In addition to the HoloLens Device Portal (see part 1), another option is using the UAP HoloLens companion app which you can install from the store. I think this is a little more end-user friendly, and perhaps a little less developer focused. It exposes a subset of the same functionality.
Once you install it, you connect more or less in the same manner; I think most people will like the live streaming option. There is a bit of latency between the device and what is shown, but that could be somewhat because of our (possibly crappy) wireless which was overloaded with many folks at work.
Once you login, you see a lot of the same information as you saw in Part 1.
You can see the Live stream as shown here; and what might not be obvious that it is both sound and video which is streamed. In this screenshot you can see my (work) login screen, with the password login being a Hologram. Here it is ‘floating’ over the window, and you can see a flavor of the mixed reality.
All in all, this is a little more polished and end-user friendly. Useful when demo’ing the mixed reality solutions you are building.
