Computer-generated, three-dimensional pictures provide a highly natural means of presenting map information. A sequence of computer views can be linked to provide a realistic tour, or computer movie map, of a specific locale. A prototype computer movie map was produced for the fictitious desert town of Dar-El-Mara. An experimental study, involving 45 participants, was conducted to examine the comparative effectiveness of the computer movie map versus a conventional map in teaching the map user about Dar-El-Mara and the effect of movie map display size on performance effectiveness. Results of the study clearly showed a substantial advantage in favor of the movie map medium. Major map performance skills were significantly enhanced compared to a baseline of conventional map performance. For example, with the movie map, errors in self- localization were reduced by factors of 6 to 30, error in spatial relations was reduced by more than half, and topographical knowledge was improved by 30. It appeared that a large-screen projected TV display was marginally better than a small-screen TV monitor display, particularly for self-localization and topographical knowledge, but the effect was not great. The results suggest several immediate C3 applications of the computer map technology these include local familiarization, maneuver aiding, and command coordination.
