An overwhelming quantity of data must be assimilated by personnel monitoring a typical mission. Data from these missions must be monitored and crucial life and death decisions made by personnel within a short period of time. The need for a precise human engineered computer interface resulted in the development and laboratory testing of a 3-D display concept for monitoring a typical DoD air surveillance display.
Additional testing is needed to determine the benefit of the vertical bar graph.
This experiment examines the possibility of enhancing user performance using a 3-D environment. The standard 3-D environment was also augmented using a vertical bar graph display concept. The results of this study are significant since user performance for a DoD or DoT display can impact a number of lives. The experiment was designed to measure user performance with regards to time response and accuracy of actions. If the user accidentally selects objects other than enemy targets, he or she could deselect the objects by clicking the mouse on them a second time.
