Designing 3D Printed Audio-Tactile Graphics: Recommendations from Prior Research

3D printed audio-tactile graphics are interactive materials aimed at the accessibility of people with visual impairment. There is not yet a consensus on how to design 3D printed audio-tactile graphics and most publications on this topic follow an empirical approach, experimenting first and learning with the process. However, these research publications show meaningful knowledge that can serve as the base for a set of compiled design recommendations. The goal of this paper is to present recommendations that were analyzed and extracted from 32 publications found in a systematic literature review. In total, 57 recommendations compose the set.
