We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
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.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. 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. And always feel free to hit us up on Twitter @MxdRealityDev.
Using the hololens on a moving platform
We have a very specific use case for the hololens that involves using it onboard of a ship while it is moving. From my testing so far (just in a car), it seems the device loses it's bearings, as it were, when the platform moves but the user does not.
From what I can determine, this is because of an inability for the 3D camera sensors to reconcile with what the IMU reports (cameras report stationary, but IMU says the user is moving). On board of a large ship, the "world" will indeed seem stationary to the cameras, but the IMU will still pick up inertial movement of the ship.
Is there any way around this? Am I correct in my assumption as to the source of the problem? Any chance this can be handled in a future update?
One solution I can see would be to modify the IMU data with a stream from a second IMU that is fixed the the ship, so that the ship position can be "subtracted" from the user position and thus the hololens only sees the motion of the user relative to the ship.
I know the official word is that the device is intended to be used indoors, but this is a big issue for us (and technically, inside a ship is still "indoors".)
Any insight appreciated... thanks.
