We  developed a technique called Transdermal Optical Imaging (TOI™) which utilizes a conventional video camera to extract facial blood flow information from the human face.  Applying advanced machine learning algorithms, physiology and neuroscience we’re able to use this information to model and detect a wide variety of human physiological and psychological affects.

The basic principle works like this:

Facial skin is translucent. Light and its respective wavelengths reflect off different layers below the skin which contains blood vessels and melanin. Changes in blood flow can be captured using a conventional video camera such as that found in a smartphone, laptop or tablet.

TOI™ uses face tracking technology to identify and track faces in a video stream.  Blood flow data is  then extracted using machine learning based bit-plane image analysis.  Deep Learning based models are then applied to predict physiological and psychological affects.

What we can measure/predict:

Physiological: heart rate, blood pressure, respiration rate, cardio stress...more

Psychological: mental stress, emotional valence, individual emotions (joy, sad, fear, disgust, surprise, tranquil, bored, neutral...more)
