Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships

An electronic device, comprising:

• a display;
• a touch-sensitive surface;
• one or more sensors to detect intensities of contacts with the touch-sensitive surface;
• 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:
• detecting a contact on the touch-sensitive surface;
• determining a respective location of the contact on the touch-sensitive surface;
• wherein the respective location on the touch-sensitive surface has a respective dynamic range for detecting intensity of the contact;
• determining an intensity of the contact on the touch-sensitive surface at the respective location;
• detecting a change in intensity of the contact;
• and
• in response to detecting the change in intensity of the contact at the respective location on the touch-sensitive surface, adjusting an output of the device, wherein:
• in accordance with a determination that the respective location has a first dynamic range, the output is adjusted in accordance with:
• the change in the intensity of the contact at the respective location;
• and
• a first input-output mapping of intensity to response that corresponds to the first dynamic range;
• and
• in accordance with a determination that the respective location has a second dynamic range that is different from the first dynamic range, the output is adjusted in accordance with:
• the change in the intensity of the contact at the respective location;
• and
• a second input-output mapping of intensity to response that corresponds to the second dynamic range, wherein the second input-output mapping is different from the first input-output mapping.
