Abstract
A touch panel device includes a display unit, a detector, and a controller. The display unit displays, on a display screen, a nautical chart (map), and a touch panel device symbol indicating a position of the ship on the nautical chart. The detector detects rotating operation that is touch operation of rotating around the touch panel device symbol over a predetermined angle while touching the touch panel device symbol. When the detector detects the rotating operation, the controller switches a display mode to a different display mode in which a reference azimuth defining a displaying orientation of the nautical chart is different.
Claims20
An information display device, comprising:
- a display unit configured to display, on a display screen, a map and an information display device symbol indicating a position of the information display device on the map, the information display device being a movable body;
- a touch detector configured to detect rotating operation and pinch operation, the rotating operation being touch operation in which a position of one of a touch on the information display device symbol and a touch on other than the information display device symbol is rotated centering on a position of the other touch over a predetermined angle without changing the position of the other touch, the pinch operation being touch operation in which at least one of the two touches on the display screen is separated from or brought closer to the other touch;
- and
- a controller configured, when the touch detector detects the rotating operation, to switch a display mode to a different display mode in which a reference azimuth defining a displaying orientation of the map is different, and when the touch on the information display device symbol is detected, not to perform processing that is associated with the pinch operation even in a case where the touch detector detects the pinch operation.
An information display device, comprising:
- a display unit configured to display, on a display screen, a map and an information display device symbol indicating a position of the information display device on the map, the information display device being a movable body;
- a touch detector configured to detect rotating operation that is touch operation in which a position of one of a touch on the information display device symbol and a touch on other than the information display device symbol is rotated centering on a position of the other touch over a predetermined angle without changing the position of the other touch;
- and
- a controller configured, when the touch detector detects the rotating operation, to switch a display mode to a different display mode in which a reference azimuth defining a displaying orientation of the map is different.
A method of switching a display mode, comprising:
- displaying, on a display screen, a map and an information display device symbol indicating a position of the information display device on the map, the information display device being a movable body;
- detecting rotating operation that is touch operation in which a position of one of a touch on the information display device symbol and a touch on other than the information display device symbol is rotated centering on a position of the other touch over a predetermined angle without changing the position of the other touch;
- and
- switching the display mode to a different display mode in which a reference azimuth defining a displaying orientation of the map is different, when the rotating operation is detected by the detecting the rotating operation.
A program of switching a display mode, causing a computer to:
- display, on a display screen, a map and an information display device symbol indicating a position of the information display device on the map, the information display device being a movable body;
- detect rotating operation that is touch operation in which a position of one of a touch on the information display device symbol and a touch on other than the information display device symbol is rotated centering on a position of the other touch over a predetermined angle without changing the position of the other touch;
- and
- switch the display mode to a different display mode in which a reference azimuth defining a displaying orientation of the map is different, when the rotating operation is detected by the detecting the rotating operation.
