Room Separation
Hi,
I'm new to HoloLens, and before playing with it and doing something more serious with it, I need to know something.
I have a project where I need to know which room I am, and separate each room to display different stuff in each one (let's say I have a living room, a bedroom, and outside home), is there a way in HoloLens to know that, for example, I started outside, entered the living room (room 1) and moved to bedroom (room 2) and know which room I am at the moment?

You can use gaze to detect that you are gazing upon a game object, and based on which room that game object is in, you could detect. But if the user gazed upon an object in a different room, it would be inaccurate.
I think it could also be done with pixel light detection, if you placed a light source with limited range in each room and upon detecting light from that source on a pixel that travels with the camera would know the user is close enough to be in the room.
Okay, so HoloLens won't give me this info by itself, I need to come up with something to mark each room. The light idea, I imagine could not be done as I cannot ensure the same room for every user (as it is a project for a firefighting scenario, different places might be used), so maybe ask the user to pinpoint objects in a scene, or maybe capture the room surface and mark it before starting training?
Hi Zharramadar. Scanning the rooms beforehand seems like a worthwhile approach, especially for a training application where you want a consistent and repeatable environment for assessing improvement.
Given that, one possible approach that should be relatively easy to prototype would be:
Simplest place to start would be to use SurfaceMeshesToPlanes in the HoloToolkit.
Good luck!
