FUURAA thesis
An interface fails when people cannot predict or control the encounter.
Engineering map
Turn the title into engineering objects that can be observed, measured and reviewed.
Each layer states the boundary to establish and the evidence needed for the next decision.
Access
Design controls for diverse reach, vision, hearing and language.
Truth
Disclose remote help, recording and actual limitations.
Verification questions
Write the questions first, then decide whether a demo, test, pilot or operating record can answer them.
Each question needs an object, conditions, denominator, threshold and accountable decision owner.
- 01
Can first-time users predict motion?
- 02
Can varied users stop or get help?
- 03
Is remote presence visible?
- 04
What if speech interaction fails?
Evidence to preserve
Enable the next reader to reconstruct conditions, results, failures and the decision.
A conclusion alone loses reviewability; raw records, configuration and exclusions matter too.

Misunderstanding and help log
Scope boundary
State what this evidence still cannot be generalised to.
- 01
A face, speech or high satisfaction score does not prove comprehension or consent.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
