A team of researchers at the University of Bradford in the UK has developed computer software that can detect fake and real smile difference. The study confirms that genuine smile secret lies in the eyes of a person. The study is published in the Advanced Engineering Informatics journal. 

Explaining about the software, the researchers say that movement near the eyes during a smile is detected by it. Dr. Hassan Ugel, University of Bedford, UK, the main researcher said that technology which is now able to recognize facial image was not able to recognize the real and fake smile of an individual. This new software will act as advanced technology and will spot false expression. It can help in improving the interaction between machines and humans in the future as well as aid mental health doctors in understanding their patients.

Working of the software

  • The new software will first map the face of the person in video recording and spot the mouth, cheeks, and eyes of the particular individual.
  • It then identifies the facial movements showing expression and smile.
  • The researcher used two different databases: real laughing phase and fake smiling face.
  • The number of movements or changes is measured during a smile and then detection showed the fake smile and real smile movements.

In this study, a big difference between changes in the mouth, cheek, and eyes with a fake and real smile is seen. The biggest difference was found around the eyes.

The software detected that in a real smile, muscles near the eyes shows 10 % more movement than a fake smile. 

Dr. Ugel explained that during a smile two types of muscle movement occurs:

  • Zygomaticus major which pulls the mouth upward 
  • Orbicularis oculus which makes the eyes smaller. 

During a fake smile, muscle of the mouth changes but doesn’t affect the size of the eyes much.
