Abstract : Many automated data-handling systems require handprinting of entries on special forms. This investigation sought and evaluated methods for bypassing handprinting in the manual entry of data into computers. The state-of-the-art in manual input devices was surveyed and summarized; the requirements of users in the intelligence community were studied, and several tentative input methods were proposed and compared. Three laboratory experiments were performed to obtain data on human performance rates in various input modes, including writing, printing, marking, and keying with both print and scope feedback. It is concluded that devices applicable to the problem are available today; their use would be more expensive but also faster, more accurate, and more versatile than current methods. Conversion to new input methods might initially slow down the input rate, but practice would be likely to restore former speeds. It is recommended that any further study of conversion of input method be preceded by an operations analysis of the entire function involved, stressing realism rather than simulation. (Author)
