Dear  @原田空来  @PheonixLab @Jad  @Nermeen  @idontwantthis

My eye tracker suddenly doesn't work, could you explain me more in detail how did you fix the problem? I ran into the same problem. Thank you very much. I am frustrating also.

From guide document, SRanipal Runtime  only support  Windows.

 How could we develop  eye track features for  Vive Focus Plus? Do we need some native runtime lib  for Vive Focus Plus device?

There is eye track components for Vive Focus Plus:


 Thanks a lot.

I must be missing it, but where can I find the SRanipal Unity API documentation?

Couldn't find it in this thread, nor in the FAQ or in the downloaded zip file. Tried googling it, but I keep coming back to the same pages.

@jboss You can find the documentation included with the SDK zip file.

Eye Tracking SDK (SRanipal) Documentation can be found in these files (html & PDF):
"SRanipal_SDK_1.1.0.1.zip\SRanipal_SDK_1.1.0.1\02_Unity\Document\Eye\Getting Started with SRanipal in Unity Eye.pdf"

I was having problems with calibration so I decided to uninstalled and re-install but now when I re-install the VIVE_SRanipalInstaller won't let me repair or install I'm not sure what the fix to this is. These are the screen shots of when I try to either repair or remove.
