A METHOD FOR INCREASING EFFICIENCY OF DIAL CHECK READING

The conventional check-reading display, using dials in rows and columns with pointers aligned at the 12 o'clock position, was compared to a similar display with pointers connected by straight lines, i.e., with the pointers in normal position they are seen as segments of straight lines. In this...

Description
Summary:The conventional check-reading display, using dials in rows and columns with pointers aligned at the 12 o'clock position, was compared to a similar display with pointers connected by straight lines, i.e., with the pointers in normal position they are seen as segments of straight lines. In this latter display, called the extended-line display, the subjects' task was merely to detect a break in a line, rather than to detect a deviant pointer. Detection of deviant dials was consistently superior with the extended-line dislay; the displays did not differ with respect to the observers' ability to localize deviant dials in the display array.
