Augmented Reality Enabled Development of the SIBI Alphabet for Deaf Communication

Communication with deaf people requires a particular language, namely sign language. The Indonesian Language Sign System (SIBI) is used in the school curriculum as the official sign language for the deaf in Indonesia. For communication with deaf people to be smooth, it is necessary to provide convenience for the community to learn sign language. This research aims to produce an application that can be used to help deaf people learn sign language. The target users of this application are deaf students in the seventh grade of Junior High School (SMP). The Isyarat Kita application is developed using the Multimedia Development Life Cycle (MDLC) method, a rigorous six-stage process that ensures the quality and effectiveness of the application. This application presents three-dimensional objects and hand gesture animations that demonstrate the letters of the SIBI alphabet from various angles with rotations of up to 360 degrees. This application also provides an SIBI letter and word recognition video feature. Alpha testing shows that all functions work as designed, while beta testing using the End User Computing Satisfaction method results in the Very Satisfied criterion with a score of 93.9 percent.
