Holographic lenses

So, we have all the input parts. Now, we also need to get data out to the user. The most obvious part of this is the way the HoloLens displays the images. Since the HoloLens is a see-through device, meaning that it is transparent, the device only needs to provide you with the graphics the game or application needs to perform. This is done by the use of what Microsoft calls Holographic lenses. These two lenses are basically two tiny transparent computer screens in front of your eyes, where the device projects its images. Yes, I said transparent screens; these tiny computer screens are almost completely see-through. The resolution of the screens is 1268 x 720 pixels per eye, which seems low, but in reality is enough to generate good-looking graphics. Remember that the screens are tiny, so a lot more pixels will not make a lot of difference. In my experience, the graphics are just great and I noted that this low resolution was not a problem.
