Eye tracking and Lip tracking at the same time?


Recommended Posts

I am trying to use both eye and lip tracking together in my Unity scene. I can not get them to work together at all.

If I enable both SRanipal Eye Framework and SRanipal Lip Framework in my scene then only the eye tracking works. Once I destroy the SRanipal Eye Framework object then the lip tracking starts working.

 

Is it even possible to use both Eye and Lip tracking together at the same time?

If not then can somebody please explain why would it not be possible?

       

 

SDK-v1.3.3.0

Runtime v1.3.1.1

Eye camera version 2.41.0-942e3e4

Lip camera version 50100

Unity version 2019.4.23f1

 

Thank you

I just tried updating the Runtime to v1.3.2.0 but get exactly the same issue.

 

So I am still unable to use both my eye tracker and face tracker at the same time, Please can someone help me figure this out !!

I tried testing FaceGym and there was no face tracking available.

But what's really strange is that when I connect the USB cable from the Linkbox into a USB2.0 port the camera is detected and almost works (it is very jumpy and less than 1fps) but it works!!!

When I move back to USB3.0 port it is not detected.

 

I have tested using onboard USB3.0 ports and a PCIE USB3.0 card (intel chipset) and both the lip camera is not detected.

 

Why would USB 2.0 work better than a USB 3.0 ? Is there anything I can do??

Just picked up a lip tracker today, so I can't say I've tried much yet, but I'm having the same problem so far. Interested to see if anyone has advice. Seems strange that they wouldn't play nicely together.

I managed to get them both working using the Vive Wireless adapter, however the latency is so bad i can barely walk much less enjoy any of these new extremely expensive pieces of hardware.

I can't say for sure but after the weeks of effort I have spent trying to make this work and it simply is broken - most users would just give up I'm sure and post bad reviews.

So here's my review:

  • The Vive lip tracker is really good
  • The Vive eye tracking is really good
  • Vive lip tracker + Vive eye tracker is absolutely horrid .

I'm having the same problem.
When I put the ready-made prefabricated SRanipal Eye Framework and SRanipal Lip Framework in the same scene, the lips do not move.

Is there any way to solve this?

I changed the port from USB 2.0 to USB 3.0 and reconnected it again and again, and that solved the problem.
I don't know what caused the problem, but it may be that the driver was installed correctly.

Hmmm ......
