Abstract
Educational Testing Service's Advanced Technology Systems (ATS) Division has been developing numeric handprint recognition capability since 1989. Experiments have verified that machine recognition is less accurate than human recognition, so key-entered data are usually preferred. However, the cost of keying is now higher than the cost of machine recognition. Until machine accuracy surpasses key entry accuracy, strategies like redundant forms design can be used to close the accuracy gap.
