Experimental studies of reliability of symbolic information perception from the aviation LCD panel

Results of tachistiscopic experiments on reliability of symbol recognition on LCD panel as a function of screen definition (640 x 480, 800 x 600 and 1024 x 768 pixels), angular size of a picture element (10, 15, 20 and 30 angular min) and luminance contrast (LC) with the background (0.2 to 1.4 stand...

Summary:Results of tachistiscopic experiments on reliability of symbol recognition on LCD panel as a function of screen definition (640 x 480, 800 x 600 and 1024 x 768 pixels), angular size of a picture element (10, 15, 20 and 30 angular min) and luminance contrast (LC) with the background (0.2 to 1.4 standard units) are presented. The obtained quantitative relations indicate significance of the above parameters for recognition reliability. Symbols with the size of 30 angular min and LC of 0.5 were recognizable irrespective of screen definition in the study. Recognition of symbols 20 and 15 angular min of size was much dependent on screen definition and LC of symbols. For symbols of size 10 angular min and LC ≥ 1.0 the recognition probability did not exceed 0.59-0.7.
