[0056] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0057] In some possible embodiments, in the event of the stylus pen being put down and the event of the pen being lifted, that is, when the stylus pen contacts the screen of the electronic device and leaves the screen of the electronic device, the stylus pen sends pen tip data to the electronic device via near field communication or Bluetooth communication. However, due to the limitation of the transmission bandwidth of near field communication, when the pen tip data is transmitted via near field communication, the pressure sensing data received by the electronic device has low accuracy due to the inability to transmit a large amount of data, thereby affecting the sensitivity of the stylus pen; due to the limitation of the transmission delay of Bluetooth communication, when the pen tip data is transmitted via Bluetooth communication, the electronic device cannot display the handwriting in time or stop displaying the handwriting in time due to the inability to receive the pen tip data in time, resulting in the problem of display lag when writing down and the problem of handwriting tailing when lifting the pen, thereby affecting the user experience of the stylus pen.

[0058] In an exemplary embodiment of the present disclosure, in order to overcome the technical problems existing in the related art, a handwriting processing method is provided, which is applied to an electronic device, including: receiving first information sent by a stylus, the first information is used to indicate that the stylus is in a suspended state or a contact state; determining first pressure sensing data according to the first information; and performing handwriting processing according to the first pressure sensing data. The method in the embodiment of the present disclosure can display the handwriting in time when the stylus switches from a suspended state to a contact state, and stop displaying the handwriting in time when the stylus switches from a contact state to a suspended state, so that the display of the handwriting responds to the operation of the stylus in time, thereby improving the user experience.

[0059] In the exemplary embodiments of the present disclosure, the electronic device is an electronic device that can support the handwriting function of a stylus, including but not limited to a tablet computer, a smart phone, a computer device, a handwriting board, and a drawing board. The stylus can also be called a touch pen, including but not limited to a resistive stylus and an inductive stylus. Figure 1 The figure is a schematic diagram of a scene when a stylus pen is used for inputting on an electronic device according to an exemplary embodiment.

[0060] In an exemplary embodiment of the present disclosure, a handwriting processing method is provided, which is applied to an electronic device. Figure 2 is a flow chart of a handwriting processing method according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0061] Step S201: receiving first information sent by a stylus pen, where the first information is used to indicate that the stylus pen is in a suspended state or a contact state.

[0062] The suspended state means that there is no contact between the pen tip and the electronic device screen, and the stylus in the suspended state cannot be used for writing and drawing input in the electronic device. The contact state means that the pen tip is in contact with the electronic device screen, and the stylus in the contact state can be used for writing and drawing input in the electronic device.

[0063] In some possible implementations, the suspended state and the contact state are calculated based on the data collected by the pressure sensor located at the tip of the pen. For example, when the value of the data collected by the pressure sensor is 0, it is determined to be a suspended state, otherwise it is determined to be a contact state. For another example, when the data collected by the pressure sensor is less than a threshold, it is determined to be a suspended state, otherwise it is determined to be a contact state.

[0064] In some possible implementations, the hovering state indicates that the distance between the pen tip and the electronic device screen is greater than 0, and the contact state indicates that the distance between the pen tip and the electronic device screen is equal to 0.

[0065] In some possible implementations, the suspended state indicates that the distance between the pen tip and the electronic device screen is greater than a set value, and the contact state indicates that the distance between the pen tip and the electronic device screen is less than a set value. The set value is a value within the communication range for transmitting the first information. For example, when the stylus pen sends the first information to the electronic device using near field communication, the communication range of the near field communication is within 10 centimeters, and the set value is a value within 10 centimeters.

[0066] The first information only includes the state information of the stylus, and there are only two states: the hovering state and the contact state. When defining the first information in the communication protocol between the stylus and the electronic device, for example, the identifier "Hover" and the identifier "Ink" can be used to represent the hovering state and the contact state respectively, or the identifier "0" and the identifier "1" can be used to represent the hovering state and the contact state respectively. When the electronic device receives the first information sent by the stylus, the state of the stylus can be determined according to the communication protocol. Since the bandwidth required by the identifier in the first information is relatively small, when the stylus sends the first information to the electronic device, a wireless communication method with low transmission delay is used to transmit the first information to improve the response speed of the electronic device, such as using near field communication to transmit the first information.

[0067] Step S202: determining first pressure sensing data according to the first information.

[0068] Pressure data indicates the pressure value applied to the pen tip when using a stylus for input, and can also be called pressure value. The larger the amount of pressure data, the higher the accuracy, and the higher the sensitivity when displaying handwriting in electronic devices. Electronic devices display handwriting based on pressure data. The greater the pressure value, the thicker and more obvious the handwriting. In order to avoid accidental touches, a minimum pressure value that can just display the handwriting is usually set.

[0069] Optionally, the minimum pressure value is the minimum pressure value supported by an operating system (eg, Android system) of the electronic device.

[0070] The first pressure sensing data is a preset value. The pen-down event and the pen-lifting event, that is, the pen tip touching the screen and the pen tip leaving the screen, are determined based on the first information. Different events correspond to different first pressure sensing data.

[0071] Figure 3 is a schematic diagram showing a pen-down event and a pen-up event according to an exemplary embodiment. Figure 3 As shown, when it is determined according to the first information that the stylus is switched from a suspended state to a contact state, a stylus pen-down event is determined to have occurred. At this time, handwriting should begin to be displayed on the screen of the electronic device. Therefore, the first pressure data is greater than 0 or greater than the minimum pressure value.

[0072] like Figure 3 As shown, when it is determined according to the first information that the stylus pen switches from the contact state to the suspended state, a stylus pen lift event is determined to occur. At this time, the handwriting should stop being displayed on the screen of the electronic device. Therefore, the first pressure sensitivity data is equal to 0 or less than the minimum pressure value.

[0073] Step S203, performing handwriting processing according to the first pressure sensing data.

[0074] The pen-lifting event corresponds to the first pressure data being equal to 0. After the pen-lifting event is determined to have occurred, the handwriting completely disappears, so that the user can see the pen-stopping effect when the pen is lifted, without seeing the pen dragging phenomenon;

[0075] The pen-lifting event corresponds to the first pressure data being less than the minimum pressure value. After the pen-lifting event is determined to have occurred, the effect of handwriting disappearing is clearly displayed, so that the user can see the pen-stopping effect when the pen is lifted, without seeing the pen dragging phenomenon;

[0076] The pen-down event corresponds to the first pressure data being greater than 0 or greater than the minimum pressure value, and the handwriting can be displayed in time when the stylus is switched from a suspended state to a contact state.

[0077] In an exemplary embodiment of the present disclosure, since the stylus adopts a communication method with low transmission delay to send the first information, the first information received by the electronic device is consistent with the actual state of the stylus. According to the first information, the first pressure sensing data is determined, and the handwriting can be displayed in time when the pen is put down and the handwriting can be stopped from being displayed in time when the pen is lifted, so that the display of the handwriting responds to the operation of the stylus in time, overcoming the problem of display lag when the pen is put down and the problem of handwriting tailing when the pen is lifted.

[0078] In an exemplary embodiment of the present disclosure, a handwriting processing method is provided, which is applied to an electronic device. Figure 4 is a flow chart of a handwriting processing method according to an exemplary embodiment. Figure 4 As shown, the following steps are included:

[0079] Step S401: receiving first information sent by a stylus pen, where the first information is used to indicate that the stylus pen is in a suspended state or a contact state.

[0080] The specific implementation of step S401 refers to step S201 and will not be described in detail here.

[0081] In some possible implementations, the first information sent by the stylus is received through a first wireless connection.

[0082] Step S402: determining first pressure sensing data according to the first information within a first time period after the stylus is switched from the hovering state to the contact state and no second information sent by the stylus is received.

[0083] In some possible implementations, the second information sent by the stylus is received through a second wireless connection.

[0084] The second information is the second pressure data, which is the real-time pressure data acting on the stylus tip. In order to obtain high-precision pressure data, the second information has a large amount of data and usually has a high transmission delay. The first duration is a relatively short duration, such as 1 millisecond, 2 milliseconds, 5 milliseconds, etc.

[0085] In some possible implementations, the data transmission delay of the first wireless connection is lower than the data transmission delay of the second wireless connection, and the unit data transmission volume of the first wireless connection is higher than the unit data transmission volume of the second wireless connection.

[0086] In one example, the first wireless connection is a near field communication connection, and the type of the second wireless connection is a Bluetooth connection.

[0087] In one example, Figure 5 is a flow chart of a pen-down event and a pen-up event according to an exemplary embodiment. Figure 5 As shown, the stylus sends the pen tip pressure (i.e., pressure value) to the electronic device via Bluetooth connection, and sends the hovering / contact state to the electronic device via near field communication. When it is determined that the pen tip is in contact, and the current pressure value is 0 according to the pen tip pressure, it is still determined that a pen down event has occurred; when it is determined that the pen tip is hovering, and the current pressure value is not 0 according to the pen tip pressure, it is still determined that a pen lift event has occurred.

[0088] When the tip of the stylus touches the screen, the stylus starts to send first information and second information to the electronic device. The transmission delay of the first information is low, and the transmission delay of the second information is high. When the electronic device determines that the stylus switches from a suspended state to a contact state based on the first information, the second information cannot be received. Therefore, in order to avoid handwriting display delay, it is necessary to determine the first pressure sensing data within the first time length so as to start displaying the handwriting in time.

[0089] When determining the first pressure sensing data, one of the following two methods is used:

[0090] In the first type, the first pressure sensing data is a pressure sensing value.

[0091] The pressure sensitivity value is a preset value, and can be any pressure sensitivity value that can display handwriting. However, considering that the pressure sensitivity is usually small when writing in actual use, the first pressure sensitivity data should be a smaller pressure sensitivity value.

[0092] In some possible implementations, a pressure sensitivity value is one of the following:

[0093] The minimum pressure sensitivity value supported by the electronic device;

[0094] the product of the minimum pressure sensitivity value supported by the electronic device and the first coefficient, where the first coefficient is greater than 1;

[0095] The average pressure value calculated during the historical period;

[0096] The product of the average pressure value calculated in the historical period and the second coefficient, the second coefficient is less than 1.

[0097] Among them, the minimum pressure sensitivity value represents the minimum pressure sensitivity value that can display handwriting on the screen of the electronic device, the historical period is any period of time when handwriting is used for input before the current input using the stylus pen, and the first coefficient and the second coefficient are preset values.

[0098] Second, the first pressure sensitivity data is a plurality of pressure sensitivity values.

[0099] In some possible implementations, the multiple pressure sensitivity values ​​follow an increasing rule, and the increasing method of the increasing rule is linear increasing or non-linear increasing.

[0100] Multiple pressure sensitivity values ​​follow an increasing rule, which can simulate handwriting that is more consistent with a real writing event.

[0101] Step S403: drawing handwriting according to the first pressure sensing data until receiving second information sent by the stylus.

[0102] When the first pressure sensitivity data is a pressure sensitivity value, before receiving the second information sent by the stylus, the handwriting is drawn with the same pressure sensitivity value, and the thickness of the handwriting does not change.

[0103] When the first pressure sensitivity data is multiple pressure sensitivity values, before receiving the second information sent by the stylus, the handwriting is drawn in ascending order using the multiple pressure sensitivity values ​​in sequence, and the handwriting gradually becomes thicker and more obvious to simulate handwriting that is more consistent with a real writing event.

[0104] In some possible implementations, when the handwriting is drawn using the pressure sensitivity values ​​of the plurality of pressure sensitivity values ​​in sequence, the handwriting is drawn in one of the following three ways:

[0105] The duration of drawing strokes with different pressure sensitivity values ​​is the same;

[0106] The duration of drawing handwriting using different pressure sensitivity values ​​gradually increases;

[0107] The duration of drawing handwriting using different pressure sensitivity values ​​gradually decreases.

[0108] In one example, the end time of the first time duration after the stylus is switched from the hovering state to the contact state is determined according to the first information, and the time duration from the second time duration sent by the stylus is received is t seconds, and the first pressure sensitivity data is three increasing pressure sensitivity values ​​p1, p2, and p3, and the handwriting is drawn in one of the following three ways:

[0109] Use pressure value p1 to draw for t / 3 seconds, use pressure value p1 to draw for t / 3 seconds, use pressure value p1 to draw for t / 3 seconds;

[0110] Use pressure value p1 to draw t / 5 seconds, use pressure value p1 to draw 3t / 10 seconds, use pressure value p1 to draw t / 2 seconds;

[0111] Use pressure value p1 to draw t / 2 seconds, use pressure value p1 to draw 3t / 10 seconds, and use pressure value p1 to draw t / 5 seconds.

[0112] Step S404: the first information indicates that the stylus is in contact state, and after receiving the second pressure sensing data sent by the stylus, drawing handwriting according to the second pressure sensing data sent by the stylus.

[0113] When the stylus is in contact state, it indicates that the stylus is in a stable input state, and the handwriting is changed in real time according to the change of the second pressure data. The greater the pressure value of the second pressure data, the thicker and more obvious the handwriting is, and vice versa, the thinner and more obvious the handwriting is.

[0114] Step S405: after determining according to the first information that the stylus is switched from the contact state to the hovering state, determine that the first pressure sense data is a pressure sense value greater than or equal to 0 and less than a threshold.

[0115] When the tip of the stylus leaves the screen, the stylus sends the first information to the electronic device, switches from the contact state to the suspended state, and stops sending the second information to the electronic device. However, the transmission delay of the first information is low, and the transmission delay of the second information is high. When the electronic device determines that the stylus has switched from the contact state to the suspended state based on the first information, it has not yet received the second information synchronized with the switch to the suspended state. In order to prevent the electronic device from continuing to display the handwriting based on the second information sent last time after the user lifts the pen, at this time, the first pressure data is determined to be 0, or the first pressure data is determined to be a pressure value greater than 0 and less than the threshold, so as to stop displaying the handwriting in time. The threshold is the minimum pressure value that can display the handwriting on the screen of the electronic device.

[0116] Step S406, performing handwriting processing according to the first pressure sensing data.

[0117] In some possible implementations, handwriting drawing is not performed.

[0118] In some possible implementations, handwriting drawing is performed according to a pressure value that is greater than or equal to 0 and less than a threshold.

[0119] In both of the above methods, users will see obvious stop-writing effects.

[0120] In this embodiment, steps S401-S403 can be used as independent embodiments to implement the handwriting processing method when the stylus is put down, steps S401 and S404 can be used as independent embodiments to implement the handwriting processing method during the stylus input process, and steps S401 and S405-S406 can be used as independent embodiments to implement the handwriting processing method when the stylus is lifted.

[0121] In an exemplary embodiment of the present disclosure, the first information is received using a wireless connection with a low transmission delay, the second information is transmitted using a wireless connection with a high unit data transmission rate, and the handwriting is displayed or stopped in time in combination with the first pressure sensing data. This can ensure the accuracy of the pressure sensing data and the sensitivity of the stylus, while making the display of the handwriting respond to the operation of the stylus in time, producing a pen-down effect in time when writing, and a pen-lifting effect in time when lifting the pen, thereby improving the user experience.

[0122] In an exemplary embodiment of the present disclosure, a handwriting processing device is provided, which is applied to an electronic device. Figure 6 is a block diagram of a handwriting processing device according to an exemplary embodiment. Figure 6 As shown, including:
