Comparative Study on the Usability of Navigation Style in Iteration Process of Mobile Software

Based on the summary analysis of the development rules of mobile App iteration process, this paper selected six popular mobile phone software whose main navigation styles are iterated from drawer navigation to tabbed navigation, conducted a usability test of six old and new version software through the eye movement experiment, and compared the usability differences before and after the change in navigation style to study which navigation style is more suitable for mobile phone software. It carried out a comparative analysis of the usability of six old and new version software based on task completion rate, task loss degree, the completion time of search task (gaze time), the number of fixation points in browsing task, the time of entering ROI for the first time in browsing task and the time of triggering ROI for the first time obtained from the experiment, combining participants' subjective satisfaction questionnaires and in-depth interview after the experiment. The results showed that the use of tabbed navigation software is better than that of drawer navigation software, and the usability difference caused by this navigation style is not related to the software type. In addition, this paper summed up usability problems in navigation design according to the experimental results, and provided a reference for interface designers and interaction designers to choose the navigation style and design interface.
