Leap hands frequently upside down, tried reverse orientation + auto orient

[camillew]

Hi there

This is a fairly urgent issue as we're deploying a large-scale consumer VR project soon.

We have a LeapMotion mounted onto our Vive Pro headsets, in a fixed position and fixed orientation.

Constantly on startup of our Unity builds, the Leap hands do not appear when the user holds up their hands. When this happens they start showing up when the user holds their hands upside down. The only way to fix it is either to replug the Leap Motion, or go into the control panel and click Reverse Orientation. Both options fix it immediately.

I have tried with Auto Orient both ticked and unticked, but it always seems to reset very regularly where it breaks and requires the orientation to flip again.

Help is very appreciated - how can I get the hands to stay in a fixed orientation and always work??

Alternatively - can I restart the Leap service from within Unity to force a restart which hopefully fixes the orientation?

Could you provide a video of the issue occurring?

What software version are you running?

Check the following directories and let me know if you see a config.json file in both:
C:\ProgramData\Leap Motion
C:\Users\USERNAME\AppData\Roaming\Leap Motion

If you do see the files, open up services.msc and stop "leap service" and quit out of the Leap Motion Control Panel. Then, delete the config.json files, reboot your computer, and try enabling auto-orient tracking to see if the setting persists through another system reboot.

We'd also love to hear more about the project you're working on. Could you provide some details on what you're doing? If you don't wish to share it publicly, you can PM me as well.

Hi jhung

Thanks for your reply. We found something that seems to have worked in the meantime.

We physically flipped the LeapMotion so that the green light is on the bottom, as I saw in another post. This means even if the orientation resets then it's already in its "natural" orientation so it should work. I have not noticed any issues since doing this and have tried many times. The only minor downside to this is that the cable is now on the other side and does not line up with the Vive Pro's connector cable, so we have cables coming from both sides of the headset now.

After seeing your post I checked and both config files are there, however I would note that the one in the user's folder was missing the ""image_processing_flipped": false line (it was present in the ProgramData config). Not sure if that makes any difference. I have copied that line into the User config as well just in case.

Will let you know if we encounter any issues after this but I won't be able to test your solution and provide you with a video until we are done with our demos this week.

Orion software version 4.0.0+52173
Firmware revision 1.7.0

I will send you a PM shortly with more info on the project.

Thanks!

If you do see the files, open up services.msc and stop "leap service" and quit out of the Leap Motion Control Panel. Then, delete the config.json files, reboot your computer, and try enabling auto-orient tracking to see if the setting persists through another system reboot.

Did you try these steps to see if the auto-orient option remains enabled through a reboot? You need to have the service stopped as well as the Leap control panel closed to modify or manually place configs, otherwise the changes dont take.
Feel free to report back with the results at your convenience.

I get this pretty regularly too. My settings are always the same when I open the app, but the tracking is upside down anyway. I hit Reverse Orientation and go on with my life. I have my device mounted with the green light up. Next time my mounting solution (which mostly involves scotch tape) comes off, I'll try flipping it over. It would be great if the orientation didn't keep changing though.
