Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The technical scheme that embodiment provides for a better understanding of the present invention, also the technical scheme better and embodiment of the present invention contrasts, and first by way of example implementation of the prior art is simply introduced below.
As shown in Fig. 2-1, suppose to show in the interface visual windows of certain application program the list items of longitudinal arrangement, in window visual range, can hold at most 6 list items.When user first by Focal Point Shift on list items time, first list items highlights, and represents that this list items is in selected state, obtains operation focus, now, is equivalent to operate the position that focus is positioned at " list items 1 " place, as shown in Fig. 2-2; And when user sends by remote controller the instruction that moves to next list items, operation Focus Club moves to the position at " list items 2 " place, as Figure 2-3.When user sends after the instruction of a plurality of " moving to next list items " continuously, operation Focus Club is moved to the position at " list items 6 " place, and as in Figure 2-4, also, operation focus has been moved to the below of interface visual windows.Now, if user continues to send the instruction of " moving to next list items ", and in current application program, still have other list items, operate focus and will be fixed on below of window, list items scrolls up simultaneously.For example, referring to Fig. 2-5, for Fig. 2-4, the invariant position of operation focus, but the list items in selected state has become list items 7, and meanwhile, list items 1 has been moved out of the visual range of window.Continue to send after the instruction of " moving to next list items ", similar with said circumstances, operation focal position is still constant, and list items scrolls up.Therefore, as described in the background art, user's sight line will rest on the below of window for a long time.And the improvement that the embodiment of the present invention is carried out above-mentioned this situation just.
First it should be noted that, in embodiments of the present invention, the executive agent relating to comprises remote controller and intelligent television, and the implementation procedure of technical solution of the present invention is the reciprocal process of the two.Wherein, remote controller is for sending signal by button or slip touch display screen.Intelligent television is used for receiving remote controller signal, and according to remote controller signal, current application program is carried out to corresponding operating.The application program that the embodiment of the present invention relates to is to be loaded in application program on intelligent television, that have list display interface as file manager, channel list etc.The list display interface of this application program is for showing at least two optional list items in same a line or same row, and each list items is arranged according to preset order, and the total quantity of list items exceeds the maximum that can hold list items quantity in the visual windows of interface.For convenience of description, from the angle of intelligent television, the embodiment of the present invention is introduced below.
With reference to Fig. 3, show the flow chart of focus control method embodiment mono-of the list display interface of a kind of intelligent television of the present invention.Comprise:
S301: receive remote controller control signal and resolve;
Above-mentioned remote controller control signal can be that the physical button that user presses normal remote control is sent, and can be also that user's remote controller that touch-screen controls that slides sends.The application program of intelligent television is resolved after receiving remote controller signal, analysis result can be to move up or down a list items, also can be to move to the left or to the right a list items, can also show next display page of these list items details of demonstration of this list items link.
S302: whether the analysis result that judges remote controller signal is to target column list item by demonstration Focal Point Shift; If so, carry out next step; If not, process ends.
If in the display interface of definition application, before carrying out remote controller control signal, the list items at focus place 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, can be also 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, also can the right a list items.
S303: determine the serial number of target column list item in whole list;
Said sequence is numbered the serial number of target column list item in list items total quantity.Above-mentioned list items total quantity is the list items total quantity of the shown list of above-mentioned interface visual windows.
That is to say, if having a lot of list items of selecting for users in an application program, the quantity of these list items determines, and each list items also determines in the order showing, therefore, is equivalent to each list items and has numbering separately.This numbering belongs to the build-in attribute of list items own, can not change because the variation of the factors such as operation focus.Therefore,, after having determined target column list item, just can determine the serial number of this target column list item in list items total quantity.For example, the current list item is the 4th, and, 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 holding the maximum of list items quantity in the total quantity of list items and interface visual windows, judge whether the serial number of target column list item meets the first prerequisite; If so, carry out next step; If not, carry out other operations.
S305: will show that focus is fixed on the middle position of interface visual windows, and target column list item is rolled to and shows that the position at focus place shows.
That is to say, in embodiments of the present invention, for fear of user's sight line, rest on for a long time the below of screen, can set in advance certain condition, for the list items that meets this condition, when needs obtain demonstration focus, can will show that focus is fixed on the middle position of interface visual windows, like this, just can so that user's the sight line most of the time concentrate on this middle position, thereby it is tired to alleviate to a certain extent user's cervical vertebra.Wherein, about so-called middle position, can be generally a certain nominated bank of list items column, or the list items a certain specify columns of being expert at.
Particularly, for list items transversely arranged in the visual windows of interface, will show that focus is fixed on the specify columns of same a line.This specify columns with a line can be to get rid of first row and the rear arbitrary optional list items column of last row in the visual windows of interface, can experience feedback data setting according to user, as what kind of position met ergonomics most in, make cervical vertebra the most comfortable, be not limited to position, visual windows middle.
In like manner, for the list items of longitudinal arrangement in the visual windows of interface, will show that focus is fixed on the formulation row of same row.The nominated bank of these same row gets rid of in the visual windows of interface arbitrary optional list items after the first row and last column to be expert at, and can experience feedback data setting according to user, is not limited to position, visual windows middle.
Which specifically at row, can pre-define.For example, if each list items is to show in same row, each list items is a line, is exactly this situation as shown in Fig. 2-1.Now, middle position can be defined as to the third line, etc.Certainly, if each list items in same a line, show, each list items is row, similar with afore-mentioned, no longer describes in detail here.In a word, after defining middle position, can be according to holding the maximum of list items quantity in the total quantity of list items and interface visual windows, generate a Rule of judgment, afterwards, for each target column list item, as long as meeting this Rule of judgment, its serial number just can will show that focus is fixed on this middle position, and target column list item is rolled to this middle position, make it to overlap with showing focus position.
For the above-mentioned Rule of judgment in the embodiment of the present invention is described better, first by a concrete example, the specific implementation process in the embodiment of the present invention is at length introduced below.
List of hypotheses item adds up to 15, and longitudinal arrangement in visual windows namely in same row, show, and in visual windows, the maximum quantity of open ended list items is 6, and the middle position that hypothesis pre-defines is the 4th row.In embodiments of the present invention, under initial condition, show that focus still can be given tacit consent to appear at first list items and be expert at, as shown in Fig. 2-2, while moving to next column list item, remain demonstration Focal Point Shift and be expert to list items 2.After showing that focus is moved to the 4th row, if need to continue to move to next column list item, that is to say that the serial number of determining target column list item is 5, this is numbered 5 target column list item and just may meets the first preset condition, now, just can show that focus is fixed on the position at the 4th row place, simultaneously, list items is scrolled up, make list items 5 appear at the position that shows focus place, as shown in Fig. 4-1.Meanwhile, list items 5 obtains and shows focus, and also, if now user presses on remote controller, action buttons such as " determining " is sent instruction, and intelligent television side will demonstrate the details interface of these list items 5 correspondences.Certainly, after list items 5 scrolls up, list items 1 will shift out interface visual windows, and meanwhile, list items 7 enters interface visual windows.When continuing to move to next list items, remain and show that the position of focus is fixed on the 4th row, target column list item is scrolled up, it is overlapped with the position that shows focus place, and acquisition shows focus, list items in the first row simultaneously shifts out interface visual windows, and also has new list items to enter into the bottom line of interface visual windows.Until after the 13rd row acquisition demonstration focus, the 14th, 15 row also together enter into interface visual windows, as shown in Fig. 4-2.Because list items is altogether 15, therefore, be equivalent to whole list items and all in the visual windows of interface, showed, now, when user need to move to next column list item, just can directly demonstration Focal Point Shift be expert to list items 14, as shown in Fig. 4-3, namely show that focus appears at the 5th row, while continuing again to move to next column list item, can directly will show that Focal Point Shift, to last column, overlaps with list items 15 positions, as shown in Fig. 4-4.
In a word, in above-mentioned example, in the process of user's selective listing item, for list items serial number, be 4 to 13 these 10 list items, all to obtain and show focus in fourth line, therefore, can be so that user's realization be fixed on the middle position of visual windows for a long time, for the corner location such as bottom of visual windows, can alleviate user's the kopiopia of using.
Visible by above-mentioned example, setting about concrete Rule of judgment, with in the definition of middle position, list items total quantity, visual windows, can hold this several respects factor analysis of maximum quantity of list items, therefore, specifically just can carry out according to above factor the setting of Rule of judgment.As a kind of optional embodiment of the present invention, suppose that the list items of current interface visual windows display list adds up to m; The serial number of above-mentioned target column list item is x; The maximum that can hold list items quantity in the visual windows of above-mentioned interface is n; The serial number that the specify columns of above-mentioned same a line or the nominated bank of same row can hold in list items quantity in visual windows is y, and y satisfies condition: 2≤y≤n-1., described in combination above, the concrete Rule of judgment of setting can be just: y≤x≤m-(n-y).That is to say, in above-mentioned steps S304, judge whether the serial number of target column list item meets the first prerequisite, be specially:
Whether the serial number x that judges target column list item meets: y≤x≤m-(n-y).
Certainly, in actual applications, generally can directly middle position be orientated as to row or row in centre position.Namely, if can hold the maximum n of list items quantity in the visual windows of interface, be even number, in the visual windows of interface, the specify columns of same a line that demonstration focus is fixing or the serial number y of the nominated bank of same row, satisfy condition: y=n/2.
If can hold the maximum n of list items quantity in the visual windows of described interface is odd number, in the visual windows of interface, the specify columns of same a line that demonstration focus is fixing or the serial number y of the nominated bank of same row, satisfy condition: y=(n+1)/2.
With reference to Fig. 5, show the schematic flow sheet of another optional embodiment of focus control method of the list display interface of a kind of intelligent television of the present invention, on embodiment illustrated in fig. 3 one basis, also comprise:
S306: according to holding the maximum of list items quantity in the total quantity of list items and interface visual windows, judge whether the serial number of target column list item meets the second prerequisite; If so, carry out next step.
Alternatively, the list items of list of hypotheses adds up to m, the serial number of target column list item is x, the maximum that can hold list items quantity in the visual windows of interface is n, the serial number that can hold in list items quantity in visual windows with the specify columns of a line or the nominated bank of same row is y, and satisfies condition: 2≤y≤n., in above-mentioned steps S306, judge whether the serial number of described target column list item meets the second prerequisite, be specially:
The serial number that judges target column list item is that whether x meets: 1≤x≤y-1; Or m-(n-y)≤x≤m.
S307: will show that Focal Point Shift is to the physical location of target column list item in visual windows.
