Abstract

A touch panel device displays a nautical chart and symbols indicating waypoints arranged on the nautical chart. The touch panel device detects touch operations at two or more positions on the display screen and touched positions thereof. The touch panel device creates an area on the display screen based on the two or more detected touched positions, specifies one or more of the symbols located within the created area, and performs cut processing and the like on the one or more of the symbols.

Claims

1. A device having a touch panel, comprising:

a display unit configured to display, on a display screen, an image and symbols arranged on the image;

a detector configured to detect touch operations at two or more positions on the display screen and touched positions thereof; and

a controller configured to create an area on the display screen based on the two or more touched positions detected by the detector, and specify one or more of the symbols located within the created area.

2. The device having the touch panel of claim 1, wherein among the one or more of the symbols within the created area, the controller specifies the symbol that is closest to a center of the area by differentiating the symbol from the other symbols.

3. The device having the touch panel of claim 1, wherein the controller sets the touched positions used in creating the area to be latest positions of the touch operations at the two or more positions respectively.

4. The device having the touch panel of claim 3, wherein even after the detector no longer detects the touch operations, the controller keeps the one or more of the symbols specified, the one or more of the symbols located within the area that is created based on the latest touched positions.

5. The device having the touch panel of claim 1, wherein the controller performs, on the specified one or more of the symbols, either one of cut processing in which the one or more of the symbols are removed and saved temporarily, and copy processing in which the one or more of the symbols are copied.

6. The device having the touch panel of claim 5, wherein when the touch operations are performed so that the two or more touched positions approach the one or more of the symbols, the controller performs either one of the cut processing and the copy processing on the one or more of the symbols.

7. The device having the touch panel of claim 6, wherein after the controller performs either one of the cut processing and the copy processing, when touch operations are performed at two or more touched positions so that the positions are separated from a predetermined position, the controller performs paste processing in which the one or more of the symbols are pasted to the predetermined position.

8. The device having the touch panel of claim 1, wherein when the touch operations are performed so that the two or more touched positions are separated from the one or more of the symbols, the controller performs processing in which only the surrounding of the one or more of the symbols is displayed enlarged on the display unit.

9. The device having the touch panel of claim 1, comprising a memory configured to store nautical chart information

wherein the controller displays a position of a ship and the symbols on a nautical chart based on positional information received from a GNSS sensor.

10. A radar apparatus, comprising the device having the touch panel of claim 9.

11. A plotter apparatus, comprising the device having the touch panel of claim 9.

12. A ship network system, comprising the device having the touch panel of claim 9.

13. A symbol specifying method, comprising:

displaying, on a display screen, an image and symbols arranged on the image;

detecting touch operations at two or more positions on the display screen and touched positions thereof; and

creating an area on the display screen based on the two or more touched positions detected by the detecting the touch operations, and specifying one or more of the symbols located within the created area.

14. (canceled)

15. A device having a touch panel, comprising:

a display unit configured to display, on a display screen, an image and symbols arranged on the image;

a detector configured to detect touch operations on the display screen and a touched position thereof; and

a controller configured to create an area on the display screen based on the touched position detected by the detector, and specify one or more of the symbols located within the created area.
