| Summary: | 碩士 === 國立臺灣科技大學 === 設計系 === 105 === The progress and wide application of mobile devicess in terms of software development, hardware performance, and wireless transfer technology bring the pre-inexistent possibility and market development for the creation of track spending application. It also has an impact on the aesthetic degree of visual interface. Therefore, how to make the user enjoy a good interface usability when using the track spending application of mobile devices becomes the objective of this research study. Hoping that the user can enjoy the process of task operation and achieve the effect of usage pleasantness and continuity of use.
The major research objective is to explore the present usage situation and future possible developmental direction for the interface design of track spending application of mobile devices. A two-stage research processes were conducted to help investigate the interface usability and user experience: (1) Pilot experiment: Through three track spending applications with high download rate. A series of pilot experimental task operations were conducted and time-based performance was recorded to help obtain detailed knowledge of different factors affecting current track spending applications in terms of interface functions. (2) Confirmatory experiment: Through literature review and the integration of the results obtained by the experiment in the first stage, the research conducts interface design simulation. The simulated interface adopts a 2 (main screen style) x 3 (function menu position) factorial experiment. The main screen style is classified into two levels: 1. Tabbed main screen; 2. Image main screen. The function menu position is classified into three levels: 1. Function menu on the left of the screen; 2. Function menu on the bottom of the screen; 3. Function menu popping out from the middle of the screen.
The research results indicate that: (1) The participants of the “image main screen” give higher ratings than those of the “tabbed main screen” ; (2) The rating of “function menu on the bottom of the screen” is slightly higher than that of “function menu on the left of the screen” and “function menu popping out from the middle of the screen” ; (3) The experiment sample that combines the “image main screen” and “function menu on the bottom of the screen” has the operation mode of rapid recording of personal instant consumption. It can reduce the thinking and reasoning time for the participants as well as the error rate and frustration feeling of their usage of track spending application. In addition, it facilitates the participants to have a quick understanding of the whole operation mode, which is more friendly and direct. In addition, “function menu on the bottom of the screen” helped the user find his/her needed function quickly. Therefore, its satisfaction rating is higher than other experiment samples. Based on the results of the research, relevant applications and further research can be made in future studies.
