interactive laser video feedback
Interactive laser video feedback turns projection mapping into a live loop: a camera, a projector, and a handheld laser drawing light that grows on its own.
Most people know audio feedback. A microphone gets too close to a speaker and the signal spirals into a screech. Video feedback is the same loop with light, minus the screech. A camera watches the wall a projector is lighting, so each frame contains the last, reprojected 30 times a second.
In a dark room the loop sits empty. Then the laser clicks on. One green dot gives the camera something to see, every pass picks up a little noise, and the dot grows. It spreads and morphs into forms that read as alive, more grown than rendered. None of it is scripted.
A body between projector and wall casts a shadow, and the shadow is the opposite of the laser: it blocks the loop instead of feeding it. Guests herd the forms, carve through them, or wipe the wall clean and start over. A laser, a shadow, a wall. That is the whole interface.
where it works
Video feedback installations fit events and venues that want a crowd: corporate events, parties, museums, and science centers.
Interactive laser video feedback is interactive projection mapping in its most open form. No menu, no instructions. Guests figure it out in seconds and keep discovering for hours. That open loop is what gives this interactive art installation its replay value.
At an event the piece changes what guests do. Instead of orbiting the bar, they step into the projection and steer it. Strangers end up composing together. It draws a crowd by design, so it belongs in a large room or an open corner, never a tight hallway. The same pull suits corporate events, parties, museums, and science centers.
The requirements are short. A light colored wall, a dark room, and lighting that stays put, because the loop is calibrated to the room. NOVA Light Labs designs and tunes the system on site, then the laser goes to the guests.
