How anxious are Croatians?20% of population deal with strong or extremely strong anxiety.Increased levels of anxiety contribute to the development of mental health issues and chronic illnesses, and consequently, lead to a shorter life span, which for Croats is already shorter than the European average.We used cameras in existing digital DOOH locations and paired them with innovative use of AI-based mood recognition algorithms that were able to perform facial coding and measure anxiety levels of passers-by.The execution was intuitive and simple, as passers-by would walk past, the screen invited them to participate. The users would stand in front of the screen, give their consent by waiting 5 seconds for the application to screen their face and show them their level of concern, which would be automatically measured and displayed.Instead of people watching commercials, commercials now watched them back, for a greater good – their mental health.
