This Performance Assessment Study will focus on testing the performance of the VitalSigns Camera under various suboptimal use cases. The software makes it possible to measure the pulse rate (PR) and respiration rate (RR) without the device being in contact with the subject. The software delivers fast and accurate results (in less than one minute). Vital signs camera (VSC) product will be used via a demonstrator app on one of the smartphones during the study sessions (camera of the phone will be used by the VSC product). Devices will be provided by the researchers.

The subject will be asked to perform a number of assignments with the software application. The study involves taking a number of measurements of the subject's PR using the VitalSigns Camera software application (which is installed on a smartphone or laptop). In this study only PR is measured and not RR as the latter parameter is not affected by the designed test cases. The total duration of the session will be approximately 1 hour. In total, approximately 30 healthy volunteers will participate in this study.
