Practical Cases During Baseline Creation

Examples showing how worker technique impacts the time required to build the reference profile.

Baseline creation in Optovera requires at least 10 successful measurements that form each worker’s pupillary profile. This profile serves as the reference for all future tests.

At this stage, the worker’s technique not only ensures each test’s validity but also determines the total time required to complete the baseline. A technical error may result in repeated tests and delay the process.

Case 1: 10 initial tests with proper technique ✅

  • Situation: The worker follows all instructions: visor properly positioned, eyes wide open, fixed gaze without blinking.

  • Impact on time:

    • All 10 tests are completed in the shortest time (typically 5–7 days, respecting the 2-valid-tests-per-day rule).

    • Baseline is created with no delays.

  • Lesson: Proper technique from the start allows for quick and efficient enrollment.

Case 2: Type 2 Error on the fourth test ⚠️

  • Situation: The worker completes 3 successful tests, but in the fourth, fails to open their eyes enough → Type 2 Error.

  • Impact on time:

    • The initial authentication sequence is broken.

    • The worker must restart the series of 4 consecutive successful tests.

    • This adds several days to the baseline creation.

  • Lesson: A single error in this initial phase resets the process and prolongs baseline setup time.

Case 3: Type 2 Error on the 5th and 10th test ❌

  • Situation: The worker completes 4 consecutive successful tests and is authenticated but makes mistakes on the 5th and 10th tests (eyes not open enough).

  • Impact on time:

    • Authentication remains valid.

    • Errors prevent reaching 10 successful tests.

    • Extra days are needed to collect valid tests and finish the baseline.

  • Lesson: Errors after authentication don’t reset progress but still extend the time needed to finalize the baseline.

Conclusion

Baseline construction depends not only on the technology but also on the worker’s technique. Good execution allows quick baseline completion, while poor technique delays the process. For HSE, initial training and active supervision are critical to avoid delays and ensure operational continuity.
