Joanie Lemercier demonstrated some projection magic on Vimeo. The talent found a way to create projections appearing to float in the air and following the viewers perspective, overlayed with the real world. Unlike AR and VR, viewers don’t need headsets, devices or screens to see these.
First of all, this is NOT a hologram. Holograms are still images captured on photographic plate with a laser, and were invented in 1971. The developer calls his experiments no-lograms. Here’s what the artist has to say about the experiments:
I’m obsessed with projections in mid-air, ever since I first saw Princess Leia ‘so-called’ hologram, and I dreamed for years of having a go at Tom Cruise’s UX in minority report.
I’ve used various techniques to explore similar aesthetics: peppers ghost (used in the Tupac Coachella concert), semi transparent screens, mirrors and lenses, which are often referred to as “holograms” but are in fact cheap tricks and just 2d projections.
I’m now developing a technique using super fine particles of water, high pressure gaz and custom nozzles, to create true volumetric projections, and build large installations in public spaces. Technically there is no limitation in size / scale.
I use common tracking technologies (depth sensor and image analysis) to allow interaction between the user/audience and the projections.
My works explores geometric patterns, repetitive shapes in nature, and the similarities we can witness when looking at the structure of the universe at various scales. The volumetric projections are also a great medium to question the nature of reality, and how technology can modify our perception of the world we live in.
