To shift the perception data will be gathered from multiple (ambient) sources. This means tapping into public data sets for broad context. It also means gathering hyper-local/personal data via an arduino or similar microcontroller (probably ESP8266) for sensing the individual. These data streams will be combined to produce a visual output using jitter. This result aims to represent the other humans in a manner to emphasize personality and not the emulation of the technicality in face to face exchanges. | To shift the perception data will be gathered from multiple (ambient) sources.

''Different implementations of the algorithm were tried in Max. None yielded a convergence of the phases of the oscillators. Therefore the project was cancelled.'' | |||
The installation "distance communication" explores and reflects on (romantic) relationships at a time where partners are apart. Their lives don't take place in the same environment anymore and are open to different influences. It takes effort to stay in sync even though a distance may be bridged by modern communication means. Two blinking LEDs represent the partners, the blinking rhythm their respective lives. | |||
The technical setup consists of two LEDs driven by a microcontroller and sensed via a light-dependent resistor. A small computer (laptop or small form factor PC) runs both Max and a video conference software to display "the other". The Max patch and the "other" are displayed on a screen or video projector. The Max patch tries to synchronize the respective blinking pattern by leveraging the well studied behaviour of fireflies. A microphone on the floor picks up ambient sound. If this audio level exceeds a given a threshold the blinking of one LEDs is triggers / reset to introduce disturbance in the process. The installation may be presented with both parts in the same room or one part off-site somewhere else. | |||

The firefly model turned out to be insufficient for the current setup due to the small number of agents. The interaction has been remodeled from first principles based on two harmonic oscillators and the Kuramoto–Daido model for phase locking. | |||

Observing the equation system over time shows the expected behavior (when implemented in Python). | |||
