Two experiments were made to determine the effect of ADP card size, thickness, ratio of height to width, and text position on handling ability. Performance times and errors for two groups of subjects were analyzed as were subjects preferences. Results of analyses of variance showed that performance improved with small, thin cards of distinct rectangular shape. Text position had no effect on performance. Subjects generally preferred the card configurations which were most efficient. Author
