I haven't looked over this application in detail, but I can certainly give you my thoughts!
So, the way patent applications work, is you have a written description (called the Specification), the bulk of which is called the Detailed Description. This is where you find the in depth discussion of how the invention works, what it can do, what's the best way to reproduce it, how to use it, etc.
Then you have the legally crucial element- the Claims. The Claims are what the inventor is saying should belong to them for the term of the patent (20 years from filing in the US). So, when someone is sued for infringing a patent, they are accused of infringing on the description of the invention that's shown in the Claims.
A lot of big companies (Nintendo included I'm guessing) will file a patent which a huge Specification that covers a large number of different Embodiments (or forms that the invention can take). In these cases the inventor can file several different Applications which each share a large portion of the same Specification, but have completely different Claims.
For Application 14/805,736 specifically, which is the App no. for the case you linked, the Claims seem to be drawn to a camera on a handheld gaming device which can sense the user's position in order to display different types of information on the screen. Figures 17A and 17B show a situation where the screen displays a pyramid shaped object, and if the user moves their head to one side, then the image on the screen will turn as if the pyramid was physically coming out of the screen. So, in essence, a more interactive 3D, or I suppose a simulated hologram.
But that's just one of the many features discussed in the Specification for this Application. There will likely be other Applications filed in the future (if not already) that have more or less the same Specification and same figures, but the Claims are drawn to completely different features, like the LAN or NFC features shown in some of the figures.
Hope that helps!
