3.2.4. Selection of monitor
The decision to use a backpack eliminated the requirement that
computational abilities be included within the camera head and allowed
the use of a simple touch screen monitor; alternatively, if a
backpack was not used, a tablet PC could be used as the monitor.
The criteria used to select the monitor were that it could be physically
attached to the camera head, that it incorporated a touch
screen, and that it was inexpensive. Thus, the camera head could
be held in one hand and operation parameters set using the other
hand and the monitor.
