Temporary lines for writing


Abstract
A user is provided with guidelines that are temporarily displayed with content, in order to assist the user in neatly and accurately writing electronic ink. The guidelines may appear when the user moves a writing tool, such as a stylus or pen, close to a display and writing surface. Alternately, the guidelines may appear after the user has begun to write electronic ink, so that the guidelines can correspond to the angle at which the user is writing, the size of the user's handwriting, or both. As the user writes the electronic ink onto the writing surface, the handwritten electronic ink is added to the content being rendered on the display. After the user has finished writing electronic ink and moves the writing tool away from the writing surface, the guidelines are deleted, and are not added to the displayed content. In this way, the user can employ the temporary guidelines to accurately and legibly write electronic ink into content, without the guidelines themselves becoming a permanent part of the content.

Pen-based handwritten character recognition and storage system


Abstract
The present invention is directed to an improved system and method in which a pen-sized and shaped device detects, recognizes and stores handwriting as it is written by the device. The invention employs both an active feedback network and a character recognition methodology of partitioning detected input into character components. The active feedback network continually monitors device output to determine the sufficiency of the data input. If the data input is insufficient, the device modifies its detection methodology to obtain data the device readily recognizes. Data recognition is performed in multiple asynchronous processes. Elements of individual characters are sampled by the detector. Character elements are processed and recognized on this elemental level. Recognized character elements are stored for subsequent assembly and recognition on a character level. Thus, preferably two recognition sub-processes take place, one on a character element level and another on a character level.

Component-based, adaptive stroke-order system


Abstract
An efficient and simple approach to encoding ideographic characters as sequences of input strokes or stroke categories is disclosed, wherein: each character is represented by one or more sequences of one or more components; each component corresponds to a plurality of alternative stroke sequences, each of which is associated with a probability that it will be the sequence which the user enters to specify the given component or character; and the probability associated with the user's preferred stroke sequence is automatically increased by the system when the character is selected, thus automatically adapting to a user's preferences.

Method and apparatus for recording of electronic handwriting


Abstract
According to a method for recording of electronic handwriting, a handwriting movement is digitized into a sequence of points along a writing curve that corresponds to the handwriting movement. The sequence of points is resampled by eliminating those points that are judged not to be necessary for being able to reconstruct the writing curve later with the required visual quality. A resampled representation of the writing curve is created from the points remaining--that is not eliminated--after the resampling. The resampling is carried out on successive and partially overlapping partial sequences of the points, the resampled representation of the writing curve being extended successively after resampling of a respective partial sequence.

Arabic handwriting recognition using feature matching


Abstract
An Arabic handwriting recognition system takes an input from a stylus in the form of an ordered sequence of data. The sequence of data is then processed to eliminate any noise associated with data, and subsequently strokes (or directed line segments) are extracted from the sequence of data. More analysis of the strokes is performed to transform the input data into a features vector. Next, the features vector is matched against the features of all Arabic letters using fuzzy matching and dynamic programming techniques. During this matching process, the input word is segmented into the sequence of characters that maximized the matching score. In addition, external objects (such as: single dots, double dots, triple dots, hamzas, or maddas) that are above and below Arabic letters are detected.

Character recognition


Abstract
Character recognition includes detecting a union of characters, preprocessing the union of characters, comparing the preprocessed union of characters with one or more template symbols, and applying a decision rule to either reject a template symbol or decide that the template symbol is included in the union of characters. Such preprocessing involves representing the union of characters as one or more curves, and parameterizing the curve(s); and, regarding various classes of transformation, forming one or more shapes for the curve(s). The comparing operation involves forming one or more geometric proximity measures, and determining for every shape the values of those measures between the shape and correspondingly determined shapes for the template symbols. Applying a decision rule involves selecting one or more template symbols in consideration of the values.
