Teleprompter problems

I know the new coolio teleprompters that are clear and posed on either side of the speaker are all the rage these days, but at IAEE's opening session last night I felt kind of bad for the speakers, most of whom looked like they were trying to keep up with a tennis match, their heads sproinging wildly from side to side. While Bob Eubanks, the emcee of the evening, did a much better job with it, even he looked a little challenged in trying to make it look more natural.

I don't know the answers, but unless your speakers are pros, you might want to rethink using these things. It was really kind of distracting for the audience, and I can only imagine what it must have been like for the various speakers.
