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: Aspects of subject technology provide systems and methods for electronic drawing with handwriting recognition. An electronic device may include one or more processors configured to receive a modification input to an object rendered on a display, and to perform a first re-rendering of the object on the display based on the modification input. The one or more processors may further be configured to generate at least one polygon-based representation of the object based on the modification input, and to perform, based on the at least one polygon-based representation, a second re-rendering of the object on the display.
