Abstract

When seated users of multimodal augmented reality (AR) systems attempt to navigate unfamiliar environments, they can become disoriented during their initial travel through a remote environment that is displayed for them via that AR display technology. Even when the multimodal displays provide mutually coherent visual, auditory, and vestibular cues to the movement of seated users through a remote environment (such as a maze), those users may make errors in judging their own orientation and position relative to their starting point, and also may have difficulty determining what moves to make in order to return themselves to their starting point. In a number of investigations using multimodal AR systems featuring realtime servocontrolled movement of seated users, the relative contribution of spatial auditory display technology was examined across a variety of spatial navigation scenarios. The results of those investigations have implications for the effective use of the auditory component of a multimodal AR system in applications supporting spatial navigation through a physical environment.
