D800 is a core course in WGU's M.S. Computer Science, Human-Computer Interaction specialization.
WGU describes it as covering HCI principles drawn from psychology, design and engineering, preparing students to design and evaluate user-centered systems with tools such as wireframing and eye tracking, and to analyze user testing results. It also includes completing CITI Institutional Review Board training for working with human subjects.
The course mixes design, research method and ethics. Many students are comfortable with one of the three and need to build the others. The guide lists four competency units.

What D800 Covers
| Competency (summarized) | What it means in practice |
|---|---|
| Analyze how humans interact with computing devices | Use cognitive and perceptual principles to explain behavior |
| Create intuitive, accessible, engaging systems | Apply user-centered design techniques such as wireframes |
| Design a user testing plan | Define tasks, participants, measures and procedure |
| Analyze user data and feedback | Interpret results to improve usability and effectiveness |
Key Concepts Explained
Usability Principles
Heuristics such as visibility of system status, consistency, error prevention and recognition over recall give a shared language for reviewing a design. Accessibility adds needs of users with different abilities.
Example: A form that clears all entries after one error violates error recovery. Keeping valid entries and highlighting only the problem field supports users and reduces frustration.
Designing a User Test
A test plan states the question, participants, tasks, measures (success, time, errors, satisfaction), setup and how data will be analyzed. Tasks should be realistic and avoid leading wording.
Example: Instead of "Click the blue Pay button", a task says "Pay for the items in your basket". Observers note whether the participant finds the control without help.
Ethics and Consent
Research with people requires informed consent, privacy protection and the right to withdraw. IRB review checks risks and safeguards. The course includes CITI training so you understand these duties.
Typical Assignments and How to Approach Them
| Task element | What it tests | How to approach it |
|---|---|---|
| Interaction analysis | Principles | Link observed behavior to a named principle |
| Wireframes or prototype | User-centered design | Annotate decisions for accessibility and clarity |
| Test plan | Research design | Define tasks and measures that answer the research question |
| Results analysis | Interpreting data | Summarize with simple statistics and explain what to change |
Linking Measures to Questions
A test plan is weak when measures do not answer its question. Use a short grid to check the link before you write.
| Research question | Task | Measure |
|---|---|---|
| Can users complete checkout? | Buy an item | Completion rate, errors |
| Is the flow efficient? | Same task | Time on task |
| Is it satisfying? | After the task | Short rating scale and comments |
Readiness Checklist Before You Submit
Check design, method and ethics together.
| Check | What to confirm |
|---|---|
| Principles named | Observations are tied to usability principles |
| Accessibility considered | Design notes address varied abilities |
| Plan complete | Question, participants, tasks, measures and procedure |
| Consent covered | Consent, privacy and withdrawal are described |
| Analysis leads to action | Findings produce specific design changes |
Splitting Your Study Time
Plan the ethics training early, since it must be completed and can hold up the assessment if left late. Then give the largest share of time to the test plan, which is where design, method and ethics come together.
| Stage | Focus |
|---|---|
| CITI training | Complete the module and note the key consent principles |
| HCI principles | Learn heuristics and cognitive foundations |
| Wireframes | Draft and annotate for accessibility |
| Test plan | Question, tasks, measures, procedure |
| Analysis practice | Summarize sample data and propose changes |
Where Students Get Stuck
- Treating ethics as paperwork. The CITI training and consent reasoning are part of the course.
- Leading tasks. Neutral wording is needed for valid results.
- Overclaiming from few participants. Describe limits honestly.
- No design response. Analysis should end with changes to the design.
Study Tips for D800
- Learn the usability heuristics and an example violation for each.
- Pilot your test on one person before writing it up.
- Keep raw observations separate from interpretation.
- Complete the CITI module early so it does not delay the assessment.
How We Help with D800
Send the task, rubric and any draft. A writer with UX research experience can prepare a worked model for study, explain test design and basic analysis, or review your plan for leading tasks and missing consent steps. See our master's assignment help guide for how orders work.
GradeEssays is independent of Western Governors University. Model work is for study and reference; what you submit must be your own under WGU's academic integrity policy, and no outcome is promised.
We never complete training modules or certifications for students. Orders are written from scratch with free revisions within the scope of your original request, and a full refund if late.
