Explanation through above-mentioned touch key-press structure can be seen; In the time will operating to said touch key-press structure; User's finger is not directly to touch charged electrode to realize to the influence of the quantity of electric charge in the charge accumulation area, but has contacted metal key-press.
The principle that causes above-mentioned situation to occur is, when each electrode has produced the source electric field separately after charging, said source electric field is an electrostatic field, and forms charge accumulation area at each electrode surface.When user's finger touches metal key-press, can make said Electric Field Distribution change, cause the transfer of electric charge in the charge accumulation area, thereby variation has taken place in the quantity of electric charge in the charge accumulation area.
This shows, change, generally just can think that touch operation has taken place said electrode corresponding key in case the violent quantity of electric charge has taken place in the charge accumulation area of certain electrode.Thereby; Just can obtain button in the quantity of electric charge sample value that faces charge accumulation area corresponding when touching based on this situation, and definite electric charge sample value is the generation of touch event less than the situation of touch sensible threshold value through charge accumulation area being carried out mode that electric charge replenishes.
Correspondingly; The control device of space mouse links to each other with each electrode on the said detecting plate; Detect electric charge transfer case on each electrode to obtain corresponding electric charge sample value, said touch operation is discerned, and produced the identification control signal to control the operation of said space mouse according to recognition result; Wherein, said detection comprises:
When the touch key-press structure faced touch or closes on touch, the corresponding voltage of total amount of electric charge that record shifts from each electrode reached the number of times of reference voltage;
The number of times that reaches reference voltage with the corresponding voltage of total amount of electric charge that shifts on each electrode is as the electric charge sample value of said electrode corresponding key when said touch key-press structure faces touch or closes on touch;
The electric charge sample value is identified as the button that is touched less than the button of touch sensible threshold value.
Said control device comprises: a plurality of specific capacitances, a plurality of voltage detecting and comparing unit, counting unit, discriminance analysis unit, operation control unit, wherein,
A plurality of specific capacitances, respectively with the touch key-press structure in each electrode pair should be connected;
A plurality of voltage detecting and comparing unit with the corresponding connection of said a plurality of specific capacitances, detect corresponding specific capacitance voltage respectively, when said specific capacitance voltage reaches reference voltage, and the output count signal;
Counting unit connects a plurality of voltage detecting and comparing unit, the count signal of each voltage detecting and comparing unit output is counted, and the count value of the count signal of each voltage detecting and comparing unit output is sent to the discriminance analysis unit;
The discriminance analysis unit faces in said touch key-press structure as each electrode corresponding key with the count value of the count signal of each voltage detecting and comparing unit output and to touch or close on the electric charge sample value when touching; The electric charge sample value is identified as the button that is touched less than the button of touch sensible threshold value; Said identifying information is sent to operation control unit;
Operation control unit receives said identifying information, and produces the identification control signal to control the operation of said space mouse according to the said preset function that is identified as the button that is touched.
Combine accompanying drawing that the control method of above-mentioned space mouse is done further explanation below again.
With reference to Fig. 4, the control method of space mouse shown in Figure 1 roughly may further comprise the steps:
Step s1, when the touch key-press structure of space mouse faced touch or closes on touch, the corresponding voltage of total amount of electric charge that the control device record shifts from each electrode reached the number of times of reference voltage;
Step s2, the number of times that reaches reference voltage with the corresponding voltage of total amount of electric charge that shifts on each electrode is as the electric charge sample value of said electrode corresponding key when said touch key-press structure faces touch or closes on touch;
Step s3 is identified as the button that is touched with the electric charge sample value less than the button of touch sensible threshold value;
Step s4, the control device of space mouse is according to the said operation that is identified as the preset function control space mouse of the button that is touched.
In addition; Before carrying out said touch recognition; Also need carry out some initialization procedures, comprise: detection background ambient signal, the extraneous signal of shielding first frequency (being 80KHz in the present embodiment) to second frequency (being 120KHz in the present embodiment); Behind the signal in detecting said first frequency to second frequency scope, produce trigger pip.Said trigger pip triggers said touch recognition process.
Fig. 5 shows a kind of realization synoptic diagram of the control method of space of the present invention mouse; In the touch key-press structure of said space mouse; The material of metal touch panel and button is copper; The material of the insulation course between button and metal touch panel is a glass, and the electrode corresponding with key position is Copper Foil on the detecting plate.
When finger touch or close on when touching on the copper film a certain button, electric charge will some be escaped through human body, and produces electric charge via the corresponding Copper Foil of said key position and shift.For the situation of learning that said electric charge shifts, can adopt the means of voltage detecting.
With reference to shown in Figure 6, can each Copper Foil in the said touch key-press structure be linked to each other with said control device, include a plurality of specific capacitances in the said control device, each Copper Foil respectively with said control device in the corresponding connection of a specific capacitance.As aforementioned, when finger touch or close on when touching on the copper film a certain button, the electric charge of escaping from human body is understood some and is produced electric charge via said Copper Foil and shift.And because specific capacitance has existed with said Copper Foil and has been electrically connected, electric charge will shift by the specific capacitance in control device, and this process promptly is equivalent to the specific capacitance in the control device is charged.Because the voltage at electric capacity two ends is easy to record, therefore can detect the situation that electric charge shifts that obtains through voltage to the specific capacitance two ends.
Particularly, adopt the less specific capacitance of electric capacity, can adopt the electric capacity of pF level usually, for example 0.5pF.Like this, specific capacitance is full of by the electric charge that shifts from Copper Foil with regard to being easier to.Based on this, through voltage detecting in the control device and comparing unit, the voltage (reference voltage) at two ends compared when the voltage at specific capacitance two ends and said specific capacitance were full of, and just can learn whether said specific capacitance is full of.
Because finger touch or close on touches on the copper film in a certain button process, the electric charge that shifts via said Copper Foil possibly be full of required electric charge greater than specific capacitance, and a plurality of discharge circuits corresponding with specific capacitance quantity also can be set in control device.When voltage detecting in control device and comparing unit detected the specific capacitance voltage and reach reference voltage, said discharge circuit just started the discharge to specific capacitance.Because the electric capacity of specific capacitance is less, therefore also be easier to, and then the discharge required time seldom by said discharge circuit rapid discharge.Thereby, can guarantee the accuracy of whole touch recognition process.After to the specific capacitance discharge, specific capacitance will be full of by the electric charge that shifts via Copper Foil again, will experience discharge once more subsequently again, and this process circulates until finger touch always or closes on the release that touches a certain button on the copper film.
Because voltage detecting and comparing unit can be exported count signal when the specific capacitance voltage reaches reference voltage, then at above-mentioned finger touch or close on touch action when finishing, voltage detecting and comparing unit will be exported a plurality of count signals.Based on this, just can record the count value of corresponding count signal through the counting unit in the control device, said count value just can be used as said touch key-press structure and faces the electric charge sample value that touches or close on respective keys when touching.
After obtaining the corresponding electric charge sample value of each button, just can analyze through the discriminance analysis unit in the control device, the electric charge sample value is identified as the button that is touched less than the button of touch sensible threshold value.Thereby, accomplish this touch recognition process.
In order to make the control method of above-mentioned space mouse more explicit, the actual operating position in the face of the user further specifies down.
In the present embodiment, control device can be controlled said space mouse and realize left button function, right button function and draw runner unlocking function.Certainly, state in realization before three kinds of functions, control device need confirm at first whether said space mouse is in starting state.
Particularly, in the present embodiment, through preestablishing, the button 1 shown in Fig. 2 and 2 is identified as when being touched button simultaneously, and said space mouse starts.Therefore; Corresponding to user's actual use situation, when user's touch key- press 1 and 2 simultaneously, and when making the electric charge sample value of said button 1 and 2 correspondences all less than the touch sensible threshold value; Said space mouse controlled device starts, thereby makes the user can carry out other operations.And said space mouse is not when being activated, and user's touch action can not impact the space mouse, therefore, can avoid misoperation of users effectively.
When the control device of space mouse detects after said space mouse is in starting state, the user just can carry out other operations.For example; When user's touch key-press 1; And when making the corresponding electric charge sample value of said button 1 less than the touch sensible threshold value; Said button 1 is identified as the button that is touched, and the operation control unit of so said control device is realized the operation to the space mouse based on said identifying information, promptly starts the left button function of said space mouse.Thereby the user can accomplish according to the left button function of said space mouse and choose, confirm or other operations.
Equally, the user can be the button of right mouse button function through touching preset function also, and promptly button 2 is carried out the right button function of space mouse.Because this process is similar by the realization of the left button function of above-mentioned space mouse, so repeat no more at this.The user just can open its right button shortcut menu after the right button function that has started mouse.Then, the user just can control the cursor of space mouse, moves it certain option in the right button shortcut menu, and through touch key-press 1, realizes choosing function.
More than specified the realization of the right and left key function of space mouse, and when the user did not operate the space mouse for a long time, said space mouse will get into lock-out state.Under this lock-out state, the user can't carry out the right and left key feature operation of space mouse, that is to say, even button shown in Figure 21 or 2 is touched, control device is the right and left key function of start-up space mouse not also.At this moment just need the user to carry out the draw runner unlocking function of space mouse.
In the present embodiment; Predefined continuous button 3～5 is touched successively, and said button 3～5 is when being identified as touch key-press in the given time simultaneously, the draw runner unlocking function of control device start-up space mouse; Wherein, the scope of the said schedule time is for being less than or equal to 2s.In the practical operation specific to the user; User's finger slips over continuous button 3～5 successively, and is being less than or equal in the time of 2s, and the corresponding electric charge sample value of said button 3～5 is during all less than the touch sensible threshold value; The discriminance analysis unit of control device is identified as the button that is touched with button 3～5; And operation control unit will produce control signal according to the preset function of button 3～5 behind this identifying information that receives, thereby realize the draw runner unlocking function of space mouse.
After by the way the space mouse being carried out release, the user can carry out other operations to the space mouse again according to the actual requirements.For example, can carry out the left button function of space mouse, perhaps carry out the right button function of space mouse through touch key-press 2 through touch key-press 1.Certainly, also can operate, realize other functions other buttons of space mouse.
More than disclose many aspects of the present invention and embodiment, it will be understood by those skilled in the art that others of the present invention and embodiment.Disclosed many aspects and embodiment just are used to illustrate among the present invention, are not to be to qualification of the present invention, and real protection domain of the present invention and spirit should be as the criterion with claims.
