The purpose of the study is to answer three basic questions with respect to segmented numerics are segmented numerics more difficult to read than conventional numerics if so, can subjects be trained to read segmented numerics at a level comparable to conventional numerics given sufficient practice and will subjects reading proficiency of segmented numerics degrade over time without additional practice. The following conclusions are supported by data from the study at short exposure times seven segment numerics are more difficult to read and require significantly more practice to lower error rates to an acceptable level and proficiency in reading seven segment numerics shows a significant loss following moderate time one month without practice, and longer time periods four months without practice produce even greater decrements.
