Devices, Methods, and Graphical User Interfaces for Content Navigation and Manipulation

Abstract

An electronic device displays content of a first content item, wherein the first content item is one of a sequence of content items. The device detects a user input that includes movement of a contact in a respective direction on the touch-sensitive surface. In response to detecting the user input: in accordance with a determination that the user input meets item-switching criteria, the device replaces display of the first content item with display of a second content item in the sequence of content items, wherein the item-switching criteria include a criterion that is met when a characteristic intensity of the contact is above a first intensity threshold; and, in accordance with a determination that the user input does not meet the item-switching criteria, the device navigates through the content of the first content item in accordance with the movement of the contact.
