1. A method for online character recognition of Arabic text, the method comprising the procedures of: receiving handwritten Arabic text from a user in the form of handwriting strokes; sampling said handwriting strokes to acquire a sequence of two-dimensional point representations thereof, including associated temporal data; geometrically pre-processing and extracting features on said point representations; detecting delayed strokes and word-parts in said pre-processed point representations; projecting said delayed strokes onto the body of said word-parts; constructing feature vector representations for each said word-part, thereby generating an observation sequence; generating at least one word-part dictionary indexed in accordance with word features, wherein: said at least one word-part dictionary is a sub-dictionary of a dictionary that includes a set of valid words; and said at least one word-part dictionary contains words having a predetermined integer number of word-parts; and determining the word in part according to said at least one word-part dictionary with maximum probability given said observation sequence, resulting in a list of word probabilities; wherein each said word-part refers to an intra-connected portion of a word, which is bounded on each side by a minimal amount of space in the text.
