update my blog from today

Writing is a good way to sharpen my thought and sort my idears, so I am going to write something everyday from now .

Today I studied the information user.

In order to do better information system design, it's meaningful to understand the information user.

Users can be categorized as:

Novice users: this kind of user need simple and intuitive interface.

expert users: they need short_cut to perform their task, menus always slow down their pace.

users with special need: they need some assistive technology to help them.
