HoloLens - distance tracking accuracy problem
We are testing our app on the HoloLens and found a huge issue with the distance tracking. The error margin is 25%-40% (for every 10 m walked, HoloLens will be off by 2.5-4M) under the ideal light conditions. The device failed to track the rotation accurately too - a 180d turn will cause the device to be off by nearly 10d.
For comparison, iPhone 6s with a single camera had the error margin of 2% during the same test and virtually no issues with tracking rotation.
The same app, running on the same device used to be a lot more stable and accurate just 6 months ago. Did the recent HoloLens update introduce these problems? Also, what is the remedy? Spacial anchoring has no effect.
