User Centred Design- week 6

User Centred Design

Human Perception
-Chunking
-visual variables
-Gestalt principles of grouping

What is Simplicity?
# Designing simplicity is a process of eliminiation / delete whatever that is unnecessary
# Should HAVE a good reason for everything
# In film, its called FORESHADOWING =
“Simplicity is NOT simple”

-If you can’t explain things in a simple manner then you don’t understand well enough.

CHUNKING
- Elements of perception+memory = chunks
- Bite size of easy storage
- Forming chunks in working memory depends on how information is presented
CONTRAST
- Shows the differences along a visual dimension
- Make information stands out
VISUAL VARIABLES
- Used for communication
- Encoding data + drawing

2 ways – selectivity and associativity
#Selectivity
- Degree to which a single value can be selected from the entire visual field.
- Most variables are selective
- Shape however is not selective
#Associativity
- Associativity is the OPPOSITE of selectivity
- Easy to ignore the variable / blends in the environment

Gestalt principles
-proximity
-similarity
-continuity
-closure
-Area
-symmetry

+System centred design >> System attributes first

User Centred System Design

What is UCD?
- Shift the focus from the designer to the user of application

Difficulties of UCD
Good design not always = a satisfied customer

Why?

Design always evolves along the time, thus the satisfaction is always goes higher up.

UCD is a participatory design

Problems with UCD? – misunderstandings,interviews

Users are the first member in designing process = know all the work context


Methods of involving the user
- Hard to get a good pool from the users to test the product.
- Users are not designers = Users are not always right actually.
