LAYOUT SWITCHING DEVICE, SCREEN GENERATING DEVICE FOR MOVING OBJECT,INFORMATION DISPLAY SYSTEM FOR MOVING OBJECT,MOVING OBJECT,AND CONTROL METHOD
First Claim
1. A layout switching device for switching, in accordance with a state of a moving object, layouts of an information screen shown to an operator of the moving object, comprising:
- a state information acquiring means for acquiring state information indicating the state of the moving object;
a state change judgment means for judging whether or not the state information is changed, every time the state information acquiring means acquires the state information;
a type information storage section for storing, for each of the layouts, type information indicating a type of the state information;
a switching necessity judgment means for judging, based on whether or not a type of changed state information is included in the type information corresponding to a current layout, whether or not switching of the layouts is required, in a case where the state change judgment means judges that the state information is changed, the type information corresponding to the current layout being stored in the type information storage section;
a rule storage section for storing a layout decision rule for deciding a layout based on the state information; and
a layout decision means for deciding the layout after switching, in a case where the switching necessity judgment means judges that switching of the layouts is required, the layout being decided based on (i) the state information acquired by the state information acquiring means and (ii) the layout decision rule stored in the rule storage section.

Abstract
In one embodiment of the present invention, a layout switching device includes: a disregard list storage section for storing, for each of display layouts, a disregard list indicating a type of state information which can be disregarded even when the state information is changed; and a disregard list comparing section for judging, in a case where the state information is changed, whether or not a type of the changed state information is indicated in the disregard list by referring to a disregard list which corresponds to a current display layout and is stored in the disregard list storage section. Further, a layout decision section decides a layout after switching, based on the latest state information and a layout decision rule, only in a case where the disregard list comparing section judges that the type of the changed state information is not included in the disregard list. This realizes a layout switching device which is capable of efficiently switching layouts of an information screen shown to an operator of a moving object in accordance with a state of the moving object.

10. A control method of a layout switching device for switching, in accordance with a state of a moving object, layouts of an information screen shown to an operator of the moving object, the control method comprising the steps of:
-
acquiring, by a state information acquiring means of the layout switching device, state information indicating the state of the moving object; judging, by a state change judgment means of the layout switching device, whether or not the state information thus acquired is changed, every time the state information is acquired in the step of acquiring the state information; judging, by a switching necessity judgment means of the layout switching device, whether or not switching of the layouts is required, based on whether or not a type of changed state information is included in type information corresponding to a current layout, in a case where the state information is judged to be changed in the step of judging state change, the type information (i) indicating a type of the state information and (ii) being stored in a type information storage section for storing, for each of the layouts, the type information; and deciding, by a layout decision means of the layout switching device, a layout after switching, in a case where it is judged, in the step of judging necessity of switching, that switching of the layouts is required, the layout being decided based on (i) the state information acquired in the step of acquiring the state information and (ii) a layout decision rule for deciding, based on the state information, the layout after switching, the layout decision rule being stored in a rule storage section for storing the layout decision rule.
