The presented paper discusses the development of an electronic travel aid (ETA) for the
blind, focusing on the aspect of three-dimensional (3D) scene sonification, that is, presenting …

The presented research concerns the development of a sonification algorithm for
representation of 3D scenes for use in an electronic travel aid (ETA) for visually impaired …

Sonification is defined as presentation of information by means of non-speech audio. In
assistive technologies for the blind, sonification is most often used in electronic travel aids …

The paper summarizes a number of audio-related studies conducted by the Sound of Vision
consortium, which focuses on the construction of a new prototype electronic travel aid for the …

This paper describes the development of a system that uses a portable Pocket PC to
generate 3D spatialized sounds, based on the readings from a multidirectional sonar system …

Remotely accessible audio-based virtual tours can offer great utility for blind or vision
impaired persons, eliminating the difficulties posed by travel to unfamiliar locations, and …

Most auditory assistive devices for the Blind employ synthetic speech. These include talking
computer interfaces, reading machines, talking signs, and a plethora of talking appliances …

This paper presents a study on a global evaluation of spatial auditory displays in a
constrained virtual environment. Forty subjects had to find nine sound sources in a virtual …

In this paper we propose an electronic travel aid system for the visually impaired that utilizes
interactive sonification of U-depth maps of the environment. The system is comprised of a …

This paper describes a new assistive technology for sightless persons based on a virtual
auditory display (VAD). This system is intended to encourage its users to improve their map …
