Replace the modifier keys (modifier key) such as key (Alt Key) to be positioned in modifier keys region 306, and the second operation
Region is the subregion of the first operating area.Wherein, detect corresponding to modifying when resistive switch layer 206
In key range 306 during the pressing operation of arbitrary modifier keys, control unit 102 makes capacitive sensing layer 204 only detect
Survey the modifier keys region 306 operating gesture with exterior domain to produce gesture path, such as: only detecting the second behaviour
Make region 304.Otherwise, when resistive switch layer 206 does not detects the pressing operation corresponding to arbitrary modifier keys,
Control unit 102 makes capacitive sensing layer 204 detecting contain the operating gesture in whole first operating area 302
To produce gesture path.Consequently, it is possible to when user be intended to by according in the first operating space 302 modifier keys (as
Ctrl or shift key) collocation operating gesture (or with towing mode frame choosing) main frame 106 clicking multiple
When file is to carry out replicating operation, control unit 102 makes 204 detecting of capacitive sensing layer be positioned at the second operation
Operating gesture in region 304, so time in modifier keys region 306, only can have button operation function,
Modifier keys region 306 can't produce any gesture path signal simultaneously.Therefore the present embodiment can be effectively
Reduction program judges the degree of difficulty that modifier keys operates.
Furtherly, in the present embodiment, detect corresponding to modifier keys region 306 when resistive switch layer 206
In the pressing operation of arbitrary modifier keys time, control unit 102 make (1) resistive switch layer 206 still detect be positioned at whole
Pressing operation in individual first operating area 302 is to produce press signal, and makes (2) capacitive sensing layer only detect
Survey the modifier keys region 306 operating gesture with exterior domain to produce gesture path, such as: only detecting the second behaviour
Make region 304.Consequently, it is possible to program can clearly according to corresponding to the press signal in the first operating area with
And corresponding to the gesture path in the second operating area, it is judged that the combination operation that collocation modifier keys is carried out.
Refer to Fig. 3, it illustrates the first operating area defined in key area layer 202 and the second operating space
One of territory example.As it is shown on figure 3, the first operating area 302 is the second operating area 304 and modifier keys region
The summation of 306, that is the second operating area 304 is after the first operating area 302 gets rid of modifier keys region 306

304 comprise 26 English alphabet keys and 10 numerical keys, and modifier keys region 306 is for extending the second operating space
The L-type region of left, territory 304 and lower section, this L-type region comprises modifier keys, such as: shift key (Shift
Key), the key such as operating key (Ctrl Key) and replacement key (Alt Key).
Refer to Fig. 4, it illustrates the block diagram of control unit 102.As shown in Figure 4, control unit 102 is wrapped
Include capacitive sensing layer and control module 402 and resistive switch layer control module 404.Capacitive sensing layer controls module
402 in order to control the electrode of capacitive sensing layer 204.Resistive switch layer controls module 404 in order to open according to resistance
Close the pressing operation that layer 206 is detected, it is provided that pressing position signal to capacitive sensing layer controls module 404.
Wherein, when control unit 102 finds that this pressing position signal is positioned in modifier keys region 306, this electric capacity
Inductive layer control module 402 selectively closes off according to pressing position signal and corresponds to modifier keys region 306 (bag
Containing being pressed modifier keys position corresponding to this) partial row electrode and part row electrode, and remaining still starting
Another part row electrode of state and another part row electrode are corresponding to the second operating area 304.
Such as, detect corresponding to the modifier keys (lower left corner in such as the keyboard layout of Fig. 3 when resistive switch layer 206
Ctrl) pressing operation time, the position that control unit 102 can be detected according to this pressing operation,
Close the partial row electrode corresponding to this modifier keys position and part row electrode, to stop scanning corresponding to repairing
The operating gesture of decorations key range 306 (comprise and be pressed modifier keys position corresponding to this).Consequently, it is possible to electric capacity
Inductive layer 204 will only can detect on the region (such as the second operating area 304) not being stopped scanning
Operating gesture, produces corresponding gesture path.
In another example, when this resistive switch layer 206 detects the pressing operation corresponding to modifier keys,
The position that control unit 102 is detected according to this pressing operation, closes the row corresponding to this modifier keys position
Electrode and row electrode.As an example it is assumed that by the position of a certain modifier keys corresponding to row electrode Y3～Y6With
And row electrode X3～X6, (this when this resistive switch layer 206 detects the pressing operation corresponding to this modifier keys
Pressing operation is such as corresponding to row electrode Y3～Y6And row electrode X3～X6Position), control unit 102
The position being detected according to this pressing operation, closes row electrode (the such as row electricity corresponding to this modifier keys position
Pole Y3～Y6) and row electrode (such as row electrode X3～X6)。
Briefly, control unit 102 can correspond to modifier keys region 306 by closing capacitive sensing layer 204
Row electrode and row electrode, so to reach only to detect the operating gesture on the second operating area 304.
Additionally, in the present embodiment, when pressing operation terminates to exceed scheduled time slot (such as 1 millisecond (msec))
After, control unit 102 can reopen and corresponds to modifier keys region 306 pent row electrode and closed
The row electrode closed.Explain with Fig. 3, after pressing operation terminates to exceed scheduled time slot, control unit 102

The operating area surveying touch control gesture recovers to become the first bigger operating space again from the second less operating area 304
Territory 302.
Fig. 5 illustrates the flow chart of the method for operating of the peripheral device according to first embodiment of the invention.This operation
Method comprises the following steps.First, in step S502, whether resistive switch layer 206 is detected has corresponding to appointing
The pressing operation of what modifier keys.Then, in step S504, when resistive switch layer 206 detects corresponding to appointing
During the pressing operation of one modifier keys, control unit 102 is got rid of modifier keys region 306, is made capacitive sensing layer 204
Only detecting is positioned at the operating gesture of the second operating area 304 to produce gesture path.Or, in step S506,
When resistive switch layer 206 does not detects the pressing operation corresponding to any modifier keys, control unit 102 makes
Capacitive sensing layer 204 detecting is positioned at the operating gesture of complete first operating area 302 to produce gesture path.
More than Zong He, the peripheral device of the present embodiment can by selectively closing off the electrode of capacitive sensing layer,
Avoid producing gesture path and press signal in the modifier keys region being pressed simultaneously, and then be effectively reduced
Program judges the degree of difficulty that modifier keys operates.
Second embodiment
In this embodiment, when operation body 104 receive an external force and make resistive switch layer 206 detect by
Press operation, and capacitive sensing layer 204 therefore external force and when producing length less than the gesture path of length default value,
Control unit 102 exports this press signal to main frame 106, but control unit 102 will not be defeated to main frame 106
Go out this gesture path.Consequently, it is possible to when user's word to be carried out inputs, even if in the mistake of pressing keys
In journey, gesture path produces together with press signal, but because the gesture path less than certain length is left in the basket,
Therefore the present embodiment can be effectively prevented from word input point or cursor position is affected by gesture path.Additionally,
It is understood that the present embodiment can the other embodiments described in this specification be combined.
Refer to Fig. 6, it illustrates user and carries out operating and producing the hand of length S1 in key area layer 202
The schematic diagram of gesture track.As shown in Figure 6, a certain button in key arrangement 602 (representing with thick frame in figure)
It is pressed.Furtherly, when this external force pressed exceedes pressing critical value (being such as about or equal to the power of 60g),
Resistive switch layer 206 will be switched on and detects pressing operation.Now, because resistive switch layer 206 is detectd
The position of this pressing operation measured corresponds to this button, the pressing that main frame 106 is exported by control unit 102
Signal is the key corresponding to this button.As an example it is assumed that this button being pressed is letter key " W ",
Then control unit 102 exports the key corresponding to letter key " W " to main frame 106.
Owing to user is when pressing keys, thought key-press input point generally will not be fixed in the position of force
(such as, during pressing keys, finger may have the slip of trace), therefore often supervene gesture path.As
Shown in Fig. 6, this gesture is a length of length S1 of track in letter key " W ".When this length S1 is less than long
Degree default value, control unit 102 will not export this gesture path to main frame 106.Above-mentioned length acquiescence
Value range approximately from 3 millimeters (mm) to 5 millimeters, but it is understood that, length described in the present embodiment acquiescence
Value can adjust according to the size of button pattern or keycap area in keyboard layout, as long as such as less than three points
One of button pattern or the width of keycap area.
Refer to Fig. 7, it illustrates when resistive switch layer 206 is in a time point tRDetect pressing operation, control
Unit 102 processed will not export (or ignoring) and comprise from time point t main frame 106RThe period T started at is (i.e.
Time point tRTo time point t1Gesture path in).Consequently, it is possible to when user is with finger (or pointer)
When pressing keys, the position of key-press input point will not be produced unnecessary inclined by produced microdisplacement
Move.
In another example, control unit 102 is negligible comprises time point tRA period in gesture path.
For example, control unit 102 ignores time point tRA specific time period t beforep-tR(control unit 102
Still processing this gesture path, not yet this result exported main frame 106), and time point tRAfterwards
A specific time period tR-t1Produced gesture path.Even if consequently, it is possible to first touching during key press
Moved capacitive sensing layer 204 and produced unnecessary gesture path, control unit 102 still can be ignored with
The position avoiding key-press input point is affected.
Fig. 8 illustrates the flow chart of the method for operating of the peripheral device according to second embodiment of the invention.This operation
Method comprises the following steps.First, in step S802, resistive switch layer 206 in time point Tr detect by
Press operation, and capacitive sensing layer 204 detects user's gesture operation simultaneously.Then, in step S804,
Judge that whether gesture path length is less than default value.The most then start in preset period of time T from time point Tr,
Control unit can be output in preset period of time T to be detectd grasps the press signal arrived, but will not export and be detected
Gesture path (step S806).If it is not, then control unit 102 can export detected press signal and hand
Gesture track (step S808).In step S806, control unit can close capacitive sensing layer 204 by (1)
To stop detecting gesture path, or (2) ignore the gesture path detected from capacitive sensing layer 204, and two
Person all can reach to export the effect of gesture path.
More than Zong He, in this embodiment, if the gesture path supervened during user's pressing keys
Length is less than length default value, and control unit 102 is by key-press input to be carried out for judgement user rather than carries out class
It is similar to the gesture operation of mouse action, therefore this gesture path supervened can be ignored, to avoid key-press input
Point is affected by gesture path and is offset.
3rd embodiment
In this embodiment, when (a) gesture path length is more than default value, or (b) this gesture path is multiple spot
When contact (multi-touch) gesture alternative one is satisfied, if resistive switch layer 206 detects pressing simultaneously
Operation, then control unit 102 will not be to the press signal corresponding to main frame 106 output resistance switching layer 206.
Therefore, the present embodiment can carry out keyboard operation or gesture operation by distinguishing consumer effectively, when user is carried out
During gesture operation, can suitably ignore leading of the related produced unnecessary keyboard pressing operation of gesture operation
Communication number.Further, it is to be appreciated that the present embodiment can be described with this specification other embodiments
In conjunction with.
Refer to Fig. 9, it illustrates user and carries out operating and producing the hand of length S2 in key area layer 202
The schematic diagram of gesture track.As it is shown in figure 9, key arrangement 902 has a plurality of button, and gesture path
Length S2 is more than the space D of two adjacent key central points.With this space D (for example, 16mm to 20mm,
Preferably from about or equal to 18mm) by default as a example by value, owing to length S2 of gesture path is write from memory more than this
Recognizing value, control unit 102 will close resistive switch layer 206, make resistive switch layer 206 cannot produce pressing news
Number.In other words, in the case of the length of gesture path is more than default value, control unit 102 judges to use
Person imposes gesture operation (such as making the slip of long track with finger) rather than button operation, therefore closes electricity accordingly
Resistance switching layer 206 (interrupts the power supply supply of resistive switch layer 206, or control unit 102 ignores to come self-resistance
The signal of switching layer 206, and do not export corresponding character signal to main frame 106), to avoid because of gesture operation
And misoperation input button character.Above-mentioned default value is not limited with the spacing of two adjacent key central points,
Default value is also smaller than the spacing of two adjacent key central points.
Figure 10 illustrates the flow chart of the method for operating of the peripheral device according to third embodiment of the invention.This operation
Method comprises the following steps.First, in step S1002, resistive switch layer 206 detects pressing operation, and
Capacitive sensing layer 204 detects user's gesture operation simultaneously.Then, in step S1004, it is judged that gesture rail
Whether mark length is less than default value.The most then judge whether gesture path is single-contact gesture (step
S1006).If it is not, then control unit 102 can export gesture path, but press signal (step will not be exported
S1008).It addition, when the judged result of step S1006 is yes, then control unit 102 can export pressing news
Number, but gesture path (step S1010) will not be exported.When the judged result of step S1006 is no, the most then
Perform step S1008.Although it is understood that step S1004 and S1006 are successively held in Figure 10
OK, but in other example, the execution sequence of step S1004 and S1006 can exchange, or simultaneously
It is performed.In step S1008, control unit can close resistive switch layer 206 to stop detecting by (1)
Press signal, or (2) ignore the press signal detected from resistive switch layer 206, and both of which can reach
The effect of press signal will not be exported.Similarly, in step S1010, control unit can be closed by (1)
Capacitive sensing layer 204 is to stop detecting gesture path, or (2) are ignored and detected from capacitive sensing layer 204
Gesture path, both of which can reach to export the effect of gesture path.
Refer to Figure 11 A and Figure 11 B.Figure 11 A be illustrated in key area layer 202 impose amplification (zoom in),
Reduce the schematic diagram of the Multi-contact gesture of (zoom out) operating gesture.Figure 11 B is illustrated in key area layer
The schematic diagram of the 202 Multi-contact gestures imposing rotation (rotate) operating gesture.In the present embodiment, as long as
Control unit 102 judges that user imposes Multi-contact operating gesture as above in key area layer 202,
No matter whether the length of gesture path is more than default value, all can close resistive switch layer 206, to avoid pressing news
Number generation.So the present invention is not limited to this, except amplifying, reducing, the operating gesture such as rotation, corresponds to
The multipoint operation gesture of other touch controllable function is also applicable to the present embodiment.
More than Zong He, the peripheral device of the embodiment of the present invention by different Rule of judgment and can be controlled accordingly
System, is effectively prevented from when user imposes gesture operation (being similar to mouse action) and/or keyboard operation being caned
The misoperation that can produce, and the degree of difficulty that program judges can be reduced.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention.The present invention
Art has usually intellectual, without departing from the spirit and scope of the invention, each when making
