Effect of Non-Visual Cues on Spatial Navigation Abilities

While vision plays a vital role in spatial navigation, the contribution of non-visual sensory cues remains an active area of research. This study investigates the integration of proprioceptive and audio-proprioceptive cues in learning and recalling spatial trajectories using the SensFloor® system. Blindfolded sighted participants were tasked with navigating simple and complex trajectories, relying either solely on proprioceptive input or on a combination of proprioceptive input and an acoustic stimulus, specifically white noise. The findings demonstrate a significant improvement in spatial recall when white noise is introduced during the learning phase, highlighting the role of auditory cue in enhancing spatial navigation. Additionally, the study emphasizes the technical accuracy of the SensFloor® technology in capturing detailed walking parameters such as trajectory, and movement patterns. This real-time monitoring capability underscores the system's potential for research applications, as well as for clinical use in mobility training programs. By providing a practical framework for assessing and improving navigation skills, this research has direct implications for the development of assistive technologies. It also offers a robust foundation for designing targeted training programs that can enhance the mobility and self-sufficiency of individuals with vision impairments, further leveraging SensFloor® as a tool for improving accessibility and independence.
