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: 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: This disclosure pertains to devices, methods, systems, and computer readable media for generating and/or interpreting image metadata to determine input parameters for various image processing routines, e.g., filters that distort or enhance an image, in a way that provides an intuitive experience for both the user and the software developer. Such techniques may attach the metadata to image frames and then send the image frames down an image processing pipeline to one or more image processing routines. Image metadata may include face location information, and the image processing routine may include an image filter that processes the image metadata in order to keep the central focus (or foci) of the image filter substantially coincident with one or more of the faces represented in the face location information. The generated and/or interpreted metadata may also be saved to a metadata track for later application to unfiltered image data.
