Abstract

A display device that is to be connected with an information terminal includes: a video reception unit that receives video information about a screen including a cursor from the information terminal; a touch panel that brings up on display the screen based upon the video information received by the video reception unit and detects a touch position specified by a touch operation; and a transmission unit that transmits, to the information terminal, displacement quantity information corresponding to a quantity of displacement from the display position of the cursor to the touch position.

Claims

1. A display device that is to be connected with an information terminal having a display monitor, comprising:

a video reception unit that receives video information about a screen including a cursor from the information terminal;

a touch panel that brings up on display the screen based upon the video information received by the video reception unit and detects a touch position specified by a touch operation;

a resolution information reception unit that receives resolution information of the display monitor from the information terminal;

a conversion coefficient calculation unit that calculates a conversion coefficient in correspondence to a ratio of resolution of the display monitor to resolution of the touch panel based upon the resolution information received by the resolution information reception unit and resolution of the touch panel that is stored in advance;

a displacement quantity calculation unit that calculates a quantity of displacement from a display position of the cursor to the touch position;

a conversion unit that converts the quantity of displacement calculated by the displacement quantity calculation unit into a quantity of displacement on the display monitor based upon the conversion coefficient calculated by the conversion coefficient calculation unit; and

a transmission unit that transmits, to the information terminal, displacement quantity information indicating the quantity of displacement converted by the conversion unit.

2. A display device according to claim 1, wherein:

the conversion coefficient calculation unit calculates the conversion coefficient for a transverse direction and a longitudinal direction, respectively, of the touch panel;

the displacement quantity calculation unit calculates a quantity of displacement from a displacement position of the cursor to the touch position for the transverse direction and the longitudinal direction, respectively, of the touch panel; and

the conversion unit converts the quantity of displacement for the transverse direction of the touch panel into a quantity of displacement for a transverse direction on the display monitor by using the conversion coefficient in the transverse direction and also converts the quantity of displacement for the longitudinal direction of the touch panel into a quantity of displacement for a longitudinal direction on the display monitor by using the conversion coefficient in the longitudinal direction.

3. A display device that is to be connected with an information terminal, comprising:

a video reception unit that receives video information about a screen including a cursor brought up on display at a predetermined reference position from the information terminal;

a touch panel that brings up on display the screen based upon the video information received by the video reception unit and detects a touch position specified by a touch operation; and

a transmission unit that transmits, to the information terminal, displacement quantity information corresponding to a quantity of displacement from the display position of the cursor to the touch position, wherein

after completion of the touch operation, the display position of the cursor is returned to the reference position.

4. A display device according to claim 3, wherein

after completion of the touch operation, the transmission unit transmits displacement quantity information indicating a predetermined maximal quantity of displacement or a predetermined minimal quantity of displacement for the transverse direction and the longitudinal direction, respectively, of the touch panel to the information terminal, thereby returning the display position of the cursor to the reference position.

5. A display device according to claim 3, wherein:

a point of indication of the cursor is located at an end of the cursor; and

the reference position is located at an end in an orientation opposite to an orientation directed from a center of the cursor to the point of indication.

6. A display device according to claim 5, wherein:

the point of indication of the cursor is located at a left upper end of the cursor; and

the reference position is located at a right lower end of the touch panel.

7. A display device that is to be connected with an information terminal, comprising:

a video reception unit that receives an image from the information terminal; and

a touch panel that brings up on display the image received by the video reception unit and detects a touch position specified by a touch operation, wherein

in response to the touch operation, a cursor brought up on display at an outer periphery of the touch panel is displaced to the touch position and after completion of the touch operation, the cursor is returned to an original position.

8. A display device according to claim 7, wherein

after completion of the touch operation, displacement quantity information indicating a predetermined maximal quantity of displacement or a predetermined minimal quantity of displacement for the transverse direction and the longitudinal direction, respectively, of the touch panel is transmitted to the information terminal, thereby returning the display position of the cursor to the reference position.

9. A display device according to claim 7, wherein:

a point of indication of the cursor is located at a left upper end of the cursor; and

the cursor is brought up on display at a right lower end of the touch panel before the touch operation is started and after the touch operation is completed.
