Not easily. Samsung has something like this, which attempts the minimal task of "see if you're looking at the screen" to prevent dimming while you read. It's.

Not easily. Samsung has something like this, which attempts the minimal task of "see if you're looking at the screen" to prevent dimming while you read. It's... not good. Not even passable, in my experience.
That task should be achievable, but anything fancier - even positioning a dot - is probably still a tall order with that single camera.
- charlesdm 10y agoThe hardware based IR solutions (e.g. Tobii) tend to work really well, though. Is it a matter of not having figured out yet how we could achieve similar results using just a webcam image?
- mattkrause 10y agoThe IR part is the key--webcams have IR-cut filters to keep the visible-spectrum picture from looking crappy.
