If you don't notice an interface then you know it's well designed. The interface is the "location" where person and computer meet. Netscape Navigator and Internet Explorer, two popular web browsers, have graphical buttons and controls to allow for navigation on the Internet. The icons of computer operating systems like Windows 98 or the Macintosh OS 9 are part of a graphical interface. Your web site's interface (hypertext and image links) should allow others to access content transparently—without frustration.
