'Look ma, no hands': Swedish start-up launches touchless selfie app

Selfie fans, your life just got a little easier. A Swedish tech start-up has launched an app for Apple devices that lets people take photos of themselves without having to touch their screens. Using touchless technology which it says is ideal for taking "selfies" or "groupies", Crunchfish's GoCam app lets users trigger photos or videos from a distance with just hand gestures.
Photos can be triggered from a distance of up to 3 m (yards), it says.
The company, based in the southern Swedish city of Malmo, says the free GoCam app will be initially available in Sweden and Australia.
While gesture recognition has become more popular thanks to products such as Microsoft's Kinect for video games, the power-hungry technology has yet to become mainstream in computers or mobile devices.
