Exploring direct downconversion of ultrasound for human echolocation

ABSTRACT

Human-computer interfaces for mobility devices to aid visually impaired individuals are deficient in the ease of use of systems. This paper examines the techniques used by blind individuals to spatialize naturally in their environments and seeks to explore the possibility of providing the same information in a manner that may be otherwise more socially acceptable.
