Abstract. The purpose of this study is a literature research on interaction design and existing software applications for dyslectic users. This literature research will contribute a future empirical study on how we could design a reading software application together with dyslectic users to enhance their reading skills. For the purpose of this research, we initially collected 175 studies, from which we selected, reviewed and made an overview table of 71 studies organized by areas of attention. The literature research on interaction design of systems for dyslectic users resulted in a presentation and comparison of interaction design (IxD) parameters. This process indicated common dimensions and elements among IxD parameters supporting users in improving their reading skills. Finally, reviewed studies on existing software applications resulted in a focus on improving dyslectics' reading performance. Our results showed that there is a trend on developing interaction designs focused on the reading conceptual area. We also discuss dyslectics users of existing software applications complaints, which resulted in a lack of existing software applications' design and system quality.
