Though we know bad things happen in this world, sometimes its hard to see how we can make a difference. UK charity Women’s Aid is using clever billboard technology to generate action against domestic violence through its interactive campaign, ‘Look at me’. The billboards feature the image of a woman’s bruised face which ‘heals’ as more people take the time to look at her. Facial recognition technology helps to make the point: if we can see it, we can change it. Outside the non-profit sector, facial recognition tech has been used to tailor advertising screens based on shoppers’ gender and age, but is still a controversial marketing tool due to privacy concerns.
