Designing a Literacy-Based Mobile Application for Adult Learners
Jennifer Hill, Rahul Simha · 2016
In this paper, we discuss the design of CAPITAL Words, an educational Android application to help low-literacy adults improve their phonemic awareness. We discuss our design choices concerning iconography, linearity, consistency, robustness, interactivity, and visibility when creating mobile software usable by illiterate users. We conducted a usability study with 11 adult learners at a local literacy center to determine how successfully users are able to interact with our interface. Results show that the majority of our design choices were intuitive for low-literacy adults with prior smartphone experience and highly learnable for inexperienced users, and that users overwhelmingly enjoyed using the app as a learning tool. This suggests that, if users are given a small amount of guidance initially, there is a high likelihood that they will be both willing and able to continue using our app independently to improve their literacy skills.
