Design of Translator Android Application for Sign Language and Indonesian Using User-Centered Design Approach

The lack of knowledge about sign language resulted in normal students having difficulty communicating with Deaf students. The same is true when knowledge of Indonesian oral language by Deaf students is also minimal. From this problem, an Android-based application was designed to translate between sign language and Indonesian to facilitate normal students and Deaf students to communicate. The design of the application uses the User-Centered Design approach, which is a method that focuses on the user so that the design process from the beginning to the end involves the user and the application evaluation is emphasized on usability and user experience goals. The results of the design of Android applications are in the form of high-fidelity prototypes so that applications can be operated by students. The usability test results of the application design show that evaluation of usability and user experience goals get a value above the average System Usability Scale (SUS). Therefore, the results of the application design can be said to be successful and meet the needs of users with each score, namely effective to use 4,8, efficient to use 4, easy to learn 4,4, easy to remember how to use 4,6, helpful 4,8, and satisfying 4,8. However, further development can continue to be made so that interaction, interface, and translation system functionality of the Android application can be better and more helpful for users to be able to communicate with each other.
