    Health and emotions monitoring

As we experience physiological and emotional changes, our blood flow changes, too. It is a natural bodily reaction that can sometimes be quite obvious. For example, we often attribute rosy cheeks to embarrassment or anger. Most times, however, those changes are so subtle the human eye can’t even notice them. Well, NuraLogix is about to change that.

About NuraLogix

NuraLogix combines neuroscience, psychology, physiology and deep learning to detect, measure and analyze human affects. The company developed a technique called Transdermal Optical Imaging™ (TOI™) which extracts facial blood flow information from the human face using any video camera, including those found in a smartphone, laptop or tablet. 

Being able to visualize blood flow changes in different facial areas helps reveal useful information about the person’s health and emotional state. For example, it can be used to measure blood pressure, heart rate, current emotions, and more. As it is with everything related to healthcare, precision and accuracy are top priority.

Achieving accuracy with FaceTrack

The first step in detecting facial blood flow is to detect the face. To do that, NuraLogix used FaceTrack.

FaceTrack tracks 99 facial points in real time, which makes it easy to detect specific areas of interest. Since it’s very lightweight, it can run smoothly on any platform and device, delivering great results with all types of digital cameras.

With reliable face tracking as the basis, TOI™ can easily collect blood flow information from relevant facial areas. Since human skin is translucent, the light that reaches the face is reflected in different layers below the skin. TOI™ extracts this information from conventional video images. The results are then processed and sent back to the user’s device for display and further analysis.

Innovation in health monitoring

NuraLogix solutions allow doctors to monitor patients’ health remotely, using just a simple webcam. There is no need for additional equipment since the software gathers all relevant information straight from the camera. It’s a simple and non-invasive method of measuring blood pressure, heart rate, stress levels, and more, helping create a picture of the patient’s health condition. This reduces the costs for hospitals, but also saves patients’ time.

The technology can also be used to measure emotions. Although people can fake their emotions (or lack thereof) on the outside, they cannot control their autonomous nerve system that controls the blood flow. Distinguishing between specific blood flow changes on people’s faces allows the software to reliably estimate people’s emotional states.
