With the advance of mobile computing and wireless technology, a user’s intent to interact with the interface of a mobile device is motivated not only by its intuitional operation, but also by the emotional perception induced by its aesthetic appeal. A graphical interface employing icons with suitable visual effect based on the users’ emotional perception plays an essential role in determining the possibility of users' interaction with an interface of mobile device. This study commences to develop an integrated design approach based on Conjoint Analysis and TOPSIS Algorithm to the visual effect of icon design. The "Facetime App" icon is chosen for illustration purposes. A series of evaluation trials are then performed to establish the correlation between the icon visual effects and the users’ image perceptions of the icon. The integrated design approach can assist designers obtain effective information to develop the icon candidates of various visual effects so as to match the demands of multiple users’ image perceptions. Although this study takes just the "Facetime App" icon as an example for illustration purposes, the integrated design approach is equally applicable to various types of icons shown on the interface of mobile device.
