Blink Rate VR Calculator
Actual separately observed complete blink count/valid exposure seconds times60/minute, not automated blink event detector or dry-eye/fatigue clinical diagnosis.
Description
Blink rate counts complete observed blinks over a valid observation window.
Blink rate counts complete observed blinks over a valid observation window.1
It describes that exposure and does not by itself establish fatigue or an eye condition. The calculation and input requirements are explained below.
When to use Blink Rate VR Calculator
Enter an integer observed complete-blink count from 0 to 1000000 and positive valid exposure seconds.
How to use Blink Rate VR Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Blink Rate VR Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualIndependentlyObservedCompleteBlinkCount | Actual Independently Observed Complete Blink Count. Use the units and matching context stated in the calculation below. | number | Required; integer 0–1000000; finite; other constraints below |
| actualValidObservationSeconds | Actual Valid Observation Seconds. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Enter an integer observed complete-blink count from 0 to 1000000 and positive valid exposure seconds. Multiply the count by 60 and divide by seconds to return blinks per minute. It does not detect blink events from eye-tracking data.
blinksPerMinute=60*completeBlinkCount/observationSeconds Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Numeric result under the formula and output units explained above. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.

Use Pupil Diameter VR Calculator for a complementary operation: Pupil diameter varies with illumination and observation conditions.
Use Iris Illumination VR Calculator for a complementary operation: Iris illumination depends on spectral output, optical geometry and the measurement plane.
