Recent research on emotion detection based on facial expressions , highlights that mere expressions are not sufficient to detect emotions. A smile does not necessarily indicate happiness and a scowl does not always imply anger. Realistically, there are different ways of expressing anger and smiles could also mean embarassment.The current technology in medical settings, national security, market research use only a one-to- one expression to emotion match. This method does not entirely reveal the actual truth says the study. A more comprehensive model that encompasses all the complex aspects of human emotions is required. Voice modulation, changes in gait, head movements and other indicators are important to be considered as well. The researchers are convinced that this would be a more accurate way of detecting emotions.
