PSE Flashcards
What’s habituation?
Information is so overwhelming it gets ignored
What’s Attentional blink?
Attention overloads because of the pace information is presented
What’s Familiar perceptual patterns or frames?
It occurs when people are so used to UI layout they navigate the layout automatically.
What’s Contextual Biasing?
Impacting your perception with contexts its something is presented.
Perception-based by future?
Guide - Sample what we need from world
Filter - things unrelated by our task gets filtered out unconciously
Mechanism behind influencing our perception?
Influencing - pulling information that we want
Sensitising - priming our perception to be especially sensitive to what we want to see
Biased perception & Design
- Avoid Ambiguity 2. Be consistent. 3. Understand the goals
Human perception is biased by:
Experience, Current Context and Our Goals
Our perception of objects/events is based on parts…
Our perception of parts is based on Whole
Perceptual system causes us to misperceive certain…

Name 6 Gestalt Principles
- PROXIMITY
- SIMILARITY
- CONTINUITY
- CLOSURE
- SYMMETRY
- FIGURE GROUND
- COMMON FATE
Proximity
Distance between objects affects our perception of weather and how objects are organised into groups
Similarity
Similar-looking objects appear grouped
ex. emails
Continuity
Our visual system tends to resolve ambiguity in filling the missing data
ex.slider control
Closure
Our visual system automatically tries to close open figures to perceive them as a whole
ex.collection of documents
Symmetry
Our visual system automatically organises and interprets the data to simplify it/giving it symmetry
ex.sorting a table
Figure/Ground
Our mind separates the visual field into the figure and ground.
ex. pop up info
Common Fate
Moving object. PROXIMITY and SIMILARITY, objects that move together are perceived and grouped as related.
Presenting info in a structured manner makes it
Easier for people to scan understand and remember. Eliminates the need for words and repetition.
Use visual hierarchy…
Break content into sections
Hierarchical structuring of information…
Helps people with impairments
What is CHUNKING?
Separating data into chunks make it easier to scan and remember.
Our vision is to optimised to detect…
contrasts(edges), not brightness
