Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with the specific embodiment of the invention and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Trace input device provided by the invention, the touch-screen communicated with and track input system, may be used for writing pencil and in the touch-screen that communicates with writing pencil.Writing pencil is such as active capacitance pen, in the present invention, when trace input device is in outside the track input area of touch-screen, and pressure transducer is when pressure sensitive signal being detected, pressure sensitive signal is realized non-track input function as functional simulation signal, namely by multiplexing pressure sensitive signal, pressure sensitive signal is changed into a series of analog quantitys corresponding to the continuous of required control signal and/or Discrete Change, thus, except realizing except the application of pressure sensitive signal in handwriting input process, the controlling functions of other unscripted input can also be completed.Particularly, the control action such as volume adjusting, mouse roller is such as realized.Also can by arranging a pressure threshold, when the pressure of pressure sensitive characterization is greater than set above-mentioned pressure threshold, pressure sensitive signal is converted into functional simulation signal and realizes non-track input function, or when the pressure of pressure sensitive characterization is greater than set above-mentioned pressure threshold, think that once special button triggers, and complete corresponding function.
Be described below in conjunction with the input function of accompanying drawing to trace input device of the present invention and realization thereof.
Fig. 1 shows the structured flowchart of the track input system that trace input device according to one preferred embodiment of the present invention and the touch-screen that communicates with are formed.As shown in Figure 1, described track input system comprises touch-screen 1 and trace input device 2 matching used with this touch-screen 1.In embodiments of the present invention, take trace input device as writing pencil for example is described.At the preset range of this touch-screen 1, track input namely in track input range, can be realized.This writing pencil 2 can be electromagnetic type, also can be capacitive, thus to launch electromagnetic induction or capacity coupled mode realizes communicating between writing pencil with touch-screen, comprises and realize track input etc.Represent for capacitive coupling in Fig. 1.
As shown in Figure 1, described touch-screen 1 comprises communication module 11, and such as bluetooth module or WiFi module etc., for realizing the communication function of touch-screen, carry out radio communication with the wireless communication unit 22 of writing pencil; Track input area 12, for the medium providing track to input for described trace input device, when in the track input area that trace input device is in touch-screen, realizes track input function; And controller 13, for performing the startup etc. of corresponding judgement, function.Hereafter will be specifically described.In addition, mutual in order to what realize with writing pencil, this touch-screen can communicate with writing pencil in the mode of capacitive coupling or electromagnetic induction.
Described writing pencil 2 comprises pressure transducer 21, wireless communication unit 22 and control module 23.Pressure transducer 21 is for detecting the pressure that is applied on writing pencil and being converted into electric signal.Pressure transducer 21 is preferably capacitance pressure transducer, and can also be the pressure transducer of other types certainly, the present invention limit this, is applied to pressure on writing pencil and output pressure induced signal as long as can detect.
In the present invention, the position of pressure transducer is not only confined to the input end (such as: the nib of writing pencil) being arranged on trace input device, be convenient to position that hand grips or the end relative with the input end of trace input device (such as: a tail of writing pencil) also can arrange one or more pressure transducer simultaneously at trace input device, the pressure sensitive signal that the pressure transducer being positioned at diverse location detects separately or can coordinate the control of a series of simulating signal, switch or push button signalling.Wireless communication unit 22, for realizing the radio communication with touch-screen 1, it can be the communication module such as bluetooth module or WiFi module.Control module 23, in order to realize corresponding controlling functions, the pressure sensitive signal such as sensed according to pressure transducer 21 judges whether to need wirelessly to send signal etc. to above-mentioned touch-screen.Particularly, outside the track input area that trace input device is in touch-screen, and pressure transducer 21 is when pressure sensitive signal being detected, control module 23 controls wireless communication unit 22 and pressure sensitive signal is sent to touch-screen, and pressure sensitive signal is converted into functional simulation signal and realizes non-track input function.Outside track input area can be on touch-screen preset track input area outside region, also can be other places outside touch-screen, be other local time outside touch-screen outside track input area, now pressure sensitive signal sends to touch-screen by communication.The pressure size of pressure sensitive characterization can be mapped as different non-track input functions, thus realize the control to the non-track input function of continuous analog.
In addition, when pressure transducer 21 is arranged on multiple position of writing pencil 2, control module 23 is for identifying pressure sensitive signal is from which pressure transducer.And the pressure sensitive signal of touch-screen will be sent to be designated different pressure sensitive signals according to different pressures source, size etc., different types of pressure sensitive signal can be identified to make touch-screen, and trigger different non-track input functions according to setting in advance accordingly, namely realize the switching between different non-track input function according to different types of pressure sensitive signal.
When pressure transducer 21 is arranged on tail of writing pencil, except realizing except non-track input function as functional simulation signal using the pressure sensitive signal that the pressure transducer being arranged at a tail exports, the function such as switch of erasing rubber, writing pencil also can be realized.
Illustrate that trace input device of the present invention realizes the process flow diagram of non-track input function below in conjunction with Fig. 2.As shown in Figure 2, writing pencil 2 utilizes pressure transducer 21 to detect the pressure be applied on writing pencil, and is converted into pressure sensitive signal.For condenser type writing pen, once produce pressure sensitive signal, then writing pencil is with communication or simultaneously with capacitive coupling and communication, and above-mentioned pressure sensitive signal is sent to touch-screen.When pressure sensitive signal can be sent to touch-screen with capacitive coupling and communication by writing pencil simultaneously, by capacitive coupling, pressure sensitive signal is sent to the priority of touch-screen higher than the priority by communication, pressure sensitive signal being sent to touch-screen.Herein, in order to the interference between anti-stop signal, above-mentioned pressure sensitive signal also can utilize capacitive coupling and the communication of timesharing be sent to touch-screen by writing pencil.Particularly, such as, when pressure transducer 21 detects pressure, output pressure induced signal, control module 23 controls wireless communication unit 22 and with communication, described pressure sensitive signal is sent to touch-screen with a predetermined delay, makes the transmission of communication be later than the transmission of capacitive coupling.Because writing pencil self can not judge whether pressure sensitive signal to be successfully sent to touch-screen by capacity coupled mode, therefore, can guarantee that touch-screen successfully receives pressure sensitive signal by capacitive coupling and communication.
After touch-screen receives above-mentioned pressure sensitive signal, judge whether current input pattern is in track input pattern.If described writing pencil is in track input pattern, then to judge in the track input range whether writing pencil is in touch-screen (the writing in scope of software being such as used for handwriting input at touch-screen detects writing pencil), if writing pencil is in the track input range of touch-screen, then the controller 13 of touch-screen conveniently touches the mode of input, carries out track input according to the actual pressure sensitivity that above-mentioned pressure sensitive signal characterizes; If writing pencil is in outside the track input range of touch-screen, then pressure sensitive signal is realized non-track input function as functional simulation signal.
If current input mode is in non-track input pattern, then pressure sensitive signal is realized non-track input function as functional simulation signal.Current input mode is in non-track input pattern can following two kinds of situations: a kind of situation, pressure not produces on the touchscreen, but, such as that user points and is applied on writing pencil, then control module 23 controls wireless communication unit 22, above-mentioned pressure sensitive signal is sent to touch-screen with communication, the communication module 11 of touch-screen receives this pressure sensitive signal, controller 13 is multiplexed with functional simulation signal, start non-track input function, such as volume adjusting, screen intensity, mouse roller, page turning, explain the control in ppt process and open application software etc. on touch-screen.Another kind of situation, when within the scope of such as certain software controlled for non-writing that writing pencil is in touch-screen, and is in the required keys upwards that controls and has pressure sensitive signal to be sent to touch-screen with capacitive coupling and wireless mode.Then the controller 13 of touch-screen this pressure sensitive signal multiplexing, starts non-track input function, specific non-track input control such as carrying out described software etc.Below only for condenser type writing pen, applicable equally for electromagnetic type writing pencil, repeat no more herein.
Mode shown in Fig. 2, for triggering, namely starts one of plain mode of unscripted input (non-track input).The triggering mode of the controlling functions of unscripted input has multiple.Such as, pressure is applied in a specific keys of writing pencil 2, starts a certain specific software; Position pressing nib beyond the track input area of touch-screen, and by pressing the size adjustment volume of nib dynamics; And certain location point on touch-screen under non-track input pattern hits the nib of writing pencil, and start a certain software when dynamics is greater than a certain threshold value; Or start when the position beyond the track input area of touch-screen exceedes scheduled duration by a certain button on pressing nib or a certain writing pencil and realize brightness adjustment etc.Below in conjunction with two kinds that specific embodiment illustrates wherein.
Fig. 3 shows the process flow diagram of another preferred embodiment realizing non-track input function according to trace input device of the present invention.As shown in Figure 3, when pressure generation not from the track input area of touch-screen time, control module 23 first judges whether the pressure that pressure sensitive signal characterizes is more than or equal to default pressure threshold, if, then control module 23 controls wireless communication unit 22 and wirelessly launches above-mentioned pressure sensitive signal to touch-screen, above-mentioned signal multiplexing from writing pencil 1 is functional simulation signal by the controller 13 of touch-screen, namely for realizing non-track input function, particularly, realize the startup of the controlling functions of non-track input, such as carry out volume adjusting or start drawing boards, softwares such as word etc.If pressure is less than above-mentioned pressure threshold start an other non-track input function (now, with the operation of the scheme shown in Fig. 2).Or, obvious, can not start any function as maloperation yet.The combination of such scheme or different schemes can according to the structure of writing pencil, and need the non-track input function started to determine.
Fig. 4 shows the process flow diagram of the another preferred embodiment realizing non-track input function according to trace input device of the present invention.As shown in Figure 4, when the generation of pressure is not in the track input area of touch-screen, such as that user press...withes one's finger and puts pen to paper a nib, or hold writing pencil and click screen with exterior domain, control module 23 first judges whether the pressure that pressure sensitive signal characterizes is more than or equal to a threshold value, if it is judge whether pressure duration reaches a threshold value further, the words being then start a unscripted input function, such as, open certain software etc. as above.No words then start another unscripted input function, such as, open another software etc.Obviously, for pressure size and duration use capable of being combined, also can respectively as the trigger condition of certain unscripted input function.
In addition, the control of above-mentioned unscripted input can also realize certain unscripted input control with key combination, such as in specific DASE, a specific control is shown in the specific region of touch-screen, when use writing pencil click and this region of Continued depression time, specific setting can be adjusted according to the change of the pressing dynamics be applied on writing pencil.The setting in such as month and date, by clicking the numeric area of required setting and pressing button corresponding on writing pencil, control the size of pressing dynamics, numeral of just can rolling fast is to complete input (can by the digital fast scroll of the 1-12 month as passed through pressing dynamics size variation) efficiently.
Or, carry out corresponding control operation when writing pencil is in touch-screen so that button also can be coordinated during exterior domain.Such as in a certain demo environment, press nib by the button pinning writing pencil corresponding simultaneously, the operating function that rapid page or similar mouse roller roll can be completed, the pressing dynamics size be applied on writing pencil can control the speed of page turning, different pressing dynamics even can correspond to different page number etc. by step-length.
The trace input device that the embodiment of the present invention provides, the touch-screen communicated with and track input system, the pressure sensitive signal that pressure transducer in trace input device detects can not only simulate written handwriting, by using pressure sensitive signal as functional simulation signal, can also carry out quick, convenient to the control situation of continuous analog and control efficiently, do not need to arrange extra button on trace input device, simplify the structure of trace input device.
Below by reference to the accompanying drawings the solution of the present invention is described, the present invention by the pressure sensitivity data of writing pencil except being used for writing except input, pressure sensitivity signal can also be utilized under particular circumstances to realize other controlling functions, thus a kind of convenient, unscripted input control is efficiently provided.
The foregoing is only embodiments of the invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
