Numerical display problems.
After reviewing current knowledge about the presentation of dynamic information using numerical displays, this paper describes a series of experiments to assess their effectiveness in a tracking task. It is concluded that a numerical display can provide sufficient dynamic information to allow the performance of a variety of tasks, but appears to demand more of the operator's attention than other types. A number of other problems about numerical displays are noted to need investigation.
