Embodiment
With reference to the accompanying drawings embodiments of the invention are described.In the following description, many details have been set forth to make person of ordinary skill in the field more fully understand and realize the present invention.But be apparent that person of ordinary skill in the field, realization of the present invention can not have some in these details.In addition, should be understood that, the present invention is not limited to introduced specific embodiment.On the contrary, can consider to implement the present invention by the combination in any of characteristic sum key element described below, and no matter whether they relate to different embodiments.Therefore, aspect below, feature, embodiment and advantage use for illustrative purposes only, and should not regard key element or the restriction of claim as, unless clearly proposed in the claims.
For such as in-vehicle multi-media system, menu changing method according to an embodiment of the invention will be described now.
According to the present invention, all menus and menu item thereof are stored in system in the mode of tree structure.Fig. 1 is exemplified with this tree-like storage structure.
In the present embodiment, when user selects a certain menu to search a certain function, system shows the menu item of this menu, and the current set of menu item such as can highlighted state display.For this current menu item, system determines its position in described tree structure.
The menu operation of systems axiol-ogy user.Such as, user can search the function of expectation by mobile menu item, such as, move menu item by the directionkeys on keypad or touch-screen.At this moment, the variable quantity of system-computed movement, then searches the position of the menu item that will move in described tree structure according to the position of the current set of menu and described variable quantity.
Such as, in the tree-like storage structure illustrated in Fig. 1, when the position of the current set of menu item is node 5, according to the variable quantity of the movement calculated, the position of the menu item that will move to can be obtained, such as node 6,7 or 8, then, the current set of menu item is switched to the menu item that will move to.
As shown in Figure 1, node 5,6,7 and 8 is the child node of node 2, and node 2 is the position of above-mentioned user-selected a certain menu.In other words, node 5,6,7,8 is the position of the various menu item of this menu.
When the current set of menu item has been in the bottom of this menu, user still continues to move down menu item, such as, as shown in Figure 1, when the position of system determination the current set of menu item is node 8, then system finds the child node under the brotgher of node of node 2 according to this tree structure, the position of the menu item that namely will move to, it is such as the child node 9 of the node 3 shown in Fig. 1, then, the current set of menu item is switched to the menu item that will move to, the current set of menu item by a certain menu is switched to the menu item of the menu at the same level of this menu.
But when system cannot find the position of the menu item that will move to from this tree structure, then system keeps the current set of menu item constant.
In addition, system is after determining the position of the current set of menu item in described tree structure, information from master menu along described tree structure to all or part of menu item involved by the current set of menu item is provided, such as, shows the information comprising path, title etc. from master menu to the current set of menu item.Such as, when the position of the current set of menu item is positioned at node 8, show from node 1 by way of all menu items involved by node 2 to node 8.
Below, with reference to Fig. 2, the embody rule of menu changing method and the example of algorithm realization are according to an embodiment of the invention described.
First, the menu item (step S201) of a certain menu is shown.
Then, system judges that user is left or the menu item that moves right (step S202).
When user is moved to the left menu item, system judges whether also have menu item (step S203) on the left of the current set of menu item.Such as, determine the memory address of the current set of menu item, calculate the variable quantity of movement, and subtract computing according to the memory address of variable quantity to the current set of menu item of movement, then judge whether the memory address that computing obtains has corresponding menu item.
If there is menu item (i.e. "Yes") on the left of the current set of menu item, such as, if the memory address that computing obtains has corresponding menu item, then system shows the menu item (step S201) of this correspondence.
If there is no menu item (i.e. "No") on the left of the current set of menu item, such as, if the memory address that computing obtains does not have corresponding menu item, then system judges whether his father's menu is master menu (step S204) further.Such as, determine the memory address of father's menu of the current set of menu item, and judge whether it corresponds to master menu.
If his father's menu is master menu (i.e. "Yes"), then system does not change the current set of menu item (step S208).
If his father's menu is not master menu (i.e. "No"), then system judges whether the left side of his father's menu has adjacent menus (step S205) further.Such as, computing is subtracted to the memory address of father's menu of the current set of menu item, then judge whether the memory address that computing obtains has corresponding fraternal menu.
Such as, when the left side of the father's menu judging the current set of menu item does not have adjacent menus (i.e. "No"), if the memory address that computing obtains does not have corresponding fraternal menu, then process proceeds to step S208.
When there is adjacent menus (i.e. "Yes") in the left side of the father's menu judging the current set of menu item, such as, if the memory address that computing obtains has corresponding fraternal menu, then system shows the menu item (step S206) of this fraternal menu.
Then, system judges whether user operates (step S207) the menu item of this adjacent menus.
If user does not carry out any operation during to this ("No"), then ended process.
If user is to when this has been operation ("Yes"), then process turns back to step S202, namely again judges that user is left or moves right menu item.
When user is moved to the left menu item, repeat above process.When user moves right menu item, processing procedure and above process similar, only such as memory address is carried out and aforementioned contrary increasing computing, repeats no more herein.
Above about the embodiment of the addressing operation of system, be exist on the basis of tree-like storage structural relation between each menu and menu item, increase or subtract computing to search the memory address of the menu item that will move to the memory address of the current set of menu item.But embodiments of the present invention are not limited thereto, between each menu of any structure and menu item, the storage mode of tree-like storage structure and the addressing mode of correspondence all can be applicable in the present invention.
Alternatively, when preparing the menu item of a certain menu of display, system judges the maximum number whether number of the menu item of this menu exceedes viewing area and normally show; When the number of menu item does not exceed the maximum number that viewing area normally shows, with normal size (size 1) display menu item; When the number of menu item exceedes the maximum number that viewing area normally shows, with reduced size (size 2), be namely less than the size of normal size, display menu item.
Size 1 and size 2 can be default, or can be arranged by user.In addition, the menu item shown with size 2 can clearly be recognized by user.
Preferably, when the number of menu item exceedes the maximum number that viewing area normally shows, system starts enlarged display area.Such as, the menu item in enlarged display area is with normal size (size 1) display, and the menu item outside enlarged display area shows with reduced size (size 2).
After carrying out menu blocked operation, when the menu item that will show on screen changes, the display size entering the menu item of this enlarged display area is greater than the display size of the menu item leaving this enlarged display area.Such as, enter the menu item of this enlarged display area with normal size (size 1) display, and the Submenu Items leaving this enlarged display area shows with reduced size (size 2).
Specifically, system will calculate the size of each menu item according to the data of size 1 and size 2 and the information such as font, font size, and the menu item number that can hold respectively outside enlarged display area in and enlarged display area.Refer again to the position of enlarged display area, system can determine which menu item is presented in enlarged display area, and which menu is presented at outside enlarged display area.
Such as shown in Fig. 3, in the leftward space of enlarged display area, system, according to the size in this region and each menu item size, calculates and can hold 8 menu items, so 1 ~ No. 8 menu item is shown in left side; The size of system according to enlarged display area and the size of menu item, calculate and can hold 5 menu items, so ensuing 5 menus 9 ~ No. 13 menu items are shown in enlarged display area; On the right side of enlarged display area, algorithm is identical with algorithm on the left of enlarged display area.
Referring now to Fig. 4, the application of menu display and the example of algorithm realization in menu changing method are according to an embodiment of the invention described.
In step S401, system judges whether that all menu items can be presented on screen by normal size.
When judged result is yes, with normal size display menu item (step S406).
When judged result is no, display enlarged display area (step S402), the menu item wherein in enlarged display area shows with normal size, and the menu item outside enlarged display area shows with reduced size, but can clearly be differentiated.
Then, respond user operation and carry out menu blocked operation (step S403).Can refer to the description of composition graphs 1,2 above herein.
After carrying out menu blocked operation, system call interception enters or leaves the display size of the menu item of enlarged display area.Leave the menu item of enlarged display area with reduced size display (step S404).Enter the menu item of enlarged display area with normal size display (step S405).
Like this, when needing the menu item number of display to exceed the maximum number that viewing area normally shows, by reducing the display size of menu item, can once show more menu item as much as possible, decrease paging, thus decrease the number of times of page layout switch, namely decrease the interaction times of user and system.And, by arranging the moveable enlarged display area of user, even if when the display size of menu item reduces, also can not vision addressability be reduced, can contribute to the function that user searches needs easily.
Although the foregoing describe exemplary embodiment of the present invention, the present invention is not limited thereto.Person of ordinary skill in the field can make various change and amendment, and does not depart from the spirit and scope of the present invention.Scope of the present invention is only defined by the claims.
