手机惊现测谎app

    A technology company is developing a lie detector app for smartphones that could be used by parents, teachers and lovers.

    The app measures blood flow in the face to assess whether or not you are telling the truth.

    Parents could use it on their children to see if they are lying and teachers could work out which of their pupils are truthful.

    The app is being developed by Toronto startup* NuraLogix and the software is called Transdermal Optical Imaging.

    The idea is that different human emotions create different facial blood flow patterns that we have no control over.

    These patterns change if we are telling the truth or telling a lie.

    Using footage from the smartphone camera, the software will see the changes in skin color and compare them to standardized results.

    A study from last year found that anger was associated with more blood flow and redness whilst sadness was associated with less of both.

    Developmental neuroscientist* Kang Lee, who has been researching the field for 20 years, said the technology would not replace lie detectors used in a court of law.(SD-Agencies)
