Free Idea # 243 - Auto focusing webcam

Develop a pendant, webcam, and accompanying software such
that, when the pendant is worn, the webcam would automatically
follow and focus on the wearer. This might be especially helpful
for people with a visual impairment who want to video conference
but cannot tell whether they are in shot or in focus, and for anyone
else who teaches or entertains via a webcam but likes to move
around as they work.
