a touch-sensitive display;

memory;

one or more processors;

and one or more modules stored in memory and configured for execution by the one or more processors, the one or more modules including instructions for:

while the device is in a first user-interface state, detecting progress towards satisfaction of a user input condition needed to transition to a second user-interface state;

wherein the first user-interface state is in a first application and the second user-interface state is in a second application that is different from the first application, while the device is in the first user-interface state, indicating progress towards satisfaction of the condition by transitioning an optical intensity of one or more user interface objects associated with the second user-interface state, wherein transitioning of the optical intensity includes the one or more user interface objects appearing and increasing in optical intensity; and

transitioning the device to the second user-interface state if the condition is satisfied.

9. A portable electronic device, comprising:

means for detecting progress towards satisfaction of a user input condition needed to transition to a second user-interface state while the device is in a first user-interface state;

means for indicating progress towards satisfaction of the condition by transitioning an optical intensity of one or more user interface objects associated with the second user-interface state while the device is in the first user-interface state, wherein transitioning the optical intensity includes the one or more user interface objects appearing and increasing in optical intensity, wherein the first user-interface state is in a first application and the second user-interface state is in a second application that is different from the first application; and

means for transitioning the device to the second user-interface state if the condition is satisfied.

10. A computer readable storage medium having stored therein executable instructions, which when executed by an electronic device, cause the device to:

while the device is in a first user-interface state, detect progress towards satisfaction of a user input condition needed to transition to a second user-interface state, wherein the first user-interface state is in a first application and the second user-interface state is in a second application that is different from the first application;
