The purpose of this study was to investigate if there are any differences between judging the direction in a 3D virtual environment between bi- and binocular presentations. A dynamic air scenario was used, own-ship and target symbols were presented in an exocentric inside-out perspective. The scenario was presented in a HMD (Headmounted Display), with different pictures (binocular) or same picture (biocular) to the subjects´ eyes. The subjects judged azimuth and elevation direction between own-ship and one target symbol. The results showed that there was no difference in judgment between bi- and binocular presentations. However, elevation judgments were affected by the camera placement 10 degrees above and behind own-ship, where some elevation angles were more difficult to judge than others. Other studies haven´t answered if, and when, binocular presentation shall be used. This study was the first in a series of experiments that intend to answer the question if, and when, binocular presentation gives perceptual advantages over biocular presentation.
