Emphatic Trials of a Teleassistance System for the Visually Impaired

Authors: Przemyslaw Baranski, Pawel Strumillo in: Journal of Medical Imaging and Health Informatics, December 2015 Abstract: In this paper we focus on a special type of electronic travel aids for the visually impaired termed teleassistance systems. The operation principle of such systems is to transmit a video stream from a camera carried by a navigated… Continue Reading Emphatic Trials of a Teleassistance System for the Visually Impaired

Evaluation of Reaction Times to Sound Stimuli on Mobile Devices

Authors: György Wersényi, Hunor Nagy, Ádám Csapó in: 21st International Conference on Auditory Display (ICAD-2015) Abstract: When developing new devices for assistive technology, it is important to consider auditory response times to different kinds of warning and navigational sounds. Perception, processing and action following the presentation of auditory stimuli depends on several parameters, the most… Continue Reading Evaluation of Reaction Times to Sound Stimuli on Mobile Devices

Evaluation of Head Movements in Short-term Measurements and Recordings with Human Subjects using Head-Tracking Sensors

Authors: György Wersényi, J. Wilson in: Acta Technica Jaurinensis, Vol. 8, No.3, pp. 218-229, 2015 Abstract: Measurements for spatial hearing research, binaural recordings, virtual reality techniques etc. often rely on Head-Related Transfer Functions of human subjects and head-tracking techniques. Individually measured HRTFs and recordings on human heads may result in more accurate localization and sound… Continue Reading Evaluation of Head Movements in Short-term Measurements and Recordings with Human Subjects using Head-Tracking Sensors

Frequency Estimation of the First Pinna Notch in Head-Related Transfer Functions with a Linear Anthropometric Model

Authors: Simone Spagnol, Federico Avanzini in: 18th International Conference on Digital Audio Effects (DAFx-15), Trondheim, 2015 Abstract: The relation between anthropometric parameters and Head-Related Transfer Function (HRTF) features, especially those due to the pinna, are not fully understood yet. In this paper we apply signal processing techniques to extract the frequencies of the main pinna notches (known as N1,… Continue Reading Frequency Estimation of the First Pinna Notch in Head-Related Transfer Functions with a Linear Anthropometric Model

Relative Auditory Distance Discrimination with Virtual Nearby Sound Sources

Authors: Simone Spagnol, Erica Tavazzi in: 18th International Conference on Digital Audio Effects (DAFx-15), Trondheim, 2015 Abstract: In this paper a psychophysical experiment targeted at exploring relative distance discrimination thresholds with binaurally rendered virtual sound sources in the near field is described. Pairs of virtual sources are spatialized around 6 different spatial locations (2 directions × 3 reference distances)… Continue Reading Relative Auditory Distance Discrimination with Virtual Nearby Sound Sources

Spatial Auditory Representation in the Case of the Visually Impaired People

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: Journal of Information Systems & OperationsManagement, vol. 9, no. 1, May 2015,pp. 1-11 Abstract: Over the years, it has been widely believed that the blind individuals possess enhanced sound localization abilities that help them to navigate and orient in space in the lack of visual stimuli. In addition to this,… Continue Reading Spatial Auditory Representation in the Case of the Visually Impaired People

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
