3. A method as recited in claim 1 wherein said step of dividing said initial note area comprises: detecting a theoretical line drawn on said display by said pointing means; determining whether said theoretical line is a division gesture; and generating a header bar on said computer display for a new note area if said theoretical line is determined to be a division gesture.
3. A method as recited in claim 1 wherein said step of dividing said initial note area comprises: detecting a theoretical line drawn on said display by said pointing means; determining whether said theoretical line is a division gesture; and generating a header bar on said computer display for a new note area if said theoretical line is determined to be a division gesture. 5. A method as recited in claim 3 wherein said step of determining whether said theoretical line is a division gesture includes the following steps: determining whether there is a sample point farther from said theoretical line than a predetermined maximum distance value; determining whether the absolute value of a sum of the signed distances of said plurality of sample points from said theoretical line is greater than a predetermined maximum sum value; determining whether the absolute value of a slope of said theoretical line differs from a predetermined header bar slope by more than a predetermine maximum slope value; and determining whether either end of said theoretical line is separated from an edge of said screen by more than a predetermined maximum margin value: wherein when one of the determining steps fails, said theoretical line is not a division gesture.
