List the principle families you remember. Add one accurate example of each.
Task 10: Studied-Interface Evidence Organiser
Level 1 HCI external · choose · observe · verify · explain · recall
1. Closed-book retrieval — six minutes
Keep notes and devices closed. Rebuild what you already know before using the organiser.
Rebuild the steps from an observable feature to an effect on interface purpose.
Explain why a caption button, Back button or colour setting is not automatically a usability principle.
What is the difference between something observed, documented and assumed?
2. Interface selection gate
The 2026 specification requires candidates to study an interface of their own choice before the assessment. Test the scope you will actually study—not an entire product ecosystem.
Several states, screens or decisions affect a task—not a single passive screen.
I can revisit and safely repeat actions without relying only on memory.
I can name what success means and who is trying to achieve it.
I can observe two complete actions from start state to outcome.
I can investigate effective choices and friction rather than defend a favourite.
Several lenses can be tested, without forcing every family onto the interface.
I will not expose private data, spend money, publish content or affect another person.
I will use Mātāpono Māori only where language, tikanga, mātauranga or another relevant Māori relationship is genuinely evidenced.
Task flow 1:
Task flow 2:
Back-up interface if access fails:
Kaiako approval:
3. Observation protocol
Name purpose, user and task.
Complete once, reset, then repeat slowly.
Write what appeared or happened.
Vary one condition safely.
Observed, documented or assumed?
Link mechanism to user and purpose.
Keep the task or outcome alike.
Answer an evidenced limitation.
4. Evidence bank — what happened?
Complete six evidence rows across at least two task flows. Describe first; label second.
| # | Observable feature | User/task | Principle |
|---|---|---|---|
| 1 | |||
| 2 | |||
| 3 | |||
| 4 | |||
| 5 | |||
| 6 |
Evidence and status
| # | Evidence | Evidence status: observed/documented/assumed |
|---|---|---|
| 1 | ||
| 2 | ||
| 3 | ||
| 4 | ||
| 5 | ||
| 6 |
5. Evidence bank — why does it matter?
Use the same row numbers. Reach the purpose, test your claim, then propose a change grounded in evidence.
| # | Effect on usability | Effect on purpose | Counterargument/limitation |
|---|---|---|---|
| 1 | |||
| 2 | |||
| 3 | |||
| 4 | |||
| 5 | |||
| 6 |
Comparison and improvement
| # | Comparison | Improvement |

6. Peer evidence audit
I can point to what happened; labels such as “easy” or “inclusive” are explained.
The effect belongs to a named person doing a named action.
Observed, documented and assumed claims are not blurred together.
The explanation shows why the feature matters to what the interface is for.
The same action, user need or outcome is being compared.
The change answers a demonstrated limitation and notes a trade-off.
The chosen lens explains the evidence better than a plausible alternative.
A Māori concept is used only when the relevant Māori context or relationship is evidenced.
One status I changed after the audit, and why:
One evidence record I strengthened:
7. Two response plans
Build two different arguments. Use row numbers so you can see which evidence will do each job.
Focus or judgement:
Evidence row numbers and principle:
Mechanism → user/task → purpose:
Comparison, limitation or trade-off:
Improvement and why it is suitable:

8. Close the organiser: recall check
Turn this page over or close the tab. Tell a partner your three strongest examples from memory. For each one, include the feature, user/task, principle, effect on usability and effect on purpose. Add one limitation. Reopen the organiser only to check what you missed.
