SYST 469 - Final
Interactive Wireframe
Used for documenting because they incorporate a level of detail that more closely matches the design of the actual webpage, thus taking longer to create. You can click and interact with the wireframe.
Independent Variable
- Products - Your Choice (Makes it Independent) - Outcomes of Dependent Variable
Expert Review/Heuristics Evaluation
- Should be conducted by more than one person - Should be an independent reviews - Not a member of the design team - Needs to be an Expert Review
Contants
- Things you want to keep the same - Same Time
Cognitive Walkthrough
- Usability inspection method used to identify usability issues in interactive systems, focusing on how easy it is for new users to accomplish tasks with the system. - Used in lieu of an expert review - Group effort - Can use existing staff
Style Guide Review
- Very low cost - Only minimal background needed - Good for addressing low level compliance, but not operational issues
Within Group
All of your data is in the same group. • Give Comparison Directly • Do not need as many people • Advantage, subjects are all the same, you have a twin. • Don't have to worry about the groups being different.
Co-Discovery
Ask two people to work on the product together.
Random Variable
Become Confounding Variables • Things you did control for.
Between
Between Group Design, has one of the independent variables. • Look at the difference between two groups. • Spend more time with each product • No influence between the products • Disadvantage, you need more people, twice as many. • Since you have the same amount, you don't get to spend as much time with the product.
Sampling (Recruiting) **
Connivence Sampling, Random Sampling.
Product Evaluation *
Design Making and Experimentation, NOT Market Research and Acceptance Testing.
Critical Instance Analysis.
Did not interrupt someone while they are doing a test.
Minimal Encouragement
Encourage a user to continue on with what they are saying with a nod or gesture.
Wizard of OZ Technique
Experiment in which subjects interact with a computer system that subjects believe to be autonomous, but which is actually being operated or partially operated by an unseen human being.
Interaction ***
Four Types: Low Fidelity/Low Functionality Mockup: Static WireFrame, Wizard of OZ. Low Fidelity/High Functionality Mockup: Interactive WireFrame. High Fidelity/High Functionality: Throwaway Mockup, True Prototype. High Fidelity/Low Functionality Mockup: Design Comp
GOMS Modeling
GOMS reduces a user's interaction with a computer to its elementary actions (these actions can be physical, cognitive or perceptual).
Connivence Sampling
Get people to sample your products from whomever is around you.
Open Ended Questions
Give them the responsibility to take over the conversation.
Story Board
Graphic organizers in the form of illustrations or images displayed in sequence for the purpose of pre-visualizing an interactive media sequence.
Random Sampling
Have a large group of people and randomly from those people.
Experimental Principles **
Independent Variable, Dependent Variable, Constants, and Random Variables.
Detailed Design **
Interaction and Information
Static Wireframe
Resembling a rough sketch or a quick mock-up, low-fidelity/static wireframes have less detail and are quick to produce.
Facilitation **
Open Ended Questions, Minimal Encourages, Reflections, Summarization.
Formats **
Performance Based Testing, Free Form/Exploratory Testing, Interrupted Task-based, and Co-Discovery
Design *
Preliminary/Conceptual Model and Detailed Design
Preliminary Design/Conceptual Design **
Story Board and Screen Flow Diagram
Non User Based Testing **
Style Guide Review, Expert Review/Heuristics Evaluation, Cognitive Walkthrough, and Predictive Models.
Dependent Variable
The variable that the experimenter hypothesizes is "affected by," or "related to," the independent variable. It is the "outcome" or "effect" variable.
Screen Flow Diagram
Type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows.
Prototype
Uses real code to create something people can interact and design with. Bad idea for design.
Protocols **
Within Group, Between Group, and Hybrid
Interrupted Instance Analysis
You did interrupt a person while they were doing testing.
Performance Based Testing
• Done on real products, need large groups. • Do it after you finish the product
Hybrid
• More than two. • Counter Balance the order to make it fair. If we feel that we have influenced the results.
