[Question about EyeData]

Hi @Assc:

(#1) The data `gaze_origin_mm` represents to your eye location and the origin point is in the middle of your HMD. So if you want to know which point you are looking at, you should use the data: `gaze_direction_normalized`

(#2) Assume both SINGLE_EYE_DATA_GAZE_ORIGIN_VALIDITY and SINGLE_EYE_DATA_GAZE_DIRECTION_VALIDITY are valid, others are invalid. The `eye_data_validata_bit_mask` will be 3 (decimal integer). So the GetValidity() function will offset according to given parameter to check it's validity.

(#3) We are not support `convergence_distance_mm` now.

[SRanipal not listed in Unreal plugins]

Hi @GestureLab

It's weird since after you rebuild the plugin, it should work.

Can you help me check some details?

1. Check the Plugin's binary files, it's in: Plugins/SRanipal/Binaries/Win64/. The binary files should include 5 dlls and 1 lib file.

2. Check the OS you are currently use, it should be Win10 64bit.

3. You can either try some work around. Open the file: Plugins/SRanipal/SRanipal.uplugin and change the "Installed": false to "Installed": true.

Hi @GestureLab

 

Can you let me know which version's Unreal Engine are you using?

In my Unreal 4.18.3, the plugin shows up in the list correctly after I copy the Plugin folder into a new project.

Hi @AirMouse

Have you try the sample scene in our SDK? Does it broke too?

[Update 1.1.2.0 eyelids getting stuck???]

Hi @AirMouse

 

Could you let me know which version of SDK are you using now?

You can check it from SRanipal.dll's detail page.

I have test SR_Runtime 1.1.2.0 with both SDK 1.1.0.1 and 1.1.2.0 and they all works as expected.

 

Sincerely

[Eye expression data]

Hi imarin:

 

 

According to your symptom, perhaps the problem is on your framework GameObject setting.

The SRanipalEyeFramework game object has an option to choose enable which version's framework.

I have test with the latest SDK,  the prefab's default enable version will be set to "Version1". So you can get proper value in original version eye framework.

You can checkout the "Enable Eye Version" first in the game object's inspector.

 

If it still not working, maybe you can check if our sample scene: EyeSample_v2 can works properly or not.

If the sample is not working either, please let me know. Thanks!

 

Best Regards,

Jason

 

[Eye expression data]

Hi imarin:

 

First, you can check you SR_Runtime version by right click the system tray icon, we support eye expression since version 1.1.0.1.

Second, you can check you are initial the right eye tracking version in Unity or Unreal. (SRanipal_Eye_v2)

The origin eye tracking do not support eye expression.
