Devices, methods, and graphical use interfaces for manipulating user interface objects with visual and/or haptic feedback

A method, comprising:

• at a device with at least one non-transitory memory, a touch screen, a camera, and one or more processors in communication with the at least one non-transitory memory, the touch screen, and the camera:
• displaying, via the touch screen, a first virtual display layer including contents;
• detecting, via the touch screen, at least a portion of touch;
• in response to an aspect of the touch being detected to surpass a threshold, displaying, via the touch screen, a plurality of markings in a second virtual display layer that appears to have a lesser depth than the first virtual display layer, where at least a portion of the second virtual display layer is at least partially translucent so that at least a portion of the contents of the first virtual display layer is visible through the at least portion of the second virtual display layer;
• detecting, via the touch screen, another touch on at least one of the plurality of marking;
• and
• in response to detection of the another touch on the at least one of the plurality of marking in the second virtual display layer that appears to have the lesser depth than the first virtual display layer, displaying, via the touch screen, a movement of one or more of the plurality of markings in the second virtual display layer;
• and
• performing a zoom operation on the at least portion of the contents of the first virtual display layer without performing the zoom operation on the plurality of markings in the second virtual display layer, where the zoom operation is performed based on the movement of the one or more of the plurality of markings in the second virtual display layer, and the at least portion of the second virtual display layer is at least partially translucent so that a result of the zoom operation on the at least portion of the contents of the first virtual display layer is visible through the at least portion of the second virtual display layer.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with at least one non-transitory memory, a touch screen, a camera, and one or more processors, cause the electronic device to:

• display, via the touch screen, a first virtual display layer including contents;
• detect, via the touch screen, at least a portion of touch;
• in response to an aspect of the touch being detected to surpass a threshold, display, via the touch screen, a plurality of markings in a second virtual display layer that appears to have a lesser depth than the first virtual display layer, where at least a portion of the second virtual display layer is at least partially translucent so that at least a portion of the contents of the first virtual display layer is visible through the at least portion of the second virtual display layer;
• detect, via the touch screen, another touch on at least one of the plurality of marking;
• and
• in response to detection of the another touch on the at least one of the plurality of marking in the second virtual display layer that appears to have the lesser depth than the first virtual display layer, display, via the touch screen, a movement of one or more of the plurality of markings in the second virtual display layer;
• and
• perform a zoom operation on the at least portion of the contents of the first virtual display layer without performing the zoom operation on the plurality of markings in the second virtual display layer, where the zoom operation is performed based on the movement of the one or more of the plurality of markings in the second virtual display layer, and the at least portion of the second virtual display layer is at least partially translucent so that a result of the zoom operation on the at least portion of the contents of the first virtual display layer is visible through the at least portion of the second virtual display layer.
