It is only to be not intended to limit the invention merely for for the purpose of describing particular embodiments in terminology used in the present invention. It is also intended in the present invention and the "an" of singular used in the attached claims, " described " and "the" including majority Form, unless the context clearly indicates other meaning.It is also understood that term "and/or" used herein refers to and wraps It may be combined containing one or more associated any or all of project listed.
It will be appreciated that though various information, but this may be described using term first, second, third, etc. in the present invention A little information should not necessarily be limited by these terms.These terms are only used to for same type of information being distinguished from each other out.For example, not departing from In the case where the scope of the invention, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as One information.Depending on context, word as used in this " if " can be construed to " ... when " or " when ... When " or " in response to determination ".
Intelligent terminal with touch function, can apply meeting, teach, outdoor live streaming etc. needs the field of touch function Under scape.In order to adapt to scene demand, subtly touch-control response is may be implemented in the touch-control system of intelligent terminal.Under certain scenes, touching One pixel of the every variation in position is touched, touch-control system at least needs to report the touch data of a sub-band touch position data, wherein touching Touching position data indicates touch location, and may also be referred to as position of touch or writing position under the certain scenes of touch location.It is adjacent The touch location gap reported twice can correspond to a pixel, i.e., the variation of the adjacent touch location reported twice is less than or waits In a pixel unit.This shows that a pixel unit includes at least a touch control unit, which indicates touch-control system The minimum unit that can be distinguished, the minimum unit that can be distinguished is smaller, and the touch precision of touch-control system is higher, touch precision here Touch accuracy can be referred to as or write fineness.
The designer of the present invention program passes through repeatedly the study found that touch-control system is the types such as capacitor, resistance, pressure sensitivity It is less during fine touch-control the phenomenon that cursor is frequently shaken occur when touch-control system.And touch-control system is the touching of electromagnetic type When control system, if time writer touches screen, that is, when being in writing state, subtly touch-control is responded, and writing essence can be improved Fineness.
If time writer is suspended in (situation in the case where a certain range of space of screen not in contact with arriving screen It is referred to as suspended state in the present invention), during finely responding touch-control, often there is the phenomenon that cursor is frequently shaken.Here The a certain range mentioned is determined by the effective range that magnetic board can sense electromagnetic signal.
The designer of the present invention program has found that time writer is suspended in apart from screen one after further researching and analysing this phenomenon When determining the space of range, the magnetic board in touch-control system can equally sense the electromagnetic signal and magnetic flux of time writer transmitting Variation, the frequency of the electromagnetic signal sensed, the frequency of the electromagnetic signal issued when being in writing state different from time writer, In response, operating system controls display screen display highlighting.
Although cursor is shown in display screen, precise controlling when for guaranty write state, even non-writing When state, a pixel unit also includes at least a touch control unit, and touch location one pixel of every variation, touch-control system is at least It needs to report a touch data.Then, the operating system docked by touch-control system, control cursor position follow touch location Change and changes.
The designer of the present invention program has found in turn, in the case where touch-control system finely responds position of touch variation, If time writer is suspended in apart from a certain range of space of screen, user's arm can not be from shake, the unconscious shifting of body pressed down It moves, can cause the variation of time writer position and the variation of position of touch.The variation of position of touch easily causes touch-control system The position of touch of variation is frequently reported, this is easy for the phenomenon that cursor is frequently shaken occur, and cursor is frequently shaken and can be caused not Necessary resource consumption.In view of this, designer of the invention proposes a kind of processing method of touch data.
The processing method of the touch data can be in time writer by judging the current state of time writer and write shape When state, the touch data of the time writer is determined according to the first operating mode；When time writer is in suspended state, according to second Operating mode determines the touch data of the time writer, the corresponding touch precision of the position of touch determined, is lower than writing state When the first operating mode under touch precision, can thus reduce the change frequency of cursor position, and then reduce light as far as possible Target is frequently shaken, and unnecessary resource consumption is avoided.
Below in conjunction with attached drawing, first a kind of system of the processing of the lower touch data for realizing the embodiment of the present invention of explanation:
Figure 1A is please referred to, Figure 1A is the frame of the processing system 100 of the touch data shown in an exemplary embodiment of the invention Composition, the processing system 100 may include touch-control system 120.Touch-control system 120 and electromagnetical type touch screen and host equipment 140 Docking, may include the touch sensor (magnetic board 121 in such as Figure 1A) and touch-control processor 122 of electromagnetic type, host equipment 140 It is interior equipped with operating system 141.
In practical application, touch-control system 120 can be mounted on electromagnetical type touch screen, and the two can be referred to as touching setting Standby, host equipment 140 can refer to the equipment component in the host or host of computer equipment for realizing touch-responsive, electromagnetic type Touch screen can refer to the touch input device independently of the electromagnetic type except computer equipment, can also refer to and be installed in various calculating The touch input device of electromagnetic type on machine equipment, computer equipment here can be laptop computer, smart phone, a Personal digital assistant, media player, navigation equipment, intelligent interaction plate, E-mail receiver/send equipment, game console, plate It is any several in computer, intelligent locomotive, pilotless automobile, intelligent refrigerator, other smart home devices or these equipment The combination of kind equipment.
Magnetic board 121 contained by touch-control system 120, is the touch sensor of electromagnetic type, and the tactile signals of sensing can wrap Include the variable quantity of magnetic flux and the frequency of electromagnetic signal.Wherein, the converted quantity of magnetic flux is related to position of touch, electromagnetic signal Frequency can indicate time writer, and whether contact screen and user are to the pressure size of time writer.
When user is different to time writer (pen tip) pressure, " pressure sensor " inside time writer experiences pressure difference, According to the frequency difference for the electromagnetic signal that the pressure incuded issues.Correspondingly, the frequency for the electromagnetic signal that magnetic board 121 senses Rate would also vary from.
Touch-control processor 122 is that the touch-control of touch-control system 120 handles chip, and touch-control mentioned herein processing chip can be with It is the Master control chip (being referred to as main process task chip or central processing unit) of touch-control system 120, is also possible to touch-control system The 120 processing chips in addition added, the processing chip can be installed in electromagnetic type touch input device.
After touch-control processor 122 receives the tactile signals that magnetic board 121 is sent, tactile signals can be corresponded to and generate touch number According to touch data may include touch position data corresponding with the flux change amount, pressure sensitivity number corresponding with the frequency According to.Touch position data may include the X-coordinate and Y-coordinate of touch location；Pressure sensitivity data may include pressure value, and pressure value is not Together, the thickness of the lines finally presented on the screen also can be different.
The embodiment of the present invention, in order to solve the problems, such as that cursor is frequently shaken, touch-control processor 122 can correspond to time writer Different conditions, preset different operating mode, wherein corresponding first operating mode of the state of writing, corresponding second work of suspended state Mode.
In the course of work, touch-control processor 122 may determine that the shape body that time writer is presently in, if it is write state, The touch data of the time writer is determined according to the first operating mode；If it is suspended state, determined according to the second operating mode The touch data of the time writer；Touch precision under second operating mode is lower than the touch under first operating mode Precision.First operating mode and the second operating mode mentioned herein can be exemplified below two kinds there are many implementation:
The first, corresponding first touch resolution ratio of the first operating mode, corresponding second touch resolution ratio of the second operating mode, Second touch resolution ratio is lower than the first touch resolution ratio.After touch-control processor 122 receives sense of touch data, it can be determined that time writer The state being presently in determines the touch position of the time writer according to scheduled first touch resolution ratio if it is the state of writing Set data；If it is suspended state, the electromagnetism is determined according to the second touch resolution ratio lower than first touch resolution ratio The touch position data of pen.
After determining touch position data according to corresponding operating mode, it includes identified touching that touch-control processor 122, which generates, The touch data for touching position data after reporting to operating system 141, can be touched when time writer is in writing state with height Resolution ratio realizes fine writing, when time writer is in scheduled suspended state, reduces the touch-control reported with low touch resolution ratio The change frequency of position reduces the change frequency of cursor position, reduces the frequent shake of cursor as far as possible, avoid unnecessary money Source consumption.
It should be noted that the first touch resolution ratio and the second touch resolution ratio, similar to the display resolution of screen, table Show, the number of touch control unit in screen, the difference is that: the numerical value of the first touch resolution ratio is greater than second and touches resolution The numerical value of rate.In addition, the first touch resolution ratio mentioned herein and the second touch resolution ratio, the display screen according to contained by screen The display resolution of (associated display screen) is configured, as: the first touch resolution ratio is greater than or equal to associated display screen Resolution ratio, the second touch resolution ratio are lower than the resolution ratio of associated display screen.
Second, the first operating mode touch resolution ratio corresponding with the second operating mode is identical, can be according to identical Predetermined touch resolution ratio generates touch position data.But after generating touch position data according to predetermined touch resolution ratio, first Touch position data directly that the touch position data of generation is current as time writer under operating mode determines to include the touching The touch data for touching position data is the touch data of the time writer.
Under second operating mode, after generating touch position data, the current location and its previous position of the time writer are judged Whether the distance set is greater than preset distance value；If it does, directly current using the touch position data of generation as time writer Touch position data determines that the touch data comprising the touch position data is the touch data of the time writer, if not It is greater than, then gives up the touch position data of generation, determines the touch data of the time writer for sky, alternatively, determining comprising previous The touch data of touch position data is the touch data of the time writer.Wherein, the preset distance value is greater than or equal to institute State the distance value of adjacent touch unit under predetermined touch resolution ratio.
Here judge whether the current location of the time writer is greater than preset distance value at a distance from its prior location, it can be with Judged according to the touch position data that the touch position data being currently generated is generated with previous time, it can also be according to camera Shooting time and the motion profile of time writer of shooting judged, can also be judged by other means, herein not It repeats again.
First operating mode and the second operating mode, can also be real by other means in addition to aforementioned two kinds of implementations Existing, as long as the touch precision under the first operating mode is higher than the second operating mode, details are not described herein for specific implementation.
It in turn, can be directly to operating system after touch-control processor 122 generates touch data in order to carry out touch-responsive 141 send, and are controlled by it subsequent touch-responsive.In this way, passing through different operating modes, it is ensured that fine under writing state While writing, the change frequency of cursor position under suspended state is reduced, and then reduces the frequent shake of cursor as far as possible, is avoided Unnecessary resource consumption
In addition, in order to further save resource or reduce cursor shake, it is raw in touch-control processor 122 under each operating mode After the touch data comprising identified touch position data, may determine that the adjacent touch position data generated twice and Whether pressure sensitivity data are identical, if the two is identical, if can abandon this touch data reports any one different, then to Operating system 141 reports.
In certain examples, touch-control processor 122 is integrated on the touch-control mainboard of touch-control system 120, in operating system 141 When grasping touch data, it can be transmitted by the data line between touch-control mainboard and host equipment 140.
After operating system 141 receives touch data, received touch data can be sent to the touch contained by it and driven It is dynamic, the touch data is parsed by touching driving, to trigger the response operation of the touch data.
In addition, operating system 141 can be sent to for the touch data after parsing by touching driving in response to touch data In input subsystem (input_device).
The input subsystem can be made of device drive layer, input core layer and event handling layer, wherein device drives The hardware of bottom can be inputted and be converted into unified event form by layer, be reported to input core layer, and input core layer can be held It opens down, event is handled for the facility registration and operation interface, notification event process layer of the driving layer input of hardware.
Under certain scenes, while reducing the frequent shake of cursor as far as possible, wanting for precision is touched when time writer is write Ask also very high, and with the raising of touch accuracy, touch-control processor semaphore to be treated is increasing, at its signal It is also higher and higher to manage Capability Requirement, for the signal handling capacity of touch-control processor, needs using high performance processor, and it is high The at high cost of the processor of performance, volume are big, and the cost that will cause touch apparatus improves and volume increases.In order to solve this simultaneously Problem, designer of the invention propose another system for the processing that the touch data of the embodiment of the present invention may be implemented:

The technology contents of the present embodiment may refer to the embodiment that Figure 1A is related to, the difference is that: magnetic board 221 senses To after tactile signals, touch-control system 220 is not necessarily to being converted to tactile signals into touch signal, but transmits and touch to operating system 240 Feel signal.
Touch-control system 220 to operating system 240 transmit tactile signals when, if magnetic board 221 be have both control function and The equipment for acquiring function can directly be passed through predetermined interface to operating system such as electromagnetic type touch sensing chip from magnetic board 221 The 240 transmission tactile signals.Predetermined interface mentioned herein can be USB-bulk interface, RS232 interface or USB-hid and connect Mouth (hid is the abbreviation of Human Interface Devices, i.e. human interface device) etc., which can be logical USB-hid interface, in addition, predetermined interface is also possible to the designer of the present invention program or other equipment manufacturer makes by oneself The signal transmission interface of justice.
In other examples, touch-control system 220 can also include that touch-control handles core device 223, and touch apparatus 120 is to operating system When transmitting tactile signals, if magnetic board 221 does not have control function, core device 223 can be handled by touch-control and be read from magnetic board 221 The tactile signals are taken, then core device 223 is handled from touch-control, the touching is transmitted to transmission operating system 240 by above-mentioned predetermined interface Feel signal.The Master control chip that touch-control processing core device 223 mentioned herein can be touch-control system 220 (is referred to as main place Manage chip or central processing unit), it is also possible in addition processing chip that touch-control system 220 is added, which can install In in touch apparatus, also can be set in outside touch apparatus.
After operating system 240 receives tactile signals, tactile signals can be corresponded to and generate touch data, wherein touch data It may include touch position data corresponding with the flux change amount, pressure sensitivity data corresponding with the frequency.Touch location Data and pressure sensitivity data are as previously mentioned, details are not described herein.
The embodiment of the present invention, in order to solve the problems, such as that cursor is frequently shaken, operating system 240 can correspond to time writer not With state prewired different operating mode, wherein write corresponding first operating mode of state, corresponding second Working mould of suspended state Formula.
In the course of work, operating system 240 may determine that the shape body that time writer is presently in, and if it is the state of writing, press The touch data of the time writer is determined according to the first operating mode；If it is suspended state, institute is determined according to the second operating mode State the touch data of time writer；Touch precision under second operating mode is lower than the touch essence under first operating mode Degree.First operating mode and the second operating mode mentioned herein can be exemplified below two kinds there are many implementation:
The first, corresponding first touch resolution ratio of the first operating mode, corresponding second touch resolution ratio of the second operating mode, Second touch resolution ratio is lower than the first touch resolution ratio.After operating system 240 receives sense of touch data, it can be determined that time writer is worked as Preceding state in which determines the touch location of the time writer according to scheduled first touch resolution ratio if it is the state of writing Data；If it is suspended state, the time writer is determined according to the second touch resolution ratio lower than first touch resolution ratio Touch position data.Wherein, the first touch resolution ratio and the second touch resolution ratio such as previous embodiment, details are not described herein.
For operating system 240 after determining touch position data according to corresponding operating mode, generating includes the touch location The touch data of data.
Under certain scenes, receive tactile signals in operating system 240 is signal processing code 241, signal processing code 241 be the module on a logical meaning, touches position for being converted to received tactile signals according to different operating modes Data are set, and then generate touch signal.
When converting tactile signals, which, can be by passing through it as the module on a logical meaning Except the central processing unit (being referred to as Master control chip or main process task chip) or central processing unit of place host equipment Computer program instructions corresponding in the readable mediums such as nonvolatile memory are read into memory operation by other processing chips It is formed.The program that the processor of host equipment or other processing chips except processor can read the storage of its memory refers to It enables, and in response, tactile signals is converted into touch signal.
And after tactile signals are converted to touch signal, the subsequent identification of system for ease of operation responds the touch signal, In one example, the touch signal can be transmitted to touch apparatus by signal processing code 241.Here the touch signal is transmitted When, it can also be transmitted by above-mentioned predetermined interface.
In order to realize touch-responsive, the touch-control system 220 that touch apparatus carries may include memory and non-volatile memories Device can store the code for encoding touch signal in memory, which includes executable program instruction, is being received To after the touch signal, touch-control processor 223 can read executable program instruction to interior out of nonvolatile memory Operation is deposited, the module on logical meaning is formed, which can be referred to as Signal coding code, in response, the Signal coding Code can encode received touch signal according to the data encoding convention of standard, then be transferred to operating system again 240.It is parsed by the touch signal after 245 pairs of codings of touch driving of operating system 240.In turn, the touch letter after parsing Number it can be transmitted to input subsystem 243, by 243 Direct Recognition of input subsystem, generate corresponding touch event.Input subsystem System 243 may refer to previous embodiment, and details are not described herein.
In another example, after operating system 240 generates touch signal, the embodiment of the present invention can not also be to touch apparatus Touch signal is returned, but touch signal is otherwise transmitted to input subsystem (input_device) and is responded, If signal processing code 241 generates touch signal, send the touch signal to virtual touch equipment, virtual touch equipment according to The data encoding convention that input subsystem 243 is supported encodes received touch signal, and sends to input subsystem 243, and Input subsystem 243 responds the touch signal after the virtual touch device coding, generates corresponding touch event.
Wherein, virtual touch equipment is that have the function of touch apparatus by what software was simulated, operate in operating system 240 In virtual unit, after bringing into operation, can make a reservation for input subsystem 243 its backward input subsystem 243 transmission letter Number data encoding convention, i.e. the data encoding convention supported of input subsystem 243, the data encoding convention can be from mark The valid data coding criterion that quasi- data encoding convention extracts, is also possible to scheduled data encoding convention.
Second, the first operating mode touch resolution ratio corresponding with the second operating mode is identical, can be with identical pre- Determine touch resolution ratio and generates touch signal.But after generating touch position data according to predetermined touch resolution ratio, the first Working mould Under formula, the touch position data directly that the touch position data of generation is current as time writer of operating system 240, determination includes The touch data of the touch position data is the touch data of the time writer.
Under second operating mode, after operating system 240 generates touch position data, the current location of the time writer is judged With whether be greater than preset distance value at a distance from its prior location；If it does, directly using the touch position data of generation as electricity The current touch position data of magnetic pen determines that the touch data comprising the touch position data is the touch number of the time writer According to determining the touch data of the time writer for sky, alternatively, determining if it is not greater, then give up the touch position data of generation Touch data comprising previous touch position data is the touch data of the time writer.Wherein, the preset distance value is greater than Or the distance value equal to adjacent touch unit under the predetermined touch resolution ratio.
Here judge whether the current location of the time writer is greater than preset distance value at a distance from its prior location, it can be with Judged according to the touch position data that the touch position data being currently generated is generated with previous time, it can also be according to camera Shooting time and the motion profile of time writer of shooting judged, can also be judged by other means, herein not It repeats again.
Under certain scenes, operation of the operating system 240 under the first operating mode and the second operating mode can be by signal It handles code 241 to execute, specifically may refer to previous embodiment, details are not described herein.
After generating touch signal, operating system 240 can send touch signal to touch apparatus or virtual touch equipment, in detail Thin process may refer to the content that previous embodiment is related to, and details are not described herein.
The embodiment of the present invention can also lead to except the first operating mode and the second operating mode are in addition to aforementioned two kinds of implementations Other modes realization is crossed, as long as the touch precision under the first operating mode is higher than the second operating mode, details are not described herein.
It is implemented by above-mentioned it is found that tactile signals can be converted to touching according to different operating modes by operating system 240 Signal is touched, touch apparatus is transported in passback or virtual touch equipment carries out subsequent touch-responsive, is avoiding cursor from shaking as far as possible While, tactile signals are carried out to the conversion process of touch signal without touch apparatus, can reduce the property for controlling it chip It can require, and then in touch apparatus therefore touch apparatus can be reduced as control chip using the chip of low performance Cost and volume.
The treatment process of lower touch data is discussed in detail below in conjunction with attached drawing:
Fig. 2A is please referred to, Fig. 2A is the process of the processing method of the touch data shown in an exemplary embodiment of the invention Figure, includes the following steps S201-S203:

Step S203, if it is suspended state, the touch data of the time writer is determined according to the second operating mode；It is described Touch precision under second operating mode is lower than the touch precision under first operating mode.
Wherein it is determined that when the current state of time writer, it can be according to the touch sensor of electromagnetic type in touch-control system, such as electricity The frequency of the received electromagnetic signal of magnetic sheet is judged, in an example, can determine shape locating for time writer by following operation State:
According to the frequency for the electromagnetic signal that magnetic board senses, the current state of the time writer is determined；
If the frequency of the electromagnetic signal is in scheduled writing frequency range, it is determined that the time writer is currently at Writing state.
Under certain scenes, which it is pre- can to determine that the time writer is currently in scheduled suspension frequency range Fixed suspended state.Writing frequency range mentioned herein and suspension frequency range are determined by the configuration inside time writer, because of electricity The difference of the configuration of magnetic pen and it is different, can be arbitrary frequency values, the embodiment of the present invention is without limitation.
Under another scene, it is contemplated that when needing to write, before the hand-held time writer of user touches screen, in the of short duration time Time writer is also suspended in apart from a certain range of space of screen, and the frequency of electromagnetic signal is in scheduled suspension frequency range.And The time of suspension is shorter, occurs that a possibility that cursor is frequently shaken is lower, if within this of short duration time, according only to magnetic board The state of time writer is determined as scheduled suspended state by the frequency of received electromagnetic signal, after the of short duration time, and according to electricity The state of time writer is determined as writing state by the frequency of the received electromagnetic signal of magnetic sheet, can cause repeatedly cutting for touch resolution ratio It changes, causes the unnecessary wasting of resources.
In view of above situation, the embodiment of the present invention can continue according to the frequency of the received electromagnetic signal of magnetic board Time in scheduled suspension frequency range judges the state of time writer.If duration is greater than or equal at the first time Threshold value, it is determined that the time writer is currently at suspended state.First time threshold mentioned herein can be according to actual field Scape demand is predetermined, is such as predefined as 30ms or other numerical value.
In addition, the frequency of the received electromagnetic signal of magnetic board can determine time writer in scheduled writing frequency range In the state of writing.In addition, being lower than institute if the frequency of the electromagnetic signal continues the time in the suspension frequency range First time threshold is stated, can also determine that the time writer is currently at writing state.
In other embodiments, except the frequency according to the received electromagnetic signal of magnetic board, judge outside the state of time writer, also The state of time writer can be judged according to pre-generated pressure sensitivity data.In addition, if magnetic board itself has certain judgement Ability can also be judged the state of time writer by magnetic board according to the frequency that itself is sensed, and then inform that executing subject is sentenced Disconnected, mass center main body mentioned herein can be operating system 240 shown in touch-control processor 122 or Figure 1B shown in figure 1A.
