cool trick but we all know who will end up using this the most:

advertisers. another way for them to "gauge" their reach and brand appeal. or something.

literally i feel like every new thing that comes to the browser, a marketer at a company thinks, 'how can we exploit this to put more junk into the face of other people?'

i am not against advertising, i just think most of them have no limits in terms of what they'll exploit at the expense of their own users.




Well, advertisers couldn't use this without asking permission for a user's webcam, which would be a non-starter. I choose the less cynical path and say this could be tremendously useful for remote user testing.


Remote usability testing would be fantastic. This could be useful for local testing as well. Having a library or tool that could generically sit in front of a site to show where users look when taking action X sounds beneficial to me.

I can also imagine on a lighter note this being used for games where you look to where you want to move a character (maybe blink twice for confirmation).
