Abstract

Disclosed is an intentional shift method for a cursor position on the input device such as a touch panel. The cursor position located by of a pen-type device is shifted intentionally. The roundness of the pen nib sometimes masks the view of the cursor position. A cursor can be shifted from the position, that is pointed by the pen nib, by stepping or continuous movement by means of changing angle of the coil in the sensor or calculating the address by the software. Figures 1(a) and 1(b) show the examples of this shift method. The bird's-eye views of the sensor built in the edge of electromagnetic-field-output pen are shown as schematic illustrations. The direction of the electromagnetic field from the built-in sensor including the coil can be changed by switching in Fig. 1(a). The sensors which have different angles are mounted in the pen nib as described in Fig. 1(b). Fig. 1(a) Fig. 1(b) By the software, the control of the cursor position can be implemented by any kind of input device. A schematic illustration of the input window is shown in Fig. 2. In the window, we can select the shift mode. If we want to shift the cursor, the values of the shift can be input in X-axis and Y-axis directions separately. Then the new address is calculated by shifting from the pen pointed position so that we can put the cursor in the favorite position.

Input method of touch panel display

Disclosed is an intentional shift method for a cursor position on the input
device such as a touch panel. The cursor position located by of a pen-type
device is shifted intentionally. The roundness of the pen nib sometimes masks
the view of the cursor position. A cursor can be shifted from the position,
that is pointed by the pen nib, by stepping or continuous movement by means of
changing angle of the coil in the sensor or calculating the address by the
software.

Figures 1(a) and 1(b) show the examples of this shift method. The bird's-eye
views of the sensor built in the edge of electromagnetic-field-output pen are
shown as schematic illustrations. The direction of the electromagnetic field
from the built-in sensor including the coil can be changed by switching in
Fig. 1(a). The sensors which have different angles are mounted in the pen nib
as described in Fig. 1(b).

By the software, the control of the cursor position can be implemented by any
kind of input device. A schematic illustration of the input window is shown in
Fig. 2. In the window, we can select the shift mode. If we want to shift the
cursor, the values of the shift can be input in X-axis and Y-axis directions
separately. Then the new address is calculated by shifting from the pen
pointed position so that we can put the cursor in the favorite position.
