Consumers can experiment with different looks in the apps that act like augmented reality mirrors. With the Beauty Mirror app, which uses filters, people can see how they would look with fewer wrinkles, bigger lips or lifted eyebrows in a real-time photograph or video. “Our idea was to apply a subtle, realistic change to a person’s reflection so that when someone put it on Facebook no one would know it was an altered video,” said Parham Aarabi, the CEO of Toronto-based ModiFace, which created the app. The ability to change 2-D photos before uploading them to Facebook has been really popular, but now people can take video and touch it up using the app too,” he said.
