Does anyone know what the Taptic Engine effect is supposed represent? Apple Watch - Feels like a finger tapping or nudging you MacBook Trackpad - Emulates the movement of the classic trackpad without actually moving iPhone 6S/6S+ - ??? A silent toaster ding saying "Thanks for waiting, your action is now complete" ??? I'm not trying to make a joke here. In relation to the Watch and Trackpad then I simply don't understand the physical response I'm supposed to associate this with. So I'm curious what others view that Taptic effect is supposed to be emulating.
