Abstract

Improved operability can be achieved in receiving a handwritten input via a touchscreen panel. An electronic device includes a touchscreen panel, a memory for storing content having at least one predetermined position set for the content, and a processor for obtaining a first touched position via the touchscreen panel, and causing the touchscreen panel to display the content thereon based on the first touched position and the predetermined position.

First claim

The invention claimed is:

1. An electronic device comprising:
a touchscreen panel;
a memory for storing content having a plurality of areas; and
a processor for obtaining a first touched position that is a contact position of a palm on said touchscreen panel,
said processor obtaining a contact position of a pen on said touchscreen panel as a second touched position,
when said processor causes said touchscreen panel to display a first area of said plurality of areas thereon at a predetermined position based on said first touched position, and in that condition said second touched position has not been input for a predetermined period of time since a last input at the second touched position, then, said processor causing said touchscreen panel to display a second area of said plurality of areas thereon at said predetermined position by scrolling said second area to said predetermined position,
wherein the processor causes said touch panel to fix a display position of the first area at the predetermined position even when the obtained contact position of the pen moves within the first area.

2. The electronic device according to claim 1 , wherein said processor:
stores said second touched position as relative to said first touched position to said memory as a first relative position; and
causes said touchscreen panel to display a predetermined area of said plurality of areas thereon at said first relative position relative to said first touched position.

3. An electronic device comprising:
a touchscreen panel;
a memory for storing content having a plurality of areas; and
a processor for obtaining a first touched position that is a contact position of a pen on said touchscreen panel,
when said processor causes said touchscreen panel to display a first area of said plurality of areas thereon at a predetermined position based on said first touched position, and in that condition said first touched position has not been input for a predetermined period of time since a last input at the first touched position, then, said processor causing said touchscreen panel to display a second area of said plurality of areas thereon at said predetermined position by scrolling said second area to said predetermined position,
wherein the processor causes said touch panel to fix a display position of the first area at the predetermined position even when the obtained contact position of the pen moves within the first area.

4. The electronic device according to claim 3 , wherein said processor causes said touchscreen panel to display said content thereon such that said first touched position matches said predetermined position.

5. The electronic device according to claim 4 , wherein said processor stores a center of a rectangle surrounding said contact position of said pen to said memory as said first touched position based on time series data of said contact position of said pen on said touchscreen panel.

6. The electronic device according to claim 1 , wherein:
said plurality of areas are each a handwritten input receivable area set for said content.

7. The electronic device according to claim 6 , wherein:
a handwritten input unreceivable area is further set for said content; and
when said processor causes said touchscreen panel to display said first area thereon at a predetermined position based on said first touched position, said processor causes said touchscreen panel to display thereon said handwritten input unreceivable area associated with said first area, and
when said processor causes said touchscreen panel to display said second area thereon at a predetermined position based on said first touched position, said processor causes said touchscreen panel to display thereon said handwritten input unreceivable area associated with said second area.

8. A method for displaying content in an electronic device including a memory for storing content having a plurality of areas, a touchscreen panel, and a processor, the method comprising the steps of:
obtaining, by said processor, a first touched position that is a contact position of a palm on said touchscreen panel;
obtaining, by said processor, a contact position of a pen on said touchscreen panel as a second touched position; and
when said processor causes said touchscreen panel to display a first area of said plurality of areas thereon at a predetermined position based on said first touched position, and in that condition said second touched position has not been input for a predetermined period of time since a last input at the second touched position, then, causing, by said processor, said touchscreen panel to display a second area of said plurality of areas thereon at said predetermined position by scrolling said second area to said predetermined position,
wherein said processor causes said touch panel to fix a display position of the first area at the predetermined position even when the obtained contact position of the pen moves within the first area.
