Polycom's invisible camera
Go to Google and do an image search for "video conference". What you'll find are hundreds of examples of false advertising. Big participants with perfect eye contact. It simply doesn't happen and it's poor form that marketing folk feel the need to falsely promote what doesn't exist except under the most (im)perfect of circumstances. Imperfect because if the remote participants appear to have perfect eye contact, they are actually looking at a camera, not at you, rendering video conferencing absolutely pointless.
How about this one? Cables aren't even necessary for this one. Plus the camera is in the most ludicrous location possible. Unless that thing has a great vertical field of view, it's going to capture that woman's neck and shirt. Even if the FOV reached her face, the camera is pointing directly up her nose. Maybe looking at your camera and not the person is a good idea after all...
Video conferencing will never look like the marketing pictures. If a customer buys off on the technology, they will absolutely be disappointed with the result if the pictures are their expectation.
