Replicating User Interface Designs for Low-Literacy Populations in Cape Verde: An African Perspective Study

User interfaces designed for low-literacy populations often face challenges in effective communication due to language barriers and limited reading skills. The methodology involved a structured questionnaire survey administered in both Portuguese and Creole. Data analysis used logistic regression models. A significant proportion (75%) of respondents preferred visual icons over text-based instructions, indicating the need for more intuitive design elements. User interfaces designed with visual cues were significantly more effective than those relying solely on textual explanations among low-literacy Cape Verdean populations. Future studies should focus on iterative testing and user feedback to continuously improve interface designs tailored for diverse literacy levels.
