Arabic Sign Language

Sign language is the major means of communication for the deaf community. It uses body language and gestures such as hand shapes, lib patterns, and facial expressions to convey a message. Sign language is geography-specific, as it differs from one country to another. Arabic Sign language is used in all Arab countries. The availability of a comprehensive benchmarking database for ArSL is one of the challenges of the automatic recognition of Arabic Sign language. This article introduces KArSL database for ArSL, consisting of 502 signs that cover 11 chapters of ArSL dictionary. Signs in KArSL database are performed by three professional signers, and each sign is repeated 50 times by each signer. The database is recorded using state-of-art multi-modal Microsoft Kinect V2. We also propose three approaches for sign language recognition using this database. The proposed systems are Hidden Markov Models, deep learning images’ classification model applied on an image composed of shots of the video of the sign, and attention-based deep learning captioning system. Recognition accuracies of these systems indicate their suitability for such a large number of Arabic signs. The techniques are also tested on a publicly available database. KArSL database will be made freely available for interested researchers.

This study reports on the experiences of teachers of the deaf and hard-of- hearing students in a special needs high school for the deaf in Eswatini. The study adopted a qualitative approach and was exploratory in nature. Participants comprised of eighteen (n =18) purposively sampled teachers of deaf and hard-of-hearing students. They participated in individual in-depth and focus group discussion interviews on the teaching and communication aspects with deaf and hard- of- hearing students. Data were also collected through documents review. Credibility and trustworthiness of data were established through member checks. Data were thematically analysed for important meanings. Teachers reported to experience gaps in professional competencies to teach the mainstream curriculum for which they needed further education. Variation in sign language impacting learner engagement hindered teachers’ communication with the deaf and hard-of-hearing students and their parents. Teachers reported to have in service professional training needs which included collaboration, consultation, assessment instruments and language skills. The findings have important implications for policy and practice in educating the deaf and hard- of- hearing students and for interpreting previous research. There is urgent need for the country to consider having a standardized sign language which could enhance positive teaching and learning outcomes as well as social integration for the future lives of these students. Understanding experiences of these teachers from the lived cultural milieu are important for the design and implementation of programmes for supporting the deaf and hard- of hearing learners, their teachers and parents.

Perceptual Function

In this study, we investigated the perceptual function of deaf/hard of hearing children. The sample of the study consisted of 58 pupils aged 8-13 years old (3rd-6th graders) with severe (60-90 db) or profound (90 db and above) neurosensory hearing loss – pre-lingual with or without cochlear implants. Children with co-morbidity (intellectual disabilities, syndromes, autism, motor disorders, etc.) and children with post-lingual deafness/hearing impairment were excluded. In order to investigate their perceptual function, the Perceptual Functionality Criterion was used. The results of the study show that deaf/hard of hearing participants exhibit a “sporadic” profile regarding the general perceptual functionality. In particular, the participants were found to perform similarly in terms of visual-perceptive skills, while there was one exception, i.e. their visual-motor skills were worse. Higher scores have been shown in the domain of kinesthetic and tactile perception and lower ones regarding vestigial perception, especially in terms of the sense of balance. In addition, the perceptual function was investigated among the cochlear implant participants and those with conventional hearing aids. The results showed no significant differences between the two groups regarding the perceptual function, although the visual perception was found to be significantly better among the users of conventional hearing aids relative to cochlear implant users. Finally, the perceptual function was investigated in terms of the main method of language/communication used. The data indicated that participants, regardless of whether they use sign language, total/bilingual or oral communication, performed roughly similarly on the test variables. Among the different types of main method of language/communication, statistically significant differences were absent, though regarding the visual and kinesthetic perception sign language users outperformed the users of oral communication.
