Abstract

A touch panel device includes a display unit, a detector, and a controller. The display unit displays an image (nautical chart) on a display screen. The detector detects touches at two positions on the display screen and touched positions thereof. The controller displays a distance and azimuths between the touched positions, based on the two touched positions that are detected by the detector and either one of coordinates on the image corresponding to the touched positions and information associated with the coordinates (positional information).

Claims

1. A device having a touch panel, comprising:

a display unit configured to display an image on a display screen;

a detector configured to detect touches at two positions on the display screen and touched positions thereof; and

a controller configured to display, on the display screen, point-to-point information indicating relation of information between the touched positions based on the two touched positions that are detected by the detector and either one of coordinates on the image corresponding to the touched positions and information associated with the coordinates.

2. The device having the touch panel of claim 1, wherein when the detector detects a change of one or more of the touched positions, the controller displays the point-to-point information on the display unit based on the changed one or more of the touched positions.

3. The device having the touch panel of claim 1, wherein the controller displays, at least between the two positions, a scale indicating a value of the information associated with the coordinates.

4. The device having the touch panel of claim 1, wherein when the detector no longer detects either one of the touch at one of the two positions and the touches at the two positions, the controller erases the point-to-point information from the display unit.

5. The device having the touch panel of claim 1, wherein the display unit displays either one of a map and a nautical chart, and

wherein the controller displays on the display unit, as the point-to-point information, a distance from one of the touched positions to the other touched position and an azimuth indicated by a line coupling the two touched positions.

6. The device having the touch panel of claim 1, wherein the display unit displays either one of a map and a nautical chart, and

wherein the controller displays on the display unit, as the point-to-point information, a period of time required to move a distance from one of the touched positions to the other touched position.

7. 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 on a nautical chart based on positional information received from a GNSS sensor.

8. A radar apparatus, comprising the device having the touch panel of claim 7.

9. A plotter apparatus, comprising the device having the touch panel of claim 7.

10. A ship network system, comprising the device having the touch panel of claim 7.

11. An information displaying method, comprising:

displaying an image on a display screen;

detecting touches at two positions on the display screen and touched positions thereof; and

displaying, on the display screen, point-to-point information indicating relation of information between the touched positions based on the two touched positions that are detected by the detecting the touches and either one of coordinates on the image corresponding to the touched positions and information associated with the coordinates.

12. An information displaying program of causing a computer to:

display an image on a display screen;

detect touches at two positions on the display screen and touched positions thereof; and

display, on the display screen, point-to-point information indicating relation of the information between the touched positions, based on the two touched positions that are detected by the detecting the touches and either one of coordinates on the image corresponding to the touched positions and information associated with the coordinates.
