Using a systematic literature review, this review examines existing studies on the design, usability, user experience (UX), and adoption of computer applications designed for illiterate and semi-literate users. A total of 45 articles were reviewed from an initial set of 527 articles following an inclusion-exclusion criterion. As outcomes, in addition to synthesizing the present research activities, this review revealed a total of 16 design considerations or guidelines that may improve the usability, user experience, and adoption of software systems to illiterate and semi-literate people. The revealed design considerations were also investigated concerning the country context and application platform. Finally, a set of good rules categorized into five perspectives (uses of text, interaction pattern, uses of pictography, uses of audio-video, and info-architecture) were revealed to design and evaluate software systems to make them more usable to the illiterate and semi-literate users. The review also reveals future research opportunities that include: exploring the design considerations with respect to context-dependent applications; investigating the design requirements for public IT (e.g., vending machines and kiosks) systems; adopting the semiotic concept in UI design; developing a new usability evaluation framework; and exploring the effects of multi-platform and cross-country app design. Thus, the implication of this study is to discover the research gaps and provide future research directions aiming to design applications for illiterate and semi-literate users with enhanced usability and UX.
