If you connect the glasses to your computer you get a fixed screen in front of your eyes (like those display glasses back in the day that promised to give you a huge screen), which is fine for video viewing but if you want to use it for productivity you want to be able to look at certain parts of your screen vs. straining your eyes to glimpse the edges.

That's where this comes in, it allows you to look around the virtual screen with the added bonus that you can connect it to almost anything and behave the same not just your PC
