19. A method comprising: drawing one or more strokes of a current desired character using a stylus on a current handwriting task area in a touch screen, wherein one of the drawn one or more strokes is a head-line stroke and is a last drawn stroke of the current desired character; inputting an associated data of the one or more strokes via the touch screen into a handwriting recognition engine; computing stroke recognition characteristics of each of the drawn one or more strokes with reference to a horizontal reference line, wherein the stroke recognition characteristics are selected from the group comprising aspect ratio and slope; determining a trigger stroke in the drawn one or more strokes of the current desired character that can be used to trigger character recognition based as a function of the computed stroke recognition characteristics of each of the drawn one or more strokes, wherein the trigger stroke is the head-line stroke which is drawn substantially parallel to the horizontal reference line; and triggering character recognition for the drawn current desired character by the handwriting recognition engine upon determining the trigger stroke.

The method of claim 19 , further comprising: providing a next handwriting task area for drawing one or more next desired character upon displaying the current candidate character in the current handwriting task area; and repeating the drawing, inputting, determining, triggering, producing, and displaying steps for the next desired character.
