3、ic industry press,2003),4. or in a shorter word Interaction design is behavior of the man-made products , environment and the system Alan, Cooper., About Face 2.0: The Essentials of Interaction Design,( Beijing :Electronic industry press,2005),27. . The characteristic of it is that the products are
4、easily to be learned, effect to be used, and it can provid users with comfortable user experience Jennifer, Interaction,2. But many interaction design which based on software run in the opposite direction with the nature of interaction design. It is true that we enjoy convenience the software takes
5、to us, but at the same time as Alan Cooper said Computers are invading every aspect of our lives. computer and its stupid ways of communications are everywhere.

Follow the users state of mind, behavioral pattern to consider the products. As Alan Cooper said when the designers actual is done well, the users ca
12、n not feel there are designers. Alan, Inmates,188. We should avoid to do the bad interaction design. But what is the bad interaction design?
