According to reports emerging from Apple’s supply chain, the iPhone 6 is likely to be fitted with an advanced tactile motor capable of providing varied and better haptic feedback based on the areas on which the screen is touched.
Chinese publication Laoyaoba learned about this feature through its sources and according the report Apple is indenting to extend the feature set to app developers such that they can provide different haptic feedback through their apps.
The report claims that the new tactile motor is thrice the cost of the ones available in current-gen smartphones including the iPhone 5S. There is no proof with the report, but a patent application from Apple titled “Touch-based user interface with haptic feedback” that points at the possibility of such a feature.
Another patent vide application titled “Method and apparatus for localization of haptic feedback” was awarded to Apple in February 2013 and this particular patent describes the technology that would allow Cupertino to provide with localised tactile feedback to iPhone users.
We are not sure how this feature will work, but until then we would recommend, as always, to take such rumours with a grain of salt.
