
Medium: digital media, generative videos, natural user interfaces

Milieu Reverb consists in a series of short videos recorded in public urban spaces and reworked through digital media. Computer vision algorithms are used to detect movements of people in real-time and generate an artistic impression of their flow through the city. It brings to the fore issues such as surveillance, social behaviour, crowd dynamics and effective utilisation of public space. Videos will be recorded at different locations and different times of the day. Each time of the day entails different visual and sonic aesthetics. As people walk across the public space, their movements are picked up by the tracking software. Each moving section of the image is assigned a colourful view frame; once moved, such view frames leave permanent marks in the image, akin to a long exposure photograph. Overtime, a pattern of movement emerges from the cumulative stains in the video record, revealing the underlying flow pattern of the local population across the particular urban space.

The videos collected daily contribute content to a generative digital art exhibition at Culture at Work’s Accelerator Gallery, where a depth-view camera based interface allows people to play various movies concurrently, tapping into the continuously evolving soundtrack of the city, inadvertently composed daily by their own inhabitants.
