User Interface• User Interface is a linkage between a human and a device or system

that allows the human to interact with that device or system. • The user interface provides means of :

– Input, allowing the users to manipulate a system – Output, allowing the system to produce the effects of the users'

manipulation.• Currently, the following types of user interface are the most common :

– Graphical User Interface (GUI) accept input via devices such as computer keyboard and mouse and provide articulated graphical output on the computer monitor.

– Web User Interface (WUI) accept input and provide output by generating web pages which are transmitted via the Internet and viewed by the user using a web browser program.

Good Interaction Design

• To improve the usability of an application it is important to have a well designed interface.

• Ben Shneiderman's "Eight Golden Rules of Interface Design" :– Strive for consistency– Enable frequent users to use shortcuts– Offer informative feedback– Design dialog to yield closure– Offer simple error handling– Permit easy reversal of actions– Support internal locus of control– Reduce short-term memory load

Good Interaction Design

• According to Patrick Lynch, 1995– Balancing the structure and the connection between menu or

home page and the content of the page or between graphic and the linked document.

– The purpose is to build a natural and well structured menu hierarchy and pages for users, and not to divert the usage of the web site.

World Wide Web

• With a Web browser, a user views Web pages that may contain text, images, videos, and other multimedia and navigates between them using hyperlinks.

contents to other documents stored at the site.

document users see when they enter the site. • The site might also contain additional documents and
