In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order, but rather the terms "first \ second \ third" are used to interchange specific orders or sequences, where appropriate, so as to enable the embodiments of the application described herein to be practiced in other than the order shown or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the related art, the auxiliary function of the stylus pen can be realized by the following two ways:
the first mode is a solid key and a basic key design scheme. Referring to fig. 1, through steps S101 to S105, key values may be uploaded to a host system (i.e., an electronic device operated by a stylus) through a pen protocol or bluetooth, so as to implement various key functions.
However, this method has the following disadvantages: the pen body shell needs to be dug, the design of a closed integrated pen body cannot be realized, and the appearance is not good; the keycaps, the key supports and the key materials are added, the assembly steps are increased, and the cost is increased; the PCBA board needs to reserve a key space, and the PCBA board frame needs to be large; if the waterproof rubber mat is not added, the waterproof rubber mat cannot be used for waterproofing, and the cost is higher due to the addition of the waterproof rubber mat; the key position is near the hand holding position, so that the error touch is easy to occur; the hand feeling of the key is affected as the number of times of use increases.
And in the second mode, the design scheme of the touch film and the pen body shell without digging holes is adopted. Referring to fig. 2, key values are uploaded to the host system through bluetooth through steps S201 to S204, so as to implement functions such as double-click wake-up or eraser switching.
However, this method has the following disadvantages: the whole set of materials of the touch control film is added, the assembly steps are increased, and the cost is high; the touch film is required to be tightly attached to the inner wall of the pen body, and the material of the pen body is limited and cannot be a metal material with a signal shielding effect; the touch control film needs to be tightly attached to the inner wall of the pen body, the coverage area is large, false touch is easy to occur, and key values capable of being output are few in order to avoid false touch; in order to handle touch reporting while holding, the power consumption brought by the touch film is large.
Based on the problems in the related art, the embodiments of the present application provide a control method, which can be applied to a stylus pen, and the method provided in the embodiments can be implemented by a computer program, and when the computer program is executed, each step in the control method provided in the embodiments is completed. In some embodiments, the computer program may control a processor in the stylus to execute. Fig. 3 is a schematic flow chart of an implementation of a control method provided in an embodiment of the present application, and as shown in fig. 3, the control method includes:
step S301, in response to the acquired predetermined instruction, controlling the stylus to enter a first mode.
Here, the stylus may be a capacitive stylus or an electromagnetic stylus; the touch control pen is also connected with the electronic device in a communication mode, and the electronic device connected with the touch control pen in the communication mode can be operated, such as writing on the electronic device or remotely controlling page turning, power off and the like of a display interface of the electronic device.
In the embodiment of the present application, a gesture sensor is disposed in the stylus pen, and the gesture sensor can recognize a motion track in any direction, for example, the gesture sensor may be a six-axis sensor, wherein the gesture sensor may be composed of three accelerometers and three gyroscopes.
In practical implementation, the starting state of the stylus is an initialization state, and in the initialization state, if pose change data is detected by the pose sensor, a predetermined instruction is obtained, where the pose change data is used to represent data indicating that the pose of the stylus changes, for example, when the stylus is held up or moved, the pose sensor generates pose change data; and then, responding to the acquired preset instruction by controlling the stylus to switch from the initialization state to the first mode, wherein when the stylus is in the first mode, the stylus can identify the motion track of the stylus as a gesture command based on the gesture sensor.
In the embodiment of the present application, the gesture command is a command for switching an operating mode of the stylus, where the operating mode of the stylus may include a first mode, a second mode, and a third mode, and based on this, the stylus is capable of switching the stylus from the first mode to the second mode or the third mode based on the gesture command.
In step S302, when the gesture sensor recognizes a first gesture command in the first mode, the stylus is controlled to switch from the first mode to the second mode.
Here, the first gesture command may be a default gesture command, and the gesture command may also be a custom gesture command; for example, the first gesture command may be a command formed by a stylus pen clockwise scribing a first specific track, the first specific track may be a circle with a radius larger than a first radius threshold, and the first specific track may also be a square with a side length larger than a first side length threshold.
In the embodiment of the application, if the stylus is in the first mode and the gesture sensor further recognizes the first gesture command, the stylus is controlled to be switched from the first mode to the second mode, so that mode switching of the stylus is realized. When the touch pen is in the second mode, the touch pen can identify the motion track of the touch pen as the position coordinate based on the attitude sensor.
In practical implementation, the second mode may be an air mouse mode, that is, in the second mode, the stylus pen may move or manipulate a cursor in the display screen of the electronic device through its own motion track.
In some embodiments, when the stylus is in the second mode, the stylus constructs a motion coordinate system, obtains a motion track of the stylus through the attitude sensor, and converts the motion track into position coordinates by combining the motion coordinate system; then, the touch control pen sends the position coordinates to the manipulated electronic equipment through the established communication connection, so that the electronic equipment moves a cursor in the display screen of the electronic equipment based on the position coordinates, and the function of the air mouse is realized.
In the embodiment of the present application, through the above steps S301 and S302, when the stylus receives a predetermined instruction of being held, picked up, or moved, the stylus is controlled to enter the first mode to respond to the predetermined instruction, where in the first mode, the stylus can recognize its own motion trajectory as a gesture command based on its own posture sensor; then, if the gesture sensor identifies a first gesture command in the first mode, controlling the stylus to switch from the first mode to a second mode, wherein in the second mode, the stylus can identify the motion track of the stylus as the position coordinate based on the gesture sensor; finally, the stylus also sends the position coordinates to the manipulated electronic device, so that the electronic device moves the cursor in its display screen based on the position coordinates. Therefore, mode switching can be realized based on the motion track detected by the attitude sensor, misoperation is reduced, and convenience in operation is improved. In addition, because the gesture sensor is slightly interfered by the external environment, the touch pen can always keep high sensitivity in the using process.
In some embodiments, as shown in fig. 4, the step S301 "controlling the stylus to enter the first mode in response to the obtained predetermined instruction" may be implemented by:
in step S3011, it is determined whether the stylus is in an initialization state.
Here, the initialization state refers to a configuration in which all the setting data in the stylus pen are restored to factory, and in actual implementation, the step S3011 may be implemented in three ways:
the first method is as follows: and acquiring firmware information of the stylus, and determining that the stylus is in an initialization state if the firmware information represents that the firmware of the stylus is in an initialization mode.
Here, the firmware information of the stylus may be periodically or in real time acquired from the memory, and if the firmware information is factory information set by the firmware when the firmware is shipped, the firmware information may represent that the firmware of the stylus is in an initialization mode. Meanwhile, if the firmware information is not factory information set when the firmware is factory, the firmware information represents that the firmware of the stylus is not in the initialization mode, and based on the firmware information, the stylus is not in the initialization state.
The second method comprises the following steps: and acquiring the state information of a charging module in the stylus, and determining that the stylus is in an initialization state if the state information represents that the stylus is in a charging state.
For example, the state information of the charging module may be 0 and 1, where 0 is the corresponding state information when the charging module is not connected to the external power source, and 1 is the corresponding state information when the charging module is connected to the external power source. Based on this, the state information of the charging module can be acquired periodically or in real time, if the state information of the charging module is 1, the charging module is characterized to be connected with an external power supply, the touch pen can be charged through the external power supply, and at this time, the touch pen is determined to be in an initialization state. And if the state information of the charging module is 0, the charging module is not connected with an external power supply, the touch pen is not charged, and at the moment, the touch pen is determined not to be in an initialization state.
The third method comprises the following steps: and acquiring induction information of the induction control in the stylus, and determining that the stylus is in an initialization state if the induction information represents that the position relationship between the stylus and the matching device meets a preset relationship.
Here, the matching device may be a pen slot, a charging seat, or a charging device, and when the stylus contacts the matching device, the touch control generates sensing information through the sensing control, and at this time, it is determined that the positional relationship between the stylus and the matching device satisfies a predetermined relationship, and based on this, it is determined that the stylus is in an initialization state. When the touch control pen is not in contact with the matching device, the sensing control cannot generate sensing information, the position relation between the touch control pen and the matching device is considered not to meet the preset relation, and the touch control pen is determined not to be in an initialization state.
In the embodiment of the present application, if it is determined that the stylus pen is in the initialization state, step S3012 is performed; if the stylus pen is not in the initialization state, the process proceeds to step S3014.
Step S3012, a predetermined instruction is generated based on the detected posture change data of the posture sensor.
At this time, the stylus is in an initialized state, the attitude sensor of the stylus detects pose change data in real time, and when the pose change data is detected, a predetermined instruction is generated based on the pose change data, wherein the predetermined instruction is a state switching instruction, and the stylus can be switched from the initialized state to other states based on the predetermined instruction.
In step S3013, control switches the stylus from the initialization state to the first mode.
Here, the stylus may be switched from the initialization state to the first mode based on a predetermined instruction, so as to achieve the purpose of changing the state of the stylus by the predetermined instruction.
Step S3014, determine the current mode of the stylus, and generate a mode prompt message.
Here, the current mode of the stylus may be obtained through the state reading instruction, and a mode prompt message may be generated based on the current mode. The mode prompting message may be a character type message, and the mode prompting message may also be a sound type message.
Step S3015, send the mode prompting message to the electronic device operated by the stylus, so that the electronic device obtains the current mode of the stylus.
Here, the stylus transmits a mode prompting message to the electronic device through the established communication connection, so that the electronic device can know a current mode of the stylus, wherein the electronic device is in communication with the stylus, and meanwhile, the stylus can operate the electronic device through the established communication connection, for example, the stylus writes, clicks and the like on the electronic device; then, the electronic device can also output the mode prompt message, and when the mode prompt message is actually output, the mode prompt message of a character type can be output through a display screen of the electronic device, and the mode prompt message of a sound type can also be output through a buzzer of the electronic device.
In this embodiment of the application, through the steps S3011 to S3015, when the stylus is determined to be in the initialization state, if the gesture sensor further detects pose change data, a predetermined instruction is generated based on the pose change data to control the stylus to switch from the initialization state to the first mode; and if the attitude sensor does not detect the pose change data, keeping the current initialization state. Then, the current mode of the touch pen can be obtained, and a mode prompt message is generated; and finally, sending the mode prompt message to the electronic equipment controlled by the touch pen, so that the electronic equipment obtains the current mode of the touch pen, the information intercommunication between the touch pen and the electronic equipment is enhanced, and the cooperation of the touch pen and the electronic equipment is improved. Therefore, mode switching can be achieved through the touch posture change, the mode switching process is simplified, and convenience of mode switching is improved. In addition, whether the touch pen is in an initialization state can be judged in multiple modes, and robustness of the touch pen is improved.
In some embodiments, as shown in fig. 5, after the step S301 "controlling the stylus to enter the first mode in response to the obtained predetermined instruction" is performed, the following steps may be further performed:
step S302' judges whether the attitude sensor recognizes the first gesture command.
Here, the motion trajectory recognized by the gesture sensor may be obtained first, and then, whether the motion trajectory is the same as the first specific trajectory corresponding to the first gesture command is determined through a comparison method, if the motion trajectory is the same as the first specific trajectory corresponding to the first gesture command, the gesture sensor is characterized to recognize the first gesture command, and the process proceeds to step S303'. If the motion trajectory is not the same as the first specific trajectory corresponding to the first gesture command, the gesture sensor does not recognize the first gesture command, and the process proceeds to step S304'.
In this embodiment of the application, the first gesture command may be a default gesture command, and the gesture instruction may also be a custom gesture command; for example, the first gesture command may be a command formed by a stylus pen clockwise scribing a first specific track, the first specific track may be a circle with a radius larger than a first radius threshold, and the first specific track may also be a square with a side length larger than a first side length threshold.
In step S303', the stylus is controlled to switch from the first mode to the second mode.
At this time, the motion track is the same as the first specific track corresponding to the first gesture command, and the gesture sensor recognizes the first gesture command, and then the stylus is controlled to switch from the first mode to the second mode based on the first gesture command. The second mode may be an air mouse mode, that is, in the second mode, the stylus may move or manipulate a cursor in the display screen of the electronic device through its own motion track.
And step S304', judging whether the motion trail meets the preset condition.
At this time, the motion track is not the same as the first specific track corresponding to the first gesture command, and if the first gesture command is not recognized by the representation attitude sensor, whether the motion track meets the predetermined condition is continuously judged.
Here, the predetermined condition may be a specific character track, and exemplarily, the predetermined condition may be a C track, a W track, an M track, or the like. In the embodiment of the present application, whether the motion trajectory meets the predetermined condition may be determined by a comparison method, and if the motion trajectory meets the predetermined condition, the step S305' is performed; and if the motion trajectory does not satisfy the predetermined condition, the process proceeds to step S307'.
In step S305', the motion trajectory is encapsulated to obtain encapsulation trajectory information.
At the moment, if the motion trail meets the preset condition, the motion trail is cut and edited to realize the packet processing of the motion trail, and packet trail information is obtained.
Step S306', the packet track information is sent to the electronic device operated by the stylus pen, so that the electronic device determines and responds to the gesture command corresponding to the packet track information.
Here, the stylus pen transmits the packet track information to the manipulated electronic device, which may be a computer, a mobile phone, a television, etc., through the established communication connection, so that the electronic device determines and responds to the gesture command corresponding to the packet track information.
In actual implementation, after receiving the packet track information, the electronic device determines a gesture instruction corresponding to the packet track information, for example, a screen clearing instruction corresponding to the C track; and then responds to the gesture command. For example, when the electronic device determines that the gesture command corresponding to the packet information is a screen clearing command, the electronic device may clear the content displayed on the display screen of the electronic device based on the screen clearing command.
In some embodiments, when it is determined that the motion trajectory satisfies the predetermined condition, the stylus may further directly generate a corresponding gesture instruction based on the motion trajectory, for example, generate a screen clearing instruction based on the C trajectory; then, the gesture instruction is sent to the electronic device, so that the electronic device executes a corresponding operation based on the gesture instruction, for example, after the electronic device receives the screen clearing instruction, the electronic device executes an operation of clearing the display content of the display screen based on the screen clearing instruction.
In this application embodiment, no matter determine the gesture instruction through electronic equipment or determine the gesture instruction through the touch-control pen, the touch-control pen all can realize the control to electronic equipment through the movement track, promotes the convenience of control, improves control efficiency.
Step S307' determines whether the gesture sensor recognizes the second gesture command.
At this time, if the gesture sensor does not recognize the first gesture command and the motion trajectory does not meet the predetermined condition, continuing to judge whether the motion trajectory is a second specific trajectory corresponding to the second gesture command by using a comparison method, and if the motion trajectory is the second specific trajectory corresponding to the second gesture command and the characterization sensor recognizes the second gesture command, entering step S308'; and if the motion track is not the second specific track corresponding to the second gesture command, the gesture sensor does not recognize the second gesture command, and the step returns to step S302'.
In this embodiment of the application, the second gesture command may be a default gesture command, and the gesture instruction may also be a custom gesture command; for example, the second gesture command may be a command formed by the stylus drawing a second specific track counterclockwise, the second specific track may be a circle with a radius larger than a second radius threshold, and the second specific track may also be a square with a side length larger than a second side length threshold.
In step S308', the stylus is controlled to switch from the first mode to the third mode.
At this time, the motion track is a second specific track gesture corresponding to the second gesture command, and if the characterization sensor recognizes the second gesture command, the stylus is controlled to switch from the first mode to the third mode based on the second gesture command. The third mode may be a writing mode of the stylus pen, and the stylus pen can recognize the gravity center change information of the stylus pen in the third mode.
Step S309', in response to the motion trajectory generated by the stylus touch on the electronic device manipulated by the stylus, generating a corresponding motion trajectory on the display screen of the electronic device.
Here, since the stylus pen can recognize the gravity center change information of itself in the third mode without recognizing the gesture command, the power consumption of the third mode is less than that of the second mode.
In this application embodiment, the stylus can generate a corresponding movement track by acting on the display screen of the electronic device, and also can send the movement track to the electronic device, so that the movement track is displayed through the display screen of the electronic device, and the writing function of the stylus is realized.
In the embodiment of the present application, through the steps S302 'to S309', the motion trajectory of the stylus is first obtained through the attitude sensor, and then whether to perform mode switching is determined based on the motion trajectory, and if the mode switching is performed, which mode the stylus is switched from the initialization state to is also determined; in addition, after the mode switching is completed, the touch pen realizes the function corresponding to the switched mode, so that convenient and efficient mode switching is realized, misoperation can be avoided, and the switching accuracy is improved.
In some embodiments, to achieve flexibility of mode switching and energy saving, as shown in fig. 6A and 6B, after "determining the current mode of the stylus pen" in step S3014, the following steps may be further performed:
step S3015', it is determined whether the current mode is one of the first mode, the second mode, and the third mode.
Here, it is determined whether the current mode is one of the first mode, the second mode and the third mode by the comparison method, referring to fig. 6A, if the current mode is one of the first mode, the second mode and the third mode, step S3016A' is entered. If the current mode is not one of the first mode, the second mode, and the third mode, the process returns to step S3014.
Step S3016A', obtain the status information of the charging module in the stylus pen.
At this time, the current mode is one of the first mode, the second mode and the third mode, and then the state information of the charging module is obtained, where the implementation process of step S3016A 'is similar to the implementation process of the second mode in step S3011, and therefore, the implementation process of step S3016A' may refer to the implementation process of the second mode in step S3011.
Step S3017A', determine whether the status information indicates that the stylus is in the charging status.
Here, the implementation procedure of step S3017A 'is similar to the implementation procedure of mode two in step S3011, and therefore, the implementation procedure of step S3017A' may refer to the implementation procedure of mode two in step S3011.
In this embodiment of the application, if the state information indicates that the stylus is in the charging state, step S3018A'; if the state information indicates that the stylus pen is not in the charging state, the process returns to step S3016A'.
Step S3018A', the current mode is switched to the initialization state.
At this time, the state information represents that the stylus is in the charging state, and the current mode of the stylus is switched to the initialization state.
In this embodiment of the application, through the above steps S3015 'to S3018A', the current mode is one of the first mode, the second mode, and the third mode, the state information of the charging module is continuously obtained, and if the state information of the charging module indicates that the stylus is in the charging state, the stylus is switched to the initialization state, so that initialization of the stylus is achieved through a simple operation, so as to prepare for subsequent work.
In other embodiments, referring to fig. 6B, when implementing step S3015 '″ of determining whether the current mode is one of the first mode, the second mode, and the third mode, "if the current mode is one of the first mode, the second mode, and the third mode, step S3016B' may be further entered. If the current mode is not one of the first mode, the second mode, and the third mode, the process returns to step S3014.
Step S3016B', obtaining the standing time of the stylus by using the attitude sensor.
The gesture sensor also has a timing function, if the gesture sensor detects that the touch pen is static, timing is started until the touch pen moves or shakes, a timing result is obtained, and the timing result is the standing time length. The timing result can represent the duration of the stylus in standing.
Step S3017B', it is determined whether the standing time period is greater than the time period threshold value.
Here, the duration threshold may be a default value or a custom value, and may be, for example, 10 seconds, 11 seconds, 12 seconds, or the like.
In this embodiment of the application, the size relationship between the standing time and the time threshold may be determined by a size comparison method, and if the standing time is greater than the time threshold, it is indicated that the stylus does not move or shake for a long time, that is, the stylus does not operate the electronic device for a long time, the process proceeds to step S3018B'; and if the standing time length is less than or equal to the time length threshold value, which indicates that the stylus normally operates the electronic device, returning to step S3016B'.
In step S3018B', the mode of the stylus is switched to the sleep mode.
At this time, the standing time is longer than the time threshold, which indicates that the stylus does not move or shake for a long time, that is, the stylus does not operate the electronic device for a long time, and in order to save energy consumption, the mode of the stylus is switched to the sleep mode with lower power consumption.
In the embodiment of the application, the attitude sensor can identify the gravity center change information of the attitude sensor in the sleep mode. That is, whether the stylus is moved or shaken can be detected through the gravity center change information by the posture sensor.
Step S3019B' determines whether the attitude sensor recognizes the center of gravity change information.
Here, the information obtained by the sensor may be analyzed to obtain an analysis result. If the analysis result includes the gravity center change information, it is determined that the attitude sensor recognizes the gravity center change information, and the process proceeds to step S3020B'; if the center of gravity change information is not included in the analysis result, it is determined that the attitude sensor does not recognize the center of gravity change information, and the process proceeds to step S3021B'.
Step S3020B' returns the stylus from the sleep mode to the current mode.
At this time, the attitude sensor recognizes the gravity center change information, and represents that the stylus is moving or jittering, and then returns the stylus from the sleep mode to the current mode. The current mode is the current mode in step S3015', that is, the current mode is the mode of the stylus before switching to the sleep mode.
Step S3021B' maintains the sleep mode of the stylus.
At this time, the gravity center change information is not recognized by the attitude sensor, and the stylus is still kept still, so that the stylus is kept in the sleep mode.
In this embodiment, through the steps S3016B 'to S3021B', when the current mode of the stylus is one of the first mode, the second mode, and the third mode, the standing duration of the stylus is obtained, and if the standing duration is greater than a threshold value, the stylus is switched to the sleep mode; then, if the gravity center change information of the stylus is detected in the sleep mode, the stylus is returned to the current mode from the sleep mode, and the corresponding operation is executed again. Therefore, the power consumption of the touch control pen can be reduced on the premise of not influencing the normal work of the touch control pen, the energy is saved, and the service life of the touch control pen is prolonged.
