ODA Pilot Study II:Selection of an Interactive Graphics Control Device for Continuous Subjective Functions Applications.

摘要

This report presents the results of a pilot study undertaken to evaluate the performance of three interactive graphics control devices--light pen, track ball, and joy stick--for the types of 'drawing' tasks required to determine continuous subjective functions (CSF's). This report includes (1) a brief review of CSF'S in the context of computer-aided decision making; (2) a description of the types of drawing tasks used in generating CSF's; and (3) The experimental design, procedures, performance measures, and interpretation of results. The results of this study conclude that the track ball is the best overall control device for use in subsequent CSF studies. (Author)
