Apple Could Bring This Popular Apple Watch Feature To iPhone and iPad

 Earlier this year it emerged, through patent filings, Apple is exploring the idea of bringing the Digital Crown from the Apple Watch to other mobile devices.

Now two more patent applications have been published, suggesting Apple is continuing to take a serious look at bringing the UI feature to future iPhone and iPad models.
The initial filing, revealed in July, showed how the crown could be used to control volume, resize text, take a photo or scroll through menus. A second in August demonstrated how it could be used to give iOS a 3D UI that would make it possible to switch between a cube of common apps like Mail, Safari, Phone and Calendar.
However, the patents unearthed today by Patently Apple (via 9to5Mac), show how haptic feedback could be added to the Digital Crown if it were deployed on iOS devices.
