Abstract: An electronic device detects a change in intensity of an input on an input element that includes detecting an increase in intensity followed by a decrease in intensity, and recognizes at least a portion of the change in intensity of the input as a first input event that is associated with a first operation, for example a single click operation. After recognizing the first input event, the device delays performance of the first operation while monitoring subsequent changes in intensity of the input for a second input event, wherein the delay is limited by a default delay time period. If the second event is recognized before default delay time period has elapsed, a second operation is performed and the first operation is not performed. However, if early-confirmation criteria for the first input event are met before the default delay period elapses, the first operation is performed.

Abstract: An electronic device: while displaying a first user interface, detects a first input that is consistent with a request to display a second user interface and a request to display a third user interface. In response, the device starts to display a first animated transition from the first to the second user interface. While the first animated transition is being displayed, the device detects a second input. In response, the device determines that the second input is consistent with the request to display the third user interface and whether the second input is received at a first or at a later, second time. If at the first time, the device: interrupts the first animated transition at a first point and displays a second animated transition from the first point to the third user interface. If at the second, later time, the device interrupts the first animated transition at a second point (after the first point), and displays a third animated transition from the second point to the third user interface.

After transitioning to displaying the respective prior image, the device displays, in sequence starting with the prior image, at least some of the images acquired by the camera before acquiring the representative image and at least some of the images acquired by the camera after acquiring the representative image.

Abstract: Text input is corrected on a touch-sensitive display by presenting a list of candidate words in the interface which can be selected by touch input. The candidate list can include candidate words having two or more character types (e.g., Roman, kana, kanji). In one aspect, the candidate list can be scrolled using a finger gesture. When a user's finger traverses a candidate word and the touch is released, the candidate word is inserted into a document being edited. In another aspect, characters can be erased by touching a key (e.g., a backspace or delete key) and making a sliding, swiping, or other finger gesture. A number of characters proportional to a distance (e.g., a linear distance) of the finger gesture across the display are erased. If there are characters in a text input area, those characters are erased first, followed by characters in the document being edited.
