Mitsubishi is working on a floating display
While it's not the 3D Star Wars hologram you're hoping for, Mitsubishi is developing a system to project video in mid-air, which it hopes to commercialize in time for the Tokyo 2020 Olympics. To pull it off, the company is using two types of optical tech: a beam splitter, which divides incoming photons into reflected and transmitted light, and a retro-reflective sheet that bounces light back in exactly the same direction it came from. By arranging them just so with a display (below), the light reconverges to form an image that appears to float in the air.
Samsung patent uses projector and electronic pen for virtual screen
We're a little confused, since yesterday the word was that Samsung had teamed up with Iljin Display for packing a projector into their phones, but we guess they need to have their bases covered. Samsung has just been granted a patent they submitted in 2004 for a virtual input interface, a bit similar to that virtual keyboard from iTech. It involves a phone-based projector, an "electronic pen," a "position detector" and some handwriting recognition stuff. Yeah, we know, real technical-like, but it sounds like yet another vain attempt to create a better way to input text and other info into a mobile phone. Can't fault them for trying, but let's hope the mind-reading efforts are well under way.[Via Unwired View]
