Microsoft's wearable projector makes the world a screen

Microsoft Research is showing off a prototype for a wearable projector that lets users turn any surface into an interactive display akin to a touch screen. The Wearable Multitouch Projector combines a camera and a projector to allow users to dial phones, find maps and do other jobs that now require a computer or smartphone. Writer Mike Luttrell says such a prototype could someday be integrated with a person's clothing.

If you think wearable tech is the way of the future, then this is for you. 

Microsoft Research's Hrvoje Benko has introduced what he called the Wearable Multitouch Projector. Yes, he hasn't gotten the whole cool name thing down just yet, but don't let that fool you when it comes to the 


awesomeness of the device.

  

Basically, the contraption is a Kinect camera that you wear on your shoulder. Via some wiring and other accessories to ensure the device can stay perched on you, it can display an interactive image on a nearby wall.
This means that you'll have your arms and hands free to point to and interact with the projection. It doesn't look really elegant but this is obviously just a prototype.
This is just an early look at what might be part of our everyday garb in the future. When you think about it, everything has been turned into high-tech, with the exception of clothing.
It's the one thing we need every day that doesn't have a power source, can't display dynamic information, and has no means of external communication. That's about to change, and we're starting to see it with things like jackets that have internal wiring for phone charging and the like.
So while this particular contraption doesn't look that practical, it's indicative of what's to come. That's both awesome and a bit intimidating to think about, isn't it?

Wearable video coat

This is just too nerdy.

[David Forbes] is no stranger to the weird and esoteric, so he created a color LED TV built into a lab coat. He plans on bringing it to Burning Man next month.
The RGB LEDs are mounted narrow flex boards, providing a 160×120 pixel NTSC display. Video processing is taken care of by an Xilinx FPGA that takes the YCrCb video feed from a video iPod and converts it into four separate RGB streams for the front, back, and the two sides. The requisite controls for brightness and color are on the shoulders.
Of course, the build wouldn’t be over-the-top without the ability to plug a Nintendo into a lab coat, so there’s an NTSC input on an RCA jack. Everything is powered by two 11.1 V, 5Ah radio-control LiPo battery packs that should power this for a while.
