Google has added a new feature to Google Glass to allow users to take a pictures by winking that could be used to pay for products in the future.

The wink feature has been developed as part of Google’s attempt to help users “experience the world around you without getting bogged down by technology”.

Users previously had to use the camera by using a voice command or touching a button. Google believes the feature could evolve to be used for ecommerce.

Google said: “Imagine a day where you’re riding in the back of a cab and you just wink at the meter to pay. You wink at a pair of shoes in a shop window and your size is shipped to your door. You wink at a cookbook recipe and the instructions appear right in front of you – hands-free, no mess, no fuss.” 

The technology giant has also unveiled further features to its Google Glass wearable technology such as the ability to upload videos straight to YouTube by swiping the device or by voice commands.
