It seems that finally we have the device that every Google Glass fan wanted, but it wasn’t Google creating it: some research scientists at the National Physical Laboratory in the U.K. in collaboration with manufacturer Colour Holographic did, and the concept looks awesome.
Like it is for Google Glass, this device clips on a side of the wearer’s glasses and the creators claim that it suits to be used by everyone, from surgeons to firefighters, helping men to become enhanced in any profession they do through augmented reality.
There are anyway some big differences between this wearable and the Big G product, the most important of which is the fact that with this prototype you don’t have to look up to see the screen:
“Normally when we want to see things from our phones or our computers, we need a screen to look at. But this way, we could do away with a screen and just have the image projected directly into our glasses and into our eye,” said John Nunn, one of the research scientists that are working on this project in an interview with Motherboard.
In fact, the device overlays transparent images over what the wearer is already seeing, with a technology based on holograms. Think about how much this could be useful for enhancing many aspects of our lives, from the most common to the special ones; Manuel Ulibarrena, R&D Manager at Colour Holographic, said, “If you’re walking down the street, instead of looking at your mobile you can see a transparent map of where you are going with arrows and directions showing where you want to go.”
The NPL’s prototype comprises a micro-display, a lens, a glass plate and holographic glass slitters inside each end of the glass plate. As the user wears the device, a hologram bends the red, green and blue parts of light by 90 degrees which causes the light to reflect inside the glass and to travel over the wearer’s eye. Another hologram then bends the light again so that it is visible to the human eye.
For now, as we said, it is just a prototype, but soon it could become the headset we were all waiting for.
