Abstract

There is provided a display unit including a touch panel disposed on a display screen of a display panel to detect a touch position of a pointing device, operation being conducted by touching a touch operation member displayed on the screen. The display unit includes a sensor for sensing a pushing pressure caused when touching the touch operation member, and a control section for conducting first processing concerning the touch operation member pushed by the pointing device when the pressure sensed by the sensing unit satisfies a first predetermined pressure condition, and conducting second processing concerning the touch operation member, when the pushing pressure has changed from the first condition to a second one. Upon the change from the first condition to the second one, a function of moving the screen in a direction of pushing pressure caused by the pointer is executed by the second processing.

Claims

1. A display unit with touch panel including a touch panel disposed on a display screen of a display panel to detect a touch position of a pointer, operation being conducted by touching a touch operation member displayed on the display screen, the display unit with touch panel comprising:

a sensor for sensing a pushing pressure P caused by the pointer when touching the touch operation member;

moving means for moving said display screen provided with said touch panel in a direction of the pushing pressure on said display screen; and

a control section for conducting first processing concerning the touch operation member pushed by the pointer when the pressure P sensed by said sensor satisfies a relation P1≦

P<

P2 with respect to previously set pressures P1 and P2 (where P1<

P2), and conducting second processing concerning the touch operation member pushed by the pointer when the pushing pressure P has changed from P1≦

P<

P2 to P2≦

P,

wherein

when the pushing pressure P satisfies the relation P1≦

P<

P2, the display concerning said touch operation member is changed to be different by said first processing so that the display screen provided with said touch panel is moved in a direction of the pushing pressure, a moving quantity of the display screen being changed continuously according to an increase of the pushing pressure, and

when the pushing pressure P has changed from P1≦

P<

P2 to P2≦

P where the touch operation member is regarded as pressed, a function of moving the display screen provided with said touch panel in a direction of pushing pressure caused by the pointer is executed and a predetermined processing assigned to the touch operation member is executed by the second processing, a changing rate of the moving quantity of the display screen responsive to the increase of the pushing pressure in said second processing being different from a changing rate of the moving quantity of the display screen in said first processing.

2. The display unit with touch panel according to claim 1, wherein

the function of moving the display screen provided with said touch panel in a direction of pushing pressure caused by the pointer is conducted by the first processing, and

instead of the function of moving the display screen provided with said touch panel in a direction of pushing pressure caused by the pointer, a function of moving the display screen provided with said touch panel in a direction opposite to that of pushing pressure caused by the pointer is conducted by the second processing.

3. The display unit with touch panel according to claim 1, further comprising:

a memory for storing audio data; and

a speaker for reproducing the audio data, wherein in addition to processing of making display concerning the touch operation member different, processing of generating a voice message from the speaker based on the audio data concerning the touch operation member read out from the memory is further conducted by the first processing.

4. The display unit with touch panel according to claim 1,

wherein a moving quantity of the display screen in said second processing is changed continuously according to an increase of the pushing pressure P, and

wherein the changing rate of the moving quantity of the display screen in said second processing increases rapidly as compared with the changing rate of the moving quantity in said first processing.

5. A display unit with touch panel including a touch panel disposed on a display screen of a display panel to detect a touch position of a pointer, operation being conducted by touching a touch operation member displayed on the display screen, the display unit with touch panel comprising:

a sensor for sensing a pushing pressure P caused by the pointer when touching the touch operation member;

moving means for moving said display screen provided with said touch panel in a direction of the pushing pressure on said display screen;

a control section for conducting first processing concerning the touch operation member pushed by the pointer when the pressure P sensed by said sensor satisfies a relation P1≦

P<

P2 with respect to previously set pressures P1 and P2 (where P1<

P2), and conducting second processing concerning the touch operation member pushed by the pointer when the pushing pressure P has changed from P1≦

P<

P2 to P2≦

P,

wherein when the pushing pressure P satisfies the relation P1≦

P<

P2, the display concerning said touch operation member is changed to be different by said first processing, and when the pushing pressure P has changed from P1≦

P<

P2 to P2≦

P where the touch operation member is regarded as pressed, a function of moving the display screen provided with said touch panel in a direction of pushing pressure caused by the pointer is executed and a predetermined processing assigned to the touch operation member is executed by the second processing; and

said display unit further comprising;

a storage section for storing data that represents a relation between a position and a height as regards contents displayed on the display screen, wherein said control section reads height data corresponding to coordinates of a detected touch position from said storage section, and conducts processing of moving the display screen provided with said touch panel with a drive quantity depending upon the height data by the first processing.

6. A display unit according to claim 5, wherein the moving of the display screen provided with said touch panel by the first processing is processing of moving the display screen to a predetermined first height, when a transition is effected from a state in which the pointer touches an area where the touch operation member is not displayed to a state in which the pointer touches an area where the touch operation member is displayed, and the moving of the display screen provided with said touch panel by the second processing is processing of moving the display screen provided with said touch panel to a predetermined second height wherein said first height is relatively higher than a height of the display screen provided with said touch panel in an immediately preceding state, and said second height is relatively lower than a height of the display screen provided with said touch panel in an immediately preceding state.

7. A display unit with touch panel including a touch panel disposed on a display screen of a display panel to detect a touch position of a pointer, operation being conducted by touching a touch operation member displayed on the display screen, the display unit with touch panel comprising:

a sensor for sensing a pushing pressure P caused by the pointer when touching the touch operation member;

moving means for moving said display screen provided with said touch panel in a direction of the pushing pressure on said display screen;

a memory for storing audio data;

a speaker for reproducing the audio data; and

a control section for conducting first processing concerning the touch operation member pushed by the pointer when the pressure P sensed by said sensor satisfied a relation P1≦

P<

P2 with respect to previously set pressures P1 and P2 (where P1<
