25. An article comprising: a non-transitory computer-readable medium having instructions that, when executed by a computing platform, result in execution of a method comprising: drawing one or more strokes of a desired shape using a stylus on 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 desired shape; inputting an associated data of the drawn 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 desired shape that can be used to trigger shape 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 shape recognition for the desired shape by the handwriting recognition engine upon determining the trigger stroke.
