    Abstract: In some examples, an electronic device including a touch screen can sense a stylus proximate to the touch screen. For example, the user can draw or write with the stylus to create a simulated drawing or simulated handwriting displayed on the touch screen. In some examples, the electronic device can sense a series of “points” corresponding to the location of the stylus over time while the drawing/writing input was provided. In some situations, noise in the stylus data can cause the electronic device not to sense one or more noisy points included in the drawing or handwriting input. In some examples, the electronic device can interpolate the noisy points based on sensed points before and/or after the time of the skipped points.

    Abstract: A device receives a user input that corresponds with a sequence of characters. In response to the user input, the device displays simulated handwritten text that includes varying the appearance of characters in the simulated handwritten text based on variations in handwritten text of a respective user. In response to receiving the user input and in accordance with a determination that a first criterion is met, a first character in the sequence of characters has a first appearance that corresponds to the appearance of the first character in handwritten text of the respective user. In accordance with a determination that a second criterion is met, the first character in the sequence of characters has a second appearance that corresponds to the appearance of the first character in handwritten text of the respective user. The second appearance of the first character is different than the first appearance of the first character.

    Abstract: Methods, systems, and computer-readable media related to a technique for providing handwriting input functionality on a user device. A handwriting recognition module is trained to have a repertoire comprising multiple non-overlapping scripts and capable of recognizing tens of thousands of characters using a single handwriting recognition model. The handwriting input module provides real-time, stroke-order and stroke-direction independent handwriting recognition for multi-character handwriting input. In particular, real-time, stroke-order and stroke-direction independent handwriting recognition is provided for multi-character, or sentence level Chinese handwriting recognition. User interfaces for providing the handwriting input functionality are also disclosed.

    Abstract: An electronic device includes a touch-sensitive surface. The electronic device includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The device detects a first touch input on the touch-sensitive surface, and, in response to detecting the first touch input on the touch-sensitive surface, determines a first intensity applied by the first touch input on the touch-sensitive surface. The device identifies a first intensity model identifier from a plurality of predefined intensity model identifiers, and, in accordance with the first intensity applied by the first touch input on the touch-sensitive surface and one or more thresholds associated with the first intensity model identifier, determines a first touch characterization parameter. Subsequent to determining the first touch characterization parameter, the device sends first touch information to the first software application. The first touch information includes the first intensity model identifier and the first touch characterization parameter.
