Devices and methods for navigating between user interfaces

A method, comprising:

• at an electronic device with a touch-sensitive display, and one or more sensors to detect intensities of contacts with the touch-sensitive display:
• displaying, on the touch-sensitive display, a user interface for a first application;
• detecting a stationary edge input that includes detecting a change in a characteristic intensity of a contact at an edge of the touch-sensitive display while the contact is at a location of a user interface element that corresponds to a respective operation in the first application;
• and,
• in response to detecting the stationary edge input:
• determining whether the stationary edge input meets system-gesture criteria;
• determining whether the stationary edge input meets application-gesture criteria;
• in accordance with a determination that the stationary edge input meets the system-gesture criteria, performing an operation that is independent of the first application without performing the respective operation in the first application, wherein:
• the system-gesture criteria include intensity criteria, including a criterion that is met when the stationary edge input includes an increase in intensity of the contact above a first intensity threshold;
• the system-gesture criteria include a location criterion that is met when the intensity criteria for the contact are met while the contact is within a first region on the touch-sensitive display;
• in accordance with a determination that the stationary edge input meets the application-gesture criteria and does not meet the system-gesture criteria, performing the respective operation in the first application that includes activation of the user interface element in the first application, instead of performing the operation that is independent of the first application;
• and
• in accordance with a determination that the stationary edge input does not meet the system-gesture criteria and does not meet the application-gesture criteria, forgoing performing the operation that is independent of the first application and the respective operation in the first application;
• wherein the method includes receiving a plurality of respective stationary edge inputs, including a respective stationary edge input that does not meet the system-gesture criteria and does not meet the application-gesture criteria, another respective stationary edge input that meets the application-gesture criteria and does not meet the system-gesture criteria, and yet another respective stationary edge input that meets the system-gesture criteria.

An electronic device, comprising:

• a touch-sensitive display;
• one or more sensors to detect intensities of contacts with the touch-sensitive display;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying, on the touch-sensitive display, a user interface for a first application;
• detecting a stationary edge input that includes detecting a change in a characteristic intensity of a contact at an edge of the touch-sensitive display while the contact is at a location of a user interface element that corresponds to a respective operation in the first application;
• and,
• in response to detecting the stationary edge input:
• determining whether the stationary edge input meets system-gesture criteria;
• determining whether the stationary edge input meets application-gesture criteria;
• in accordance with a determination that the stationary edge input meets the system-gesture criteria, performing an operation that is independent of the first application without performing the respective operation in the first application, wherein:
• the system-gesture criteria include intensity criteria, including a criterion that is met when the stationary edge input includes an increase in intensity of the contact above a first intensity threshold;
• the system-gesture criteria include a location criterion that is met when the intensity criteria for the contact are met while the contact is within a first region on the touch-sensitive display;
• and
• in accordance with a determination that the stationary edge input meets the application-gesture criteria and does not meet the system-gesture criteria, performing the respective operation in the first application that includes activation of the user interface element in the first application, instead of performing the operation that is independent of the first application;
• and
• in accordance with a determination that the stationary edge input does not meet the system-gesture criteria and does not meet the application-gesture criteria, forgoing performing the operation that is independent of the first application and the respective operation in the first application.
