Abstract: Methods and systems for incorporating handwritten information into a text or graphics document as text data, image data or command cues received through a positional input digitizing recognizer, such as a digitizer pad. In a data entry mode, a unit of data is inserted and accepted for placement at a designated location. In a recognition mode, the data is recognized as legible text with optional embedded edit or other commands, or it is recognized as graphics and accepted into an associated image frame. Information interpreted as commands can be executed as editing commands to control addition, deletion or movement of text within the document, as well as font or type size change or color change and the like. The invention may take advantage of features native to the particular application.

Abstract: A vehicle navigation system is provided wherein a preselected route is established in terms of a sequence data and processing means computes sequence action data based on lineal distances between landmarks, such as junctions, and movement detecting means, such as a turn detection, for detecting movement only around an approached landmark in order to synchronize position with the landmark. In accordance with the invention, it is unnecessary to store all geographic data about a region to be traversed during a journey and further computation can be extremely efficient without reliance at any time on detection of direction with respect to magnetic north or other fixed, remote reference. All needed information is incorporated into data related only to distance travelled by the vehicle between landmarks and movement around (e.g., turns) an approached landmark.
