I think that’s a poor approach. While you end up with gaze more in the center of the display, you don’t always have a face directly centered. This alleviates some of the problem, but doesn’t remove it.
A better approach that I’ve always wanted is to have four cameras on the corners of the display that generate a real time photogrametric projection of your face. This would mean not only would your camera view be dead center, it’d be center no matter where you were looking on the screen. Much better especially in situations where there are multiple people in a meeting. You could even have different streams for each meaning to the other attendees it appeared as if you were looking directly at them only when you actually were.

- Zanni 6y agoThis is surprisingly difficult with a device like an iPad or smartphone in landscape where the camera is off to one side. Even knowing where the camera is, the image of the person on your screen that you're talking to tends to pull your gaze back. You can do it; it's just an effort.

- crazygringo 6y agoIt would be relatively trivial to automatically keep the face of the person you're talking to centered around the webcam using face detection. As a person moves in frame, your computer will "pan" to keep them centered. Four cameras is intriguing, but also expensive and complicated, and will probably have a very rough time with things like eyelashes, edges of hair, different patterns of reflections on the eyeballs, different glare from lighting, etc. Realistic photogrammetry is really hard in practice, and runs the risk of being really uncanny valley.
- namibj 6y agoPhotogrammetry doesn't yet properly handle non-diffuse surfaces for the most part. There are some experiments, but they're way behind in other aspects. And I'm not even talking real-time. So, yeah, uncanny valley or teleprompter it is.
