Take your time reading through the Guide and consider common issues that arise even in the most well-designed VR experiences. This will prepare you for further content in this course.
In the exercises below, answer our questions by referring to the Guide. In the second part of the assignment, you will use your VR Best Practices knowledge to critically evaluate some VR experiences we have set up for you. Therefore, ensure you read the Oculus Best Practices Guide carefully.

Note: Make sure you always use your QR code generated in previous homework for the most comfortable experience, both in apps and on YouTube. To do this, every time your phone is in split screen VR mode, click on the gear settings icon and scan the saved QR code for each of your newly downloaded experiences.
For High-End HMD Users: If you own a high-end HMD, you may also download the following VR experiences from the Meta Store. To download and run these experiences on your headset, you need to find them in the Oculus Application’s library and install them. Then you can use these experiences to answer some of the questions below where appropriately.
Notice, that you still need to download the Carboard experiences on your phone and review them as well. This is an opportunity for you to compare the high-end HMD experiences with the Cardboard ones.
