Abstract— Identifying dyslexia among Malaysian citizens, especially children nowadays is a prominent issue. The usual practice of dyslexia screening tests in the Malaysian school system is by teacher's observation and intervention. However, this is usually time-consuming, less accurate and lacking additional supporting tools. Moreover, dyslexic children enrolling in a normal education system will encounter many problems for the teacher and the children themselves. A Malay language mobile-based application for a dyslexia screening test named Kiddo Disleksia has been developed to solve this issue. However, it has not been tested in terms of Quality of Experience (QoE) as well as usability. Therefore, this research aims to test the QoE level of Kiddo Disleksia and also to compare the traditional dyslexia screening test with Kiddo Disleksia in terms of usability. To test the QoE, several special education teachers are required to rate Kiddo Disleksia using Mean Opinion Score (MOS). Ten children were tested using Kiddo Disleksia and 80% of them recognized as dyslexic. This result also similar with the traditional paper-based screening test. Therefore, the Kiddo Disleksia application is considered reliable for dyslexia screening tests for children. For QoE, the results show that the mean values of MOS are 3.9 and above. Therefore, the quality of experience during dyslexia screening tests can be enhanced using Kiddo Disleksia. Keywords—Dyslexia Screening Test, Mean Opinion Score, Quality of Experience, Usability. I. INTRODUCTION yslexia is not a disease, but it is an internal disorder in children that prevents language development during the learning process [1]. Children with dyslexia are usually smart and hardworking. However, they have difficulties in recognizing words, letters, and other symbols, thus, having problems in reading, writing, as well as speaking. In Malaysia, there are around 5 to 10% of its population is born with dyslexia symptoms [2]. Dyslexia has been acknowledged by the Ministry of Education Malaysia as one of the Specific Learning Disability and establishes a Special Education Program for children with dyslexia [3]. The normal practice of dyslexia preliminary screening test in the Malaysian school is fully conducted by the school teacher. Identifying dyslexia among students manually is a difficult task. Students must be identified earlier whether or not are dyslexic. However, it is usually impossible to identify dyslexic children in the early stages of primary school. One of the most dyslexic symptoms among children is having difficulties learning letter names and their sounds [4]. They also always spell with unpredictable and inconsistent letters. Dyslexic children are prone to writing letters and numbers backward, such as '6' instead of '9' or 'b' instead of 'd.' Due to these difficulties, dyslexic children could not understand what has been taught by their teacher [5]. These difficulties are worsening if dyslexic children are not identified earlier. Therefore, teachers’ knowledge in identifying dyslexic children is crucial.
