Designing user interfaces for low-literacy populations is crucial in contexts where education levels are low, such as in certain African countries. In Guinea, there is a significant need to understand how technology can be adapted to facilitate interaction with digital products. A mixed-methods approach was employed, combining qualitative interviews and quantitative usability tests. Data collection involved observing participants' interactions with prototype designs and collecting feedback through surveys. Prototype A achieved a 75% user satisfaction rate in the first phase of testing, while Prototype B garnered an 80% response rate from users who reported clear understanding of multimedia content delivery systems. User interfaces designed for low-literacy populations in Guinea showed higher engagement and comprehension when incorporating visual elements and simplified language structures. Further research is recommended to validate these findings across different cultural contexts. Developers should prioritise the inclusion of intuitive icons, straightforward text instructions, and clear audio cues in their designs for illiterate or minimally literate users in Guinea and beyond.
