No need to buy a TV at home
You don't have to have navigation in your car.
You don't need to bring a dictionary and translator when you go abroad
You don't need to bring your cell phone if you're in a hurry.
No headphones, no car keys ......
You're this close to living a minimalist life.
All that's missing is a pair of glasses called "Skylarks."
Recently, the world's first polarizer holographic optical waveguide AR glasses developed by a team from Southeast University were launched, named "Skylark" for its "ability to sing and dance" and "lightness as a sparrow".
The technology originated from the Institute of Information Display and Visualization, School of Electronic Science and Engineering, Southeast University, and is a new high-end display technology developed by a Chinese research team.
Putting on the glasses, a screen appeared not far from the eyes. Saying a few words at random, the screen instantly converted to speech, and two kinds of text appeared in English and Chinese, precise and clear. Next, it switched to the navigation function, and the screen indicated the current location, with arrows and text prompting the direction of travel and the mileage from the end point.
Compared to traditional AR glasses
"What's the difference between a lark and a skylark?
Yuning Zhang, professor of the School of Electronic Science and Engineering and director of the Display Research Institute of Southeast University, introduced that traditional AR glasses generally use surface relief grating (SRG ) technology, and these glasses use polarizer holographic grating (PVG). The difference is that SRG uses micro-nano-etching and nanoimprinting methods to form a periodic structure on the surface of the material based on the morphology of thePVG, on the other hand, creates a periodic distribution within the material based on refractive index changes by holographic interference methods.
"Our strengths are centered on three main areas.First, the light efficiency has been increased to 300%.Significantly improves product range and display brightness; forward light leakage has been reduced by 80%, making light leakage virtually invisible to bystanders, enhancing product privacy and social friendliness; PVG's unique polarization multiplexing technology also ensures picture continuity and uniformity while realizing a larger field of view and exit pupil size.Secondly, costs have been significantly reduced.The main preparation process of PVG technology only requires the use of wet coating and holographic exposure, without the use of complex and expensive micro-nano-processing technology, compared with the existing SRG technology, the preparation cost can be reduced by 60%. It is expected to promote the large-scale commercial production and popularization of the application of AR glasses.Third, it is light and comfortable to wear.'Skylark' weighs only 45 grams, and the wearing process is more comfortable and senseless, which greatly improves the convenience and smoothness of the user's control, and brings an efficient, intelligent and immersive AR experience to the user." Yuning Zhang said.
"Skylark" represents a new display paradigm.
How will it affect our lives in the future?
Zhang Yuning gave us a picture of longing: "For example, you watch TV at home, where you want to sit down to see can be; look at the phone is also, do not need to take the phone out of your pocket, it can be presented in front of your eyes, and even the size of the screen near and far can be controlled; driving is also, the car's instrument panel can be grafted to the glasses, directly presented in your eyes! In short, the original display can carry the function, the future AI glasses can carry!"
