Detailed description of the invention
Technical scheme in the embodiment of the present invention is carried out clear, complete description by the accompanying drawing below in conjunction with the present invention, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment of present invention China, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention。
A kind of cursor control method based on touch pad of the embodiment of the present invention, control, by touch pad, the electronic equipment that the cursor of display screen moves and positions suitable in PC, panel computer, mobile phone, PDA (PersonalDigitalAssistant, palm PC), electronic reader, notebook computer, intelligent television, car-mounted terminal etc.。
Below in conjunction with accompanying drawing 1-accompanying drawing 2, the cursor control method based on touch pad that the embodiment of the present invention is provided describes in detail。
Referring to the flow chart that Fig. 1, Fig. 1 are the first embodiments of a kind of cursor control method based on touch pad of the present invention, the method specifically includes following steps S1-S4:
Step S1, gathers the touch sensible data on touch pad, described touch sensible data is stored in pre-assigned buffer memory。Wherein, described touch sensible data are touch sensible event position coordinates in the XY coordinate system of touch pad。
Touch sensible event includes the event of user's finger touch pad or user uses the device of induction pen etc to click the event of touch pad, and namely the touch sensible data gathered on touch pad gather the position coordinates on the touch pad corresponding to touch event。
Preferably, the embodiment of the present invention periodically gathers the touch sensible data on touch pad by the interval preset, and described interval may be set to 8MS, 10MS or 16MS。The acquisition time interval arranged is more big, and the time delay moved by the cursor in touch pad control display screen is more big, the sensitivity decrease that cursor moves for a user, it is simple to user accurately controls light target and moves。
Step S2, confirms that described buffer memory is full, then calculate current cursor reference position coordinate according to whole touch sensible data of storage in described buffer memory。
Buffer memory is one piece of memory chip on hard disk controller, has the access rate being exceedingly fast, and it is the buffer between hard drive internal storage and extraneous interface。According to data storage method therein can be categorized as that last in, first out type and first-in first-out type。Owing to be tracked identification to what user's finger or induction pen moved, it is thus desirable at least gather 3 touch sensible data, and according to this touch sensible data of the 1st to the 3rd or more than three are stored in the buffer memory of pre-assigned FIFO, therefore pre-assigned buffer memory described in this enforcement is the buffer memory that capacity at least can store the first in first out of 3 touch sensible data, and described buffer memory capacity is more big, storable touch sensible data are more many, the quantity then participating in calculating the touch sensible data of current cursor reference position coordinate is more big, the cursor reference position coordinate drawn is more accurate, thus can reduce the jitter phenomenon that cursor moves；But along with the increase of buffer memory capacity, the time delay also resulting in cursor reaction strengthens。User can previously according to being actually needed the touch sensible data that the suitable cache size of distribution collects with storage。
It is preferred that in the present embodiment, be designated as (curX, curY) by current cursor reference position coordinate, described calculates current cursor reference position coordinate according to whole touch sensible data of storage in described buffer memory, particularly as follows:
CurX=(X0+X1 ...+Xn)/DB；
CurY=(Y0+Y1 ...+Yn)/DB；
Wherein, the X value of the touch sensible event of each touch sensible data that X0, X1 ..., Xn are respectively stored in described buffer memory position coordinates in touch pad XY coordinate system；The Y value of the touch sensible event of each touch sensible data that Y0, Y1 ..., Yn are respectively stored in described buffer memory position coordinates in touch pad XY coordinate system；N is the amount of capacity of described buffer memory, and this value is be more than or equal to 3, further demonstrate that pre-assigned buffer memory storable touch sensible data are more many, namely n is more big, participate in touch sensible data more many of conversion, the cursor position coordinate that corresponding conversion goes out is more stable, thus can reduce the jitter phenomenon that cursor moves。DB is the default radix realizing regulating the DPI value of the mouse function of touch pad；CurX is the X value of the current cursor reference position coordinate drawn；CurY is the Y value of the current cursor reference position coordinate drawn。
According to current cursor reference position coordinate and the last cursor reference position coordinate calculated, step S3, show that cursor moves side-play amount。
As from the foregoing, the embodiment of the present invention uses variable curX to preserve the X value of the current cursor reference position coordinate calculated, variable curY is used to preserve the Y value of the current cursor reference position coordinate calculated, use variable lastX to preserve the X value of the current cursor reference position coordinate that the last time calculates, use variable lastY to preserve the Y value of the current cursor reference position coordinate that the last time calculates。
It is preferred that according to current cursor reference position coordinate and the last cursor reference position coordinate calculated, the present embodiment show that cursor moves side-play amount, it is specifically divided into following 3 kinds of situations。
Situation one, if the coordinate system of system is contrary with the XY coordinate system of touch pad, then:
CursorX=curX lastX；
CursorY=curY lastY；
Wherein, lastX, lastY respectively last curX, curY calculated；The cursor that cursorX, cursorY respectively draw moves the X side-play amount of side-play amount, Y side-play amount。
Situation two, if the coordinate system of system is identical with the XY coordinate system seat of touch pad, but XY is in opposite direction, then:
CursorX=lastX-curX；
CursorY=lastY curY；
Wherein, lastX, lastY respectively last curX, curY calculated；The cursor that cursorX, cursorY respectively draw moves the X side-play amount of side-play amount, Y side-play amount。
Situation three, if the coordinate system of system is identical with the XY coordinate system of touch pad, X, Y-direction is identical, then:
CursorX=curX lastX；
CursorY=curY lastY；
Wherein, lastX, lastY respectively last curX, curY calculated；The cursor that cursorX, cursorY respectively draw moves the X side-play amount of side-play amount, Y side-play amount。
Visible, described radix DB is more little, and corresponding DPI value is more big, and user's finger only need to move a small distance and the movement of controllable cursor bigger side-play amount on a display screen on a touchpad；Radix DB is more big, and corresponding DPI value is more little, and comparatively speaking, user's finger moves formed objects distance on a touchpad, and the side-play amount that corresponding cursor moves on a display screen diminishes。The value of concrete radix DB can set according to practical situation, and then facilitates user to pass through the cursor in the various sizes of display screen of touchpad operation。
And, according to current cursor reference position coordinate and on after the cursor position coordinate that once calculates show that cursor moves side-play amount, also need to update the cursor reference position coordinate that the described last time calculates, particularly as follows: be assigned to variable lastX, lastY by the value of described variable curX, curY。
Step S4, uses the cursor that described cursor moves in side-play amount control display screen to move。Specifically, upload described cursor to move side-play amount to system, the cursor that system moves in side-play amount control display screen according to described cursor moves。
In the present embodiment, when described buffer memory is filled with, the whole touch sensible data wherein stored carrying out equalization process, then the radix divided by default reaction DPI value, the current cursor reference position coordinate that can make to calculate is more accurate, it is prevented that jitter phenomenon。。
It is preferred that described interval is set to 8MS by the embodiment of the present invention。Further, as shown in Figure 2, it may be preferable that the capacity of buffer memory described in the present embodiment is for can store 3 touch sensible data, namely when the touch sensible data storing front 3 8MS in described buffer memory, after being labeled as data 0,1,2 according to this；When next acquisition time arrives, when namely next 8MS arrives, first removal data 0, then the touch sensible data newly gathered are stored in, it is labeled as data 3；In like manner, when next one 8MS arrives, first removal data 1, the new touch sensible data gathered of restoring, it is labeled as data 4, by that analogy。
The cursor control method based on touch pad of the above embodiment of the present invention, can pass through to regulate DB worth go out different touch pad DPI value, below act instantiation is explained。
Assuming that the coordinate system of device systems is identical with the XY coordinate system of touch pad, X, Y-direction is identical；Described buffer memory can store 3 touch sensible data, and namely buffer memory is the buffer memory of the touch sensible data that can store 3*8MS, and position coordinates corresponding to described touch sensible data is designated as (X0, Y0), (X1, and (X2, Y2), and have Y1):
X0=10, X1=30, X2=20；
Y0=0, Y1=20, Y2=30；
The cursor reference position coordinate that in system, the last time of storage calculates is: lastX=10, lastY=12；
As default radix DB=1, show that current cursor side-play amount is calculated as follows:
CurX=(X0+X1+X3)/DB=(10+30+20)/1=60；
CurY=(Y0+Y1+Y3)/DB=(0+20+30)/1=50；
CursorX=curX lastX=60 10=50；
CursorY=curY lastY=50 12=38；
In the display screen that the touchpad operation of visible active user is corresponding, cursor moves side-play amount is X-direction 50, Y-direction 38。
When presetting described radix DB=2, cursor side-play amount is calculated as:
CurX=(X0+X1+X3)/DB=(10+30+20)/2=30；
CurY=(Y0+Y1+Y3)/DB=(0+20+30)/2=25；
CursorX=curX lastX=30 10=20；
CursorY=curY lastY=25 12=13；
The side-play amount that in the display screen that the same touchpad operation of visible active user is corresponding, cursor moves is X-direction 20, Y-direction 13。The side-play amount that cursor during relative to radix DB=1 moves diminishes。User provides the value regulating radix DB, it is achieved regulate the purpose of the DPI value of touch pad。
By the cursor control method based on touch pad of above-described embodiment, calculate the position coordinates of current cursor according to the multiple touch sensible data on touch pad, and then draw light target side-play amount in the display screen of correspondence so that cursor mobile accuracy is higher, linear track is more stable, rounder and more smooth；Meanwhile, facilitate user to adjust the DPI value of mouse function of touch pad flexibly according to the size of display screen and individual's use habit, provide users with the convenient。
