Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention; Below in conjunction with accompanying drawing and preferred embodiment; Lip pencil indicating device, displacement information to proposing according to the present invention provide method and displacement information that its embodiment of system, structure, characteristic and effect thereof are provided, specify as after.
See also Fig. 1 (a), it is an existing mouse pen body vertical view and the corresponding deformation trace synoptic diagram that is shown in reference data.By can finding out among the figure, when the body of MousePen 10 points to (among the figure shown in the arrow) when consistent with the change in coordinate axis direction of reference data (x-y coordinate), the displacement of MousePen 10 on the use plane can be presented on the screen accordingly.
Yet; The difference of mode because everyone holds a pen; When the user when writing, the body of MousePen 10 points to not necessarily can keep a fixed-direction (direction shown in Fig. 1 (a) arrow), promptly; During user's practical operation MousePen 10; 10 bodies of MousePen point to the corresponding relation of MousePen 10 reality on reference data possibly exist the misalignment angle that produces because MousePen 10 is rotated, and then after the displacement information that causes MousePen 10 to be produced is transferred into computing machine, deformation trace that computer screen showed and the not corresponding phenomenon of the actual content written of user.
Moreover; Even if, let the user before using MousePen 10, after turning to the direction that meets corresponding reference data, a first body with MousePen 10 brings into use again through on MousePen 10, indicating the mode of the reference data of aliging; Promptly; With Fig. 1 (a) is example, when each user operates MousePen 10, all need a body of MousePen 10 be pointed to and adjust and turn to; Let 10 body directed forward of MousePen; Such way causes the user to divert attention noticing that a body of MousePen 10 points to, and a body that all must duplicate acknowledgment MousePen 10 when the user puts down MousePen 10 at every turn and picks up again points to, and this complicated mode of operation will cause the inconvenience of user when operation MousePen 10.
In other words; Because the user is when practical operation MousePen 10; Dynamic benchmark during MousePen 10 sensings and screen actual displayed the reference data of corresponding reference have some differences; Causing the user in the process of operation MousePen 10, must point to a body of MousePen 10 adjusts; The reference data direction of consulting and using up to computing machine and 10 of MousePens detect a body and point to consistently, could confirm the follow-up inconsistent problem of track correspondence that when writing, do not have, and the mode of adjusting 10 bodies sensings of MousePen so repeatedly will cause the sizable puzzlement of user.
See also Fig. 1 (b), its be an existing mouse pen body vertical view when being moved with the existing mouse pen in the actual displacement and the corresponding deformation trace that is presented at reference data used on the plane.The body that this figure utilizes the direction of arrow to indicate MousePen 10 equally points to; By finding out that the user is when picking up MousePen 10 among the figure; If not paying attention to a body of MousePen 10 points to; Let and differ an anglec of rotation between actual sensing and the preset reference data of 10 bodies of MousePen; So, the user utilize MousePen 10 carry out one own to cognitive when horizontal the moving, actual displayed just can receive the influence of the anglec of rotation on screen the time and form a deformation trace that is moved towards the lower right by the upper left side.
Except the sole user in operation during MousePen 10, possibly cause with the deviation of reference data outside the situation of a deformation trace that screen shows because a body of MousePen 10 points to not as expection; On the other hand, carry out in the process in meeting, if a not only man-hour of number that need to use MousePen 10, the problem that possibly cause is more complicated again.For example: when many people carry out meeting; MousePen 10 must take turns to be used for writing so that discuss by the participant; If just must find out corresponding pen holding posture again when whenever changing a user and operating, will cause being incured loss through delay of meeting and cause sizable inconvenience MousePen 10.
Therefore the present invention hopes to improve corresponding way that shows deformation trace on screen such as existing mouse pen 10 indicating devices such as grade; Utilize the sensing cell on the MousePen 10 to come sensing to obtain the program desired position offset data of revising the anglec of rotation earlier; And carry out position compensation and calculate as the foundation of revising dynamic benchmark that MousePen 10 provided and the deviation between reference data in view of the above, make the deformation trace that shows corresponding to the displacement of MousePen 10 on the screen more consistent with the real-life operational situation of user on the use plane.
See also Fig. 2, its displacement information that is applied to displacement information and provides system that is the present invention proposes provides the core procedure process flow diagram of method.Use an indicating device (as: MousePen etc.) and a controlled device (as: personal computer) that displacement information proposed by the invention provides the displacement information of method that system is provided to comprise at least one lip pencil; This displacement information provides between the indicating device and controlled device that method is applied to this lip pencil, and it mainly may further comprise the steps:
In response to the user moved indicating device carries out, rotation or upset and cause indicating device with respect to the change in location of using the plane, utilize sensing cell to carry out sensing and obtain displacement information, pitch angle information and rotary angle information (step S21) for these change in location; After obtaining above-mentioned all types of sensitive information, controlled device then carries out the offset estimation program according to these sensitive informations, and obtains position compensation data (step S23) by the offset estimation program; And after obtaining the position compensation data, whether contact the state that uses the plane according to indicating device, and then whether decision changes deformation trace pairing display mode (step S25) on controlled device of indicating device according to the position compensation data.
Be noted that; In step S25; If judge that whether indicating device contacts the judged result of using the plane is to negate, representative of consumer possibly just brought indicating device and play conveniently, though therefore the sensing cell sensing draws indicating device with respect to the change in location of using the plane; But these change in location do not need to be presented on the controlled device by correspondence, so the position compensation data only have been stored the basis that is used as the computing of next record position compensation; If step S25 judges that whether indicating device contacts the judged result of using the plane is certainly; Representative of consumer is utilizing indicating device to write; Displacement information provided system and was used as next return and moves the reference basis of estimation program except the position compensation data storing is risen this moment, also can utilize the result of position compensation data and changed indicating device corresponding deformation trace that shows on controlled device.
See also Fig. 3 (a), it is an indicating device body vertical view and the corresponding direction synoptic diagram that is shown in reference data that the present invention proposes.In this figure; Indicating device 20 can correspondence rotate identical angle corresponding to a body rotational angle of indicating device 20 corresponding to the reference data that is shown on the screen (x-y coordinate); Also be; The direction of pairing x-y coordinate when the objective of the invention is to change actual displayed indicating device 20 lets the reference data the calculated dynamic benchmark can be with indicating device 20 actual moving the time be parallel to each other.Be noted that the reference data here only is the basis of being consulted and used when position compensation is estimated, therefore the x-y coordinate that the user sees on screen can't rotate.
See also Fig. 3 (b), actual displacement and the corresponding deformation trace that is presented at reference data when its indicating device body vertical view that is the present invention proposes is moved on using the plane with indicating device 20 proposed by the invention.By finding out among the figure; After obtaining the position compensation data and carrying out compensation operation; Because reference data is consistent with dynamic benchmark, the deformation trace on the mobile and reference data of indicating device 20 also can be consistent, so indicating device 20 deformation traces of screen display just can not produce deviation.
For the purpose of explanation; Above-mentioned is to explain with two-dimensional coordinate about the actual displacement of indicating device 20 and the corresponding relation of the displacement on the screen; What but indicating device 20 maybe be as three-dimensional with respect to the change in location of using the plane; Therefore the present invention also will consider perpendicular to the variable quantity that uses on the in-plane when realizing position estimation, and the detailed rule of doing sees also following explanation.
See also Fig. 4 (a), it is displacement information of the present invention provide system to arrange in pairs or groups a synoptic diagram that single indicating device writes.Displacement information provided by the present invention provides system mainly to be made up of indicating device 20 (as: MousePen, digital MousePen etc.) and controlled device 21 (as: computing machine etc.); Signal is connected through R-T unit 23 between indicating device 20 and the controlled device 21; Also be; Utilize R-T unit 23 to receive the multidate information that indicating device 20 is transmitted; And further again multidate information is sent to controlled device 21, whether controlled device 21 contacts according to indicating device 20 and uses the plane behind the multidate information that receives indicating device 20; And then the only simple compensation result that stores or upgrade the position offset data of decision, or the deformation trace of while update displayed indicating device 20 on screen 211.
See also Fig. 4 (b), it is displacement information of the present invention provide system to arrange in pairs or groups a synoptic diagram that a plurality of indicating devices write.This figure has explained that displacement information provides system can utilize a plurality of indicating device 201～20n collocation controlled devices 21 to use simultaneously; Each indicating device 201～20n at first carries out exchanges data with modes such as wireless signal connection and R-T unit 23, and R-T unit 23 further is sent to the controlled device 21 that is connected with its signal with the pairing multidate information of each indicating device 201～20n again.
Compare with Fig. 4 (a); In case displacement information provides indicating device 20 quantity in the system when being a plurality of; Displacement information shown in Fig. 4 (b) provide system further distribution marker in each lip pencil indicating device 201～20n; After letting controlled device 21 receive multidate information, when carrying out identification with corresponding processing displacement data, can according to pairing identifier confirm each lip pencil indicating device 201～20n dynamically.
On the other hand; When the indicating device 201～20n of individual other lip pencil transmits multidate information in response to user's operation; Also in the lump identifier is sent to controlled device 21 through the delivery unit in the indicating device 201～20n of lip pencil, the corresponding relation when controlled device 21 changes each indicating device 201～20n and distinguishes corresponding cursor and on controlled device 21, show change in displacement according to the position compensation data of identifier and other indicating device 201～20n more afterwards.
Thus; Controlled device 21 just can receive the dynamic of a plurality of indicating device 201～20n simultaneously; And differentiate the multidate information that each indicating device 201～20n is transmitted according to identifier; And according to each indicating device 201～20n whether contact uses plane, the use of collocation position offset data changes each indicating device 201～20n by application program for the processing of relevant information and goes up pairing track and display mode at the screen 211 or a display device (figure does not show) of controlled device 21; For example: utilize red track to indicate the change in displacement of first indicating device 201; And indicate the modes such as change in displacement of second indicating device 202 with the track of blueness, and utilize various colors or marker method, the handwriting trace of different indicating device 201～20n is simultaneously displayed on the screen 211.
Moreover; What no matter displacement information provided system's collocation is the situation of a plurality of indicating device 201～20n shown in the single indicating device 20 shown in Fig. 4 (a) or Fig. 4 (b); The Data Transport Protocol that is utilized as the R-T unit 23 of controlled device 21 and indicating device 20 transmission mediums can't influence way of the present invention; Therefore no matter various types of Data Transport Protocols are through wired, wireless, sequence, form such as arranged side by side, can be used and as the data exchange ways of 21 of indicating device 201～20n, R-T unit 23, controlled device.
For instance, R-T unit 23 can be via data transmission interfaces such as USB and is carried out exchanges data and communication with computing machine; On the other hand; R-T unit 23 and indicating device 20; As: between digital MousePen then can through different wireless network transmissions forms as: modes such as IEEE 802.15.4 (ZigBee), bluetooth or infrared ray are carried out data transmission and communication; Certainly, the data transmission format during practical application can't influence the flow chart of data processing of the present invention for sensitive information.
See also Fig. 4 (c), it is the indicating device organigram with position compensation function that the present invention proposes.Under the use habit of considering general user; The indicating device 20 of controlled device 21 of being used among Fig. 4 (a) and Fig. 4 (b) arranging in pairs or groups is designed to have the lip pencil outward appearance; The lip pencil indicating device 20 here mainly comprises: the housing 31 of pen-like shape and be arranged on the sensing cell 32 in the housing 31; Wherein sensing cell 32 is used to when the user operates indicating device 20; Indicating device 20 is carried out sensing and obtains displacement information, pitch angle information and rotary angle information with respect to the change in location of using the plane; Move the relevant sensitive information of situation according to the above-mentioned all types of and indicating device 20 that draws by sensing cell 32 sensings and carry out the offset estimation program, arrange in pairs or groups and obtain controlled device 21 needed position compensation data when correspondence shows indicating device 20 displacement situations by this kind.
Except sensing cell 32; The use of indicating device 20 all right further collocation control modules 33 and transmit receive unit 34; Through the mode that is electrically connected; Displacement information, pitch angle information and the rotary angle information etc. that control module 33 can sense sensing cell 32 corresponding to indicating device with respect to the change in location of using the plane and change in location information and sensed quantity that sensing obtains are utilized transmit receive unit 34 and controlled device 21 to carry out exchanges data and used.Certainly; The control module 33 that is built in indicating device 20 in the process of actual computation offset estimation program no doubt can be utilized carries out; Also maybe be under the situation of taking into account system operand, directly these sensed quantity are sent to controlled device 21 and are undertaken by controlled device 21.
See also Fig. 5, its displacement information that is the present invention proposes provides the operational flowchart of method.At first start the displacement information adjusting function (step S501) of indicating device; Then utilize and be installed in the inner employed all types of sensing cell sensings of indicating device and obtain different dynamic sensed quantity (step S511～S514).
In this operational flowchart, indicating device is used for the mode of sensing and comprises: utilize optical displacement sensor or trace ball displacement transducer to detect indicating device moving and obtain the displacement sensing amount (step S511) of X, Y on reference data; Read the acceleration magnitude (step S512) of indicating device on x axle, y axle and z axle through acceleration transducer; And read the indicating device anglec of rotation (step S513, S514) that gyroscope, geomagnetic sensor detect.
After obtaining sensed quantity such as displacement sensing amount, acceleration, the anglec of rotation; Operating process of the present invention then utilizes fuzzy theory (Fuzzy Theory), Kalman filtering algorithm modes such as (Kalman Filter) to carry out the offset estimation program to indicating device; And then after drawing position compensated informations (step S515) such as pen holding posture, displacement sensing amount and a body anglec of rotation; State with previous indicating device is the basis, utilizes the position compensation data that the dynamic change of indicating device is compensated (step S520).
Additional disclosure be used for representing indicating device with respect to the dynamic change of using the plane like pen holding posture, amount of movement and a body anglec of rotation etc.; Can utilize the sensed quantity that sensing cell sensed such as optical displacement sensor, trace ball displacement transducer, acceleration transducer, gyroscope or geomagnetic sensor, the use of collocation offset estimation program and calculate out.
The step of carrying out at last then is whether the nib of judging indicating device contacts on the use plane (step 521); If, just upgrade the cursor position that indicating device 20 correspondences are presented at screen according to the use location offset data, and upgrade the position dynamic (step S522) of indicating device; If not, then upgrade in the displacement information providing system position dynamic about indicating device according to operation result, but can not upgrade in view of the above and synchronously indicating device on controlled device the corresponding cursor position (step S523) that shows.
For the displacement information that uses a plurality of indicating device collocation controlled devices provides system; Above-mentioned data processing and control flow are also roughly the same; Unique difference is; Identifier under when the planning displacement information provides system, need defining each indicating device earlier, and individual other indicating device also must provide affiliated identifier in the lump when transmitting sensitive information; When controlled device connect through signal obtain the identifier and location sensing information that each indicating device sends after; Controlled device just can change the display mode of the pairing pointer of each lip pencil indicating device according to identifier and position compensation data.
Lip pencil indicating device proposed by the invention is connected in controlled device through mode signals such as blue bud or infrared rays;, utilize the sensing cell of difference in functionality and detect indicating device like optical displacement sensor, trace ball displacement transducer, acceleration transducer, gyroscope or geomagnetic sensor etc. through the sensing cell in the indicating device because operation behaviors such as the user carried out moves, rotation or upset cause indicating device with respect to the change in location of using the plane.After obtaining the needed displacement information of offset estimation program, pitch angle information and rotary angle information; Can be in real time estimation result's mode is handled and drawn to sensitive information by fuzzy algorithm and Kalman filtering algorithm etc., the mobile of indicating device estimated.
In addition; The lip pencil indicating device more optionally provides delivery unit; Delivery unit is electrically connected on sensing cell; So as to obtaining the various sensitive informations that sensing cell institute sensing obtains, again through the signal ways of connecting, the relevant information of required use was sent to controlled device when these were estimated displacement.
In order to illustrate further implementation of the present invention, below just the flow process of displacement information providing method is done further explanation:
