Digital publishing is one of the national key programs. Different from traditional digital publishing models, consumers could create personal digital publications with the editing program provided by businesses and combine it with web-to-print to output solid publications. Nevertheless, the usability of online publishing software is related to consumers’ acceptance or intention of product purchase. In this case, Focus Group is utilized to screen representative online publishing software (including TinTint, Photobook, and Hypo) for evaluating interface usability, investigating users’ Subjective Satisfaction, and further proposing suggestions for interface modification. Learnability and the number of user errors are set as the evaluation indicators of usability. Within the evaluation indicators in Learnability, the results show that nine typical tasks, except for Storing, show significant difference between various online publishing software. Typical tasks of basic information of works, appending pictures, adjusting pictures, changing type version, and changing pages in the number of user errors reveal significant difference on distinct online publishing software. Regarding the evaluation of overall Subjective Satisfaction with interface, TinTint and Hypo outperform Photobook, and no significant difference appears between TinTint and Hypo. It is expected that the research model could be the application reference of interface development and evaluation in digital content industries.
