Título Factors affecting the speed of acquisition of tabulated information from visual displays
Información bibliográfica Mar. 1984, Vol.27, No.3, p.321-330. 18 ref.
Resumen The task studied was that of reading tabulated information following a change in the focus of fixation. Subjects fixed a marked point on a VDU and then looked across to an entry in a table of three-digit numbers. This was read out, and the overall reaction time recorded. This time was found not to vary with the vertical position of the entry in the table, for viewing distances of 570, 885 and 1140mm. The horizontal angular separation was varied both within the display and by means of viewing distance. Reaction times increased with separation of the initial fixation point and the target for a fixed viewing distance. Changes in angular separation due to viewing distance had little effect. Eye movement recordings showed that the latency of eye movements was constant, but that the latency of response following a displacement of fixation varied in the same way as the overall reaction time.
