As Internet connections speeds continue to improve, the experience for users accessing a range of services have evolved to take advantage of these improvements. This has lead to the 4th Web 2.0 pattern, Rich user Experience.
As explained by Tim O’rilley, creating a rich user experience is the process of combining the best elements to a desktop application and the online experience. This process creates a richer and more compelling experience for the users and assists in the transition from the desktop to an online model.
To explain this pattern, I have used google email service, gmail. With the gmail service, google created an online interface which allowed users to access their email. Google had taken an already existing service and developed a rich user interface with in web application.
Google have evolved this interface over the years they have been over several years and it now includes many features. These Features include,
· Simple way to send and receive emails
· Displaying documents received
· Instant messages facility
· Contact management system
· Calendar
· Task list
All of these services can be accessed from within the one user interface.
There are many other services such as Yahoo and Windows Live Mail which may offer more sophisticated appearing interfaces than the service offered by Google but, Gmail has new some web 2.0 technologies behind it.
The Ajax programming used in gmail allows the software to refresh the inbox and display any new messages without requiring the users to refresh the entire page. The use of these web 2.0 technologies to create a rich user experience has allowed Google to develop a product with many competitive advantages over competing products on the market.
