Device, method, and graphical user interface for moving a current position in content at a variable scrubbing rate

An electronic device, comprising:

• a display;
• a 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:
• displaying a progress icon in a predefined area on the display, wherein the progress icon is configured to move in a first predefined direction on the display;
• providing a first piece of content with the electronic device;
• indicating a current position within the first piece of content with the progress icon;
• concurrently displaying with the progress icon a multi-purpose content navigation icon at a first location on the display;
• and,
• while providing the first piece of content with the electronic device:
• detecting a first contact with the touch-sensitive surface at a first location on the touch-sensitive surface that corresponds to the first location of the multi-purpose content navigation icon on the display for at least a predetermined time period;
• while continuing to detect the contact at the first location on the touch-sensitive surface, moving the current position within the first piece of content at a predefined scrubbing rate;
• detecting movement of the contact, wherein movement of the contact comprises a first component of movement on the touch-sensitive surface in a direction that corresponds to movement on the display parallel to the first predefined direction;
• and
• responding to detecting the movement of the contact by
• while continuing to detect the contact and while detecting the first component of movement increasing, moving the current position within the first piece of content at a variable scrubbing rate, wherein the variable scrubbing rate varies at least in part in accordance with the first component of movement on the touch-sensitive surface;
• and
• maintaining display of the multi-purpose content navigation icon at the first location on the display.

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 device to:

• display a progress icon in a predefined area on the display, wherein the progress icon is configured to move in a first predefined direction on the display;
• provide a first piece of content with the electronic device;
• indicate a current position within the first piece of content with the progress icon;
• concurrently display with the progress icon a multi-purpose content navigation icon at a first location on the display;
• and,
• while providing the first piece of content with the electronic device:
• detect a first contact with the touch-sensitive surface at a first location on the touch-sensitive surface that corresponds to the first location of the multi-purpose content navigation icon on the display for at least a predetermined time period;
• while continuing to detect the contact at the first location on the touch-sensitive surface, move the current position within the first piece of content at a predefined scrubbing rate;
• detect movement of the contact, wherein movement of the contact comprises a first component of movement on the touch-sensitive surface in a direction that corresponds to movement on the display parallel to the first predefined direction;
• and
• respond to detecting the movement of the contact by:
• while continuing to detect the contact and while detecting the first component of movement increasing, moving the current position within the first piece of content at a variable scrubbing rate, wherein the variable scrubbing rate varies at least in part in accordance with the first component of movement on the touch-sensitive surface;
• and
• maintaining display of the multi-purpose content navigation icon at the first location on the display.
