It is used for the anti-tactile of multi-point touch panel and by mistake authentication button the invention discloses a kind of, belongs to electronic instrumentation.The present invention prevents touching and missing authentication button by setting up on multi-point touch panel, the effect of particular conductivity pattern can be formed when pressing specific button on multi-point touch panel by being realized using the conductive fill block of button interior and the mutual specific distribution of insulation fill block, and then realize that the smart machine containing multi-point touch panel can carry out the function of false-touch prevention and anti-error certification by the button.
Description
Technical field
The present invention relates to one kind by setting up additional buttons on multi-point touch panel, to prevent the smart machine for possessing touch-screen, fortune
Row or implementation should not be by the separate procedures or specific function of false triggering.
Background technology
Because of the reason such as easy to operate, current touch screen has become most smart machines or the topmost I/O of intelligent terminal connects
Mouthful.But because the technical characterstic of touch-screen in itself, it inputs convenience and the proportional example increase of false touch problem.And in many fields
Close, process equipment, Medical Instruments and other security-related plant equipment are made in control in full needs strict false-touch prevention design.
In addition, being conducted interviews to the significant data file stored by smart machine with the data file for being related to individual privacy or property safety
During certification, convenience and security can also produce serious opposition.
For example, the entity button for replacing substantial amounts of numeral and function to input with one piece of touch-screen, can greatly simplify numerical control life
Produce control and the custom programming input complexity of process equipment.Different by being provided under different variable operator schemes is virtual
Button, can be achieved to operate the accurate start-up and shut-down control and midway reprogram of process.But if being pressed with virtual on touch-screen
Button substitutes the special buttons such as traditional equipment " emergency shutdown ", is just likely to cause false touch and cause a large amount of production accidents.One
Possible solution is that ejection confirms that dialog box is entered when setting operation person touches virtual emergency stop button in the controls
Row secondary-confirmation, but this considerably reduces the functional response speed of emergency stop button.Similarly, big portion is substituted with touch-screen
The entity button or knob of separating vehicles miscellaneous function are the developing direction of current new vehicle especially pure electric vehicle.But driving
Because touch-screen lacks tactile position feedback during sailing, sight is transferred to automobile middle control region from front windshield when driving
Touch-screen when finding virtual key, or when sight being concentrated on into front windshield and automobile miscellaneous function screen is clicked on carelessly ---
Such as false touch wrong button and mistakenly switch lamp light mode --- all easily cause traffic accident.Key function button is anti-error
The defect for the ability of touching so that it is not serious that the virtual key of touch-screen is only used for consequence during some false touches, or to the sound of function control
The occasion for answering rate request not high.
And such as, some programs or data file or text for being related to individual privacy or property safety are accessed on Intelligent mobile equipment
It is current often to be confirmed using touch gestures (such as nine grids unblock) or require input password confirming to confirm current operator when part is pressed from both sides
Whether operating right is possessed, the convenience that this is operated indeed through reduction still has to improve the solution of security
By third party the risk for stealing decryption gesture or password is taken the photograph or peeps by stealing.And then have by hard-wired fingerprint individual verification
Increase extra cost and increase erroneous judgement may, and need prior typing fingerprint, cause the problem of convenience for shifting authority is not enough,
Also there are problems that vivo identification.One typical example is that family is public and may need to lend or need to use generation after drinking once in a while
The automobile of service is driven, the user right of its engine locking function is screened and should not just realized with fingerprint recognition.
Part producer notices that false touch of the virtual key because that can not distinguish user is operated on capacitance plate in higher sensitivity, and
The problem of false touch can not being reduced by touch feedback.The patent of Application No. 201210477444.5《Extended keyboard, electronic installation
And expanded keyboard system》A kind of main flow multi-point touch panel for utilizing and being currently based on mutual capacitance structure is disclosed, its principle is to support
Arranged on the touch-screen of multiple point touching between several additional entity buttons, different buttons and single button is calculated by touch-screen
The conductive contact quantity of bottom is mutually distinguished.But " terrible point " can be eliminated and (carry out multiple spot in single-touch location technology to touch
Touch operation, the dummy location point for actual contact can not be determined whether in coordinate statistics) multi-point touch panel need by successively
The electrical signal status of each electrode realizes multi-touch function on high frequency sweep touch-screen.When further improving number of electrodes, meeting
Full screen scanning number of times is improved with the data wire quantity on electrode anyhow both direction, this can cause the quick raising of power consumption, and control
The quick raising of the calculating performance requirement of system processed.The multiple point touching of Multi-Tounch All-Point technologies such as based on main flow
Screen, it is assumed that one piece of touch-screen constitutes touch recognition data wire by 20 lines, 30 alignments, if only needing to realize that single-point is touched
Touch, in effective recognition time of single touch --- such as the touch-screen of the frame of full screen scanning 50, the time of single sweep operation only has 20ms
---, it is only necessary to the electric signal of single data wire on coordinate anyhow is detected respectively, only need to be 20+30=50 times to screen scanning.And need
When realizing multiple point touching, to eliminate " terrible point ", it is necessary to detect the intersection point per data lines simultaneously, scanning times are increased to
20 × 300=600 times.Now, multi-point touch panel generally requires to be equipped with the processing of high performance control chip progress association, to prevent taking
The system resource of many smart machines.Also just because of the limitation of power consumption and computing capability, the multi-point touch panel (such as 7 of current main-stream
Very little following touch-screen) general only support is while recognize the detection of 5 touches, high-end scheme could support 10 touches.Therefore,
Go out the technology distinguished between multiple buttons of the conductive contact quantity variance of touch-screen contact based on detection button, work as number of keys
It is slightly many with the quantity being mutually combined, and single button upper contact quantity it is more when because touch-screen, especially common SITO
The interference problems such as the power supply noise of structure mutual capacitance touchscreens in itself, it is necessary to which it is very high to be equipped with accuracy of detection, possess while can be
Compared with the high cost touch-screen scheme that a large amount of independent touch points are detected in small area, this significantly reduces the practicality of the technology.Also
It is to say, it is simple to judge to input the technology of button by the difference of detected touch point quantity, it is too high to the performance requirement of touch-screen.
In addition, Patent No. CN201220300789.9 patent《The special touch-screen of blind person》, by increasing on the touchscreen
The voice broadcast of current touch button and the bulge-structure similar to Braille keyboard, are used with being adapted to blind person using touch-screen.But
Although such touch-screen can be realized positions virtual key with tactile, also need to reduce false touch with the relatively low touch screens of sensitivity
And using the determination button operation that is delayed again after voice message.Similarly, Fuji Tsu is that dysphotia and finger control ability are weaker
" RakuRaku " mobile phone for causing the elderly of easy false touch virtual key to design also use increase button the time required to screen
Whether the function of false touch, and notify with vibration feedback the button operation of mobile phone sense operation person.Although this can be to a certain extent
False touch is reduced, but also can seriously increase operating delay, the input speed of touch-screen is considerably reduced.

Embodiment
In Fig. 1, support 1 can be fixed on touch-screen temporarily or for a long time by vacuum cup, magnetic chuck, viscous sucker or fixture
On, while the top of support 1 is fixed with conducting end 2, inner chamber is fixed with several insulation fill blocks 3 and conductive fill block 4, and these are exhausted
Edge fill block 3 and conductive fill block 4 preferably use and are difficult to be made up of the transparent material of visual discrimination difference, can be by factory pre-sets or by user
Autonomous arrangement, different mode is mutually combined to constitute.The bottom of conducting end 2 is contacted with insulation fill block 3 and conductive fill block 4.On
State structure and together constitute the additional buttons for being securable to multiple point touching screen surfaces.
When finger does not press conducting end 2, insulation fill block 3 and conductive fill block 4 are because of the intrinsic shape disengaging touch-screen of support 1 itself；
When finger does not press conducting end 2, elastic deformation occurs for the stress of support 1, drives insulation fill block 3 and conductive fill block 4 to drop to absolutely
The position of touch-screen is close in edge fill block 3 and the conductive lower end of fill block 4.Now, finger, conducting end 2 and conductive fill block 4 constitute electricity
Logical circulation road, finally forms several multiple point touching figures for possessing accurate shape on multi-point touch panel.
Because the regular shape degree of conductive fill block 4 and dimensional accuracy of large-scale production are significantly larger than finger, so multi-point touch panel is obtained
Touch figure it is much more accurate than finger and stably, this causes the touchs figure that additional buttons are produced to possess higher when recognizing
Stability and accuracy.Therefore touch-screen can not only be produced with several the conductive fill blocks 4 detected in a shorter time period
Number of contacts, several overall contacts patterns concrete shapes constituted of conductive fill blocks 4 and mutual distribution side can also be used
Formula judges whether there occurs specific button press event.This is greatly lowered in certification, under the false proof requirement of ad eundem,
Additional buttons recognize the requirement of quantity to touch point in touch-screen multi-touch function.

--- as the unlatching key of file or encryption folder is locked or encrypted to automobile engine --- use, it is now, of the invention additional to press
Button can be played realizes the effect that identity and user right are quickly recognized instead of gesture identifications such as password and nine grids.As long as entity
Button is not stolen, authentication it is safe in easily peeped and stolen take the photograph acquisition password and gesture unblock operation.In addition, by
Not it is rigidly secured on base 1 in insulation fill block 3 and conductive fill block 4, when user often changes insulation fill block 3 and conduction is filled out
During the distribution shape of block 4, the authentication security of additional buttons can further improve.And the additional buttons that ought using are lost accidentally
During mistake, user can be reseted and be bound with usually no initial setting code using new insulation fill block 3 and conductive 4 points of fill block
Another additional buttons of mode for cloth.
Supplement is needed, removable additional buttons when re-pressing every time, its contact position and the anglec of rotation relative to touch-screen
Always changing.For assert the APP programs of button, the position of the conductive fill block 4 of several in additional buttons is simultaneously
It is inessential, and contact shape is rotated, it is only necessary to by simple two-dimensional space spin matrix computing be can be achieved it is accurate right
Than differentiating.
Fig. 2 is for another embodiment of raising authentication security.
In Fig. 2, support 1 is fixed on support multipoint touch surface, and its top is fixed with conducting end 2, and its inner chamber top is fixed with
Some insulation fill blocks 3 and conductive fill block 4.Its inner chamber lower end, which is provided with annular groove, groove, is fixed with some guide's insulation Hes of fill block 5
Guide's conduction fill block 7.Described guide's insulation fill block 5 and the conductive fill block 7 of guide and the elastic conduction ring 6 of cladding in support 1
Contact, elastic conduction ring 6 is contacted with conducting end 2 simultaneously.Therefore when finger presses conducting end 2, electric charge on finger can be with
It is transferred to all conductive fill blocks 4 and the conductive fill block 7 of guide.
User is in the additional buttons using Fig. 2 structures, and multi-point touch panel can successively obtain two groups of different touches during pressing button
Signal.It is that some guide's insulation fill blocks 5 form touch figure, followed by guide's insulation fill block 5 and conductive fill block 4 one first
Play the contact pattern of composition.The multiple point touching authentication mode that this substep is realized can be effectively improved carries out identity by non-corresponding button
With the forgery difficulty of purview certification.
Preferably, when the additional buttons of the present invention are used to detect the touch screen of function with pressure sensitivity, because being propped up in additional buttons
The modulus of elasticity of frame 1 is fixed value, so finger pressing additional buttons to touch-screen just obtains touching during specific contact information every time
If touch the pressing dynamics suffered by screen relatively --- support 1 is considered as compression spring, touch-screen is just touched
Decrement when touching signal equivalent to spring in the compression section reaches maximum, and instantaneous pressure now is close to constant value.Will
Now the instantaneous pressure data of touch-screen pressure sensor divides with the touch point quantity and concrete shape of the conductive formation of fill block 4 and position
The authentication database that cloth data add corresponding A PP together can further improve the antifalse effect of user identity and purview certification.
