The biggest graphics tablet in the world
This video has been shared on many tech lovers websites, before people actually found that already existing technologies were used : a video projector, an ink-free stylus, and a work surface modified in order for react as if it were numerical paper. It’s impressive, especially for those who are more used on painting on big surfaces rather than a tiny computer screen, but there are a lot of drawbacks to such a system: the user’s shadow created by the projector on the work surface, the need of being in a dark room in order to see the image, the low resolution of video projectors, no pressure levels as on a real graphics tablet. This explain why this solution is not commercialized, especially considering the astronomical cost of a video projector. Especially when you have such a competitor as Wacom’s Cintiqs and Tablet PC with Penabled technology, which I’ve already spoken of in this blog.
