Abstract

The present invention provides a portable information device including a display for displaying information, a key input unit having a plurality of keys to which numbers are assigned, a key input receiver for receiving an input of a key of the key input unit, a first detector for detecting contact of an object and the contact position, a second detector for detecting a change in the contact position detected by the first detector, and a display controller for controlling scrolling of a screen of the display, when the key input receiver receives an input of a key and the second detector detects a change in the contact position, on the basis of the number assigned to the received key and the change in the contact position.

Claims

1. A portable information device comprising:

a display for displaying information;

a key input unit having a plurality of keys to which numbers are assigned;

a key input receiver for receiving an input of a key of the key input unit;

a first detector for detecting contact of an object and the contact position;

a second detector for detecting a change in the contact position detected by the first detector; and

a display controller for controlling scrolling of a screen of the display, when the key input receiver receives an input of a key and the second detector detects a change in the contact position, on the basis of the number assigned to the received key and the change in the contact position.

2. The portable information device according to claim 1, wherein the display controller defines the direction of the change in the contact position as the scrolling direction of the screen.

3. The portable information device according to claim 1, wherein the display controller defines the number assigned to the key as the amount of scrolling of the screen.

4. The portable information device according to claim 3, wherein the display displays information by the line, and the amount of scrolling is the number of lines.

5. The portable information device according to claim 3, wherein the display displays information allowed to be displayed at one time by the screen, and the amount of scrolling is the number of screens.

6. The portable information device according to claim 1, wherein the display controller controls scrolling of a screen of the display when the first detector detects contact between after the key input receiver receives an input of a key until the second detector detects a change in the position.

7. The portable information device according to claim 1, wherein the display controller continues to control scrolling when the second detector detects a change in the contact position and a predetermined key is depressed.

8. The portable information device according to claim 1, wherein the display controller controls scrolling of a screen of the display, when a change in the contact position is detected within a predetermined time after the key input receiver receives an input of a key, on the basis of the number assigned to the received key and the change in the contact position.

9. A portable information device comprising:

a reproducer for reproducing information;

a key input unit having a plurality of keys to which numbers are assigned;

a key input receiver for receiving an input of a key of the key input unit;

a first detector for detecting contact of an object and the contact position;

a second detector for detecting a change in the contact position detected by the first detector; and

a reproduction controller for controlling reproduction of the reproducer, when the key input receiver receives an input of a key and the second detector detects a change in the contact position, on the basis of the number assigned to the received key and the change in the contact position.

10. The portable information device according to claim 9, wherein the reproduction controller defines the number assigned to the key as the reproducing speed.
