Touch panel, control method, program, and storage medium
First Claim
1. Apparatus comprising:
- a touch panel which monitors operation positions entered by a user on a display screen;
a mark display part, coupled to said touch panel, which displays marks indicating operation target positions on the display screen such that the densities of the marks along a predetermined direction differ as a function of the position along the predetermined direction such that at least three mark densities different from each other are established;
an operation position reader part, coupled to said touch panel, which reads operation positions entered on said touch panel;
a relative position acquisition part which operatively couples said mark display part and said operation position reader part and which obtains a relative position of an operation position of an entered mark as read by said operation position reader part relative to the display position of the entered mark as displayed by said mark display part; and
a calibration part, coupled to said operation position reader part, which calibrates the operation position in a new operation based on the relative positions.

Abstract
A touch panel that improves operability for users is provided. The touch panel monitors and calibrates operation positions made by a user on a display screen is provided, including a mark display part that displays marks indicating operation target positions on the display screen such that the densities of the marks in the main scanning line direction or sub-scanning line direction are different in response to positions of the directions; an operation position reader part that reads operation positions on the touch panel by the user; a relative position acquisition part that obtains relative positions of the operation positions from the mark made by the user relative to a display position of the mark; and a calibration part that calibrates the position of a new operation by the user different from an operation applied to the mark based on the relative positions.

10. A method comprising the steps of:
-
obtaining calibration functions in a system having a touch panel for monitoring and calibrating operation positions entered by a user on a display screen, the calibration functions corresponding to each of at least two segments having respective distances along a predetermined direction on the display screen, the distances not being equal and the predetermined direction being based at least in part on usage angle information, wherein the predetermined direction is a direction selected from the group consisting of a main scanning line direction and a sub-scanning line direction; reading operation positions entered on the touch panel; and calibrating the operation position using one of said obtained calibration functions for the segment corresponding to the read operation position and determining the input coordinates.

11. A program product comprising:
a computer usable medium having computer readable program code embodied therein for execution on a computer having a touch panel for monitoring and calibrating operation positions entered by a user on a display screen, the computer readable program code in said program product being effective when executing to; display a plurality of marks indicating operation target positions on the display screen such that the distance between at least three successive marks along a predetermined direction progressively lessens along the predetermined direction, wherein the predetermined direction is a direction selected from the group consisting of a main scanning line direction and a sub-scanning line direction; read operation positions entered on the touch panel; obtain relative positions of the read operation positions relative to the display position of the displayed marks; and calibrate the operation position in a new operation different from an operation applied when the relative positions were obtained.

12. A program product comprising:
a computer usable medium having computer readable program code embodied therein for execution on a computer having a touch panel for monitoring and calibrating operation positions entered by a user on a display screen, the computer readable program code in said program product being effective when executing to; obtain respective calibration functions corresponding to each of at least two segments having distances that differ from each other along a predetermined direction on the display screen, wherein the predetermined direction is a direction selected from the group consisting of a main scanning line direction and a sub-scanning line direction; read operation positions entered on the touch panel; and calibrate the operation position using one of said obtained calibration functions for the segment corresponding to the read operation position and determine the input coordinates.
