‘Rich user experience’ is a pattern of web 2.0 generation. In particular, Web 2.0 provides an environment of network that users using nowadays and people call this environment as ‘User interface.’ As Tim O’Reilly, the founder of media, mentioned ‘Innovation in assembly’ is the generated data can be re-used by the users. However, the issue is how users can explore and reuse the data. For example, when you flip a light switch, the light goes on. In this case, ‘switch’ can be the interface to approach the electronic units of light system. Users need the environment to approach data as well.
As mentioned above, User interface, the environment to approach the data, is the main factor of ‘Rich user experience.’ Simply, Rich User experiences are the transfer of using applications installed on the desktop to web based applications. Those applications have their own interfaces and these interfaces are composed of the computer scripts such as HTML5, JQuery, Adobe Flash(Javascript2.0), AJAX, CSS, and PHP. In particular, AJAX, a combination of XML and JavaScript is uprising technology of Rich User Experience.
