How Virtual Reality Glasses Work?

Everybody has tried one of the virtual reality glasses these days, and they are becoming mainstream as time goes by, experiences and games get launched and the technology gets cheaper.

They are becoming better, lighter, easier to wear and more.

Some of them are video only, they can be just HMD, while others have head tracking, audio or other features.

3D Goggles already displayed 2 different images, normally one in blue and the other in red, but now with VR these glasses simulate the two similar viewpoints each of our two eyes give us, adding that depth component we need in order to enjoy a Virtual Reality experience.

If you want to look upon this phenomenon in a more in-depth way, you should search for “CAVE Environments”.

Then you have some higher-end Virtual Reality glasses – high-end today, probably mainstream tomorrow – that have head tracking hardware and features, which send signals to the device to adjust the view according to the way the wearer of the goggles moves around. This provides you with a fully immersive experience that simulates how you turn your head around in the “Real World”.

Thus, you now have access to a way to enjoy media not only as a 2D watcher but as someone inside a 3D environment, with depth perception, 3D images, and more.

This is great for the entertainment industry, but also for any other industry out there, being it industrial, mechanical, fitness, and so on… the ways to use VR to improve our lives are tremendous in variety and number, usually limited only by creativity and hardware limitations which still pose a bit of an obstacle since this technology is only now reaching these levels of development.

This is how virtual reality glasses work, and if you experience even a slight lag or latency, the illusion will suffer greatly or break altogether.

If the head tracking stops working and you move your head only to see a still image, not only does the immersion break but you’ll get sick to your stomach due to VR Sickness.
