United States (Lilamax) - Facebook patented technology that would watch you through your phone or computer’s front-facing camera, and see how you react to content.
Now, just because Facebook patented it-that doesn’t mean it will actually happen.
The Daily Dot says the system would just look at you to see what you think. Then, just as Facebook's algorithm does now, it would decide what to serve up to you next based on your mood.
It could also put up filters of hearts or tears or whatever to match your feelings.
