Variability of stroke within digits

Abstract

As the demands of the machine on the man increase, how can the man be helped to identify quickly, on sight, numbers from 1 to 10? College students tried to identify 8 variations on each of the 10. "… each digit must be designed on an individual configuration basis taking form, stroke widths, and their combinations into account. Two factors must be considered: a. absolute recognition of the digit as such, b. differentiation (by relative emphasis) of features that suggest similarity (hence ambiguity)." (20 ref.)
