TL;DR
This paper presents a new training system for human echolocation using eye-tracking and simulated echoes, aiming to enhance spatial perception skills in sighted individuals.
Contribution
It introduces a novel training interface that combines eye-tracking with virtual echoes to facilitate learning echolocation in humans.

Preliminary results suggest potential for training human echolocation skills.
System enables real-time echo presentation based on eye movements.
Abstract
Bats use a sophisticated ultrasonic sensing method called echolocation to recognize the environment. Recently, it has been reported that sighted human participants with no prior experience in echolocation can improve their ability to perceive the spatial layout of various environments through training to listen to echoes (Norman, et al., 2021). In this study, we developed the new training system for human echolocation using the eye-tracker. Binaural echoes of consecutive downward linear FM pulses that were inspired by feeding strategies of echolocating bats were simulated using the wave equation finite difference time domain method. The virtual echoes were presented to the sighted subject in response to his or her eye movements on the monitor. The latency from eye gazing to the echo presentation wasn't audible delay to perceive. In a preliminary experiment in which the participants were…
