Usually, Web-based graphical user interfaces (GUIs) are not specifically tailored for different devices with touchscreens, such as smartphones, where interaction is affected mainly by screen size. Moreove, they generate a profound impression of the overall quality of a Web site. The evaluation was conducted using 12 users of ages 18 to 24.
