Des chercheurs de l’université de Grenade travaillent actuellement sur des optimisations visant à améliorer l’accessibilité de Facebook pour les personnes malvoyantes ou non-voyantes. Une démarche visant à combler un manque sur la Toile, où les réseaux sociaux à destination des déficients visuels existent, mais sont limités.

« Jusqu’à présent, il n’y avait que des réseaux sociaux spécialement développés pour les personnes ayant une déficience visuelle, Blindworlds » explique Josefa Molina López, la chercheuse à l’origine de l’étude. « Mais les réseaux sociaux standards ne sont pas adaptés aux lecteurs d’écran qui permettent de les rendre accessibles aux personnes aveugles » déplore-t-elle.

Car les internautes ayant une déficience visuelle ont à leur disposition des logiciels, qualifiés de « lecteurs d’écran », qui permettent d’optimiser la lecture de sites et programmes via un système de synthèse vocale ou un afficheur en braille. Mais pour que ces outils fonctionnent correctement, il faut que les sites Internet soient adaptés… ce qui n’est pas le cas de Facebook, pourtant le plus grand réseau social au monde.

Les chercheurs ont donc mené une étude avec trois groupes d’utilisateurs : un premier constitué d’internautes sans problème de vue, un second avec des personnes ayant une déficience visuelle sévère et une connaissance approfondie des lecteurs d’écran, et enfin, un troisième également constitué de malvoyants, mais avec peu d’expérience des lecteurs d’écran. Les scientifiques ont analysé le temps passé par les différents groupes pour réaliser certaines actions sur Facebook, ainsi que les astuces trouvées pour contourner les difficultés. Dans le cas où les internautes se trouvaient bloqués, les chercheurs ont taché d’en trouver la cause.

Les données récoltées ont permis aux chercheurs espagnols de dresser un état des lieux de l’accessibilité de Facebook aux malvoyants, et se sont lancé dans une démarche de « refactoring atomique » : en d’autres termes, ils ont cherché à améliorer le code source de Facebook s’en en altérer le comportement d’origine, pour l’optimiser.

Les premiers résultats du système, toujours en phase de test, seraient particulièrement concluants selon les chercheurs : les délais de réalisation d’actions seraient largement revus à la baisse, et des actions interdites ou bloquantes seraient désormais réalisables par les utilisateurs. Pour autant, la démarche n’est pas encore au stade du déploiement et les scientifiques ne se sont pas encore avancés quant à sa mise en place.

Researchers design new imaging technique for identifying age, sex of a corpse

Escrito por

Picture on the left: horizontal section across the symphysis of the pubis. Picture on the right: sagittal section across the right symphysis surface. Researchers at the University of Granada, Spain, have designed a new computing system that determines the age and sex of a corpse with a reliability of 95%. This system is based on free software called Image and a free DICOM displayer called K-Pacs. This state-of-the-art system is very different from the traditional macroscopy systems used to evaluate the osteoarticular features of a corpse, and it is much faster and user-friendly. Ads by Google Skeletal System in 3D – Study Bones, Ligaments & Joints Animations, Illustrations & Quizzes – www.visiblebody.com Rabbit Monoclonal Abs – 10000+ Proteins,Antibodies,cDNA, Best Quality Rabbit Mabs,ELISA Kits – www.SinoBiological.com/Antibody The authors of the study examined 169 DICOM files (Digital Imaging and Communication in Medicine, the international standard for distributing medical images) of CT scans of patients between 17 and 90 years of age supplied by the Castile-La Mancha health service (SESCAM). Histogram analysis The researchers examined the sagittal sections of the the articular surface of the pubic symphysis and the pubis itself, thus obtaining four sections: two sections of the right and left symphysis, and two sections of the pubis. Imaging techniques were used to analyze sections, histograms of the structures were obtained and the statistical variables of histograms were entered into the Image program to determine how histograms are related to age and sex. «Age and sex are essential for the identification of corpses, and the pubis is especially relevant for this purpose. In our study, we exploited the great capacity of computer systems to discriminate between the different gray shades in a histogram (the human eye only can discriminate 64) to determine how histograms can provide information about age and sex», Lopez Alcaraz states. The researcher notes that this technique might be useful in virtopsies or virtual autopsies. «At present, the main drawback of virtual autopsy is that it cannot replace the macroscopic analysis of tissues for the identification of potential pathologies, determining whether an injury was inflicted before or after death, assessing the course of an injury…etc. As the new technique is based on image analysis, it can be applied to virtual autopsy to provide many more answers than traditional analysis methods. The researcher affirms that this is a step forward in the field of Forensic Anthropology. «We should replace traditional osteological methods with new technologies and exploit the advantages of the visual communications and image era», the researcher states. In addition, this study contradicts the traditional assumption in Forensic Anthropology that the pubis is only useful for the identification of corpses in the age range of 20 to 40 years. «We obtained excellent results in the identification of corpses of people older than 50 years, especially in men», the author notes.
