iPhone 6 might let you 'feel' objects on screen

The next killer feature on Apple's expected iPhone 6 could be a display that provides tactile feedback to users - giving users the impression, for instances, of a physical keyboard on a flat touchscreen.
This latest iPhone 6 rumor stems from a report Wednesday on Chinese site Laoyaoba, which said so-called "haptics" technology will be added into the new device.
Haptics technology is built into devices to create tactile feedback or vibrations so a user feels something when touching the screen of a mobile device. For instance, someone could feel the sensation of clicking a button or moving an object around the screen when using the technology.
