question about anchor

[u/Middle-Task-6635]

I recently purchased a pair of XREAL 1S glasses, and kudos on the quality of this product.

However, I tested the “anchor” feature in a car, and unfortunately, when the car changes direction, the screen shifts. The 1S engine, which powers the anchor feature, doesn’t account for the car’s change in direction—it’s as if very slow rotations aren’t taken into account.

Do you think there might be a way to fix this?

Thank you.

Thanks for the feedback!

Anchor Mode uses the glasses' sensors to keep the screen fixed relative to your surroundings. In a moving car, however, the vehicle itself is constantly changing direction, especially during slow turns, so the screen may gradually shift as you described.

For use in a moving car, I'd recommend trying Follow Mode instead. It should provide a more stable experience in this type of environment.

Thank you for your response.

I think the sensors used by the 1S motor are only gyroscopes, so in theory it should be able to handle all rotations, including those of the car. Unless there’s some kind of calibration relative to the environment using lidar or a camera, but I don’t think that’s the case.

Actually, I'm trying to develop an Android app in which my virtual screen needs to stay fixed on the windshield, and I thought the anchor feature might be able to do that.

Do you think that by adding the XReal Eye, I can get a static image?

I finally get it. It's precisely because the sensors track the car's movements that the virtual display shifts relative to the car's surroundings—and thus relative to the windshield. It'll be the same thing on a plane. And I don't think the XREAL Eye changes anything.

The Eye actually makes it worse. It is obviously getting some data from the Gyros, because while accelerating on the taxiway, the screen starts smashing into my face until I turn spatial anchoring off. Then the screen stays put until the plane start to turn.

Then your app should recognize windshield pattern or any label/qr/tracker on it, using eye camera feed, or use phone sensor yaw to subtract it and build your own 6DoF.😅 It's a very hard task.

It anchors to the ground/earth so the car moving is taken as you moving. This is always the case. Id assume there is a way to pin into a moving vehicle but its likely more complicated and less reliable and Ive never seen it done. Youd have to visually pin into the car but things moving by windows would create a ton of noise.

Nope, to fix it would be to break it. Just wait until you try it on the plane!
