Have you ever thought about Virtual Reality, well you must have listened about it in Sci-fi movies,
Now have you ever thought how to get your hands on this advance technology.
Most of us don't know that one can get it for 30$ , yes really for 30$ and know what, you can experience it on your smartphone.
Its commonly known as VR headsets.
Today many well known companies are working on it and call it by different names such as,
- FACEBOOK [ Oculus rift]
- GOOGLE [Google cardboard]
- SAMSUNG[gear vr]
- SONY [PS VR] and almost 50 more.
Want to know how it actually works???
Well if you thought that vr works on a technology far advance than your thoughts , then dont worry
VR actually works on two simple concepts
1. Creating a wide view
2. Head tracking
VR headsets use either two feeds sent to one display or two LCD displays, one per eye. There are also lenses which are placed between your eyes and the pixels which is why the devices are often called goggles. In some instances, these can be adjusted to match the distance between your eyes which varies from person to person.
These lenses focus and reshape the picture for each eye and create a stereoscopic 3D image by angling the two 2D images to mimic how each of our two eyes views the world ever-so-slightly differently. Try closing one eye then the other to see individual objects dance about from side to side and you get the idea behind this.
One important way VR headsets can increase immersion is to increase the field of view i.e. how wide the picture is. A 360 degree display would be too expensive and unnecessary. Most high-end headsets make do with 100 or 110 degree field of view which is wide enough to do the trick. Head tracking
Head tracking means that when you wear a VR headset, the picture in front of you shifts as you look up, down and side to side or angle your head. A system called 6DoF (six degrees of freedom) plots your head in terms of your x, y and z axis to measure head movements forward and backwards, side to side and shoulder to shoulder, otherwise known as pitch, yaw and roll.
It actually uses , your smartphone sensors like
Gyroscope- To measure angular velocity for heasmd rotation
Accelorometer- To measure linear velocity for head movement
Magnetic sensor- To measure your current magnetic direction
Orientation sensor- To measure your head orientation.
TO VIEW 360˚ alligned video, your phone must support gyroscope.
WHERE TO BUY IT???
Well there are a tons of VR headsets in market .
Ranging from Rs 100 to Rs 15000
Most companies are now bringing up pre defined VR headsets for various smartphone models, but there are a tons of universal VR headsets for smartphones with screen sizes [ 3.5 inches to 6.5 inches]
