9 Physical Activity Monitoring for Heart Rate 1 Scope This standard creates definitions and performance criteria for consumer technology that measures heart rate (HR). 2 Introduction The following assumptions are provided to users of this standard. 2.1 Stakeholders Wearable device companies who want to understand what guidelines need to be adhered to in order to meet a basic standard for HR monitoring accuracy. Wearable device companies who want to make sure that consumers or media who test their device for HR accuracy have a clear standard to test against so outcomes can be reported accurately. Consumers who want to know if a specific device meets the minimum standards for HR accuracy. Media who want to test the accuracy of a HR monitor for a specific device. Researchers who want to know if a specific device meets the minimum standards for HR accuracy. Organizations trying to make decisions on which devices to recommend to employees and patients. 2.2 Purpose Provide organizations who want to test continuous measurement HR monitoring devices with a standard process that ensures the device meets the basic standard for HR accuracy as defined by the CTA. Provide a standard protocol to test and validate the accuracy of a HR monitoring device under the conditions of everyday living. 2.3 Other Considerations This standard was produced to examine performance of devices that measure continuous HR. Participant characteristics, test conditions, and protocols were chosen to include a range of conditions that allow for examination of HR from devices utilizing varying techniques. It is acknowledged that current and future methods for monitoring HR may benefit from additional analysis beyond that recommended in this document. For example, optical techniques may be affected by ambient light, electrical techniques may be affected by external electronic sources, and audio techniques may be affected by ambient noise. Additionally, sensor location on the body may be more or less suited for particular protocols. With that in mind the following considerations are noted as potentially important while not accounted for in the current standard. Participant characteristics: specific age ranges, hair density, body composition. Test conditions: variable ambient light (e.g.,, direct, indirect, and sun/shadow transitions), wide ranging temperatures (cold and warm), wide range of ambient noises, incorporation of clothing that may have the potential to interfere with devices (e.g., tightness, thickness, or that which 1
