In applying the Arc-Segmented Attitude Reference (ASAR) symbology in headmounted displays (HMDs), it is uncertain if there is an optimal position for the symbology within the display. Vision science literature regarding visual asymmetries suggests that performance may differ depending upon the combination of the location of this symbology within the visual field and whether the user is interpreting the symbology to make categorical judgments (e.g., is the aircraft rolling left or right?) or coordinate judgments (e.g., what is the aircraft’s roll angle). Participants were asked to report aircraft roll and climb/dive angles of briefly presented ASAR symbology within the peripheral visual field on a monitor. There were no performance differences between the left and right ASAR positions in either the coordinate or categorical tasks. There were however trends consistent with horizontal-vertical anisotropy.
