Our work is dealing with alternative interaction modes for visually impaired and blind people to use computers. The aim of the proposed approach is to exploit the human hearing capabilities to a better degree than this is ...

This paper presents a system developed at NASA Langley Research Center to render aircraft flyovers in a virtual reality environment. The present system uses monaural recordings of actual aircraft flyover noise and presents ...

Sound Traffic Control (STC) is a system for interactively controlled 3-D audio, displayed using a loudspeaker array. The intended application is live musical performance. Goals of the system include flexibility, ease of ...

As 3D audio becomes more commonplace to enhance auditory environments, designers are faced with the challenge of choosing HRTFs for listeners that provide proper audio cues. Subjective selection is a low-cost alternative ...

This research presents a novel 3D audio playback method in which real-time head-tracking is maintained with an unlimited number of simultaneous sound sources. The method presented relies on using a 500-900MByte sound buffer ...

Contemporary use of sound as artificial information display is rudimentary, with little 'depth of significance' to facilitate users' selective attention. We believe that this is due to conceptual neglect of 'context' or ...

A method of computationally efficient 3D sound reproduction via headphones is presented using a virtual Ambisonic approach. Previous studies have shown that incorporating head tracking as well as room simulation is important ...

This paper describes the development of an XML-based format called Audio3D for the declarative description of acoustic environments and sound sources for 3D auditory displays by an audio designer without the need of ...

This paper describes a computer program designed to teach orientation and mobility skills to visually impaired persons. The system utilizes off-the-shelf computer hardware and a proprietary virtual reality authoring library ...

Spatial auditory displays were designed, flown, and evaluated using the Simulation Training Research Advanced Testbed for Aviation (STRATA), a AH-64a Apache simulator, located at the Army Research Institute (ARI) at Fort ...
