Introduction to User Experience Principles and Process (Week 3)
Visual Perception (Part 1)
Useful view of view is small
5 degree of focus
How we see
Saccades
Meaning it doesnt mean that when we put something on the webpage users will look at it
F-patterns
Focus on visual perception
How its works
How to deliver graphic/visual efficiently to users
Principles
1.Making important information and action visible
2.Leveraging "the read" - F pattern
3.Did people actually see what we put there? - Conducting usability interviews
How human take in info about the world?
Six senses (Sight,Hearing,Smell,Taste,Touch,Consiousness)
Visual perception (Part 2)
Making sense of the visual field
How we process vidual information?
Patterns
Proximity
Closure and continuation
Pattern Identification (Gestalt Principles)
Symmetry
Similarity
Common Area
Common Fate
Objects
Identify the object
Interpret object that we recognise
Features
Slope
Length
Angle/Line's angle
Texture
Shade/contrast
Motion
Colours
Detection of features like the following:
Principles
2.Use Gestalt Principle to organise like items
3.Use Gestalt Principle to organise for skippability
1.Use "pop out" (primitive feature) to attract attention or the absence of it to divert attention
Memory (Part 1)
How information is being perceive and whether did we remember it?
What happened to information after we process it?
From senses to memory
Perception
Whatever is perceived is available but only brieftly (a few seconds)
Short-term memory
Stored for only a few seconds.
Sensory register
Requires attention. A small amount of what is available it actually perceived
Long-term memory
A relatively small amount of information is "learned" and vast amount of information is actually lost (Stored for minutes to years and decades)
Short-term memory
Information that is not retained is lost
"retained" means committed to long term memory
also know as "learning"
Principles
Give users tools for reducing options eg. filtering
Don't expect users to memorise stuffs
Keep list of options short eg. short drop-down list
Limited Capacity
"magic number" 7+-2 ~Miller's Law, 1956
4+-1 ~Cowan, 2001
Memory (Part 2)
Long-Term Memory
Anything remembered for more than a few seconds
Anything that are "copied" from short-term memory to long-term memory is called "learning"
Transfer to long-term memory
Association
Association memory. "Schema" - a network of related concept
Easier for user to remember with association by association to the schema that they already have.
Repition
Memorissation. "Elaborative rehearsal" - expanding effort to commit something to long-term memory
Likelihood of remembering
Strength of association
Regency
Frequency
Principles
2.Prefer recognition over recall whenever possible
Eg. Google search auto-complete features (we can recognise the search items)
1.Learning willl work better if learner can fit into a schema
Leverage standards and consistency eg. google spreadsheet
Avoid asking users to memorise stuffs eg. avoid password with a lot of requirements
Use Metaphor eg.shopping cart metaphor
