Posts on interactive installations, sensing, and real time media systems.
Real time people tracking for interactive installations is rarely about perfect data. The main problem is keeping interaction clear when the space is crowded, lighting changes during the day, and the background is visually complex.
Passive interaction is often the most effective form of interactivity in public space. It does not demand attention, does not require instructions, and still lets presence shape the work. In an interactive installation, the goal is not to create a task for the visitor, but to let real world movement become an input to real time visuals while the composition remains stable on its own.
In sensor driven interactive installations, the most fragile part is often the IO layer. It has to accept different formats, keep timing stable, and stay debuggable while artists and engineers keep changing things on site.
