UCD is constructed around the user and user needs. Each iteration of the design process is illuminated with user’s presents throughout researches, interviews, and testing. This approach allows for creating highly handy and usable products.
The distinguishing feature of UCD is that it places the user at the center of development, accounting for his or her desirable scenarios of interaction with the product. Therefore, the user will not need to correct his behavior to get used to the product specifications.
