Design exercise: Human-Computer Interaction
Human perception, cognition, motor control, interaction techniques, accessibility, evaluation, and responsible design. Implement designOutline() returning non-empty values for: userContext, interactionTechnique, evaluation. Each value must name a concrete mechanism or decision.
The mechanism
HCI treats system quality as human task performance and experience. Design from users and context, prototype interactions, and measure effectiveness, efficiency, errors, and trust.
Expected evidence
A design outline with userContext, interactionTechnique, evaluation plus an explicit failure mode or trade-off.

Hints when you need them
- Name the failure mode before selecting the mechanism.
