The emotion-detecting tech works with any camera, including the one on your smartphone
In the future, your smartphone might be all you need to snare a liar.
Canadian start-up NuraLogix has developed an imaging technology that it claims can pick up on hidden emotions and determine whether or not a person is being truthful.
NuraLogix's Transdermal Optical Imaging software works by monitoring blood flow changes in the face.
These changes are said to occur automatically when humans experience different emotions, forming part of the body's natural fight or flight response.
Specifically, NuraLogix's image processing technology tracks the concentration of haemoglobin in different parts of the face, such as eyelids, cheeks and forehead.
