Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
In order to be better understood from the technical scheme that the embodiment of the present invention provides, also the more preferable technical scheme with the embodiment of the present invention contrasts, and the most simply introduces implementation of the prior art.
As shown in Fig. 2-1, it is assumed that the interface visual window of certain application program shows the list items of longitudinal arrangement, in window visual range, at most can accommodate 6 list items.When user moves the focus on list items first, first list items highlights, and represents that this list items is in selected state, it is thus achieved that operation focus, now, is equivalent to operation focus and is positioned at the position at " list items 1 " place, as shown in Fig. 2-2；And when user sends, by remote controller, the instruction moving to next list items, operation focus can move to the position at " list items 2 " place, as Figure 2-3.After user sends the instruction of multiple " moving to next list items " continuously, operation focus can be moved to the position at " list items 6 " place, as in Figure 2-4, that is, operation focus has been shifted to the bottom of interface visual window.Now, if user continues to send the instruction of " moving to next list items ", and still have other list items in current application program, then operation focus will be fixed on window bottom, and list items scrolls up simultaneously.For example, with reference to Fig. 2-5, for Fig. 2-4, the invariant position of operation focus, but the list items being in selected state has been changed to list items 7, and meanwhile, list items 1 has been removed from the visual range of window.After continuing to send the instruction of " moving to next list items ", similar with said circumstances, operation focus position is the most constant, and list items scrolls up.Therefore, as described in the background art, the sight line of user will rest on the bottom of window for a long time.And the improvement that above-mentioned this situation is carried out by the embodiment of the present invention just.
Firstly the need of explanation, in embodiments of the present invention, the executive agent related to includes remote controller and intelligent television, and the process that realizes of technical solution of the present invention is the interaction of the two.Wherein, remote controller is for sending signal by button or the touch display screen that slides.Intelligent television is used for receiving remote controller signal, and according to remote controller signal, current application program is carried out corresponding operating.The application program that the present embodiments relate to is to be loaded in application program such as file manager, channel list etc. on intelligent television, that have list display interface.The list display interface of this application program for same a line or with string in show the optional list items of at least two, each list items is according to preset order arrangement, and the total quantity of list items exceeds the maximum that can accommodate list items quantity in interface visual window.For the ease of describing, below from the angle of intelligent television, the embodiment of the present invention is introduced.
With reference to Fig. 3, it is shown that the flow chart of the focus control method embodiment one of the list display interface of a kind of intelligent television of the present invention.Including:
S301: receive remote controller control signal and resolve；
Above-mentioned remote controller control signal can be that user presses the physical button of normal remote control and sends, it is also possible to is that user's remote controller that touch screen controls that slides sends.The application program of intelligent television resolves after receiving remote controller signal, analysis result can be to move up or down a list items, can also be to move a list items to the left or to the right, it is also possible to show next display page showing these list items details that this list items links.
S302: whether the analysis result judging remote controller signal is that display focus is moved to target column list item；If it is, perform next step；If it does not, end flow process.
If in the display interface of definition application, the list items at the front focus place performing remote controller control signal is the current list item.For the list of longitudinal arrangement in visual windows, above-mentioned target column list item can be a upper list items, it is also possible to be next list items.For list transversely arranged in visual windows, above-mentioned target column list item can be a list items on the left side, it is also possible to a list items on the right.
S303: determine target column list item serial number in whole list；
Said sequence numbered target column list item serial number in list items total quantity.Above-mentioned list items total quantity is the list items total quantity of list shown by above-mentioned interface visual window.
If it is to say, have a lot of list items selected for user in an application program, the quantity of these list items determines that, and each list items also determines that in the order of display, therefore, is equivalent to each list items and has respective numbering.This numbering belongs to the build-in attribute of of list items itself, will not change because of the change of the factors such as operation focus.Therefore, after determining target column list item, it is possible to determine this target column list item serial number in list items total quantity.Such as, the current list item is the 4th, then, after receiving the control signal of " moving to next column list item ", the serial number of target column list item should be just the 5th.
S304: according to the maximum that can accommodate list items quantity in the total quantity of list items and interface visual window, it is judged that whether the serial number of target column list item meets the first prerequisite；If it is, perform next step；If it does not, carry out other operations.
S305: display focus is fixed on the middle position of interface visual window, and is rolled to target column list item show that the position at focus place shows.
That is, in embodiments of the present invention, sight line in order to avoid user rests on the bottom of screen for a long time, certain condition can be pre-set, for meeting the list items of this condition, when needs obtain display focus, display focus can be fixed on the middle position of interface visual window, in this manner it is possible to make the sight line most of the time of user concentrate on this middle position, such that it is able to the cervical vertebra alleviating user to a certain extent is tired.Wherein, about so-called middle position, can be typically a certain nominated bank of list items column, or a certain appointment row that list items is expert at.
Specifically, for list items transversely arranged in interface visual window, display focus is fixed on the appointment row of same a line.This arranges with the appointment of a line can be to get rid of first row and last string successor one optional list items column in interface visual window, can arrange according to Consumer's Experience feedback data, cervical vertebra the most comfortable is made, however it is not limited to position, visual windows middle as what kind of position best suited ergonomics in.
In like manner, for the list items of longitudinal arrangement in interface visual window, display focus is fixed on the formulation row of same string.This can be to get rid of in interface visual window arbitrary optional list items after the first row and last column to be expert at the nominated bank of string, can arrange according to Consumer's Experience feedback data, however it is not limited to position, visual windows middle.
Which specifically at row can pre-define.Such as, if each list items is to show in same string, then each list items is a line, is exactly this situation as shown in Fig. 2-1.At this point it is possible to middle position is defined as the third line, etc..Certainly, if each list items shows in the same row, then each list items is string, and similar with afore-mentioned, I will not elaborate.In a word, after defining middle position, can be according to the maximum that can accommodate list items quantity in the total quantity of list items and interface visual window, generate a Rule of judgment, afterwards, for each target column list item, as long as its serial number meets this Rule of judgment and just display focus can be fixed on this middle position, and target column list item is rolled to this middle position, it is allowed to and shows that focus position overlaps.
For the above-mentioned Rule of judgment being better described in the embodiment of the present invention, first below by a specific example, the process that implements in the embodiment of the present invention is introduced in detail.
Assume that list items sum is 15, longitudinal arrangement in visual windows, namely show in same string, and in visual windows, the maximum quantity of open ended list items is 6, and assume that the middle position pre-defined is the 4th row.The most in embodiments of the present invention, in an initial condition, display focus still can be given tacit consent to and occurs in first list items and be expert at, and as shown in Fig. 2-2, when moving to next column list item, remains and shows that focus moves to list items 2 and is expert at.After display focus is moved to the 4th row, if needing to continue to move to next column list item, that is the serial number determining target column list item is 5, then this target column list item of numbered 5 is it is possible to meet the first preset condition, now, it is possible to display focus is fixed on the position at the 4th row place, simultaneously, list items is scrolled up so that list items 5 occurs in the position at display focus place, as shown in Fig. 4-1.Meanwhile, list items 5 obtains display focus, that is, now if the user while press operation buttons such as " determinations " on remote controller to send instruction, then intelligent television side will will reveal whether the details interface of this list items 5 correspondence.Certainly, after list items 5 scrolls up, list items 1 will remove interface visual window, and meanwhile, list items 7 enters interface visual window.When continuing to move to next column list item, the position remaining display focus is fixed on the 4th row, target column list item is scrolled up, it is made to overlap with the position at display focus place, and obtain display focus, it was in the list items removal interface visual window of the first row before Tong Shi, and the newest list items enters into the bottom line of interface visual window.Until the 13rd row obtain display focus, the 14th, 15 row the most together enter in interface visual window, as shown in the Fig. 4-2.It is altogether 15 due to list items, therefore, be equivalent to whole list items the most showed in interface visual window, now, when user needs to move to next column list item, just directly display focus can be moved to list items 14 be expert at, as shown in Fig. 4-3, namely show that focus occurs in the 5th row, when being further continued for moving to next column list item, then directly display focus can be moved to last column, overlap, as shown in Fig. 4-4 with list items 15 position.
In a word, in the above example, during user's alternative column list item, it is 4 to 13 these 10 list items for list items serial number, it is all to obtain display focus in fourth line, therefore, it can the realization so that user and be fixed on the middle position of visual windows for a long time, for the corner location such as the bottom relative to visual windows, can alleviate user uses eyestrain.
Visible by above-mentioned example, setting about concrete Rule of judgment, this several respects factor of maximum quantity that can accommodate list items in definition to middle position, list items total quantity, visual windows is relevant, therefore, particularly as the setting that can carry out Rule of judgment according to factors above.A kind of alternative embodiment as the present invention, it is assumed that the list items sum of current interface visual windows display list is m；The serial number of above-mentioned target column list item is x；The maximum that can accommodate list items quantity in above-mentioned interface visual window is n；The specifying row or be that y, y meet condition: 2≤y≤n-1 with the nominated bank of the string serial number in visual windows can accommodate list items quantity of above-mentioned same a line.Then combining described previously, the concrete Rule of judgment set just may is that y≤x≤m-(n-y).It is to say, in above-mentioned steps S304, it is judged that whether the serial number of target column list item meets the first prerequisite, particularly as follows:
Judge whether serial number x of target column list item meets: y≤x≤m-(n-y).
Certainly, in actual applications, typically directly middle position can be orientated as and be in row or the row in centre position.If it is, the maximum n that can accommodate list items quantity in interface visual window is even number, in interface visual window, serial number y specifying the nominated bank arranged or with string of same a line that display focus is fixing, meet condition: y=n/2.
If the maximum n that can accommodate list items quantity in described interface visual window is odd number, in interface visual window, serial number y specifying the nominated bank arranged or with string of same a line that display focus is fixing, meet condition: y=(n+1)/2.
With reference to Fig. 5, it is shown that the schematic flow sheet of another alternative embodiment of focus control method of the list display interface of a kind of intelligent television of the present invention, on the basis of embodiment illustrated in fig. 3 one, also include:
S306: according to the maximum that can accommodate list items quantity in the total quantity of list items and interface visual window, it is judged that whether the serial number of target column list item meets the second prerequisite；If it is, execution next step.
Alternatively, the list items sum assuming list is m, the serial number of target column list item is x, the maximum that can accommodate list items quantity in interface visual window is n, appointment row with a line or the nominated bank with the string serial number in visual windows can accommodate list items quantity is y, and meets condition: 2≤y≤n.Then in above-mentioned steps S306, it is judged that whether the serial number of described target column list item meets the second prerequisite, particularly as follows:
Judge that the serial number of target column list item is whether x meets: 1≤x≤y-1；Or m-(n-y)≤x≤m.
S307: display focus is moved to target column list item in the physical location of visual windows.
Above-mentioned steps S306 and step S307 are really other operating procedures in embodiment one described in step S304.
Below, as a example by channel list, in conjunction with concrete numerical value, technique scheme of the present invention is described in detail, it is assumed that the list items sum m=20 of channel list；The serial number of target column list item is x；Interface visual window can accommodate the maximum n=5 of channel list item quantity.
If channel list is longitudinal arrangement in interface visual window, focus is set and is fixed on the nominated bank of same string of visual windows serial number y=3 in visual windows can accommodate list items quantity.Then, when x=1,2,3,18,19,20, display focus moves to list items in the physical location of interface visual window；When 4≤x≤17, it is rolled to target column list item show that focus is fixed the 3rd row at place and shown.
