Normalized Stress Index

The Normalized Stress Index value is sent as part of the final results.

The application can receive the Normalized Stress Index result by implementing VitalSignsListener:

Kotlin

override fun onFinalResults(results: VitalSignsResults) {
    runOnUiThread {
        (results.getResult(VitalSignTypes.NORMALIZED_STRESS_INDEX) as? VitalSignNormalizedStressIndex)?.let { normalizedStressIndex ->
            Log.i("VITAL SIGN", "Normalized Stress Index: ${normalizedStressIndex.value}")
        }
    }
}

Java

@Override
public void onFinalResults(final VitalSignsResults results) {
    runOnUiThread(() -> {
        VitalSignNormalizedStressIndex normalizedStressIndex = (VitalSignNormalizedStressIndex) results.getResult(VitalSignTypes.NORMALIZED_STRESS_INDEX);
        if (normalizedStressIndex != null) {
            Log.i("VITAL SIGN", "Normalized Stress Index: " + normalizedStressIndex.getValue());
        }
    });
}

For general information about vital signs see the Vital Signs and Health Indicators Information Document.

For a list of supported vital signs by platform and measurement mode (face/polar), along with their required measurement durations, refer to the Indicators Technical Information page.

Important

Note that vital signs are sent on a background thread. The application must switch to the UI thread in order to perform UI updates.
