Clearly we get asked a lot of questions about our technology and how it works. We’ve tried to answer the most commonly asked questions here, but if you have a specific question or a support query, please fill in the form below.
PPG also known as Photoplethysmography is an optical non-invasive method for measuring the blood volume changes per pulse. It effectively represents the mechanical activity of the heart.
RPPG or remote Photoplethysmography is a method by which a face reader can measure heart rate and heart rate variability remotely. Where PPG is mostly used with wearable devices, RPPG detects the heart rate by using light and a completely contactless method. It measures the variance of red, green, and blue light reflection changes from the skin, as the contrast between specular reflection and diffused reflection.
No, our algorithms adjust for makeup on the face.
We’ve done many tests with a number of different skin tones.
We are not a device, we offer a software based solution which offers a first line of defence to detect vitals based on rPPG technology. This technology does not replace a physical device which would be used in a hospital or by a medical professional.
Our accuracy is currently 95% against a regulated device. We performed many tests with large data sets to help our technology increase accuracy over time.
Yes, it works on any iPhone 5 and above. It also works on most Android devices with a hi-res camera.
Yes, there is an iPad version also available.
We now have a web based solution that works on any device that has an embedded camera and a web browser.
As often as you like, we would recommend once a day, but depends on what you want to assess. The more vitals we can accumulate, the more predictions we can make.
We’ve tested our technology on a variety of ethnicities including darker skins and we believe our technology works extremely well across different skin tones.
No, our solution needs an internet connection as all the ‘heavy work’ of processing is done in our cloud servers from anywhere in the world. We need a decent 4G or good WiFi connection in order to get good accuracy.
No, we only sell our SDK (software development kit) delivered to enterprises for health & wellness purposes, who typically integrate our SDK into their application to gather vital signs data as part of their overall offering. You cannot download our app from Google Play store or the App Store.
Please provide your contact information and details of the issue so that we can raise a support ticket.
