The next Sound of Vision project meeting is set to take place at the Buda Mercure hotel in Budapest, between February 16-19, 2016. The project team will assess current achievements and will weigh the advantages and drawbacks of each technology proposed for use within the project’s deliverable, in order to ensure that it remains safe,… Continue Reading Upcoming Sound of Vision meeting scheduled!
DetailsOn the international “White Cane Safety Day” which is held on October 15 every year, the first Charity Relay Run was organized in Győr, Hungary. Together with our local partners at the blind community, Lions Club and University, the Sound of Vision team used the occasion for distributing our mission, sharing information and establishing new contacts. Registration fees were donated for charity to the blind community. Continue Reading White Cane Safety Day Event
DetailsAuthors: Mateusz Owczarek, Przemysław Barański and Paweł Strumiłło in: Proceedings of the 2015 Federated Conference on Computer Science and Information Systems. ACSIS, Vol. 5, pages 875–881 (2015) Abstract: In this work we study the methods for pedestrian tracking in video sequences and indicate various applications of these methods ranging from surveillance systems to aiding the visually impaired… Continue Reading Pedestrian Tracking in Video Sequences: a Particle Filtering Approach
DetailsAuthors: Piotr Skulimowski and Pawel Strumillo Abstract: We present a software tool called a stereovision egomotion sequence generator that was developed for testing visual odometry (VO) algorithms. Various approaches to single and multicamera VO algorithms are reviewed first, and then a reference VO algorithm that has served to demonstrate the program’s features is described. The program offers… Continue Reading Verification of visual odometry algorithms with an OpenGL-based software tool
DetailsThe second consortium meeting was held at the Institute of Electronics at the Lodz University of Technology and was organized by the Polish consortium partner. The meeting was attended by 32 participants from Iceland, Romania, Italy, Hungary and Poland. The agenda of the meeting was focused on the status reports and action plans for the second work… Continue Reading Consortium meeting at the Lodz University of Technology, Lodz, Poland, September 22-25, 2015
DetailsAuthors: György Wersényi, Hunor Nagy and Ádám Csapó 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 important being the stimuli themselves and the method used… Continue Reading Evaluation of Reaction Times to Sound Stimuli on Mobile Devices
DetailsAuthors: Oana Bălan, Alin Moldoveanu Hunor Nagy, György Wersényi Nicolae Botezatu, Andrei Stan and Robert-Gabriel Lupu Abstract: 3D binaural sounds play an important role in the development of navigational systems for the blind people. The use of generic HRTFs in virtual auditory displays significantly affects the acoustic spatial resolution and the listener’s ability to make localization judgments… Continue Reading Haptic-Auditory Perceptual Feedback Based Training for Improving the Spatial Acoustic Resolution of the Visually Impaired People
DetailsAuthors: G. Wersényi and J. Wilson Abstract: Measurements for spatial hearing research, binaural recordings, virtual reality techniques etc. often rely on Head-Related Transfer Functions of human subjects, head-tracking techniques etc. Individually measured HRTFs and recordings on human heads may result in more accurate localization and sound field rendering. On the other hand, the measurement and recording procedure… Continue Reading Evaluation of the Range of Head Movements in Measurements and Recordings with Human Subjects using Head-Tracking Sensors
DetailsThe National Institute for the Blind, Visually Impaired, and Deaf-blind in Iceland is a national institute governed by the Ministry of Welfare and was established in 2009. The main goals of the institute are rehabilitation, education, and counseling. The primary purpose of the institute is to service clients, their families, teachers, and other professionals in… Continue Reading First lessons in Orientation and Mobility
DetailsAuthors: Ádám Csapó, György Wersényi, Hunor Nagy and Tony Stockman Abstract: This paper summarizes recent developments in audio and tactile feedback based assistive technologies targeting the blind community. Current technology allows applications to be efficiently distributed and run on mobile and handheld devices, even in cases where computational requirements are significant. As a result, electronic travel aids, navigational assistance modules, text-to-speech applications, as well… Continue Reading A survey of assistive technologies and applications for blind users on mobile platforms: a review and foundation for research
