Reynolds, I. ., & Teng, S. . (2024). Design and optimization of assistive ultrasonic echolocation. The Journal on Technology & Persons With Disabilities, 12. 20.500.12680/vq27zw052 (Original work published 2024)

Overview of Robin, a wearable echolocation device designed to aid navigation and perception for people who are blind or have low vision. A mannequin wears the headset, which emits ultrasound pulses toward a chair, records the reflected echoes, and slows them down for playback in audible frequencies. A web app lets users customize the signal parameters.
