Week 6 | USER-CENTERED DESIGN

The 3 main principle of human perception were Chunking, Visual variables and Gestalt

Graphic Design Guidelines are balance, simplicity, contrast, alignment and white space.

So what is simplicity?

Simplicity is not simple as you were lazy. To design something simplicity needs a process of elimination and delete whatever that is unnecessary. Everything that we eliminated should have a good reason and all the remain things also should have reasons. 'Foreshadowing' is what they called it in film.

What is chunking?

Chunking ia bite size of easy storage. The elements of PERCEPTION plus MEMORY equal to CHUNKS. Forming chunks in working memory depends on how information is presented.

What is contrast?

Make information stands out and shows the differences along a visual dimension.

What is visual variables?

Encoding DATA plus DRAWING. It was used for communication. There are two types of visual variables which is :

1. Selectivity

+ degree of a single value selected from the entire visual field

+ most variables are selectivity

+ it's hard to pick out triangles

+ shape are not selective

+ locate objects at a glance

2. Associativity

+ opposite of selectivity

+ something that blends into one another

What is white space (negative space)? 

A space between 2 or more elements like text, graphics or other elements which helps separate them from one another.

What is balance?

It acts as a gravity of the whole design making the design visually balance by putting certain form of elements in the correct position.

Three types of balance in design :

+ Symmetrical balance

+ Asymmetrical balance

+ Radial balance

What is alignment?

Positioning of the images and text so that they are in line with each other to group items, to create visual connections or to organize page elements and to create order.

What are Gestalt Principles?

+ Proximity

+ Similarity

+ Continuity

+ Closure

+ Area

+ Symmetry

UCD 

System-Centered Design - User-Centered Design (UCD)

It shifts focus from the designer of the application to the user of the application.

In Wikipedia, UCD 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. User-centered design can be characterized as a multi-stage problem solving process that not only requires designers to analyze and foresee how users are likely to use a product, but also to test the validity of their assumptions with regards to user behaviour in real world tests with actual users. For example, the user-centered design process can help software designers to fulfill the goal of a product engineered for their users. User requirements are considered right from the beginning and included into the whole product cycle. These requirements are noted and refined through investigative methods including: ethnographic study, contextual inquiry, prototype testing, usability testing and other methods. Generative methods may also be used including: card sorting, affinity diagramming and participatory design sessions. In addition, user requirements can be inferred by careful analysis of usable products similar to the product being designed.
