Week 6 - User Centred Design

What is simplicity?
Simplicity is about do or show something simple but not simply, simplicity is also  something that easy to understand in contrast or something complicated. Simplicity is not something simple. For designer designing simplicity is a process of elimination and forces designer to have a good reason for everything because they have to explain how does the product works with the design. "If you cant explain it simply, you don't understand well enough" Albert Einstein

Chunking
Chunking is a type of memorizing, in psychology is phenomenon whereby individuals group responses when performing a memory task. The chunking is the combination of perception and memory. This method is to let people more easy to memorizing the subject.
For example,
4 3 3 4 9 6 5 9 3 5 7 5 7 3 7 5 8 6 7
433 496 593 575 375 867

Contrast
Contrast is a person or thing showing the differences when compared with another. Contrast is to make element stand out.The use of opposing elements, such as colors, forms, or lines, in a design an intensified the effect in a work of art. The difference in brightness between the light and dark areas of a picture, such as a photograph or video image.

Visual Variables
visual variables are used for communication by encoding date and drawing. There there are 2 ways that visual variables work on perception
-selectivity
-associativity

Selectivity
A good designer will select a better single value from the entire visual field. Visual field is to make it more attractive and get most attention from the audience by using position, size, orientation, hue, value and texture.

Associativity
Associativity is the opposite of selectivity.a picture with associate is a picture that blend image, object, colour and placement all together. In another words, the object is very hard to stand out.

User Centred Design

According to Wikipedia, User-centred design is a design philosophy and a process in which the needs, wants, and limitations of end users of a product are given extensive attention at each stage of the design process. A good design is not always satisfied customer because only customer know what they need and what they really want it. A design is a collaboration between designer and customer because designer is design for the customer so designer have to know and understand what the customer  need and what they really want with the design of the product.If the information from user is wrong,then the system will suffer. Designer have do more research of the information and different which is the correct or wrong information from the customer. Sometime designer will misunderstand the information from the customer,so one of the easiest way to prevent designer received wrong  information from customer is to have a good communication with customer.
