We already know Apple is working on haptic technologies for mobile devices from patents in the past (here, here, and here). We also know that last-minute rumors of Finnish company Senseg’s technology being included in the third-generation iPad never came true. Another patent surfaced today giving us a look at Apple’s work with an advanced multi-tiered haptics system for iOS devices. PatentlyApple has all the details:

…today’s surprise invention packs a punch with a wildly intelligent multi-tiered haptics system. The system will actually allow an iDevice display to deform so that it could provide the user with a button, an arrow or even a geological map to physically pop right out of the screen to give it 3D depth. If that wasn’t cool enough, Apple’s patent discusses a flexible OLED display that could be used for video glasses.
