Dizziness-Free AR Optic Lens To Be Unveiled By LetinAR at CES 2018

LetinAR Co., Ltd. will be introducing its Augmented Reality (AR) glasses at the upcoming CES 2018 exhibition. People can expect to be dizziness-free, even after prolonged use of the AR glasses.

LetinAR Co., Ltd. ("LetinAR" or "The company"), a professional AR technology company, is anticipating the CES 2018 exhibition of a groundbreaking AR optical solution, and its smart glasses armed with it.

Humans perceive the distance to the object they see with a comprehensive analysis in the brain, in which it takes into account various information such as the two images projected on the retinas, visual angles and the thickness of eye lens. Conventional 3DTV, VR and AR devices can express only fixed distance to a virtual object in 3D, and it induces early fatigue and nausea to the user in a brief period of watching.

The company independently developed the Pin-Mirror technology, capable of showing a sharp virtual object image on short distance using very small reflectors. While other AR head-mounted display (HMD) devices can only 'display' virtual objects over a meter away, the Pin-Mirror Lens enables simultaneous display and 'interaction' with a sharp virtual object 25cm away from the eyes without feeling dizzy. 

The Pin Mirror Lens also provides a wide field of view (FOV) of over 70° and a clear expression of full color without chromatic aberration. LetinAR CEO Jaehyeok Kim says, "We currently provide a 1280 x 720 resolution for each eye because of the limitations in micro-display, but users will still enjoy the Pin-Mirror AR comfortably with no decline in quality after the launch of high resolution display, 4K or more."

Furthermore, LetinAR succeeded in the injection molding of high refractive index plastic into ultra-precision Pin-Mirror Lens, laying the foundation to mass production for the future AR market.

The company also plans to show its AR smart glasses equipped with Pin-Mirror Lens. The new smart glasses look very similar to ordinary glasses with no protruding lens, and they only weigh 99 grams. Therefore, users can work, play games or sports, and enjoy other everyday activities with comfort while wearing the glasses.

Visitors can experience various real-life AR applications at CES, including multilingual simultaneous interpretation to over 100 languages provided as subtitles on the smart glasses, connected with NAVER and Google translation services.
