Fb just lately displayed a slim VR (Digital Actuality) idea glasses whose look is extra like a sun shades. The present VR gadgets are nonetheless comparatively “cumbersome”. This makes many individuals really feel very uncomfortable when carrying them for a very long time. As proven within the picture, the idea ultra-thin VR idea glasses from Fb may be very skinny and light-weight. In line with Fb, the glasses use holographic optics and different applied sciences. The thickness of this glasses is lower than 9 mm. Nonetheless, that is solely an idea design for now. Fb made it clear that its present work is purely research-oriented.
Fb’s ultra-thin VR idea glasses makes use of a holographic lens
As an alternative of the same old cumbersome lens, Fb will use a skinny movie that achieves focusing by holographic optics. In line with Fb, this analysis may “ship a subject of view corresponding to at present’s VR headsets utilizing solely a skinny movie for a thickness of lower than 9 mm”. Excluding the precise laser supply, the entire weight of the ultra-thin VR idea glasses is simply 18 grams. In line with the analysis, Fb stated “for our green-only sunglasses-like prototype, we measured an general most subject of view of roughly 92◦ ×69◦,”.
As of now, the one sensible illumination supply is lasers at particular angles and wavelengths. It is because holographic components disperse gentle. Moreover, the ultra-thin VR idea glasses prototype can solely display inexperienced color. Which means it’s monochrome for now. With additional engineering, Fb believes that it will probably deliver multi-colour to the headset. We all know that laser gentle (color gamut) delivers wider vary of colors than LCD. The truth is, its vary of colors can be barely wider than OLED. Thus, if it may be utilized in a head-worn system, will probably be a significant achievement.
Current-day VR headsets are fairly cumbersome, why?
The most important motive for the scale and bulkinesses of present-day VR headset is its optical design. Firstly, the headset must amplify the display over a large FoV (Area of View). Additionally, it should focus it over a viewable distance. This requires an enormous and thick lens in addition to a big hole within the design. In fact, your entire system will want housing. Properly, placing all these collectively, probably the most minimal design will exceed 300 grams in weight. Whenever you now contemplate some standalone headsets that require a battery, cell chips, and different options, the load additional will increase.
A couple of firms are already working to get the load down. If the load of VR headsets can get right down to 200 grams, will probably be extra consumer pleasant. Carrying a 500 grams headset in your head for one hour may be very removed from comfy.
