Abstract
Abstract: Satisfaction is an important usability attribute in developing a courseware which involves end users. Measuring satisfaction among hearing-impaired students is different than measuring it among common students because they learn using sign language and have different learning styles. An educational courseware for hearing-impaired students is employed to measure this. The courseware uses the Augmented Reality technology and it is called PekAR-Mikroorganisma. Hence, this article focuses on the methodology of measuring and the attributes that contribute to users’ satisfaction. An adaptation of the System Usability Scale was used to identify the satisfaction value. Fifteen hearing-impaired students were employed as a case study. Findings show that the satisfaction level in using PekAR Mikroorganisma is high. It is hoped PekAR-Mikroorganisma can help the hearing-impaired to understand lessons better through the enhancement of their comprehension on abstract concepts.
