Short of finding a secluded corner or speaking in a whisper, there is one more way to escape into your own world although you travel. Some developers have come out with video glasses that enable you to watch videos anywhere you go.

A lot of video glasses are portable and connect to video iPods.


?How do these gadgets provide you with the illusion of sitting in front of a big-screen tv? The patents filed for several of these cutting-edge video glasses give us some beneficial insight.


The displays usually use liquid crystal displays (LCDs) or organic light emitting diodes (OLEDs). A lens magnifies these tiny displays so viewers really feel as if they’re sitting in front of a significant screen. Video glasses come equipped with audio equipment, often inside the type of earbud headphones that hang from the headpiece. A battery pack and media player connect to the glasses by way of wires.


The mechanics of video glasses are designed to capitalize on an remarkable function of our vision perception. Most video glasses display two images — one for every individual eye. When aligned correctly Wholesale Hockey Hoodies , video glasses enable our brains to make a composite image of the two displays. This allows us to sense depth. Putting together images to form 1 3-D image in our brain is known as stereopsis.


The advanced video glasses that strive for this 3-D illusion are binocular. Simpler, two-dimensional varieties are biocular. Whereas binocular glasses display two slightly various images to each and every eye, biocular head-mounted displays (HMDs) project 1 image which is observed by both eyes. Hybrids, which use a combination of binocular and biocular techniques Wholesale Hockey Jerseys , split the video image into two parts. From these parts, your brain creates a single composite image.

Our eyes have a natural horizontal FOV of about 180 degrees, but video glasses supply smaller FOVs (ranging in the 20s, usually). This is partly because of the technology employed to film videos in the 1st place .
