Apple working on motion detection feature

With rival Samsung taking a lead in introducing motion detection in its S4 smartphone, Apple Inc too is reported to be working to on the same lines in a bid to bring the new feature on its future smartphones and tablets.

According to reports Apple appears to be testing out motion control features that will let people control their iPhones by moving their heads.

The feature, first reported by 9to5 Mac, was discovered in the developer version of Apple's latest mobile operating system, iOS 7, and is not yet publicly available. It is an option in the Accessibility menu that overrides the usual touchscreen controls.

It works by using the front-facing iPhone or iPad camera to detect head movements, according to the report. When on, the system automatically runs through every option on the device screen until the user selects the one he or she wants by turning his or her head to one side.

The left or right head movements can be assigned to different tasks, including returning to the main home screen, displaying notifications or activating voice assistant Siri.
