Three Reasons Why You Were Wrong About Camera-based Health Checking Accuracy
We outline three popular views on remote health-checking accuracy we believe are outdated.
Camera-based health-checking methods are attracting expanded interest in the tech and healthcare markets.
In preparation for certification of Shen AI as a medical device, we conducted preclinical validation studies that at the same time disprove the most popular myths about the accuracy of camera-based health monitoring.
We outline three popular views on remote health-checking accuracy we believe are outdated.
1. To make an accurate measurement you need a specialized device: mistake.
This is a popular opinion, although it turns out not to be true. Preclinical validation study of Shen.AI Vital was conducted by researchers from the Wroclaw Medical University, the leading University in Poland in the clinical and health subject.
The study concerned precision and accuracy of heart rate, heart rate variability and breathing rate measurements using Shen AI Vitals technology. During this study, scientists used the average smartphone. This is significant information in the context of subsequent availability for standard users.
Smartphone, tablet, laptop ā these devices are enough to perform an accurate measurement of vital functions using Shen AI technology.
2. The remote health checking study is conducted only internally: sometimes, but not in this case.
Analyzing such studies, you should look at the research methodology and the unit that conducts it.
Wroclaw Medical University cooperates with Shen AI in researching Shen AI technology. For this purpose, Shen AI provides the necessary information and provides technological solutions to perform measurements. However, Shen AI does not influence the analysis of this data and its subsequent interpretation in any way. All tests carried out are fully independent, and the interpretation of the results is solely the responsibility of scientists at the Medical University of Wroclaw.
3. Camera-based health checking is less accurate than smartwatches: mistake. Itās comparable.
Shen.AI Vital currently measures heart rate, heart rate variability and breathing rate, similar to smartwatches. The technology created by the MX Labs team is being developed to measure further vital parameters, such as blood pressure and stress index in the future. The premiere of new features will take place in 2023. We already know that in terms of the range of measurements, Shen.AI will have a wider range than regular smartwatches.
But how does Shen.AI Vital accuracy compare to smartwatches?
When comparing accuracy data for Shen.AI and smartwatches, we took into account the main metric ā heart rate due to available research reports.
According to the study on smartwatches, the accuracy of measuring heart rate is similar to Shen AI Vital technology. The accuracy of measuring the heart rate by the smartwatch varies depending on the model 100% ā 94% (during standard measurement). The Apple Watch showed the highest accuracy and Galaxy was comparable. Shen AI showed 99.5% accuracy when measuring standard heart rate.
In summary, a camera-based health-checking method like Shen AI Vital is just as accurate as a smartwatch worn directly on the skin. It shows how much potential contactless methods have in the development of healthcare.
Are you inquisitive? Do you put the measurement accuracy of new technologies in the first place? We are the same.
