How gesture-based apps will reshape the mobile user experience


Gesture-based Samsung Electronics' forthcoming Galaxy S4 smartphone will feature Smart Pause, which uses a phone's front-facing camera to track eye movement and allows the device to respond to users' gestures. Another technology in Samsung's S4, Air Gesture, uses the phone's camera to track hand movements to navigate tabs or move items on a screen.

These are just two examples of gesture-based, human-computer interactions that could change the way consumers engage with their devices. ABI Research estimated that 27 million mobile devices shipped in 2012 have gesture-recognition technology, a figure expected to balloon to 600 million smartphones by 2017. Not surprisingly, developers are already being offered an array of tools that could allow them to install similar capabilities inside their apps. Whether they'll take advantage of them is another matter. Feature
