The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
Hololens user position
If I use the hololens for a Mixed reality application, I need to know not only the relative position of holograms to the hololens but also the relative position of things in reality to the hololens. How can you do that? (I understand that it does not have a GPS and that it wouldn't be effective anyway for indoors)
As an example of what I want to do let's say I have a layout of an apartment (living room, toilet, kitchen) and I want to navigate with my hololens. To do that I would need to know the relative position of things but the problem is that the user experience does not start exactly at the same point every time right?
