CES 2023: Video Selfie Measures Vital Signs

We recently covered NuraLogix’s Anura, a video-based blood pressure tech app that is now a shipping product in the iOS and Android app stores. Another similar but more advanced tech is Caducy, which is also a CES 2023 Innovation Awards Honoree. It uses AI and deep learning techniques to analyze physiological parameters including heart rate, respiratory rate, and blood pressure using a quick 30-second video selfie. It can also measure stress level and heart rate variability with 95% accuracy. Unlike Anura, this tech is intended for healthcare professionals through telemedicine platforms. The main objective of the medical device is to satisfy the growing need for enhanced remote patient monitoring functionalities.

The technology analyzes health signs from the skin on the face. Since blood can be seen flowing through the skin, the pulse rate is determined by a signal analysis performed directly on the subject’s face, and the respiration rate is estimated by simply looking at the subject’s chest. Remote photoplethysmography (rPPG) signal processing and AI enable the observation and recording of periodic waves analogous to the pulse wave on the surface of a human face through a video feed.

This product has passed two clinical investigations involving more than 1,000 participants and is ISO 13485:2016 certified. This application is GDPR compliant, guarantees online safety, and does not retain personal information. In addition, this program is compatible with practically all multimedia devices, such as computers, tablets, and smartphones. On a basic web page, it is also accessible via SaaS and API. According to i-Virtual, they are working on acquiring CE approval shortly, and the FDA clearance procedure is also underway.
