Subject Demographic Information ​

In order to provide highly accurate results, the SDK requires demographic information regarding the user who is taking the measurement. This information is not mandatory, but it improves the accuracy of the vital signs that are calculated by the system. The demographic information consists of three fields:

• Sex (as classified at birth) [UNSPECIFIED / MALE / FEMALE]
• Age [years]
• Weight [Kilograms]

The application can provide the demographic information as part of the session initiation.

In the following example, the sex is female, the age is 35 years and the weight is 65 kilograms. In the example the measurement session is a face session, but it can be used in a PPG Device session as well.

try {
    val licenseDetails = LicenseDetails("<ENTER_YOUR_LICENSE_KEY>")
    val subjectDemographic = SubjectDemographic(Sex.FEMALE, 35, 65) 
    val session = FaceSessionBuilder(applicationContext) 
                    .withSubjectDemographic(subjectDemographic) 
                    .withImageListener(this)
                    .withVitalSignsListener(this)
                    .withSessionInfoListener(this)
                    .build(licenseDetails);
} catch (e: HealthMonitorException) {
    Log.i("ERROR", "Received Error. Domain: ${e.domain} Code: ${e.errorCode}")
}

try {
    LicenseDetails licenseDetails = new LicenseDetails("<ENTER_YOUR_LICENSE_KEY>");
    SubjectDemographic subjectDemographic = new SubjectDemographic(Sex.FEMALE, 35.0, 65.0); 
    Session session = new FaceSessionBuilder(getApplicationContext())  
            .withSubjectDemographic(subjectDemographic) 
            .withImageListener(this)
            .withVitalSignsListener(this)
            .withSessionInfoListener(this)
            .build(licenseDetails);
} catch (HealthMonitorException e) {
    Log.i("ERROR", "Received Error. Domain: "+ e.getDomain() +" Code: "+ e.getErrorCode());
}

If any of the demographic parameters is unknown, it is recommended to provide the known parameters and to leave the others null/UNSPECIFIED.
