“…Binaural audio is excellent for this application because it can accurately relay spatial sources using naturally-occurring, subtle timing and amplitude differences between ears. Several studies have demonstrated the utility of localized audio for navigational aids (Cohen, Fernando, Nagai, & Shimizu, 2006;Gunther, Kazman, & MacGregor, 2004;Holland, Morse, & Gedenryd, 2002;Klatzky, Marston, Giudice, Golledge, & Loomis, 2006;Lokki & Grohn, 2005;Loomis, Golledge, & Klatzky, 1998;Simpson et al, 2005). Further, given its nonverbal presentation of spatial information, it is assumed that the tonal aid recruits the visuospatial sketchpad rather than the phonological loop.…”

Research has demonstrated navigational aids impair spatial memory, but has not considered important spatial cognitive concepts. For example, impairment may stem from spatial perspective switches between route-based aids and survey-based memory assessments. Further, the verbal format of aid instructions may selectively interfere with verbal working memory (VWM). To address these potential explanations, participants navigated desktop virtual environments in a goal-directed manner. In each within-participants condition, participants either navigated with a verbal or tonal aid that presented mixed spatial perspective instructions or without aid. Both aids yielded slight navigational advantages and steep spatial memory costs despite their mixed perspective instructions. The equivalent impairment between information formats suggests navigational aids impair spatial memory by dividing attention rather than selective interference of VWM.

“…Visual spatial knowledge acquisition and navigation has been studied extensively in natural and virtual environments [46,47,48,49]. Furthermore, case studies show that humans are also able to navigate in virtual acoustic environments based on (3D) auditory cues and beacon sounds [50,51,52,53]. However, fewer studies have investigated the effect of audiovisual presentation on navigation performance [54,55].…”

It has been shown that multisensory presentation can improve perception, attention, and object memory compared with unisensory presentation. Consequently, we expect that multisensory presentation of landmarks can improve spatial memory and navigation. In this study we tested the effect of visual, auditory and combined landmark presentations in virtual mazes on spatial memory and spatial navigation. Nineteen participants explored four different virtual mazes consisting of nodes with landmarks and corridors connecting them. Each maze was explored for 90 seconds. After each exploration, participants performed the following tasks in fixed order: 1) draw a map of the maze, 2) recall adjacent landmarks for three given landmarks, 3) place all landmarks on the map of the maze, and 4) find their way through the maze to locate five given landmarks in fixed order. Our study shows significant effects of multisensory versus unisensory landmarks for the maze drawing task, the adjacency task, and the wayfinding task. Our results suggest that audiovisual landmark presentations improve spatial memory and spatial navigation performance in virtual environments.

This paper presents a study about the effect of using additional audio cueing and Head-Related Transfer Function (HRTF) on human performance in sound source localization task without using head movement. The existing techniques of sound spatialization generate reversal errors. We intend to reduce these errors by introducing sensory cues based on sound effects. We conducted and experimental study to evaluate the impact of additional cues in sound source localization task.The results showed the benefit of combining the additional cues and HRTF in terms of the localization accuracy and the reduction of reversal errors. This technique allows significant reduction of reversal errors compared to the use of the HRTF separately. For instance, this technique could be used to improve audio spatial alerting, spatial tracking and target detection in simulation applications when head movement is not included.
