Auditory and Haptic Spatial Cognitive Representation in the Case of the Visually Impaired People

Authors: Oana Bălan, Alexandru Butean, Alin Moldoveanu, Florica Moldoveanu in: 22nd International Congress on Sound and Vibration, Florence, 2015 Abstract: Navigating in an unknown environment is a difficult task for the visually impaired people, as they are required to rely primarily on the haptic or auditory cues, in compensation for the lack of sight. However, their orientation and… Continue Reading Auditory and Haptic Spatial Cognitive Representation in the Case of the Visually Impaired People

3D Audio and Haptic Interfaces for Training the Spatial Acoustic Resolution in Virtual Auditory Environments

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: 21st International Conference on Auditory Display (ICAD-2015), Graz, 2015 Abstract: In order to design an effective audio-based assistive device, we have to consider the users’ sound localization performance and spatial auditory resolution. As most of the virtual auditory displays employ 3D binaural sounds synthesized from non-individualized Head Related Transfer Functions… Continue Reading 3D Audio and Haptic Interfaces for Training the Spatial Acoustic Resolution in Virtual Auditory Environments

Multimodal Perceptual Training Improves Spatial Auditory Performance in Blind and Sighted Listeners

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: Archives of Acoustics (Accepted for publication) Abstract: The use of individualized Head Related Transfer Functions (HRTF) is a fundamental prerequisite for obtaining an accurate rendering of 3D spatialized sounds in virtual auditory environments. The HRTFs are transfer functions that define the acoustical basis of auditory perception of a sound source… Continue Reading Multimodal Perceptual Training Improves Spatial Auditory Performance in Blind and Sighted Listeners
