Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1 to Fig. 2, the present invention is a kind of input switched system based on multi-point touch plate,
it matches with multi-point touch plate 4 and display screen 5, comprising:
touch signal receiver module 1, signal analyse block 2, mode selection module 3;
described touch signal receiver module 1 is connected with multi-point touch plate 4, for receiving the contact signal in multi-point touch plate 4;
described signal analyse block 2 is connected with touch signal receiver module 1, for the contact signal that touch signal receiver module 1 is sent, analyze, judge and in this contact signal, whether have multiple spot trigger pip, if there is multiple spot trigger pip,, according to the activation bit in this multiple spot trigger pip, the subelement in mode selection module 3 is selected to drive; For example, four indications of take are hit as activation bit, and signal analyse block 2 receives after the signal that four indications hit, and successively mouse unit, picture unit, word input block is driven to switching; Again for example, not pin the activation bit that is operating as mouse unit of four jiaos of touch pads, take and singly refer to pin the activation bit that the upper left corner of touch pad is picture unit, take and singly refer to pin the activation bit that the lower left corner of touch pad is word input block, by inputting different click information, can complete independently calling mouse unit, picture unit, word input block; It makes the switching of input pattern very convenient, is applicable to being applied to the applied environment of various complexity, as picture carried out to the occasions such as label character in the limit of drawing: limit.
subelement in described mode selection module 3 comprises: mouse unit 31 or picture unit 32;
described mouse unit 31 is connected with touch signal receiver module 1, for setting up the coordinate mapping relations between touch pad and display screen, receives contact signal and according to the coordinate information in contact signal, on the coordinate position of display screen 5 correspondences, cursor is shown;
described picture unit 32 is connected with touch signal receiver module 1, for generate drawing board on display screen 5, and set up the coordinate mapping relations between touch pad and drawing board, receive contact signal and according to the coordinate information in contact signal, on drawing board, draw.
in the present invention, the click mode of described multiple point touching signal is only an embodiment in the present embodiment, does not do concrete restriction herein.
further, the subelement in described mode selection module 3 also comprises: word input block 33 and lteral data storehouse;
described word input block 33 is connected with touch signal receiver module 1, for generate Input Method Editor on display screen 5, and set up the coordinate mapping relations between the input frame in touch pad and Input Method Editor, receive contact signal and according to the coordinate information in contact signal, mate with lteral data storehouse, from lteral data storehouse, transfer candidate character, and input by the word of having chosen to candidate character.As a kind of embodiment, user can pin the lower left corner of touch pad, and carries out handwriting input in all the other places of touch pad, and when finger leaves the lower left corner, candidate's font is chosen.
further, in described word input block, be also provided with input function controller, described input function controller is for judging whether the multiple spot trigger pip that touch signal receiver module 1 sends contains function information, if contain function information, extract this function information, and according to this function information, coordinate information confirmed or cancelled, it can also be realized the word of whole input is removed, or the stroke of last input is returned; As the function information of confirming input is that two indication hit, the function information of cancelling input is that three indications are hit, user is when word input block is enabled, and user carries out handwriting input by the action that singly refers on touch pad to word, and give directions to hit to complete by two fingers or three, confirms and cancels.
further, in described picture unit 32, be also provided with picture function control device, described picture function control device is for judging whether the multiple spot trigger pip that touch signal receiver module 1 sends contains function information, if contain function information, extract this function information, and according to this function information to coordinate information being confirmed or being cancelled, or drawing board is carried out to whole convergent-divergent, its operating process and word input block are basic identical, and it can also realize the whole convergent-divergent to drawing board by multiconductor signal, and it is realized and confirms the function information identical with word input block with cancelling all employings.As a kind of embodiment, when picture unit 32 is driven, user can pin the lower left corner of touch pad, and draws in all the other places of touch pad, and when finger leaves the lower left corner, the movement while paintbrush being carried out to non-drawing.
further, the present invention also comprises: MIM message input module 6, described MIM message input module is connected with signal analyse block 2, mode selection module 3, for activation bit and function information are set.It makes user according to the custom of oneself, to preset the input rule of each activation bit and function information.
further, on described touch pad, there are at least two default control regions, described signal analyse block also comprises: control detecting signal unit, the contact signal that described control detecting signal unit produces for detection of the default control regions whether having in contact signal by touch pad.
further, the default control regions of described touch pad is four angles on touch pad; By presetting of user, make user to realize the function that it presets by touching one jiao of any touch pad optional position with touch pad, as: pattern switching, convergent-divergent, confirmation, cancellation etc.
please refer to Fig. 3, the mode of switching in pattern of the present invention has two kinds, the first, and by three activation bits, the input pattern that drive is corresponding with activation bit, concrete pattern handoff procedure is:
the multiple spot trigger pip that input contains activation bit;
this activation bit is judged, according to the content of this activation bit, selectivity is to mouse unit or picture unit or word input block transmission driving order again;
after receiving the driving order of word input block, judge whether to exist word input block, as existed, drive word input block, if do not existed, do not carry out any action.
please refer to Fig. 4, the second pattern handoff procedure of the present invention is: by an activation bit, select successively input pattern; Its specific works process is:
the multiple spot trigger pip that input contains activation bit;
judge whether to exist word input block, as existed, between mouse unit, picture unit, word input block, switch successively, if do not existed, at mouse unit, picture, between unit, switch successively.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
