Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Please refer to FIG. 2 , which is a flowchart of a method for processing input data of a tablet according to a first embodiment of the present application. The input data processing method is applied to an electronic device having the tablet. More specifically, the input data processing method is applied to a tablet system of the electronic device. It should be noted that the input data processing method of the embodiment of the present application is not limited to the steps and the sequence in the flowchart shown in FIG. 2 . The steps in the illustrated flow diagrams can be added, removed, or changed in order, depending on the requirements.

As shown in FIG. 2, the input data processing method includes the following steps:

Step 101: Acquire input data generated on the tablet according to a preset time interval.

In the embodiment, the input data includes an X coordinate value, a Y coordinate value, a pressure value, and a time stamp.

The input data may be position data of the stylus on the tablet (ie, cursor position data), or the input data may be a pressure value generated by the cursor position data and the writing operation input by the stylus on the tablet. The sum of the data, wherein the sum of the cursor position data and the pressure value data constitutes written data.

For example, when the pen is written, a writing point is generated on the tablet, and a pressure value is detected on the tablet, and the acquired input data includes cursor position data (ie, X coordinate value, Y coordinate value). And pressure value data. When the pen is lifted, no writing point is generated on the tablet, and no pressure value is detected on the tablet, and the acquired input data includes only the cursor position data (ie, the X coordinate value and the Y coordinate value).

In addition, the tablet program automatically generates a timestamp t, so the input data generated on the tablet also includes a timestamp.

Step 102: Determine whether the input data is written data generated by a writing operation. If the input data is written data generated by a writing operation, step 103 is performed. If the input data is not written data generated by the writing operation, step 105 is performed.

In the present embodiment, the step of "determining whether the input data is written data generated by a writing operation" includes:

Determining, according to the pressure value included in the input data, whether the input data is written data generated by a writing operation;

If the input data includes a pressure value that is not zero, determining that the input data is written data generated by a writing operation;

If the input data includes a pressure value of zero, it is determined that the input data is not written data generated by a writing operation.

Step 103: Determine whether the input data is the first written data generated by the continuous writing operation. If the input data is the first written data generated by the continuous writing operation, step 104 is performed. If the input data is non-first written data generated by a continuous writing operation, step 105 is performed.

In the present embodiment, the step of "determining whether the input data is the first written data generated by the continuous writing operation" includes:

Determining, according to the pressure value of the input data acquired last time, whether the currently acquired input data is the first written data generated by the continuous writing operation;

If the pressure value of the input data acquired last time is zero, it is determined that the currently acquired input data is the first written data generated by the continuous writing operation;

If the pressure value of the input data acquired last time is not zero, it is judged that the currently acquired input data is the non-first written data generated by the continuous writing operation.

It can be understood that if the pressure value of the input data acquired last time is zero, it can be determined that the input data acquired last time corresponds to a pen-holding operation. At this time, if the currently-acquired input data is a writing operation caused by a writing operation, The data can then determine that the currently acquired input data is the first written data generated by the continuous writing operation.

If the pressure value of the input data acquired last time is not zero, it can be determined that the input data acquired last time corresponds to a pen writing operation. At this time, if the currently input data is the writing data generated by the writing operation, Judge the current acquisition The input data is non-first written data generated by a continuous writing operation.

Step 104: Generate the data packet according to the first data format.

As shown in FIG. 3, the byte length of the data packet of the first data format is a first preset value, and includes four data segments, where the four data segments are respectively used to store X coordinate values, Y. Coordinate value, pressure value, time stamp.

Step 105: Generate the data packet according to the second data format.

As shown in FIG. 4, the byte length of the data packet of the second data format is a second preset value, and includes three data segments, where the three data segments are respectively used to store X coordinate values, Y. Coordinate value, pressure value.

In the present embodiment, the data segments storing the X coordinate value, the Y coordinate value, and the pressure value each have a data length of 2 Bytes, and the data segment storing the time stamp has a data length of 4 Bytes.

In the present embodiment, the pressure value ranges from 0 to 2048. Since the data segment storing the pressure value has a data length of 2 Bytes, and the value ranges from 0 to 65535, the highest bit of the data segment storing the pressure value in the prior art data packet as shown in FIG. 1 is always 0. .

The data packet of the prior art is also separately provided with a data segment of 1 Byte for storing the flag data, wherein the flag bit records the lower pen flag and the pen pen flag, and the pen and the pen are represented by 1 and 0 respectively. That is to say, the prior art data packet has a byte length of 11 Bytes.

In the present embodiment, the highest data bit of the data segment storing the pressure value is also used to store the flag bit data, and the remaining data bits are used to store pressure value data.

For example, when the lower pen generates pressure, the prior art records "01" in the data segment in which the flag bit is stored, and records "01e5" in the data segment in which the pressure value is stored, and the present embodiment removes the data segment in which the flag bit is stored. And "11e5" is recorded in the data segment in which the pressure value is stored. When the pen is raised, no pressure is generated. In the prior art, "00" is recorded in the data segment in which the flag is stored, and "0000" is recorded in the data segment in which the pressure value is stored, and the embodiment stores the data in the pressure value. "0000" is recorded in the segment. In the present embodiment, by storing the flag bit data by using the highest data bit of the data segment storing the pressure value, the storage space of the flag bit of 1 Byte can be reduced, so that the storage space of the data packet can be optimized.

In this embodiment, the time stamp generated by the tablet is a relative time stamp, and the data packet corresponding to the starting point of the writing operation (ie, the first writing point after the pen down) contains the data segment storing the time stamp. The byte length of the data packet corresponding to the starting point is: 2 Bytes (X coordinate value) + 2 Bytes (Y coordinate value) + 2 Bytes (pressure value) + 4 Bytes (time stamp) = 10 Bytes, that is, the first preset value The value is 10 Bytes, and the data packet corresponding to the pen point reduces the storage space of the 1 Byte flag bit compared to the data packet generated by the prior art.

In this embodiment, since the input data on the tablet is generated according to a preset time interval, the time stamp of the data packet corresponding to the non-pick point and the pen up operation can be calculated by accumulating the time stamp of the pen point and the time interval. Therefore, the data packet corresponding to the non-pick point and the pen up operation may not include the data segment storing the time stamp. Non-starting point and number corresponding to the pen up operation According to the byte length of the packet: 2Bytes (X coordinate value) + 2Bytes (Y coordinate value) + 2Bytes (pressure value) = 6Bytes, that is, the value of the second preset value is 6Bytes, non-starting point and lifting The data packet corresponding to the pen operation reduces the storage space of the 5 Byte flag bit compared to the data packet generated by the prior art.

It can be understood that the data packets corresponding to the non-pick point and the pen up operation can also be collectively referred to as non-priming data packets.

Step 106: Send the generated data packet to the receiving end system.

After the step 106, the flow returns to step 101 to continue to acquire input data generated on the tablet at preset time intervals.

It can be understood that, among the input data generated on the tablet, the data packets of the input data corresponding to the non-pick point and the pen-up operation are usually far more than the data packets of the input data corresponding to the pen point, and thus the input data of the present application is adopted. The processing method can reduce the data length of most data packets of the tablet input data from the original 11 Bytes to 6 Bytes, so that the storage capacity and the transmitted data amount are reduced by 45%, and the data length of the data packet of the pen point is also from the original The reduction of 11 Bytes to 10 Bytes reduced the amount of storage capacity and data transferred by at least 9%.

The input data processing method of the tablet of the present application can reduce the number of data segments of the data packet by reorganizing the data format of the data packet without changing the data source, thereby achieving the purpose of reducing the storage capacity and the transmission amount of the data, thereby The storage space occupied by the stored data can be significantly reduced, and the data transmission speed can be improved, so as to improve the response speed of the receiving end system to the writing operation, such as increasing the real-time display speed of the writing track or improving the response speed of the function triggered by the writing operation. To give users a better experience.

Please refer to FIG. 5 , which is a flowchart of a method for processing input data of a tablet according to a second embodiment of the present application. The input data processing method is applied to an electronic device having the tablet. More specifically, the input data processing method is applied to a receiving end system of the electronic device. It should be noted that the input data processing method of the embodiment of the present application is not limited to the steps and the sequence in the flowchart shown in FIG. 5. The steps in the illustrated flow diagrams can be added, removed, or changed in order, depending on the requirements.

As shown in FIG. 5, the input data processing method includes the following steps:

Step 201: Receive a data packet and determine a byte length of the data packet. If the byte length of the data packet is equal to the first preset value, step 202 is performed. If the byte length of the data packet is equal to the second preset value, step 203 is performed.

In this embodiment, the value of the first preset value is 10 Bytes, and the value of the second preset value is 6 Bytes.

Step 202: Determine that the data of the data packet is the first written data generated by the continuous writing operation, and parse the data packet according to the first data format to obtain the tablet data to be processed.

The data packet of the first data format includes four data segments, and the four data segments are respectively used for storing an X coordinate value, a Y coordinate value, a pressure value, and a time stamp.

In this embodiment, the input data processing method includes:

The parsed timestamp is determined as the starting timestamp of the continuous handwriting operation.

Step 203: Parse the data of the data packet according to the second data format to obtain the tablet data to be processed.

The data packet of the second data format includes three data segments, and the three data segments are respectively used for storing an X coordinate value, a Y coordinate value, and a pressure value.

Step 204: Calculate a timestamp of the currently received data packet according to the last parsed timestamp and the number of data packets received after the data packet containing the timestamp.

In this embodiment, the step of “calculating the timestamp of the currently received data packet based on the last timestamp and the number of data packets received after the data packet containing the timestamp” includes :

Obtaining the timestamp that was last parsed and the preset time interval for generating two adjacent input data;

Determining the number of data packets received after the data packet containing the timestamp;

Calculating a product of the number of the data packets and the preset time interval;

Calculating a sum of the timestamp and the product;

The sum of the timestamp and the product is taken as the timestamp of the currently received data packet.

It can be understood that the timestamp that was last parsed refers to the start timestamp of the latest continuous writing operation.

In this embodiment, the time stamp generated by the tablet is a relative time stamp. When the pen is written, the tablet program automatically generates the time stamp t, and the data packet corresponding to the starting point of the writing operation generated by the tablet system includes the storage time stamp. The data segment, and the byte length of the packet corresponding to the pen point is: 2Bytes (X coordinate value) + 2Bytes (Y coordinate value) + 2Bytes (pressure value) + 4Bytes (time stamp) = 10Bytes. When the receiving end system receives a data packet with a byte length of 10 Bytes, it can parse the writing time stamp of the writing operation, which can also be called a starting time stamp.

The data packet generated after the starting point and before the next writing operation does not include the data segment storing the time stamp, and the byte length of the corresponding data packet is: 2 Bytes (X coordinate value) + 2 Bytes (Y coordinate value) + 2 Bytes (pressure value) = 6 Bytes. When the receiving end system receives a packet with a byte length of 6 Bytes, it can determine that the data packet does not contain a timestamp, and can automatically generate a timestamp for the data packet. It can be understood that the generated data packets after the starting point and before the next writing operation can also be collectively referred to as non-priming data packets.

Assuming that the start timestamp is t0, the timestamp of the non-primed data packet is t, and the preset time interval for generating two adjacent input data is Δt, and the start data time stamp is included in the data packet (ie, the start time stamp is included) The number of data packets received after the data packet is N, and the time stamp of the non-priming data packet is t=t0+Δt*N.

Step 205: Add the calculated time stamp to the to-be-written tablet data.

Step 206: Analyze and process the tablet data to be processed.

In this embodiment, the input data processing method further includes:

Parsing data of a highest data bit of the data segment storing the pressure value into flag data, wherein the flag bit includes a pen down flag and a pen pen flag;

The data of the remaining data bits of the data segment storing the pressure value is parsed into pressure value data.

In this embodiment, the input data processing method further includes:

Determining the type of data of the data packet based on the byte length of the data packet and the flag bit data and the pressure value data obtained by parsing the data packet.

Wherein, if the byte length of the data packet is equal to the second preset value, the flag bit data is a pen down mark, and the pressure value is not zero, determining that the data of the data packet is generated by a continuous writing operation Not the first to write data.

If the byte length of the data packet is equal to the second preset value, the flag bit data is a pen up flag, and the pressure value is zero, it is determined that the data of the data packet is data of a tablet cursor position.

In this embodiment, the analysis processing of the tablet data to be processed includes, but is not limited to, displaying a writing track in real time according to the tablet data to be processed, or triggering a corresponding function application according to the tablet data to be processed. .

After the step 206, the flow returns to step 201 to continue receiving the data packet and determining the byte length of the data packet.

The input data processing method of the tablet of the present application can parse the received data packet by using different data formats according to the byte length of the data packet when receiving the data packet, and automatically provide the data that does not include the time stamp. The packet generates a corresponding timestamp, which can help the tablet system to reduce the byte length of the data packet when generating the data packet, so as to significantly reduce the storage space occupied by the stored data and increase the data transmission speed.
