Using ML2 in lying position

Hardware Troubleshooting
1

Dear community,

I am currently using the ML2 system in a supine (lying) position setup, specifically within a radiology scanner that has a relatively small bore. I’ve encountered two issues:

  1. The main menu only appears in the horizontal region, which limits visibility and interaction when the subject is lying down.
  2. The system frequently loses tracking in this configuration. In this case, I don’t actually care the world camera.

Is there a recommended configuration or adjustment to improve menu placement and tracking stability in the supine position, particularly within a constrained scanner environment?

I appreciate your guidance and thank you in advance for your help.

Hi @wangzipai96 currently we do not support this use case. We do not support disabling tracking on the headset so the headset must be able to position itself in the world at all times. Since the world cameras that track the environment are mounted at the front and sides of the headset. The challenge is trying to track the user’s movement as they lay down on the ground facing a mostly featureless/ textureless surface.

While this functionality is not on our roadmap, I have submitted your feedback to our voice of customer team.

Unfortunately, this type of functionality is not on our roadmap. Your feedback was shared with the voice of customer team however we cannot commit to the requested changes. Perhaps as a workaround you could add more feature points on the ceiling and walls and try to make sure that the cameras are not obstructed.

By mistake, I deleted my previous post, so I am posting it again.
We have purchased about 10 ML2 units, and we need to be able to use them in lying position as mentioned in this post. We need to disable tracking on the headset using front-facing cameras, otherwise we cannot proceed with our experiments. Can we request for this feature to be added? The workaround suggested won’t work because we will use the ML2 inside a medical imaging scanner’s bore and will have limited depth-of-view (DOV). However, if we can turn off the tracking feature, the ML2 can function correctly without interruptions.

Unfortunately, I do not have any other suggestions. It does sound like the device tracking would need to be disabled to work in your use case. I have shared your feedback but the magic leap 2 does not have this type of functionality. It’s core systems assume that the user’s head pose is tracked.

Sorry to hear that you ran into this problem.
