Nope. It was located directly outside the instructors office door, on
a wall that was adjacent to one of the larger lab rooms. There was no
way to mistake it for a doorbell to either the office or the lab as it
was roughly half way in between the two doors. It was also at eye
level, which is rather an unusual elevation for a doorbell button. The
idea was to position it in a manner offering no clue as to its purpose
or function.
I suspect I would have obtained similar results if I had placed the
doorbell button on the ceiling, with a broom and chair located nearby
to make it easy to poke.
Incidentally, somewhat later, I found myself engaged in the design of
one of the first microprocessor based marine radios. We were limited
to 16 buttons on the front panel. The mechanical designer came from
telecom, where all the label are traditionally tiny, abbreviated,
incomprehensible, and/or absent. The front panel was all of those.
While doing booth duty at the annual Cow Palace boat show, I noticed
that a substantial number of visitors were having a difficult time
operating the radio, and were poking at buttons almost randomly to see
what the display would do. The front panel labels were subsequently
enlarge, de-obfuscated, and generally made readable. The next year,
the amount of random button pushing was dramatically decreased.
