Gesture-equipped touch screen system, method, and computer program product

A method, comprising:

• at an electronic device with a display, a touch interface, memory, and one or more processors:
• displaying a home screen on the display, the screen including an icon associated with an application;
• with the home screen displayed, detecting a first input by a first contact on the icon;
• in response to detecting the first input, replacing the home screen with a user interface of the application;
• with the user interface of the application displayed, detecting a second input by a second contact that includes movement across the display in a direction;
• in response to detecting the second input and in accordance with a determination that the second input meets one or more criteria that is met with the second input being detected to include a movement parameter that is above a movement threshold, displaying at least a portion of the user interface of the application in a first virtual display layer that appears at a lesser depth as compared to a second virtual display layer, where the at least portion of the user interface of the application is reduced in size and is further displayed in its entirety in the first virtual display layer;
• and
• in response to detecting the second input and in accordance with a determination that the second input does not meet the one or more criteria that is met with the second input being detected to include the movement parameter that is above the movement threshold, replacing the user interface of the application with the home screen including the icon associated with the application.

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 a display and a touch-sensitive surface, cause the electronic device to:

• display a home screen on the display, the home screen including an icon that corresponds to an application;
• while displaying the home screen, detect a first input by a first contact on the icon;
• in response to detecting the first input on the icon, replace the home screen with a user interface of the application;
• while displaying the user interface, detect a second input by a second contact that includes movement across the display in a direction;
• in response to detecting the second input and in accordance with a determination that the second input meets a first one or more criteria that is met when the second input is detected to include a movement parameter that is above a movement threshold and that the second input that meets a second one or more criteria that is met when the second input is detected to include a duration parameter that is above a duration threshold, display at least a portion of the user interface of the application in a first virtual display layer that appears at a lesser depth as compared to a second virtual display layer, w here the at least portion of the user interface of the application is reduced in size and is further displayed in its entirety when displayed in the first virtual display layer;
• and
• in response to detecting the second input and in accordance with a determination that the second input meets the first one or more criteria that is met when the second input is detected to include the movement parameter that is above the movement threshold and that the second input does not meet the second one or more criteria that is met when the second input is detected to include the duration parameter that is above the duration threshold, replace the user interface of the application with the home screen including the icon that corresponds to the application.
