"OK folks, read over the information on the screen... then I'll
remove it and we'll have a short quiz."
This screen is simply mounted too low, and other people block your view of the
image.
As long as the major content was a talking head, it didn't matter too much. But now with greater text and graphic
content in video images, you need to be able to see the whole image or you'll crane your neck and still miss something
that is important.
This means that architects and space planners need to keep ceilings at least
11 ft high at the front of the room, with screens as high as possible. A screen
with a 5ft. vertical dimension can then have its bottom edge high enough to give a clear path over heads (6ft above
the floor).
