An Evaluation of Data Entry Devices

Abstract

Guidelines for the USAF Global Positioning System (GPS) Integration (GIG) called for the use of alphanumeric identifiers to define waypoints. Based on this requirement, the question arose whether or not a full alphabetic keypad for data entry was required for integrating GPS into aircraft. The study objective was to assess subject performance using 6 data entry devices and 6 data types. The data entry devices were: (1) Full alphanumeric keypad, (2) Telephone type, (3) Dual knob, (4) Single knob, (5) Rocker switch, and (6) International Civil Aviation Organization database table. Subjects performed a simple tracking task while simultaneously entering alphanumeric data. Performance data was collected for the tracking and data entry tasks, and subjective data was collected from questionnaires. Overall, the objective and subjective data indicated the most preferred device and best performance was obtained with the alphanumeric keypad. If space is a consideration, the ICAO table was second place in performance and preference.
