Further Research on the Effect of Viewing Angle and Symbol Size on Reading Ease

摘要

The effects of viewing angle and visual symbol size upon the time required to read familiar words were studied for angles of 90, 60, 45 and 30 degrees and for symbols whose height subtended 16 and 10 minutes of arc at the viewer's eyes. Recommendations for largeboard, wall-display layout and viewer-seating arrangements are offered. (Author)
