Abstract: A system and method that is able to recognize a user's natural drawing of geometric shapes. The system and method is able to process single-stroke and multi-stroke geometric shapes. It can also apply implicit and user defined constraints to the geometric shapes. The system and method applies these constraints at the vector component level rather than the primitive level. It does this by breaking down both the geometric shapes and constraints on a vector component level. This allows the system and method to handle a larger number of geometric shapes and constraints. After applying the constraints to the geometric shapes at the vector component level, the system and method outputs smooth geometric shapes that incorporated both the implicit and user defined constraints.

Abstract: Disclosed is a device for inputting symbols in an entry field. An example of the device includes an interface unit having a touch screen and a module for processing graphics objects. The module may include a detection unit for detecting a start and an end of a current graphics object being input; a storage unit for storing graphics data corresponding to the input graphics object; a recognition unit for generating a list of candidate strings of symbols from the graphics data, each candidate string being associated with a pertinence value; and an insertion unit for inserting into the entry field a string selected by the user from the list, a data group comprising the graphics data, the candidate strings, the pertinence values, and an identifier of the selected string being stored during a predetermined duration.
