Transdermal Optical Imaging (TOI)
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.
Current Applications and Research in Transdermal Optical Imaging
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 situations.
