Abstract

At present, there are numerous usability problems in the long-term rental application in Chinese market, including unreasonable interaction design problems and irregular interface design problems. The usability elements and the interaction design principles of the long-term rental application are proposed to support the usability improvement. The usability elements, namely effectiveness, efficiency, satisfaction, learnability, security, and versatility, and the interaction design principles include meeting user mental models; focusing on the analysis and design of different touchpoints; completing information searching path; reasonable information display methods. User behaviors and usage preferences are explored through focus group, non-participant observation and questionnaire survey. One long-term rental application is redesigned to follow the interaction design principle. For usability testing, the measured person uses the application before and after the improvement, counting the usability score and level to determine whether the redesign has been improved. The principle of interaction design can improve the interaction design level and achieve the goal of improving usability of the long-term rental application.
