Transparent Screens on the Horizon?
mhesseltine writes "According to United Press, researchers in Japan are developing transparent transistors. This could bring about see-through screens like those in Minority Report. Also, I imagine would be better heads-up displays (HUDs) for vehicles, layered flat panel displays, and new methods of interfacing with information screens."
This is already possible with one-way mirrors reflecting the screen, but one-way transparent screens would make it easier.
Instead of having the camera at the top of the screen and looking back and forth, put it directly behind the middle of the screen, about 2/3 of the way up. Or have smart software that would track where the other person's eyes are and put the camera between their eyes so you could look directly at them.
I believe that this is a big factor in why videoconferencing always "feels strange" and perhaps part of why it hasn't caught on.
