Embodiment
See also Fig. 1, it is the functional block diagram according to the contactor control device 1 of a preferred embodiment of the present invention.Contactor control device 1 comprises panel module 12 and handles module 14.Processing module 14 to determine button size, produces dummy keyboard based on this button size based on the position that is implemented on a plurality of touch points on the panel module 12 again.By this, the finger tip distance that the press button gap of this dummy keyboard can the person of being used makes the user to see through this dummy keyboard like a cork and carry out input operation.
Further; In present embodiment, panel module 12 comprises touch module 122 and shows module 124, and touch module 122 has touch surface 1222; Touch for the user; Wherein touch module 122 can be embedded (in-cell) or external hanging type (on-cell) structure and the touch-control display panel structure that can form with showing module 124, but the present invention is as limit, and for example both divide and are arranged.When the user desires with keyboard input pattern entering operation, generally speaking, the user will touch touch surface 1222 and produce a plurality of touch points with the both hands finger naturally.At this moment, the position of each touch point is the key position of user's expection.Because the most button size of general custom keyboard is all suitable, so the range averaging value of position that is able to these a plurality of touch points is as the basis of the button size of the dummy keyboard of judging the desire generation.
What remark additionally is; In practical application, if the user is positioned over 1222 last times of touch surface simultaneously with both hands, then these a plurality of touch points can be divided into two groups; Distance between the touch-control point group is not listed aforementioned mean value in and is judged; And calculating of afore-mentioned distance mean value serves as to calculate the basis with the distance between adjacent touch point directly, but the present invention also is able to more complicated algorithm definition afore-mentioned distance mean value not as limit in practical application.In addition, in each group touch point, possibly also can be further divided into two parts: on behalf of thumb, another part, a part represent all the other four fingers.At this moment, the calculating of afore-mentioned distance mean value should serve as to calculate the basis with the touch point position of representing four fingers; Again, according to custom, thumb is usually located at the position of blank key, so the distance between thumb and all the other four fingers also can be used as the basis of this button size of decision.For example suppose that four refer to that orientation is a horizontal direction, then go out the horizontal direction size of this button size, and the distance between thumb and all the other four fingers is as the vertical direction size of this button size of twice with the touch point determining positions of representing four fingers; In other words, this button size possibly be rectangular size.Supplementary notes is again; Every user gesture of typewriting is not quite similar; So also maybe be only each four refers to or the finger of smaller amounts carries out the keyboard input operation with both hands, yet the decision of its button size is still roughly the same with above stated specification, the related description of its determining method can be consulted back literary composition explanation.
Afterwards, handle module 14 and can produce dummy keyboard 126 according to the corresponding touch surface 1222 of this button size.See also Fig. 2, it is the synoptic diagram that contactor control device 1 shows dummy keyboard 126.In present embodiment; Because panel module 12 has touch-control and Presentation Function concurrently; Drive and show that modules 124 show dummy keyboards 126 so handle module 14, it be reference point that its display position one of is able in the touch point (being illustrated in Fig. 2 with dashed circle), and dummy keyboard 126 is launched demonstrations; Being reference point with the touch point of representing left index finger for example, is that reference key launches dummy keyboard 126 with " F " key; But in practical application, with other buttons be reference key also can, or with other touch points be reference point also can, the present invention is not all as limit.Supplementary notes be, because of in present embodiment, dummy keyboard 126 can be by showing that module 124 shows, so the user certainly can be through the position of visual determination dummy keyboard 126, the generation position of dummy keyboard 126 gets not position with touch point as benchmark; Otherwise; When contactor control device of the present invention in a certain embodiment, when not having Presentation Function, the Trackpad in the structural design of touch-control, display separation for example; Then handling module should be the basis that produces the position of dummy keyboard with the position of touch point, carries out touch-typing operation in order to the user.Certainly, in the contactor control device with Presentation Function 1, also do not show dummy keyboard.
In addition; Owing to have the panel module 12 of Presentation Function the demand that shows other images is simultaneously also arranged; So under common situation, the part of the display screen 128 of panel module 12 is used to show dummy keyboard 126, other parts then can be used for showing other images of application; If dummy keyboard 126 shows that with the mode of watermark the sharpness of the former show image of unlikely influence then also can overlappingly show, or only be aided with when user's finger touches touch surface 1222, the beginning shows dummy keyboard 126.Supplementary notes is again, and in present embodiment, the scope of display screen 128 also is the scope of touch surface 1222, but the present invention is not as limit.In addition, the dummy keyboard of generation does not exceed with the general standard keyboard, other users from the keyboard configuration ordered also can, even can the general standard keyboard be divided into two parts, separate configuration; The present invention is not as limit.
See also Fig. 3, it is the process flow diagram according to the method for the formation dummy keyboard of a preferred embodiment of the present invention.For ease of explanation, be example directly with aforementioned contactor control device 1, about related description such as its structure, functions, see also preamble, give unnecessary details no longer one by one.As shown in Figure 3, this method at first makes contactor control device 1 get into the dummy keyboard input pattern, shown in step S100.For example triggering entity or virtual push button, or based on the setting of other applications, so that contactor control device 1 gets into this dummy keyboard input pattern; Again or judge the touch-control situation be implemented on touch surface 1222 whether to get into this dummy keyboard input pattern with decision.The latter's situation sees also Fig. 4.Fig. 4 is for being implemented on a plurality of touch point A1～A5 on the touch surface 1222, the synoptic diagram of B1～B5 according to an embodiment by panel module 12 sensings.Generally speaking, touch point A1～A5 can be caused by user's left hand, is thumb, forefinger, middle finger, the third finger and little finger of toe in regular turn; Touch point B1～B5 is then caused by the right hand, and preface is suitable also together.Wherein, represent the four touch point A2～A5, B2～B5 line that refer in a difference in height scope 1224, with ratio, touch point A2～A5, B2～B5 account for whole touch point A1～A5, B1～B5 80 percent; At this moment, handle module 14 and can trigger contactor control device 1 this dummy keyboard input pattern of entering.Supplementary notes be, the setting of aforementioned difference in height scope 1224 can be set in advance, or the single-point touch point that on touch surface 1222, induces with touch point footpath serves as that the basis determines, for example with difference in height scope 1224 set become twice average touch point directly; Again; Every user's operation keyboard custom is not quite similar; For example little finger of toe all lifts except that the needs pressing keys, so only touch point A3～A5, B3～B5 (when thumb is also touched) quilt cover template die group 12 sensings at the beginning account for whole touch point A1～A5, B1～B5 75 percent.Supplementary notes is again, and aforementioned touch point A1～A5, B1～B5 can be divided into two groups, and in practical application, the judgement of this dummy keyboard input pattern of aforementioned entering can be only be used as judgement basis by a group wherein; This with the situation of difference of height or mutual crooked placement, has its real benefit to the user of one hand typewriting or both hands.
Shown in the process flow diagram of Fig. 3, this method is handled module 14 based on being implemented on a plurality of touch point A1～A5 on the touch surface 1222, the determining positions button size of B1～B5, shown in step S110 in then utilizing behind the step S100.In step S110, this method at first determines the position of touch point A1～A5, B1～B5, then calculates the range averaging value of the position of touch point A1～A5, B1～B5, again based on this this button size of range averaging value decision.Afore-mentioned distance mean value can (like Fig. 4 middle distance d1～d3), on average obtain again, but the present invention tries to achieve this range averaging value with more complicated algorithm and also can not as limit in practical application by the distance of calculating adjacent touch point A2～A5, B2～B5.Again; In practical application, also can simplify the deciding step of this button size, for example only select wherein two touch points (for example represent touch point A2, the A3 of forefinger and middle finger or represent middle finger and nameless touch point A3, A4); And go out its distance with its position calculation, as this button size.
What remark additionally is that because thumb and other four fingers spacings are far away, it crosses over not only button, so in the calculating of aforementioned this range averaging value, do not consider usually.Only thumb and forefinger spacing are generally the distance (like Fig. 4 middle distance d4) of two buttons, so also can be used as the decision basis of this button size; At this moment; This button size can comprise horizontal direction size and vertical direction size; Wherein the horizontal direction size serves as to calculate the basis with the touch point A2～A5 that represents four fingers, the position of B2～B5, and the vertical direction size serves as to calculate the basis with the touch point A1～A2 that represents thumb and forefinger, the position of B1～B2.In other words, this button size is not exceeded with square.
See also Fig. 5, it is for handling the synoptic diagram that module 14 corresponding touch surface 1222 produce dummy keyboard 126, and wherein touch point A1～A5, B1～B5 represent with dashed circle.According to the process flow diagram of Fig. 3, this method is then utilized behind step S110 and is handled module 14 based on this button size, and corresponding touch surface 1222 produces dummy keyboard 126, shown in step S120.In practical application, this method one of can be selected earlier among touch point A1～A5, the B1～B5 as a reference point; In present embodiment, with touch point A2 (representative left index finger) as this reference point.Then, this method is with " F " key of the corresponding dummy keyboard 126 of this reference point, to confirm the position of dummy keyboard 126 relative touch surface 1222.But in practical application, also must select other touch points, for example touch point A3～A5, B2～B4, " D " key of corresponding dummy keyboard 126, " S " key, " A " key, " J " key, " K " key and " L " key as reference point; But the present invention is not as limit.In addition, in present embodiment,, drive demonstration module 124 demonstration dummy keyboards 126 so handle module 14, shown in step S130 among Fig. 3 because of panel module 12 also has Presentation Function; But in practical application, the present invention is not exceeded to demonstrate dummy keyboard 126.Again, aforementioned demonstration is not also to show that whole dummy keyboard 126 exceeds.The related description that the explanation of other relevant dummy keyboards 126 can be consulted aforementioned contactor control device 1 repeats no more.
In addition, though aforementioned be example to produce single, whole dummy keyboard, the present invention is not as limit.See also Fig. 6, it is for handling the synoptic diagram that module 14 corresponding touch surface 1222 produce dummy keyboard 127 according to another embodiment.In present embodiment; Dummy keyboard 127 is made up of two divided portion keyboard 127a, 127b; Corresponding respectively two crowds of touch point A1～A5, B1～B5; Part keyboard 127a is that the relative touch surface 1222 of reference point produces with touch point A2 and shows that part keyboard 127b is that the relative touch surface 1222 of reference point produces and demonstration with touch point B2 (representing right hand forefinger) then.Wherein, because of based on user's gesture custom, part keyboard 127a, 127b are mutual crooked configuration; In practical application, part keyboard 127a, 127b also must separate suitable distance configuration, for example are disposed at the both sides of the display screen of broad.
What remark additionally is that previous embodiment is an example with the contactor control device that has Presentation Function simultaneously, for example general touch-control display screen; But the present invention is not as limit.In other words, only have a device of touch controllable function, for example Trackpad also has of the present invention being suitable for.In addition, dummy keyboard of the present invention does not exceed with the general standard keyboard, and for example numeric keypad or other users also can from the keyboard of ordering.
Compared to prior art; Utilize method of the present invention can be on contactor control device of the present invention based on the information of user's actual touch spots and produce dummy keyboard; So the key configurations of this dummy keyboard can meet user's operating habit, make the user to implement the typewriting operation with the input attitude of nature, even touch-typing operation; This ergonomic and increase operation convenience solve all inconvenience that only can show the dummy keyboard of fixed measure in the prior art and cause the input of user's button.
