The learnability principle relates to improving usability of software, performance and productivity. It was formulated mainly for the adult user group. Children represent an important user group, but fewer guidelines exist for their educational and entertainment applications. This study compares these groups, addressing the question: “Does learnability of software interfaces have a different meaning for children and adults?”. A literature survey conducted on learnability and learning processes considered the meaning of learnability across generations. Users learning software systems were observed in a usability laboratory where eye tracking data could also be recorded. Insights emerged, from data analysis, showing different tactics when children and adults approached unfamiliar software and revealing aspects of interfaces they approached differently. The findings will help designers distinguish varying needs of users and improve learnability. An additional subprinciple of learnability, „engageability‟, is proposed. Factors that make products engaging for children are different from those engaging adults. === Computing === M. Sc. (Information Systems)
