认真阅读下列短文,根据所读内容在文章后表格中填入恰当的单词.注意:表格中的每个空格只填1个词.
     Traditionally,customers may consider more about what they buy the product for.However,the image of product and
the consuming circumstance have become the key points to attract customer awareness and stimulate their buying needs.
Frequently,customers buy goods just because they are cute,lovely and unique.With a less emphasis on functional utilities,
the experience and imaginative space are placed into an increasingly important role.The image of product is emphasized,
as well as the communication between products and consumers."Customer behavior,which appears to be focused and
directed at the object and at pleasure,in fact responds to quite different objectives:displaced expression of desire,and the production of a code of social values through the use of differential signs" (Baudrillard).The reason for image-oriented
customer behavior is probably that customers' lifestyle has been continuously virtualized by paying much attention to
"Virtual Reality".The evidences can be traced from computer games and Hollywood movies,in which customers'
preference for fleeing reality is perfectly matched.
     This change requires us to take efforts to enhance product image by integrating style,color,taste,shape and material,
and communicate with customers creatively,imaginatively and innovatively,and enable them to enjoy the distictive
experience image brings." "〔A〕need is not a need for a particular object as much as it is a 'need' for difference"
(Baudrillard).The typical example is Apple Computers IMAC,which has strong visual impact and outstanding dynamics.
By this way,customer relationship can be set up through image,and brand can be treated as living that can transform
people.Other examples commonly used are Disney Fairyland and Las Vegas,where new experience and imagination are
fully demonstrated.In sum, consumption is negotiation,a never-ending conversation held in the languages of advertising,
packaging,branding,fashion,and entertainment.
