User-Centered User Interface Design for Educational Game: Letter and Number Recognition for Slow Learners

Children with mental retardation are children who have intellectual mental disorders with intelligence levels far below the average normal child and their social adaptation is hampered. With the limited development of intelligence experienced by slow learner children, education is needed that can train their mindset so that they can develop in such a way. One of them is by using educational games intended for children who have mental retardation. Educational games are the right solution to help improve logic and understanding of learning material in the form of attractive visual technology for slow learnerchildren. With these problems, the authors designed a prototype design of an educational game application for recognizing letters and numbers for slow learnerchildren using the User Centered Design (UCD) method. In evaluating the success of the high-fidelity prototype using the Heuristic Evaluation method. The Heuristic Evaluation questionnaire was distributed to three evaluators and processed using a Likert scale measurement. The results obtained are that the design of the letter and number recognition educational game application for slow learnerchildren meets the usability criteria which is the effectiveness, efficiency, and user satisfaction in using the application as much as 79.13% which is on an attractive scale.
