Device, method, and graphical user interface for orientation-based parallax display

A method includes displaying three or more display layers, the three or more display layers including at least a first display layer and a second display layer. The method further includes shifting display positions of at least the first display layer and the second display layer. Shifting the display positions includes applying a first (x,y) offset to the display position of the first display layer, and applying a second (x,y) offset to the display position of the second display layer, wherein the first (x,y) offset and the second (x,y) offset are determined in accordance with a calculated difference between a detected orientation of the electronic device and a reference orientation. The method further includes redisplaying the three or more display layers after the shifting of the display positions. At least one of the first display layer and the second display layer is responsive to touch input gestures.
