(see Why not use this idea to generate revenue?)
Here I am standing in front of a class that I’ve scheduled. Training Centres of Canada are my hosts. Eight invited attendees are keying away, I am gazing out at the backs of 24 flat-screen LCD monitors atop the desks, and occasionally walking around, between the aisles, to see what problems face the students when it hits me:
Whoever first makes a flat-screen monitor with two screens – one at the “front” and one at the “back” will corner the market in classroom sales.
(Yes, class-room training is alive and well!)
What a time-saver it would be, and less embarrassing to the student, if the facilitator could glance at the “back” of the monitor and see in a flash that Esmerelda is still in the Visual Basic Editor, and just needs to Alt-Tab …
Seems to me there is no extra circuitry.
It ought to be a matter of an extra layer of glass, plasma, liquid crystal or what-have-you.
Plus a few extra soldered connections; a slightly stronger power unit.
Could be quite a drawing-card for the schools, too.
