Dynamic projection mapping onto deforming non-rigid surface

We realize dynamic projection mapping onto deforming non-rigid surface based on two original technologies. The first technology is a high-speed projector “DynaFlash” that can project 8-bit images up to 1,000 fps with 3 ms delay. The second technology is a high-speed non-rigid surface tracking at 1,000 fps. Since the projection and sensing are operated at a speed of 1,000 fps, a human cannot perceive any misalignment between the dynamically-deforming target and the projected images. Especially, focusing on new paradigms in the field of user interface and fashion, we have demonstrated dynamic projection mapping onto a deformed sheet of paper and T-shirt. Also we show that projection to multiple targets can be controlled flexibly by using our recognition technique.

Creative ideas! Projecting on ping pong balls in a pool.

Pool Party from Red Paper Heart on Vimeo.

UrbanDaddy challenged us to create a memorable interactive experience in water. Our desire was to create animations that party-goers could swim through. Initially we had no idea how to make this a reality.

Pools are not exactly the most projection ready surface, and initial brainstorms produced many more challenges than we had anticipated. In researching a solution, we had to overcome the fact that projection doesn’t work on the surface of water, it becomes distorted if you project through it, and pool parties are notorious for more standing than swimming. To make something truly interactive, we needed to get everyone in that pool!

We reacted as any any normal person would, and promptly put in and order for 65,000 ping pong balls, enough to cover the entire surface of the pool. To go with our new screen, we created an application which mapped to the pool and displayed a floating river of graphics, pulled by an invisible tide. Audio reactive visuals bumped along with the various dj’s and musical acts taking place poolside. The tactile quality of swimming through ping pong balls, combined with animated colors and light created an interactive event worth telling stories about.

Wicked object mapping by Johannes LDC Guerreiro

various objects – projection mapping from Johannes LDC Guerreiro on Vimeo.

Some objects deliver an attractive surface for throwing light with a beamer on it. Some others show an intensive inside space, like the harddisk. the projections are proposed to be frontal from one top direction – so its always about the top surfaces to be projected on. In some cases its possible to work with free forms, which do not break the 90° angle of the top surface like the hemisphere obejct, or the sound-damping peaks…
