HoloLens shell is the MR world that contrives the immersive experience with holograms and the real world. Whatever we see through the HoloLens appears through the HoloLens shell. At the beginning, the shell launches with the start screen, similar to the one for any system running on Windows 10.
The start screen is the first point of interaction with other holograms. To launch a holographic app, open up the Settings options for HoloLens.
The Start menu of HoloLens consists of basic system information, including time, Wi-Fi connection status, battery status, and many more. All this information is pinned up on the front view along with all other apps, which we can navigate through. It also consists of buttons to capture photos and MR video along with options to invoke.
