7 tech innovations of 2016

LOS ANGELES -- There was lots of talk about virtual reality in 2016, but most of it was looking forward to trends that might come true in a few years. The real action, however, was in another form of reality, the augmented kind. AR, or augmented reality, tops our annual list of tech innovations for 2016, highlighted, of course, by the Pokémon Go app, and all those crazy filters we added to our Snapchat photos. Snapchat, the app originally beloved for sending photos that could disappear within 10 seconds, has expanded into a service some 150 million visit daily, fueled by the selfie lens, where you can add cat ears and rainbow tongues to your photos and videos. In November, it went one step further with the introduction of "World Lenses," which put smiles onto ordinary clouds in the background of your photo, or add falling rain or snow to an image.
