Patent 7587087 was granted and assigned to Nokia on September, 2009 by the United States Patent and Trademark Office.
The invention relates to on-line handwriting recognition. At least one auxiliary line is displayed on a touch sensitive panel. Each of the auxiliary lines constitutes a portion of more than one character of a character set. A character of the character set is drawn on the touch sensitive panel by completing one of the at least one auxiliary line into the character. The drawn character is recognized on the basis of said completion. The invention allows handwriting recognition that is significantly more reliable and easier to use than prior art techniques.
