Mobile Technology and Extended Reality for Deaf People: A systematic review of the open access literature

The present study is a systematic review of the scientific literature, published between 2006 and early 2020 with open access, which aims to know the use, by non-hearing people, of mobile technology and Extended Reality, encompassing this term to Virtual Reality, Augmented Reality and Mixed Reality applications that seek to improve human-computer interaction through sensory experiences. Particularly, applications used for teaching-learning are analyzed, inquiring, among other questions, what are the didactic themes, the target groups and the sign language used. The results show a high predisposition to the use of mobile technology due to the ease of use of visual / tactile resources. There is still a reduced but promising use of Extended Reality, which allows a field of application of new contributions for the development of the deaf community.
