Real-time Spatialized Sound Generator on Embedded Wearable Platform

In this paper a novel 3D real-time sound generation and spatialization system, optimized for wearable computers, and enhancements specific for transferring spatialized information to the blind is presented. For visually impaired people, non-visual information sources are paramount to attain accessibility and inclusion. Blind people use their hearing as the main source of information. This research presents a sound engine capable of generating binaural sounds in real-time. Besides real-time binaural sounds, the engine can also enhance real-time spatialization, which results in an improved sound cue perception. The engine performance in providing sound cue feedback was tested through different trials, having visually impaired individuals as test subjects.
