I find I use my Poral with my parents a lot to do virtual tech support. They spend a lot of time turning their phones around to the camera, and Portal zooming around to their face, or someone else's voice in the room, instead of the phone, tablet or computer screen they're trying to show me. They don't do manual mode well.

Could Portal recognize a screen being shown to the camera as an "important" thing, more important than a face or voice and focus on it as long as it's being shown? I'm up for any other offshoots of this idea to make providing tech support to my parents easier. It feels like we're walking on ice, per se, when trying to keep Portal zoomed in on the screen of what they're showing me for help.
