User-centered Design(UCD) is becoming fundamental issue in designing any system for human.The term 'user-centered design' originated in Donald Norman's research laboratory at the University of California San Diego (UCSD) in the 1980s and became widely used after the publication of a co-authored book entitled: User-Centered System Design: New perspectives on Human-Computer Interaction (Norman & Draper, 1986). Norman built further on the UCD concept in his seminal book The Psychology Of Everyday Things (POET) (Norman, 1988). In POET he recognizes the needs and the interests of the user and focuses on the usability of the design. He offers four basic suggestions on how a design should be.
