[An error may occur in Unity.]

Thank you for your reply.

It is not always reproduced. It will be reproduced occasionally.

The test scenario is as follows.
1. Scene A starts with the target displayed in front of the user.
2. The user looks at the target for 1 second (scene A).
3. Move to scene B with 10 objects displayed at random positions.
4. Success when the user finds the target from within the object and gazes at the target for 1 second (Scene B).
5. Repeat 1 ~ 4. 10 times.

[An error may occur in Unity.]

Hello!

I am developing with Unity2017.4.34f1 using Vive pro eye.
In the project I developed, scene transitions occur frequently, but at that time, an error [[SRanipal] Initial Eye: DEVICE_NOT_FOUND] occurs and the eye tracking function stops responding.

Please help me if you know the cause or solution of this problem. Thank you!

[The calibration result is strange.]

Hi

In addition to the above, I also tried a few.

・ SRanipal upgrade and downgrade

・ Reinstall SteamVR and SRanipal

Doing these things did not cure the calibration screen, so I think the SteamVR update is probably the problem.
However, I don't know how to downgrade SteamVR, so I can't try it.

[The calibration result is strange.]

Thank you for reply!

Yes, sometimes the top dot flickers.

Is it due to Steam updates? If so, will the old version of Steam solve it?

[The calibration result is strange.]

Help me!

The line of sight is no longer displayed on the screen after calibration is complete. Also, it was displayed without problems until last week.

If anyone knows a solution or cause, please let me know. Thank you.

Thank you for answering.

[Is it impossible to get eye images with an infrared camera?]

Hello.

Is it possible to display the eyes of the user wearing Vive pro eye as an infrared image on the monitor?

It will be helpful if someone tells me.
