Abstract

There is provided an electronic device, handwriting processing method, and handwriting processing program, that allows a user to more conveniently and less cumbersomely input an instruction for scrolling. An electronic device includes a touchscreen panel and a processor for receiving a handwritten character input via the touchscreen panel, and causing the touchscreen panel to display the handwritten character thereon. When a predetermined shape is input via the touchscreen panel the processor causes the touchscreen panel to scroll a screen.

First claim

The invention claimed is:

1. An electronic device comprising:
a touchscreen panel; and
a processor for receiving a handwritten character input via said touchscreen panel, and causing said touchscreen panel to display said handwritten character thereon,
in response to a predetermined shape being input via said touchscreen panel, said processor causing said touchscreen panel to scroll a screen by a width, as seen in a scroll direction, of an area surrounding a handwritten character input after an immediately previous scroll operation is performed and before said predetermined shape is input,
wherein:
when said predetermined shape is input, said processor determines whether there is a blank area having said width behind said predetermined shape;
if said blank area having said width is present, said processor scrolls said screen; and
if said blank area having said width is absent, said processor does not scroll said screen.

2. The electronic device according to claim 1 , wherein said processor determines that said predetermined shape is input when said processor detects that a period is input.

3. The electronic device according to claim 1 , wherein said processor determines that said predetermined shape is input when said processor detects that a comma is input.

4. A handwriting processing method performed in an electronic device including a touchscreen panel and a processor, comprising the steps of:
receiving, by said processor, a handwritten character input via said touchscreen panel;
causing, by said processor, said touchscreen panel to display said handwritten character thereon; and
in response to a predetermined shape being input via said touchscreen panel, causing, by said processor, said touchscreen panel to scroll a screen by a width, as seen in a scroll direction, of an area surrounding a handwritten character input after an immediately previous scroll operation is performed and before said predetermined shape is input,
wherein:
when said predetermined shape is input, said processor determines whether there is a blank area having said width behind said predetermined shape;
if said blank area having said width is present, said processor scrolls said screen; and
if said blank area having said width is absent, said processor does not scroll said screen.
