Dr. Kang Lee and his postdoctoral fellow, Dr. Paul Zheng, developed
Transdermal Optical Imaging, the novel technology that uses facial
videos captured by conventional cameras and advanced machine learning
methodology to extract facial blood flow changes. This methodology was
initially used to help conduct lie detection studies with children more
naturalistically. Now, the technology has been implemented into a
smartphone application in collaboration with NuraLogix Corporation.
Using Transdermal Optical Imaging (TOI), blood flow information can be
extracted from the human face with only a conventional video recording.
Current research on Transdermal Optical Imaging is focused on testing
the applications of this contactless technology in measuring a person’s
psychological (e.g., stress, emotions, lies) and physiological (e.g.,
heart rate, breathing, blood pressure) changes in a variety of
