Optimizing your experiences (Android only)
You don’t need to scan a VR QR code to enjoy virtual reality with Freefly VR, but for Android users who desire an optimized experience, there is a picture you can scan to improve the quality of the experience. First of all, you need to download the Google Cardboard app to your phone, just as you would an other app. This link takes you there. Next, try a virtual reality app. For the purposes of this guide, download the educational game InMind VR.
What is a virtual reality QR code used for?
VR QR codes can optimise the experience by correctly distorting the image playing on your phone to match the distortion of the Freefly VR lenses.
Aside from comfort, the biggest difference between mobile phone based VR headsets are the lenses, and how they are configured within the headset. The way the lenses distorts the images varies widely between headset manufacturers.
Because of this, Google introduced QR codes to distort the image of the VR experience to correctly match the distortion of each headset's lenses.
You don't need to worry about generating a QR code - most VR companies supply their own, but if you are a techy, you can create your own via the Google Profile Generator
Most VR experiences are barrel distorted. Barrel distortion has been used for over 20 years in virtual reality because it more closely matches the way the human eye sees the world. However, looking at a barrel distorted image with the naked eye looks odd, so it is the job of the lenses to correct the geometry. The QR code tells the phone how to distort the image so it fits the distortion of the Freefly VR lenses.
Once you have followed the instructions in the video, we offer three QR codes for you to try and reach a preference.
