Evexia uses the latest technology for optimal performance and capabilities.  Users can measure vital signs in a matter of seconds, at any time and from any location using their smartphone, iPad, laptop, or desktop.

Evexia uses rPPG technology for contactless measurements via the front-facing camera of smartphones, laptops or desktops and PPG for contact-based measurements via smartphone rear cameras.  No additional gadgets are needed.

Evexia does not save images or input video streams used for measurement.  Measurement results are saved for historical purposes and user convenience. 

All results are secured, encrypted and accessible only by the end users and account admins who have access permissions.  This is set up in account preferences.

Users can view and download personal trends, historical data and health indicators from the user portal within the application.

Evexia has user access controls and only users with the right access profiles can access data.  Purchasing organisations define the access controls required by their end-users (patients, medica, admin and management teams).

Contactless Video-based Monitoring

For contactless data extraction, Evexia uses rPPG (remote photoplethysmographic imaging).  rPPG is a camera-based solution for contactless cardiovascular monitoring, proven to be as accurate as traditional PPG devices. 

Contact-based Monitoring

MIT Media Lab's Joy Buolamwini and Timnit Gebru from Stanford's research study (2018) demonstrated how three commercially released facial-analysis programs from major technology companies demonstrate both skin-type and gender biases.  The conclusion supported by other researcher is that potentially, such applications are detremental and have consequences for those who fall under these categories.

Evexia has another approach for extracting measurements to cater for difficult scenarios.  Evexia uses a contact-based solution which extracts a PPG signal when the user places their finger on the rear camera of a smartphone.  
Evexia automatically detects when conditions are not ideal for contactless rPPG extraction and suggests using the contact-based extraction.

Monitoring Mental Stress

Evexia uses the Baevsky Stress Index and heart rate variability (SDNN and/or RRi raw data) measurements to calculate users’ stress levels and provides easy-to-read stress results on a 5 point scale: low, normal, mild, high, and extremely high.  Our development partners are seasoned experts in the field of technology and AI.  The features and functionality continuousley undergo various phases of testing, both in-house and externally at academic institutions (as part of clinical studies) and at medical labs.

Extracting Measurements

Health measurements are extracted from a video stream of exposed skin on the surface of a human face.  The video stream is analysed with advanced AI and deep learning algorithms, including computer vision technology and signal processing. No identifiable features or demographic data (e.g., eyes, height, gender, weight, etc.) are needed.  In approximately one minute, users can measure blood pressure, heart rate, heart rate variability (SDNN and/or RRi raw data), oxygen saturation, respiration rate, sympathetic stress, parasympathetic activity and pulse-respiration quotient.

Evexia runs on the user's device, enabling them to perform scans without connection to the internet.  When offline, results will not be recorded in measurement history.
