Abstract: A computing device having a touch-sensitive surface and a display, detects a stylus input on the touch-sensitive surface while displaying a user interface. A first operation is performed in the user interface in accordance with a determination that the stylus input includes movement of the stylus across the touch-sensitive surface while the stylus is detected on the touch-sensitive surface. A second operation different from the first operation is performed in the user interface in accordance with a determination that the stylus input includes rotation of the stylus around an axis of the stylus while the stylus is detected on the touch-sensitive surface. A third operation is performed in the user interface in accordance with a determination that the stylus input includes movement of the stylus across the touch-sensitive surface and rotation of the stylus around an axis of the stylus while the stylus is detected on the touch-sensitive surface.

Abstract: An electronic device with a touch-sensitive display and one or more sensors to detect signals from a stylus associated with the device: while the electronic device is in a locked state: displays a lock screen user interface on the touch-sensitive display; while displaying the lock screen user interface, detects a first input from the stylus to draw on the touch-sensitive display; in response to detecting the first input, displays, over the lock screen user interface, one or more marks of a drawing that correspond to the first input; while displaying, on the lock screen user interface, the one or more marks of the drawing: detects a second input from the stylus to display a drawing application in a restricted mode; and, in response to detecting the second input, executes the drawing application in the restricted mode and displays the one or more marks of the drawing in the drawing application.

Abstract: An electronic device displays a user interface in a first display state. The device detects a first portion of a gesture on a touch-sensitive surface, including detecting intensity of a respective contact of the gesture. In response to detecting the first portion of the gesture, the device displays an intermediate display state between the first display state and a second display state. In response to detecting the end of the gesture: if intensity of the respective contact had reached a predefined intensity threshold prior to the end of the gesture, the device displays the second display state; otherwise, the device redisplays the first display state. After displaying an animated transition between a first display state and a second state, the device, optionally, detects an increase of the contact intensity. In response, the device displays a continuation of the animation in accordance with the increasing intensity of the respective contact.

Abstract: A computing device can have a touchscreen user interface operable by different input tools, such as a finger or a stylus. The computing device can dynamically and automatically alter elements of a graphical user interface depending on the type of input tool in use. For example, a stylus can have sensors that detect touch and/or motion, and based on the sensor data, the stylus or the computing device can determine whether the stylus is currently being held in a hand. When the stylus is being held, the interface can be rendered with elements adapted for stylus input, and when the stylus is not being held, the interface can be rendered with elements adapted for finger input.

Abstract: An electronic device, with a touch-sensitive surface and a display, includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The device detects a contact on the touch-sensitive surface while a focus selector corresponding to the contact is at a respective location on the display associated with additional information not initially displayed on the display. While the focus selector is at the respective location, upon determining that the contact has an intensity above a respective intensity threshold before a predefined delay time has elapsed with the focus selector at the respective location, the device displays the additional information associated with the respective location without waiting until the predefined delay time has elapsed; and upon determining that the contact has an intensity below the respective intensity threshold, the device waits until the predefined delay time has elapsed to display the additional information associated with the respective location.

Abstract: A device that is in communication with a display and a touch-sensitive surface sends instructions to the display for displaying, concurrently, an object selection indicator and a portion of a user interface, the user interface having one or more selectable objects. The device sends instructions to the display for ceasing to display the object selection indicator and receives an input that corresponds to a first gesture. When the first gesture meets predefined navigation criteria, which includes a requirement that the first gesture has a shorter duration than a predefined time threshold, the device sends instructions for translating the user interface without redisplaying the object selection indicator.

Abstract: The present disclosure relates to user interfaces for viewing, creating, editing, and sharing content on an electronic device. A device detects a plurality of discrete inputs that includes a first input followed by a second input. In response to detecting the plurality of discrete inputs, the device performs a sequence of operations that includes a first operation that corresponds to the first input followed by a second operation that corresponds to the second input. In accordance with a determination that the plurality of discrete inputs meets an output-acceleration criteria, the first operation is performed with a first magnitude and the second operation is performed with a second magnitude that is greater than the first magnitude. In accordance with a determination that the plurality of discrete inputs does not meet the output-acceleration criteria, the first operation and the second operation are performed with the same magnitude.

Abstract: A device that is in communication with a display and a touch-sensitive surface sends instructions to the display for displaying at least a portion of a user interface, the user interface having one or more selectable objects. The device receives an input that corresponds to a first gesture detected on the touch-sensitive surface; and sends instructions to the display for displaying an object selection indicator. In response to receiving the input that corresponds to the first gesture: the device searches for a target selectable object; and sends instructions to the display for moving the object selection indicator. When a target selectable object is identified, the device moves the object selection towards the target selectable object. When a target selectable object is not identified, the device moves the object selection indicator in accordance with the first gesture.

Abstract: In any context where a user can view multiple different content items, switching among content items is provided using an array mode. In a full-frame mode, one content item is visible and active, but other content items may also be open. In response to user input the display can be switched to an array mode, in which all of the content items are visible in a scrollable array. Selecting a content item in array mode can result in the display returning to the full-frame mode, with the selected content item becoming visible and active. Smoothly animated transitions between the full-frame and array modes and a gesture-based interface for controlling the transitions can also be provided.

Abstract: An electronic device with a display, a touch-sensitive surface and one or more intensity sensors displays content. While a focus selector is over the content, the device detects a gesture on the touch-sensitive surface, the gesture including a first contact on the touch-sensitive surface and movement of the first contact across the touch-sensitive surface that corresponds to movement of the focus selector on the display.
