Double-sided or front-and-back monitors
Produce monitors with the same, interactive screen on both the front and back. This would prevent having to turn ones monitor so that a person sitting opposite can view what is being discussed. This would be useful in financial markets, doctor offices, insurance companies, businesses, schools, and anywhere that an individual wants to show another what is on their screen, but had to constantly turn the screen for the other person to view it. One side (front) monitor allows the presenter to continue without turning it for the viewer to see, while the viewer can see what is being presented, no screen turning, no craning necks. Both presenter and viewer could have access, by mouse, of pointing items of concern.
