A systematic literature review on attractiveness and learnability factors in Web applications

User interface design is an essential element for consideration in Web application development. Usability (ISO/IEC 9126-1:2001) or operability (ISO/IEC 25010:2011) is one of non-functional requirements which must be taken into consideration when designing a user interface. Attractiveness and learnability are among the sub criteria under the operability factor. Analysis of these criteria may be used to evaluate user interface design. This study has adopted a systematic literature review method to study existing works concerning the two factors of operability. The outcome of the review provides insight into existing works on attractiveness and learnability factors in software applications generally and Web applications specifically.
