Description
Technical field
The present invention relates to a kind of touch-control system and touch operation method thereof and computer system, particularly relate to a kind of touch-control system and touch operation method and computer system with highly compatible.
Background technology
Graphical user interface (Graphical User Interface) is a kind of computer operation interface that is simple and easy to usefulness, it is display window, icon, a button figures on picture, make the user to select, to carry out the running of various objectives by an indicator device.In the prior art, common indicator device just belongs to Trackpad and is most commonly used in the computer system except that mouse, mobile computer particularly, and main cause is that Trackpad can be fixedly set in the mobile computer, thereby helps portable realization.And in the employed touch technology of Trackpad, the capacitive touch control techniques because of have stable performance, sensitivity is good and advantage such as durable, has become one of at present most popular touch technology.
In general, the capacitive touch control techniques mainly be by human body when touch point on the contact panel contacts, because of static changes in conjunction with the inductance capacitance that is produced, judge the touch-control incident, in other words, promptly utilize the capacitance characteristic difference of a certain touch point of human body touch front and back, realize touch controllable function.Please refer to Fig. 1, Fig. 1 is the synoptic diagram of an existing projected capacitive induction installation 10.Electric capacity projected capacitive induction installation 10 includes inductance capacitance serial X
1～X
mWith Y
1～Y
n, each inductance capacitance serial is the one-dimentional structure that is concatenated into by a plurality of inductance capacitance.Existing touch control detection mode has judged whether that for detecting the capacitance of each inductance capacitance serial the touch-control incident takes place.Suppose inductance capacitance serial X
1A inductance capacitance arranged, and the capacitance of each inductance capacitance is C, then under the normal condition, and inductance capacitance serial X
1Capacitance be aC.If human body (for example finger) touches inductance capacitance serial X
1On a certain inductance capacitance the time capacitance change be Δ C.If detect inductance capacitance serial X
1Capacitance when being (aC+ Δ C), represent that promptly present finger just is being contacted with inductance capacitance serial X
1On the somewhere.As shown in Figure 1, touch touch point A (i.e. (X in finger
3, Y
3) the coordinate place) time, inductance capacitance serial X
3And Y
3Sense capacitance variations simultaneously, and judge that touch-control sensing point is at (X
3, Y
3) locate.
Yet, during at the situation of multi-point touch, the situation that projected capacitive induction installation 10 may be judged by accident.For instance, please refer to Fig. 2, Fig. 2 is the multi-point touch synoptic diagram of projected capacitive induction installation 10.As shown in Figure 2, owing to have two fingers to touch projected capacitive induction installation 10 simultaneously, inductance capacitance serial X
3, X
M-1, Y
3, Y
N-1Can sense capacitance variations simultaneously, thereby will judge to become at (X
3, Y
3), (X
3, Y
N-1), (X
M-1, Y
3), (X
M-1, Y
N-1) located the touch-control incident and take place.But, in fact, (X is only arranged
3, Y
3) and (X
M-1, Y
N-1) be true touch point, and (X
3, Y
N-1), (X
M-1, Y
3) be not true touch point.In the case, the result that projected capacitive induction installation 10 makes a mistake and judges, and make testing result report two non-true touch points by mistake, just caused the situation of so-called ghost key (ghost key).Therefore, when the situation of multi-point touch, the confluce that only can learn which inductance capacitance serial has the touch-control incident and takes place, and can't orient true touch point really.At the operation of multi-point touch, existing Trackpad is to use exclusive driver in absolute mode (Absolute Mode) operation down, judges by exclusive driver, to finish user's instruction, is described in detail as follows.
Please refer to Fig. 3, Fig. 3 illustrates the situation that Trackpad operates with relative pattern and absolute mode respectively in computer system.Relative pattern (Relative Mode) is represented in the left side of Fig. 3, and absolute mode is represented on the right side.In simple terms, under relative pattern, Trackpad be with responded to press situation and carry out simple displacement and judge after, send institute's judged result to internal driving program and carry out, to realize user's instruction; And under absolute mode, Trackpad is the situation that presses that will be responded to, and all sends the operation of exclusive driver to, is judged and is carried out pairing user's instruction by exclusive driver.Specifically, under relative pattern, Trackpad calculates touch information through displacement after, produce the sensor signal of 4 byte packet, by the embedded controller transmission, with the difference of touch information such as relative position and button whether activation (X, Y, Z, B) repayment give the internal driving program of system, make system carry out user's instruction according to this.Therefore, under the situation of multi-point touch,, give internal driving program so can't repay difference, and can't carry out user's instruction because Trackpad can't be judged true touch point.And under absolute mode, Trackpad be according to as finger (or other object) touch point position, button situation, touch informations (X, Y, B, M, W) such as multi-point touch, power whether, produce the sensor signal of a plurality of 6 byte packet, by the embedded controller transmission, the driver of exclusive this Trackpad in the system is given in repayment, the displacement (comprising data such as distance, scroll bar) of calculating touch point according to this by system and exclusive driver, and carry out user's instruction.Therefore, when the situation of multi-point touch, Trackpad is repaid the sensed data that every bit determines to driver exclusive in the system by the embedded controller transmission, after it judges pairing user's instruction, allows system according to user's instruction manipulation.Therefore, under absolute mode, Trackpad can be judged by exclusive driver, to reach the operation of multi-point touch.
Yet, its the exclusive driver operation of must arranging in pairs or groups of some Trackpad or touch control induction device, otherwise can't realize some basic or specific user's instruction, cause the range limited of use, when exclusive driver promptly is not installed, can't use this Trackpad or touch control induction device in system.For instance, Fig. 4 is the operation chart of an existing Trackpad 40.Trackpad 40 below the right and left dotted portion key zone Area_L and Area_R bottom keep the left button Pad_L and the right button Pad_R of general Trackpad respectively, can be in receiving activation, to reach the further purpose of reduced volume greater than the external force of a predeterminable level.In the case, push the A point when user's a finger and make left button Pad_L activation, when another finger moves to the C point by the B point (drag kick), under relative pattern, sense 2 touch-controls of A point and B to C point simultaneously owing to Trackpad, and can't judge true touch point, give internal driving program so can't repay difference, to such an extent as to can't carry out user's instruction; And under absolute mode, Trackpad repays the sensed data of A point and B to C point to driver exclusive in the system, after it judges pairing user's instruction, allows system according to user's instruction manipulation.Hence one can see that, and Trackpad 40 its exclusive driver of must arranging in pairs or groups is operated under absolute mode, otherwise the operation that basic collocation button uses all can't be carried out.In other words, Trackpad 40 can't use internal driving program operating under the pattern relatively.
Therefore, at this new-type Trackpad, its exclusive driver if the operating system in its operated computer system is not arranged in pairs or groups, the operation that then basic collocation button uses all can't be carried out.In view of this, prior art has improved necessity in fact.
