Auditory and tactile frequency mapping for visual distance perception: A step forward in sensory substitution and augmentation.

ABSTRACT: Vision is crucial for daily tasks and interacting with the environment, but visual impairment can hinder these activities. Many sensory substitution products and studies prioritize providing abundant and accurate information, yet often overlook the inherent relationship between different modalities, potentially preventing users from receiving information intuitively. This study investigated the representation of visual distance using auditory and vibrotactile frequency through a series of psychological cross-modal matching experiments. By establishing mapping functions between auditory/vibrotactile frequency and visual distance, we aim to facilitate the design of sensory substitution devices that take visual distance information (ranging from 1 m to 12 m) and convert it into non-visual inf
