Abstract

An information display device (100) is provided, which includes a distance setting module (20) configured to set a distance, a closest approach position estimating module (32) configured to estimate a closest approach position (Psa, Psb) of a first ship (S) and a closest approach position (Pa, Pb) of a second ship (Ea, Eb) at a time point when the first and second ships (S, Ea, Eb) approach each other the closest, based on navigational information of the ships (S, Ea, Eb), and a display controlling module (35) configured to cause a display screen to display the estimated closest approach position (Pa, Pb) of the second ship (Ea, Eb), a risk area (Aa, Ab), and current positions of the ships (S, Ea, Eb), the risk area (Aa, Ab) formed into a circle based on the set distance, centering on the estimated closest approach position (Psa, Psb) of the first ship (S).

Claims

1. An information display device, comprising:

a distance setting module configured to set a distance;

a closest approach position estimating module configured to estimate a closest approach position of a first ship and a closest approach position of a second ship at a time point when the first and second ships approach each other the closest, based on navigational information of the first and second ships; and

a display controlling module configured to cause a display screen to display the estimated closest approach position of the second ship, a risk area, and current positions of the first and second ships, the risk area formed into a circle based on the set distance, centering on the estimated closest approach position of the first ship.

2. The information display device of claim 1, wherein the display controlling module causes the display screen to display a closest approach period of time that is an estimated period of time until the first and second ships reach the closest approach positions, respectively.

3. The information display device of claim 2, wherein the display controlling module causes the display screen to display the closest approach time period near one of the closest approach positions.

4. The information display device of claim 1, wherein the display controlling module causes the display screen to display a predicted track of the second ship as a line connecting the current position and the closest approach position of the second ship.

5. The information display device of claim 1, wherein the closest approach position of the second ship and the risk area are displayed by the display controlling module when overlapped with each other.

6. The information display device of claim 1, wherein the closest approach position of the second ship and the risk area are displayed by the display controlling module when a closest approach period of time that is an estimated period of time until the first and second ships reach the closest approach positions, respectively, is below a given period of time.

7. The information display device of claim 1, further comprising a target ship selecting module configured to select, in a case where the second ship includes a plurality of second ships, one of the displayed second ships to be a target ship,

wherein the display controlling module causes the display screen to display in an emphasized manner the risk area corresponding to the selected target ship and the closest approach position of the target ship.

8. The information display device of claim 1, further comprising a target ship selecting module configured to select, in a case where the second ship includes a plurality of second ships, one of the displayed second ships to be a target ship,

wherein, among the risk areas and the closest approach positions regarding the plurality of displayed second ships, the display controlling module causes the display screen to only display the risk area corresponding to the selected target ship and the closest approach position of the selected target ship.

9. The information display device of claim 1, wherein the display controlling module causes the display screen to display a trace of at least one of the closest approach positions of the first and second ships, corresponding to a time lapse.

10. The information display device of claim 1, wherein, in a case where the second ship includes a plurality of second ships, the display controlling module causes the display screen to display the risk area and the closest approach position of the second ship, in different modes among the plurality of second ships.

11. The information display device of claim 1, wherein, in a case where the second ship includes a plurality of second ships having different levels of risk, the display controlling module causes the display screen to display at least one of the risk area and the closest approach position of the second ship, in different modes among the plurality of second ships.

12. An information display device, comprising a processor programmed to at least:

set a distance,

estimate a closest approach position of a first ship and a closest approach position of a second ship at a time point when the first and second ships approach each other the closest, based on navigational information of the first and second ships, and

cause a display screen to display the estimated closest approach position of the second ship, a risk area, and current positions of the first and second ships, the risk area formed into a circle based on the set distance, centering on the estimated closest approach position of the first ship.

13. A method of displaying information, comprising:

estimating a closest approach position of a first ship and a closest approach position of a second ship at a time point when the first and second ships approach each other the closest, based on navigational information of the first and second ships;

generating a risk area formed into a circle based on a set area distance, centering on the estimated closest approach position of the first ship; and

displaying the estimated closest approach positions of the first and second ships, the generated risk area, and current positions of the first and second ships.
