Abstract

In a state in which any one of selection buttons is selected (state in which a color is reversed), a touch panel in a controller is operated, and, the selected state of the selection button is released when an operation signal from the above controller is corresponding to a moving trajectory from a gray zone to another gray zone through a cancellation zone. Thereby, unnatural feeling at operation caused by distance between a finger position on the touch panel of the controller and a position of the selection button in the selected state is reduced or eliminated.

Claims

1. A display operation device, comprising:

an operation unit which transmits an operation signal including position information corresponding to a position on a display screen of a monitor; and

a control unit which is connected to the monitor, displays a plurality of selection sections at predetermined positions on the display screen, sets a selection section to a selected state when the position information of the operation signal sent from the operation unit corresponds to any one of the plurality of selection sections in a state where the plurality of selection sections are displayed, sets release areas at positions away from each of the plurality of selection sections on the display screen and between the plurality of selection sections, and releases the selected state when the operation signal including the position information corresponding to an inside of the release area is received in the selected state.

3. A display operation device according to claim 1, further comprising a notification signal transmission unit which is operated when the control unit receives the operation signal including the position information corresponding to a position at a predetermined distance away from one of the selection sections on the display screen, and transmits a predetermined notification signal.

4. A display operation device according to claim 3, wherein the notification signal transmission unit changes the notification signal gradually or in step as the position on the display screen corresponding to the position information approaches one of the selection sections.

2. A display operation device, comprising:

an operation unit which transmits an operation signal including position information according to a position on a display screen of a monitor; and

a control unit which is connected to the monitor, displays a plurality of selection sections at predetermined positions on the display screen, sets a selection section to a selected state when the position information of the operation signal sent from the operation unit corresponds to any one of the plurality of selection sections in a state where the plurality of selection sections are displayed, sets maintenance areas respectively corresponding to the plurality of selection sections, in predetermined ranges on the display screen which ranges each include one of the plurality of selection sections, maintains a state of the display screen in a state thereof before receiving the operation signal, when the position information of the operation signal from the operation unit corresponds to a position within the maintenance area, and, further, changes the set ranges of the maintenance area based on predetermined conditions.

5. A display operation device, comprising:

an operation unit which transmits an operation signal including position information according to a position on a display screen of a monitor; and

a control unit which is connected to the monitor, displays a plurality of selection sections at predetermined positions on the display screen, sets a selection section to a selected state when the position information of the operation signal sent from the operation unit includes the selection section and corresponds to an area corresponding to the selection section, sets release areas and maintenance areas at positions away from each of the plurality of selection sections on the display screen and between the plurality of selection sections, and sets the selected state into a non-selected state, at least one of when the position information is displaced from a position in a release area corresponding to a first selection section to a position in a maintenance area corresponding to a second selection section, and when the position information is displaced from a position in a maintenance area corresponding to the first selection section to a position in a release area corresponding to the second selection section.

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

the control unit controls a color of the selection section, according to whether the selection section is in a selected state or a non-selected state.

7. A display operation device according to claim 6, wherein the control unit changes the color of the selection section in the selected state according to a distance from a current position, which is expressed by the position information, to a position of the selection section.

8. A display operation device according to claim 5, wherein the control unit controls a size of the maintenance area according to an operating state.

9. A display operation device according to claim 8, wherein the operation unit is a touch panel, and the operating state is a shape of a contact surface on the touch panel.

10. A display operation device according to claim 8, wherein the operating state is a magnitude of vibration which influences on operation of the operation unit.

11. A display operation device according to claim 10, wherein the magnitude of the vibration which influences on the operation of the operation unit is the magnitude of vibration of a vehicle in which the display operation device is installed.

12. A display operation device according to claim 5, wherein the display operation device further comprises a notification signal output section, and the control unit controls the notification signal output section in the selected state of the selection section according to the distance from a current position, which is expressed by the position information, to a position of the selection section.

13. A display operation device according to claim 12, wherein

the notification signal output section is a voice output device, and a voice output from the voice output device is changed in the selected state of the selection section according to the distance from the current position, which is expressed by the position information, to the position of the selection section.

14. A display operation device according to claim 12, wherein

the notification signal output section is a vibration output device, and vibration output from the vibration output device is changed in the selected state of the selection section according to the distance from the current position, which is expressed by the position information, to the position of the selection section.
