With the development and popularization of various mobile devices such as smart phones and tablets, the number of page views from mobile devices is catching up with that from desktops. More and more attention has been paid by web developers to the issue of how to develop web pages which can bring visitors using devices of different screen sizes and resolutions the best user experience efficiently in the shortest time possible. And the technology of responsive web design (RWD) features the integration of multiple platforms, which perfectly meets this demand. Therefore, the RWD technology has become major trend in the field of web development nowadays. However, as responsive websites have become more and more popular, only about half of the university/college websites in Taiwan are responsive websites. The behavior model of most of the users of the university/college websites is to search for information purposively. The main user group is young students aged 18 to 25, who are more likely to use mobile devices than other groups according to their daily life behavior model. This study selected 9 websites of art and design related departments with responsive functions as the research sample. 3 professors and domain experts whose areas of expertise are web design, visual design, and website user experience design, respectively were invited to participate in the first stage of this study. And the research method of heuristic evaluation was adopted for case analyses. During the second stage, 7 typical tasks were planned. For each task, 10 students aged 18 to 25 were invited to be the subjects of the usability test with that task. During the process, the think aloud protocol was used and post interviews were conducted for the purpose of evaluating the usability of the sample websites. After the analyses, the research findings in relation to the sample websites were summarized. It was found that there are several common problems with the use of the RWD technology in the university/college websites, including the followings: 1.How information is presented is not well-planned. As a result, users can hardly understand the information presented. Take the “works” pages of the sample websites of the art and design related departments as an example, there are pages with a lot of images but not enough descriptions as well as pages with a lot of text but not enough images. In both cases, users’ impressions when browsing these pages may be influenced in a negative way. 2.The planning and logics of the information structures and layers, and classifications in some of the sample websites are not clear enough. According to the experts, as the classifications in these websites that are not clear or do not conform to users’ general knowledge, the efficiency and learnability of these websites may be influenced in a negative way. 3.According to the user experiences in relation to the operability of the sample websites, the overall usability in the operability aspect of the sample websites with some detailed designs to optimize user experiences is higher than those without. 4.As for the menu layers and designs, some of the sample websites are too complex in terms of the layers and classifications of their menus. As a result, the learnability of the users new to these websites may be influenced in a negative way. And the visual readability is also closely related to the satisfaction with the usability. 5.The flexibility of some of the sample responsive websites in terms of switching to a different device is not good enough, so that users may be influenced and limited when browsing these websites. 6.Buttons and links are hard to identify. At first glance, the buttons and links in some of the sample websites are simply like a part of the text. As a result, users may be confused when trying to identify information and the efficiency of those websites is rather low. Lastly, based on several main aspects, including information presentation, layers and logics of information structure, user experience, menu design, readability for different layouts, and button identification, this study summarized the key factors to be considered when adopting the RWD technology to design a university/college website, as references for university/college departments which plan to build a responsive website. |
