Multimodality User Interface in Mobile Technology: Increase Learning Performance for Dyslexic Students in Sudan

Multimodal user interface (MUI) plays a key role in the future of mobile technology. After having a comprehensive review of the previous researches to determine the research problem, the researcher collected the relevant data by face to face interview with dyslexia students, teachers and experts from learning difficulty domain. This research developed a multimodal user interface in mobile learning application, for dyslexic students. The Researcher implement an Arabic letter mobile application to taught dyslexic students in a Sudanese primary school. Firstly, the application was developed on android platforms. Secondly, the application implemented in students sampling of size 30 students. Finally, the application was evaluated in two stages. The first one is to evaluate the enhancement of student who was taught a multimodal user interface; the second stage is an evaluation by using the technology acceptance model (TAM). The evaluation stage show increasing in education level for dyslexia students in significant degrees. Multi-mode learning has a good effect in dyslexia students on this study, there was a significant difference between student's marks after using the mobile application in teaching alphabet letters and the student's degrees before using the mobile application, which means the multimode user interface improved the reading skills for most dyslexic students who are involved in our study.
