Abstract

According to one embodiment, an electronic apparatus includes a touch-screen display, a memory, a display process module, and a change module. The memory is configured to store time-series information indicative of loci and an order of handwriting of a plurality of strokes handwritten on the touch-screen display. The display process module is configured to display loci corresponding to the plurality of strokes, on the touch-screen display, based on time-series information. The change module is configured to change time-series information in accordance with an editing operation to the plurality of strokes on the touch-screen display.

Claims

1. An electronic device comprising:

a touch-screen display;

a memory configured to store time-series information indicative of loci and an order of handwriting of a plurality of strokes handwritten on the touch-screen display;

a display process module configured to display loci corresponding to the plurality of strokes, on the touch-screen display, based on time-series information; and

a change module configured to change time-series information in accordance with an editing operation to the plurality of strokes on the touch-screen display.

2. The electronic device of claim 1, wherein the display process module is configured to display loci based on time-series information changed by the change module.

3. The electronic device of claim 1, wherein the change module is configured to insert a blank area between a first locus and a second locus in accordance with the editing operation, and to change time-series information in accordance with a movement of at least one of the first locus and the second locus.

4. The electronic device of claim 3, wherein the change module is configured to change, if a third locus corresponding to a stroke is handwritten in the blank area, time-series information corresponding to at least one of the first locus and the second locus in accordance with the third locus.

5. The electronic device of claim 3, wherein the change module is configured to set the blank area in a direction corresponding to an arrangement of the first locus and the second locus.

6. The electronic device of claim 1, wherein the change module is configured to delete information of the locus designated by the input operation from time-series information, in accordance with an input operation of designating any one of the plurality of loci.

7. A handwritten document creation method comprising:

storing time-series information indicative of loci and an order of handwriting of a plurality of strokes handwritten on a touch-screen display;

displaying loci which correspond to the plurality of strokes, on the touch-screen display, based on time-series information; and

changing time-series information in accordance with an input operation on the touch-screen display.

8. A non-transitory computer-readable medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:

storing time-series information indicative of loci and an order of handwriting of a plurality of strokes handwritten on a touch-screen display;

displaying loci which correspond to the plurality of strokes, on the touch-screen display, based on time-series information; and

changing time-series information in accordance with an input operation on the touch-screen display.
