One of the newest “smart” devices is an old favorite, a camera. And smart cameras are getting smarter all the time. Some are now built with machine learning tools to help them think for themselves. Machine learning involves patting large amount of data into a computer for processing.

Google Clips

One of the latest to launch is Google Clips. It is the first camera developed by the web search giant that is not built into a phone.

The small and light device is designed to be put somewhere in a room to take pictures by itself. It can also be stuck to an object or a person’s clothing.

Google says machine learning helps the camera choose the best times and situations for taking pictures and video clips. It can also recognize the faces of people or pets chosen by the user and take pictures of them in a more natural way.

The device is not yet being sold, but interested buyers can join a waiting list to be informed when it is available.

GoPro Hero

GoPro is another company developing machine learning technology. GoPro also uses machine learning to power its QuikStories feature. This tool takes existing photos and videos and automatically creates a finished video piece, complete with music and effects.

Snap Spectacles

Messaging app Snapchat sells a pair of sunglasses with a built-in camera that can record short video clips with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “capture the moment, without taking you out of it.” Many smart phones already have facial recognition technology built into the devices.

Snap Inc. has started selling its Spectacles sunglasses online in the United States.

Apple iPhone X

Apple’s new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous devices that used a fingerprint to unlock the phone.

Apple says the system works by projecting more than 30,000 dots on the face to create a kind of map. Apple claims its facial recognition is even secure enough to allow payments through its Apple Pay service.
