How VR Happens by Jivom Sharavanah

So how does VR happen?

Many things are involved with VR. First off, measurements need to be taken of six vital things in order for the screens you see to look real.

Image resolution, the number of pixels in an image, and field of view, the amount of the image you can see, need to be decided. Then the refresh rate, the rate in hertz at which the screen refreshes, and motion delays need to be calculated. Not to mention that pixel persistence, the amount of time the display is lit rather than dark per frame, has to be taken account of and audio/video synchronization, connecting the audio to the video, should be sorted out.

A VR headset has a setup of two screens, one for each eye. By looking through two lenses (screens), it gives users a sense of depth, stereoscopic display, explained in the VR development section above.

The VR headset contains motion sensors to detect the user’s motion by measuring positions and angles. For example, if the user turns to the left, then he or she may see a store. But if the user turns to the right, then he or she may see a library. The images are in place the whole time. The user is just changing his or her perspective relative to space.

Some VR headsets have an infrared controller which monitors the direction of your eyes inside a virtual environment. With this, users receive an even deeper and realistic field of view. VR headsets also include auditory technology, like the Frights Nightmare Roller Coaster, to stimulate your other senses. From there, other VR technology can impact your sense of smell, touch, and taste.

VR is a very STEM influenced technology, and you can try your hand at VR here at ACL. To learn more about how VR works in depth, click the source https://thinkmobiles.com/blog/what-is-vr/ and watch a cool interactive video that covers the facts.
