Decision 01
Prepare people for the physical task.
The scan explains movement, framing, and environmental requirements before capture begins.
AI-Guided Environment Validation·Computer vision · bounded human-AI recovery
First-attempt failures showed that recovery needed as much design attention as scanning.
I designed and tested a guided mobile scan that could detect room issues, explain what needed correction, bound repeated failure, and guarantee a route to a human greeter.

// Three product decisionsInterface first
Three decisions shaped scanning and recovery.
Replace four static room photos with guided video and issue detection without allowing persistent AI uncertainty to block an exam.
Decision 02
Give guidance while the candidate can still correct course.
In-scan feedback makes framing and coverage visible instead of waiting until the end to announce failure.
Decision 03
Bound retry and preserve a human exit.
Specific issue results support self-correction.

Evidence and outcome
Participants struggled most with the scanner.
Six participants rated issue results 4.1/5 and the overall proof of concept 3.8/5, but the scanner itself scored 3.4/5. None succeeded on the first scan, and participants restarted one to four times.
// ReflectionLimits and next questions
The proof of concept exposed what still needed work.
Tradeoff
More retries may improve capture quality but increase anxiety and time.
Evidence boundary
The 70% detection and 20% false-positive figures are experiment targets, not achieved production results.
Next test
Retest the scanner guidance and retry threshold before making a production efficiency claim.
