Clinical Measurement Reports

Clinical trials are conducted to validate the accuracy of each parameter. The measurement details and results are presented under each subpage.

Moment-to-moment fluctuations in the user's physiology mean that risk estimates could vary to some degree from one measurement to the next. The best estimate of a user's overall risk can therefore be obtained by averaging several measurements throughout the day and across several days to adequately account for this physiological variation.

Each measurement is conducted with the following minimum information requirement, data collection setup, and data collection procedure (additional details are provided if any):

Information Required

• Blood flow information extracted from video of the user’s face (BitDoctor Technology)

• Demographic information (From the user profile)

Data Collection Setup

The participant’s face was illuminated with LED lights. Blood flow information was captured from conventional video of the face using BitDoctor Application for iOS (research version).

Data Collection Procedure

BitDoctor Application was activated to record a 30-second video of the subject using the front facing camera of the iPhone. At the end of each recording, subjects were asked to fill out a questionnaire to collect their demographic information.
