Technically, cloth is a "deforming non-rigid surface," so projecting a stable image onto clothes is a big technological challenge. To solve it, Ishikawa Watanabe Laboratory combined two new techniques that allow stable projection of an image onto clothes even as they move.
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.

“You’ve probably heard that America’s billionaires have gotten at least $282 billion richer during the pandemic,” writes Rain Noe on Core77. “What will they spend that extra cash on, once this is all over?” Rain recommends the Aviro Business Jet Explorer, a private jet with an outdoor deck. It’s just a concept design for BAE […]
Police procedural novelist Michael Connelly is a connoisseur of jazz music so it’s no surprise that his most famous character, LAPD detective Hieronymus ‘Harry’ Bosch, is also a deep enthusiast of the genre. (Connelly has a page on his personal Web site all about the “music in the novels.”) Illustrator Russell Walks took those cues […]
Most parents know that giving their kids educational toys and other projects will expand their minds. But what many might not realize is that physical play is actually building their mental abilities as well. Studies are still in beginning stages, but some early research supports the theory that kids who get the chance to get […]
Not every house has a fireplace. And to be honest, not every homeowner wants to deal with the hassles and maintenance of a fireplace. But it’s tough to argue that the intoxicating glow and dance of a licking flame isn’t mesmerizing, not to mention all of a fire’s practical uses. For those looking to enjoy […]
Knowledge is power. And a company that knows who its customers are is far more likely to see those customers return. On the web, information gathering often comes in the shape of an online form. Whether it’s a registration, a contest, an order, or just a simple contact, those opportunities to engage with users and […]
