In Don Normans 2003 TED talk, I have got the idea that a good design even it is useless or ugly, people can get the story and have fun from it. This is the way how design impact people to enjoy their life. In this video Don Normans has mentioned about 3 levels of emotional design, which are Visceral, Behavioural and Reflective.
Human is emotional animal, when human choose to buy things, not just think about the function, also mind on the outlook, packing of a product, that’s why designer will keep designing the same function product, but with different outlook, different color, shape is also a point that can effect people to choose it other than the simple product.
When customer but a product, they will attract by something that is fun or outstanding shape or color other than useful, for example iphone4, early in 2010, iphone4 have been sell out, even people got iphone 3gs on there hand, because of the better shape, quality, people will choose to but iphone4, iphone4 only got black color in the early half year of 2011, start from May Apple start to sell out iphone4 white color, people who are holding black iphone4, still spending money to buy a white version, why? This is emotional, some people prefer white color more, but before they choose white color, they prefer the function of iphone4.
People mood will also effect the customer and the designer, red [exciting, angry], green [peaceful], blue [sad, relax], colorful [happy]. Depends on the mood, the outcome of the design will be effect by the designer, he product that a customer will buy will be different.
A length of a design life, not only because of its own time, more is how much people love the design the product. People will increase the frequency and time of using a product because of the emotional and love, while using it in the process, will bring us happy and pleasure, which is the value of emotional design.
