The Influence of Illustrative Style of Icon Design on Usability and Aesthetics

After the previous study on the illustrative style of icon design, we found that the combination of different design features of icon will bring the different emotional effects to users. The next topic is how to implement our results to the interface design with other devices and confirming the influence of positive emotion which is relative to specific design feature between the user's evaluation of usability and aesthetics. For the purpose of verification, we choose a common interface of ATM in Taiwan as a target and consulted ten professional interface designers with questionnaire by Delphi method. We asked the professional designers to select half of the emotional words which were well suited to the interface design of ATM by their subjective judgment every times. At the beginning, twenty-four words are prepared. After sending email to and fro three times, we reduce the twenty-four words to two words-technical and stable. Then, according to the results of our previous study, we use six illustrative styles such as square-frame, plane-shadow, non-perspective, sharp-emboss, transparent material, and red color to redesign the icon used in the interface of ATM. Users are asked to execute some simple tasks like withdrawal, transferring account and changing password with the original one and the redesigned interface of ATM. After the task, users will make evaluation on usability and aesthetics with Likert scale method. The results will help us to explain users' satisfaction and pleasant interaction experience and how they influence the usability.
