It’s hard to maintain eye contact in a web chat. If you look at your correspondent in your screen, then you’re not looking at your web cam. And if you look at your web cam, then you’re only seeing your correspondent in your peripheral vision.
Wouldn’t it be nice if you could buy a web cam on a stalk. Then you could place the web cam within your field of view while looking at your correspondent. Or how about some mirrors to shift the built in web cam focal point from the top to the interior of the screen.
Add in some software to move your correspondent’s picture into alignment with the webcam location and you have a complete solution.
