Speak with signs: Active learning platform for Greek Sign Language, English Sign Language, and their translation.
arXiv: Human-Computer Interaction, 2020Co-Authors: Maria Papatsimouli, Lazaros Lazaridis, Konstantinos-filippos Kollias, Ioannis A. Skordas, George F. FragulisAbstract:Sign Language is used to facilitate the communication between Deaf and non-Deaf people. It uses signs-words with basic structural elements such as handshape, parts of face, body or space, and the orientation of the fingers-palm. Sign Languages vary from people to people and from country to country and evolve as spoken languages. In the current study, an application which aims at Greek Sign Language and English Sign Language learning by hard of Hearing people and talking people, has been developed. The application includes grouped signs in alphabetical order. The user can find Greek Sign Language signs, English sign language signs and translate from Greek sign language to English sign language. The written word of each sign, and the corresponding meaning are displayed. In addition, the sound is activated in order to enable users with Partial Hearing Loss to hear the pronunciation of each word. The user is also provided with various tasks in order to enable an interaction of the knowledge acquired by the user. This interaction is offered mainly by multiplechoice tasks, incorporating text or video. The current application is not a simple sign language dictionary as it provides the interactive participation of users. It is a platform for Greek and English sign language active learning.

diffusion tensor imaging of the auditory pathway in sensorineural Hearing Loss changes in radial diffusivity and diffusion anisotropy
Journal of Magnetic Resonance Imaging, 2008Co-Authors: Yuchun Lin, Jiunjie Wang, Yauyau WaiAbstract:Purpose To prospectively compare diffusion tensor imaging (DTI) measures of axial diffusivity (lambda parallel), radial diffusivity (lambda perpendicular), mean diffusivity (MD), and fractional anisotropy (FA) along the auditory pathway of patients with sensorineural Hearing Loss (SNHL) and normal controls. Materials and methods In 37 individuals with SNHL and 10 healthy controls, two regions of interest (ROIs) positioned along the auditory pathway-the lateral lemniscus (LL) and the inferior colliculus (IC)-were investigated bilaterally using diffusion tensor imaging at 3 T. SNHL patients were divided into three groups: patients with bilateral Hearing Loss, patients with unilateral Hearing Loss, and patients with Partial Hearing Loss. DTI measures (lambda parallel, lambda perpendicular, MD, FA) of both ROIs were determined in all subjects. Results The FA value was reduced and the lambda perpendicular was increased both at the lateral lemniscus and the inferior colliculus of patients with SNHL compared with controls. Similar changes were seen between the ipsilateral and contralateral LL and IC for patients of unilateral profound Hearing Loss. No changes were observed in any other parameters. Conclusion In SNHL patients DTI showed a high radial diffusivity that consequently led to a decreased fractional anisotropy in the LL and the IC.
