Discussion

Much has been written about human-computer interaction and the importance of the user interface. The overall key is to be “user-centered.” When designing your web site, imagine the experience of several users – from young students, to experienced web users, to the elderly. The interface must be immediately accessible for all visitors.

Key elements of a user-friendly interface include icons, buttons, knobs, and the “email this page” or “print this page” functions.
