Abstract
An experiment was conducted to study user behavior while entering data in two different locations on a visual display (VDT) screen. Sixteen subjects (eight experienced and eight novice VDT users) performed a data entry task which emphasized screen-keyboard interaction. The entry area was placed either at the top (line 2) or bottom (line 23) of the display, with trials blocked for a given condition. Statistically significant differences were obtained for three anthropometric measures and one time measure on main effects of line location and user experience level. Although significant differences in absolute measures were found, both user groups show the same proportionate improvement when the command line is presented at the bottom, compared with when it is at the top.
