In a brilliant article at MIT Technology Review, Tate Ryan-Mosley gives an overview of the history and challenges of face and beauty filters that are popular on social media apps and platforms:
The face filters that have become commonplace across social media are perhaps the most widespread use of augmented reality. Researchers don’t yet understand the impact that sustained use of augmented reality may have, but they do know there are real risks—and with face filters, young girls are the ones taking that risk. They are subjects in an experiment that will show how the technology changes the way we form our identities, represent ourselves, and relate to others. And it’s all happening without much oversight.
He also mentions an interesting bit of history of face filter technology that originated in Japan:
These real-time video filters are a recent advance, but beauty filters more broadly are an extension of the decades-old selfie phenomenon. The movement is rooted in Japanese “kawaii” culture, which obsesses over (typically girly) cuteness, and it developed when purikura—photo booths that allowed customers to decorate self-portraits—became staples in Japanese video arcades in the mid-1990s. In May of 1999, Japanese electronics manufacturer Kyocera released the first mobile phone with a front-facing camera, and selfies started to break out to the mainstream.
