Developing iconographic driven applications for nonverbal communication: A roadside assistance app for the deaf

Abstract

Touchscreens allow interaction with icons and buttons for executing applications or selecting information. This can be used for non-verbal communication, enabling the deaf to communicate without the need for sign language translation and with a richer context than just using text. This paper explores the development process of iconographic driven applications for nonverbal communication following a user centered design approach. MyCarMobile, a mobile application intended to facilitate the communication of the deaf with roadside assistance services, is introduced as a case study. The application follows the iconographic driven interaction model allowing users to describe an occurrence, through the interaction with icons and buttons in a touchscreen device. Based on the implementation of the case study application and previous work a set of guidelines for implementing iconographic driven applications is proposed. © 2014 Springer International Publishing.
