Chapter 9 & 10
Wireframe goals
high level objectives, ease of use avoiding errors safety , can be stated for all users work roles user class of specific task
Targets
a collection of information defining the useage goal metrics and other info
intermediate design
informative objects browsing etc , main focus on screen layout and navigations structure , click through prototype
ideation iteration
lighting fast, loosely structured, for the purpose of exploring design idea, prototype- role of played by scenes
Metrics
measure able performance based values taken during benchmark tasks
metric levels
Base line , target
detailed design
annotated wireframes evaluate and iterate detailed designs to refine wireframes
Baseline level
benchmark for current version of the system
work role
capture high level goal of user, ticket buyer
measure
caputers a measurable aspect of a goal
conceptual design iteration
critique and compare multiple design concepts, Sort out best ones, weigh concepts feasibility. prototype low fidelity
contextual
data consolidation
contextual analysis
data interpretation
measuring instruments
description of the method oft Providing values for a measure
wireframes
detente representation medium for interaction design at this stage
Design refinement iteration
proto type usually medium to high fidelity , evaluation
user class
provides detailed look at user
target level
quantitative statement of an expected value, choose values that are realistic, keep in mind reading time I physical limits, physical limits, thinking Times
Contextual Inquiry
raw Work activity data
common subject metrics
reported ease of use, Feature usage , reported fatigue.
wireframe one used for
representing design objects / navigation
common objective metrics
task completion time, no of errors, error recovery time, % time Spent on each subtask, no of insigne/ frustration, learning curve, critical incidents and probs
metric
the value derived from the measuring instruments for UX
intermediate design iteration
to arrive at one intermediate design For layout and navigation, prototype - low fidelity , fully interactive-high Fidelity
detailed design interaction
to decide screen design and layout details, includes "VisSud camps", for Look and feel
Success/ progress of the new system evaluated using
user experience goals, metrics targets
Choosing a target element
workrole, user class, measure , measuring instruments, metrics
