STANDARDIZATION OF TYPEWRITER FONTS FOR AUTOMATIC READING.

Abstract

The object was to provide engineering data in support of standardization of typewriter fonts and related features for optical scanning application. Primary emphasis was placed on investigation and evaluation of existing typewriter fonts and includes an evaluation of a type font developed by Subcommittee X3.1 on Character Recognition under American Standards Association Sectional Committee X3. Investigations were by computer programmed assessment of each font using a technique developed partly under Contract AF30(602)-2642 (AD-404 846) sponsored by Rome Air Development Center and partly under continuing Link sponsored character recognition efforts (AD-623 613, -623 614, -623 621). Evaluations were accomplished by extending the vocabulary capacity of a Link Multifont Page Reader to permit machine reading of a significant volume of typewriter-prepared documents. Reject and error rates were determined in this manner for each of several type styles considered. (Author)
