Abstract

To enable an input unit inputting information showing a contact position when in a first mode to be used as a pointing device inputting information showing a movement quantity of the contact position when in a second mode. Information is displayed on a display unit, a touch on a detection surface disposed in superposition on a display area of the display unit is detected, and a signal based on a contact status is inputted to a processing unit from an input unit, information given from the input unit is set as information showing a contact position when in a first mode and as information showing a movement quantity of the contact position when in a second mode, the signal is switched over.

Claims

1. A device comprising:

a display unit displaying information;

an input unit configured to detect at least a touch on a detection surface disposed in superposition on a display area of the display unit, and inputting a signal based on a contact status to a processing unit; and

a switching module configured to switch over the signal transmitted to the processing unit based on a first mode or a second mode, wherein the signal inputted from the input unit is regarded in a first mode as the signal showing a contact position, and in a second mode, regarded as the signal showing a movement quantity of the contact position.

2. The device according to claim 1, further comprising a connecting unit connecting an external display,

wherein when the external display is connected to the connecting unit, the switching module switches over the signal to be sent in the second mode.

3. The device according to claim 1, further comprising a display control unit stopping the display on the display unit when in the second mode.

4. The device according to claim 1, further comprising:

a display control unit displaying a predetermined control image on the display unit when in the second mode; and

a processing unit conducting control assigned to the control image when the input unit does an input for selecting the control image.

5. A method by which a computer executes:

displaying information on a display unit;

detecting at least a touch on a detection surface disposed in superposition on a display area of the display unit, and inputting a signal based on a contact status to a processing unit; and

setting the signal given from the input unit as the signal showing a contact position when in a first mode and as the signal showing a movement quantity of the contact position when in a second mode, and switching over the signal transmitted to the processing unit.

6. The method according to claim 5, wherein when the external display is connected, the signal is switched over to the signal showing the movement quantity of the contact position when in the second mode.

7. The method according to claim 5, wherein the computer stopping the display on the display unit when in the second mode.

8. The method according to claim 5, wherein the computer executes:

displaying a predetermined control image on the display unit when in the second mode; and

conducting control assigned to the control image when the input unit does an input for selecting the control image.

9. A storage medium readable by a computer, storing a program operated by the computer and making the computer execute:

displaying information on a display unit;

detecting at least a touch on a detection surface disposed in superposition on a display area of the display unit, and inputting a signal based on a contact status to a processing unit; and

setting the signal given from the input unit as the signal showing a contact position when in a first mode and as the signal showing a movement quantity of the contact position when in a second mode, and switching over the signal transmitted to the processing unit.

10. The storage medium according to claim 9, wherein when the external display is connected, the signal is switched over to the signal showing the movement quantity of the contact position when in the second mode.

11. The storage medium according to claim 9, wherein the computer stopping the display on the display unit when in the second mode.

12. The storage medium according to claim 9, wherein the computer executes:

displaying a predetermined control image on the display unit when in the second mode; and

conducting control assigned to the control image when the input unit does an input for selecting the control image.
