Modeling user interface design for panic button application for deaf people using user-centered design method

Abstract

An emergency can occur at anytime, anywhere and at anyone. The local government offers an application called “Panic Button” as a solution to these problems. This application aims to help people who experience or see emergency conditions so that they can be followed up by the authorities. However, this application has not been targeted for disability users. The procedure for using this application still has weaknesses that make it difficult for users with hearing loss, especially when an emergency event is confirmed. Normally, emergency events confirmation uses telephone calls to the incident reporter (user). This confirmation method is a big problem for those users with disabilities to be able to confirm the details of emergency events. In this research, a user interface re-design was carried out at the application interface to be able to accommodate the users necessary. The user interface modeling is done using the User-Centered Design (UCD) method to produce a user interface design that suits the user’s characteristics and limitations. USE Questionnaire was used to test the resulting prototype and results in a usability value of 87% with an excellent category after the third iteration. These results indicate that the results of the re-design that have been done have met the needs of the deaf, with the use of appropriate communication for people with hearing loss so that they can confirm emergencies properly.
