The Sound of Vision Project: On the Feasibility of an Audio-Haptic Representation of the Environment, for the Visually Impaired

Authors: Ómar I. Jóhannesson, Oana Balan, Runar Unnthorsson, Alin Moldoveanu and Árni Kristjánsson in: Brain Sci. 2016, 6, 20 Abstract: The Sound of Vision project involves developing a sensory substitution device that is aimed at creating and conveying a rich auditory representation of the surrounding environment to the visually impaired. However, the feasibility of such an approach is… Continue Reading The Sound of Vision Project: On the Feasibility of an Audio-Haptic Representation of the Environment, for the Visually Impaired

Ground plane detection in 3D scenes for an arbitrary camera roll rotation through “V-disparity” representation

Authors: Piotr Skulimowski, Mateusz Owczarek, Paweł Strumiłło in: 2017 Federated Conference on Computer Science and Information Systems Abstract: In this paper we proposed a fast method for detecting the ground plane in 3D scenes for an arbitrary roll angle rotation of a stereo vision camera. The method is based on the analysis of the disparity map and its… Continue Reading Ground plane detection in 3D scenes for an arbitrary camera roll rotation through “V-disparity” representation

Door detection in images of 3D scenes in an electronic travel aid for the blind

Authors: P. Skulimowski, M. Owczarek and P. Strumillo in: 10th International Symposium on Image and Signal Processing and Analysis, Ljubljana, Slovenia, 2017. Abstract: In this paper we propose a fast method for detecting doors in images of 3D scenes. The proposed method was successfully verified on the recorded indoor RGB-D video sequences acquired by a vision based Electronic… Continue Reading Door detection in images of 3D scenes in an electronic travel aid for the blind

Comparison of HRTFs from a Dummy-Head Equipped with Hair, Cap, and Glasses in a Virtual Audio Listening Task over Equalized Headphones

Authors: Wersényi, György; Répás, József in: Proceedings of the 142nd Convention of the Audio Engineering Society Abstract: Head-Related Transfer Functions (HRTFs) are frequently used in virtual audio scene rendering in order to simulate sound sources at different spatial locations. The use of dummy-head HRTFs (also referred as generic sets) is often criticized because of poor localization performance, leading… Continue Reading Comparison of HRTFs from a Dummy-Head Equipped with Hair, Cap, and Glasses in a Virtual Audio Listening Task over Equalized Headphones

Evaluation of Training to Improve Auditory Memory Capabilities on a Mobile Device Based on a Serious Game Application

Authors: Nagy, Hunor; Wersényi, György in: Proceedings of the 142nd Convention of the Audio Engineering Society Abstract: Capabilities of the auditory memory system were tested in a serious game application developed for the Android mobile platform. Participants played the well-known game of finding pairs by flipping and remembering objects on cards arranged in a matrix structure. Visual objects… Continue Reading Evaluation of Training to Improve Auditory Memory Capabilities on a Mobile Device Based on a Serious Game Application
