Development of Audiobook Interaction Design for People with Vision Impairment Based on User-Centered Design Approach

People with vision impairment have fewer sources of information than normal people because of the limitation to accessing information with their sight. As a result, this leads to an information gap. The use of audiobooks has become a way to lessen the gap. An audiobook is a recording of a book that is read aloud by the narrator. With the audiobook, a person can access the information contained in a book using his hearing. However, audiobooks have not been widely used and are still not common in developing countries, including Indonesia. This study proposes the development of an interaction design for an audiobook on the Android platform. The design is proposed using a User-Centered Design (UCD) approach that involves the predefined user in the development process. The design process begins with collecting data through questionnaires and interviews. From the data, we design two prototypes, i.e., a low-fidelity prototype and a high-fidelity prototype. These prototypes are tested on the predefined user to analyze the task completion rate, single ease question (SEQ), and system usability scale (SUS). The post-test questionnaire is additionally given to ensure the prototype has met the targeted usability and user experience goals, i.e., effective to use, easy to use, and helpful. Based on the evaluation of the test results, the proposed design has achieved the targeted usability and user experience goals.
