Device having touch panel, radar apparatus, plotter apparatus, ship network system, viewpoint changing method and viewpoint changing program
First Claim
1. A device having a touch panel that is touched by an operator, comprising:
- a display unit configured to display map data on a display screen;
a detector configured to detect a first touch operation from the operator on the touch panel on the display screen and a second touch operation from the operator on the touch panel on the display screen, the first touch operation being a touch operation of which a position is fixed, the second touch operation being a touch operation of which a position is changed; and
a controller configured to;
obtain the position of the first touch operation where an altitude above a sea surface on the map data is 0 m;
obtain a first rotational axis perpendicular to the sea surface that intersects the position of the first touch operation;
obtain a second rotational axis parallel to the sea surface that intersects the position of the first touch operation; and
simultaneously rotate a viewpoint of the map data centering on the second rotational axis based on a change amount of a distance from the position of the first touch operation to the position of the second touch operation, and rotate the viewpoint centering on the first rotational axis.

Abstract
A touch panel device displays a nautical chart as map data on a display screen. The touch panel device detects a first touch operation on the display screen and a second touch operation on the display screen, the first touch operation being a touch operation of which a position is fixed, the second touch operation being a touch operation of which a position is changed. The touch panel device obtains a rotational axis parallel to the sea surface based on the position of the first touch operation, and rotates a viewpoint of the map data centering on the rotational axis based on a change amount of a distance from the position of the first touch operation to the position of the second touch operation.

13. A viewpoint changing method, comprising:
-
displaying map data on a display screen; detecting a first touch operation from an operator on a touch panel on the display screen and a second touch operation from the operator on the touch panel on the display screen, the first touch operation being a touch operation of which a position is fixed, the second touch operation being a touch operation of which a position is changed; obtaining the position of the first touch operation where an altitude above a sea surface on the map data is 0 m; obtaining a first rotational axis perpendicular to the sea surface that intersects the position of the first touch operation; obtaining a rotational axis parallel to the sea surface that intersects the position of the first touch operation; and simultaneously rotating a viewpoint of the map data centering on the second rotational axis based on a change amount of a distance from the position of the first touch operation to the position of the second touch operation, and rotating the viewpoint centering on the first rotational axis.

14. A device having a touch panel that is touched by an operator, comprising:
-
a display unit configured to display map data on a display screen; a detector configured to detect a first touch operation from the operator on the touch panel and a second touch operation from the operator on the touch panel on the display screen; and a controller configured to; obtain a position of the first touch operation where an altitude above a sea surface on the map data is 0 m; obtain a first rotational axis perpendicular to the sea surface that intersects the position of the first touch operation; obtain a second rotational axis parallel to the sea surface that intersects the position of the first touch operation; and simultaneously rotate a viewpoint of the map data centering on the first rotational axis based on a rotate amount of the second touch operation with respect to the position of the first touch operation, and rotate the viewpoint centering on the second rotational axis based on a change amount of a distance from the position of the first touch operation to a position of the second touch operation.
