This is a frame from a video taken using the HTC Vive (it's from the user's perspective of a game I developed in Unity) I've overlaid those boxes in paint.
I'm trying to determine which character the person is looking at (assuming the white box is where they user is focusing)
I know this can be done in Unity without the need for a video, but I want to know if the video can be analyzed using something like OpenCV to detect how long each character faces is in the white box. I just made this in paint to get the idea across, the parameters aren't to scale or anything, I just have no idea where to start with a concept like this apart from OpenCV.
But to summarize, can I use OpenCV to detect how long each face is in the centre of the screen? i.e. How long the user looked at each character.
