One of patterns which need to be considered for web 2.0 applications is Rich User Experience. What does Rich User Experience mean? This needs to be defined for desirable application of this pattern. Luristic says, “Rich User Experience invokes the wow! factor. It ignites emotions in users by first impressing them and then making them addicted, loyal, and contagious.” In other words, Rich User Experience is something which can incentivate more people to more frequently use services. For achievement of Rich User Experience, abundant and various services need to be provided using more executable, expanded and more intelligent client technologies. Stiles describes, “Rich User Experiences are typically a combination of GUI -style applications and multimedia contents.”
There are several technologies for achievement of this, such as XHTML, CSS, DOM, AJAX, Adobe Flex, Flash, Silverlight and so on. In particular, AJAX is a key component that facilitates this type of experience. It is not too much to say that AJAX is a collection of technologies used together to create a rich user experience. AJAX has been used by many sites without even realizing it, and those sites applying AJAX shows what Rich User Experience is well. The core of AJAX is to provide users with easier, more convenient and intuitive services, not new and complicated services.
This is the key to achieve Rich User Experience as well. For the reason, a browser plays more roles on web 2.0-based websites than on others. Now a variety of functions can be easily used on a browser without pressing any button or installing any software. One simple example is predictive text input. This saves users the trouble of typing. As many portal sites have adopted this, a quicker and easier search has become possible. 
In addition, diverse efforts for Rich User Experience not only have offered simple functions like this but also have enabled people to directly use complicated software such as Word or Excel on the Web.
Prezi.com
Prezi.com is the best example which provides users with rich experience. This is a cloud-based presentation software. In general, people may consider Microsoft PowerPoint as a presentation software. However, there are definite differences between Prezi and Microsoft PowerPoint. First of all, in the case of Prezi, presentation media can be made on the Web without installing anything. On the other hand, in order to make presentation media using Microsoft PowerPoint, that software has to be installed on the computer certainly.
In addition, the biggest difference is that Prezi provides various functions for Rich User Experience. Prezi’s stated mission is to make presentations more interesting to effectively share ideas, and it is intended to be an intuitive tool to develop and share ideas as a visual narrative. For achievement of this mission, Prezi provides differentiated services. Prezi is used as platform for bridging linear and non-linear information, and as a tool for both for free-form brainstorming and structured presentation. Furthermore, text, images, videos and other presentation media are placed upon the canvas, and can be grouped together in frames. Users can then designate the relative size and position among all presentation objects, and pan or zoom in/out among these objects. For linear presentations, it is possible to construct a prescribed navigation path as well. In particular, Zooming User Interface (ZUI) makes the presentation fun. Users can leave a deep impression on the audience when exploring ideas and the connections between them through ZUI. In other words, it enables users to make visually captivating presentations. Moreover, the Prezi system is easy to use and available across platforms, so it provides users with much convenience.
Action speaks louder than words.

Nice mini-prezi 🙂
I didn’t know about Prezi until I saw it used in the lecture and it’s a huge step forward from the traditional presentations. As for rich user experience I’d have to agree – Prezi being available online and free is great I just think more people should be using it.
Hello, Reeced.
I agree with you. That is a very useful tool. I really recommend Prezi to people. If it is used for a presentation, the presentation will be more impressive. Thank you for your comment. 🙂
I think Prezi is an interesting web tool for presentation. The fact that it is cloud based means that it will work on most computer or mobile devices that is connected to the internet. In addition, being independent of software installed on any computer ensures the layout and format of the presentation created being standardised across platforms.
Yes!! Therefore, Prezi is very easy to access. This is one of its strengths. I think Prezi is a great application which has many strengths and effectively applies various patterns of web 2.0 as well as rich user experience pattern. If you use this actually, you will be able to feel its merits surely. Thank you for your comment.
Hi there. Great post! I never really considered all of the benefits that Prezi offers, but it is quite obvious that it is using a good combination of the best ideas from desktop and network applications. The fact that it operates on a cloud system really makes it a ubiquitous service, allowing users to have a better experience. Thanks again, Brittany.
