Usability Study Of Populor Science And Tour Guiding App For Chenshan Botanical Garden

With the development of mobile Internet, the progress of APP industry is fast, APP is quietly changing our lives. According to statistics, since2011, people spend time on the APP has exceeded webpage. However, the quality of APP is patchy, a excellent APP provides users a new experience, a bad APP brings users a lot of trouble. It’s glad to see that more and more design teams realized the importance of usability. In fact, the core of the usability is the design concept of "user-centered ", in an age of web2.0, users are not only user but also products creator.Current research on usability is mainly about the system and web, APP as an emerging industry, related studies are rarely, almost no systematic research methods, at home and abroad. With the APP is becoming increasingly important, the studies of APP usability is an area where need to be perfect. Through the study found that there are many similarities of web and APP, so the usability study on web has important reference value, this article use related outcomes as the study basis. By analyzing the similarities and differences between web and APP, according to the design process and user APP experience factors, summed up a research model of APP usability. Firstly, have a user research before design; Secondly, in the design process should always adhere to the concept of the user-centered design, and reference on the usability principles of APP design; Thirdly, APP design process should follow the way of "design-test "; Finally, the finished product still requires constant testing and optimization, so that keeping vitality.Apply the APP usability model to the APP design project of Chen Shan Botanical Garden to verify its validity. In the stage of the user research, first used the method of focus groups, questionnaires, interviews and behavioral observation to obtain user requirements, and then through card sorting, personas models and task analysis to refining user needs, provide the basis for the design.Stage in low-fidelity prototype, A/B testing is used to determine the interactive mode of "basic information of the Chen Shan Botanical Garden ". In the Stage of high-fidelity prototype, using heuristic evaluation which based on the principles of "APP design usability" find and optimize the usability problems. And then do the usability testing experiment for completed high-fidelity model, with the auxiliary method of thinking aloud and questionnaire. By analyzing the usability testing results, statistical survey results, summarized the35usability issues and prioritize usability problems. According to the priority of usability issues and the actual situation on the Chen Shan Botanical Garden APP, optimized the four aspects of information system, interaction mode, visual design and functional defects, increased the usability of the APP of Chen Shan Botanical Garden.
