User Experience Flashcards
What underlies the UX?
-Processes
-Systems
Where does UX come from and where is it going?
-Marketing
-Industrial design
-Human-Computer Interaction
-Digital Business Models
What does UX require?
-Creators
-Consumers
-Power Consumers
The world according to Norman
-Discoverability
-System Image
-Affordance
-Signifiers
-Conceptual Model
-Feedback
-Mapping
Discoverability
-Is it possible to figure out what actions are possible?
-Is it possible to figure out how to perform them?
Affordance
-determine what actions are possible
-Relationship b/w properties and capabilities
-perceivable
-critical for designers
-implied by the design
-e.g. a chair, mug for coffee
the relationship between the properties of an object the capabilities of the person that determine just how the object could be used
Signifiers
-communicate where the action should take place
-Anything that may signal meaningful information
-Signify what to do
-any remark or sound, a perceivable indicator that communicates appropriate behavior
communicates where actions should take place; any mark or sound, any perceivable indicated that communicates acceptable behavior to a person
Mapping
-Relationship b/w the elements of two sets of things
-A device is easy to use when the set of possible actions is visible
Feedback
-Communicating the results of an action
-immediate, informative
Conceptual Model
-Represent our understanding of how things work
- an explanation, usually highly simplified, of how something works Framed by the affordances, signifiers, constraints, and mappings
-mental model
System Image
-Designer’s Concept
-User’s concept
-Communication is the key
what the device looks like, what we know from using similar things in the past, what was told to us in the sales literature and manuals.; perceived from the physical structure that has been built
conveys designer’s conceptual model to the user
Root Cause Analysis
-Identify the problem
-Define the problem
-Collect Data
-Identify Possible Causal Facto
-Identify the Root Cause
-Recommend & Implement Solutions/Changes
investigate an accident until a single, underlying cause is found
Errors
-Slips
-Action-Based
-Memory-Lapse
-Mistakes
-Rule-Based
-Knowledge-based
-Memory-Lapse
Slip
-Intent does not match action
-Action Based
-Memory Lapse
- an
unintentional
action
occurs when a person intends to do one action and ends up doing something else
Mistake
-Wrong Goals or Plan
-rule based
-knowledge based
-memory lapse
- failures of
planning
Memory Lapse - Mistakes v Slips
Mistakes
-errors in choosing an objective or specifying a method of achieving it
Slips
-errors in carrying out an intended method for reaching an objective
How to combat slips and mistakes?
-Understand the design and the user
-Usability testing
-Discoverability of errors
-availability of help
-checklists
-provide assistance to users through visual clues, feedback
Human Error - Slips and mistakes
slip
-understand system and goal
-correct formulation of action
-incorrect action
Mistake
-may not even have the right goal
Fixing things?
slip-better interface design
mistake-better understanding of system
Design Process: Problem/Opportunity Identification
1.Understand
-Empathize
-Define
2.Explore
-Ideate
-Prototype
3.Materialize
-Test
-Implement
Project Research - Gathering Requirements
-People
-User Experience
-Processes
-Data
Intended Users - “People”
-interviews
-observations
-secondary research
-LinkedIn, social media channels
Processes
-Primary Research
-Secondary Research
-Observation
-Interviews
Data
-go to the site or app - what is being collected?
-sign up for the mailing list - what information is generated
-Think of the processes - what data might be needed to complete them
Compiling the details
-Make a list of critical findings
-Persona map
-Data Map
-Visuals
-Collaboration tools
