Vision-based 3-D gesture control breaks out

This could be the year 3-D gesture recognition proves it’s not just child’s play. Several years after its first consumer market appearance in the wireless gaming interface for Nintendo’s Wii, MEMS sensor-based gesture recognition is extending its reach to smartphones and is set to take hold of that most iconic of consumer interfaces: the TV remote.

Since the Wii’s 2006 release, Nintendo’s competitors have spun their own versions of 3-D gesture recognition and processing. Sony tuned the Move Playstation controller for hard-core gamers seeking pinpoint accuracy; Microsoft took the gaming interface hands-free with the Xbox Kinect.

Apple was the first to pick up on microelectromechanical sensors’ potential for building more intuitive smartphone interfaces; it added MEMS accelerometers to the iPhone in 2007 and a MEMS gyroscope in 2010. Its competitors have followed suit, and soon 3-D commands such as shake-to-undo, lift-to-answer and face-down-to-disconnect will be standard smartphone fare.

Today, consumer OEMs are adding 3-D gesture recognition across their product lines.
