Comparison of Two Data Entry Methods
The purpose of this experiment was to measure the effects of a number of display and input variables on the relative speed and accuracy of input performance when using point-in and type-in data entry methods for entering alphabetical material into automatic data processing machines. The factors tested in the experimental design were: types of arrangement of display material, density of material, different types of input tasks, typing ability, sex, and relative location of the keypunch device to the operator. The major finding of this study was that the point-in data entry method was a more accurate input technique than either the type-in or mixed point-in type-in data entry methods when measured under the effects of the independent variables.
