Using touchless technology which it says is ideal for taking selfies or groupies, Crunchfishs GoCam app lets users trigger photos or videos from a distance with just hand gestures. 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 Microsofts Kinect for video games, the power-hungry technology has yet to become mainstream in computers or mobile devices.
