Check if user is looking at a specific target using Eye tracking SRanipal in Unity

[Mo.Issa]

Hello,

I am trying to build a VR application using Unity 2019.4.1 and Vive Eye Pro. 

Assume I have a "red" sphere in the scene, I want to check when the user looks at the sphere and change its color to green.

Using the following libraries ViveSR.anipal.Eye, ViveSR.anipal, ViveSR

I can read and check the data eyeData.verbose_data including gaze direction, gaze origin, eye openness and many more.

I would appreciate any guidance and support to implement the example explained above. 

Thanks.
