In some embodiments, the terminal 30 is also used to receive the writing operation of the stylus 10 to obtain touch writing instructions.

Specifically, the terminal 30 may have a touch function, may receive the writing operation of the stylus 10 to obtain the touch writing instruction, and may communicate with the stylus 10 to receive the touch operation instruction of the stylus 10, and then the terminal 30 may Control operation instructions and touch writing instructions to perform corresponding operations, without receiving writing operations through the tablet 20, the stylus 10 can be directly controlled by the terminal 30 to adjust the depth and thickness of the stroke, and the control terminal 30 can perform page turning operations, zoom operations, etc. operating.

Please refer to FIG. 2 again. In some embodiments, the terminal 30 includes a mobile phone, a tablet computer, a notebook computer, a smart wearable device, and so on.

Please refer to FIGS. 2 and 3. In some embodiments, the touch operation instruction includes a single-finger slide operation instruction, and step 012 includes the following steps:

0121: Obtain the trajectory data when the flexible sensor 16 receives the single finger sliding operation; and

0122: Generate a single finger slide operation instruction based on the trajectory data.

In some embodiments, the stylus 10 is also used to obtain trajectory data when the flexible sensor 16 receives a single-finger sliding operation, and generate a single-finger sliding operation instruction according to the trajectory data.

That is to say, step 0121 and step 0122 can be implemented by the stylus pen 10.

Specifically, referring to FIG. 4, when the user performs a touch operation on the flexible sensor 16, the flexible sensor 16 can obtain the trajectory data of the touch operation, and according to the trajectory data, it can be determined whether the user performs a single-finger sliding operation, so that The data generates a single finger slide operation instruction. For example, the single-finger sliding operation is a single finger sliding, and the track data collected in the flexible sensor 16 is a track and the length of the track is greater than a predetermined sliding distance, it can be determined that the received touch operation is a single-finger sliding operation, handwriting The pen 10 can accurately distinguish between click and slide by judging the relationship between the length of the track and the predetermined sliding distance, and prevent misjudgment when the user accidentally touches.

Please refer to FIG. 2, FIG. 4 and FIG. 5. In some implementations, the touch writing instructions include the wake-up instruction generated when the stylus 10 is dropped on the tablet 20 and the one generated when the stylus 10 is written on the tablet 20 For writing instructions, the terminal 30 includes a display 32 and a processor 34, and the display content of the display 32 corresponds to the writing instructions; Step 016 includes the following steps:

0161: wake up the stylus 10 according to the wake-up instruction;

0162: Set the stroke thickness of the displayed content according to the single finger slide operation instruction; and

0163: Display the display content on the terminal 30 according to the stroke thickness.

In some embodiments, the processor 34 is used to wake up the stylus 10 according to the wake-up instruction and set the stroke thickness of the displayed content according to the single-finger slide operation instruction; the display 32 is used to display the displayed content on the terminal 30 according to the stroke thickness.

That is to say, step 0161 and step 0162 can be implemented by the processor 34. Step 0163 may be implemented by the display 32.

Specifically, the tablet 20, the stylus 10, and the terminal 30 communicate with each other, and the user sets the attributes of the content to be written through the touch operation, that is, the user sets the stroke thickness and flexibility of the displayed content through the single finger sliding operation After receiving the single-finger sliding operation, the sensor 16 generates a single-finger sliding operation instruction. When the stylus 10 is dropped on the tablet 20, that is, when the user is about to start a touch writing operation, the tablet 20 perceives the touch writing operation and notifies the terminal 30 , The terminal 30 generates a wake-up instruction according to the notification, and the terminal 30 sends the wake-up instruction to the stylus 10 to request the single-finger sliding operation instruction generated by the stylus 10. After receiving the wake-up instruction, the stylus 10 sends the single-finger sliding operation instruction to the handwriting The tablet 20, after the user performs a touch writing operation on the tablet 20, the tablet 20 generates a writing instruction and then sends the writing instruction and the single-finger sliding operation instruction to the processor 34 of the terminal 30. The slide operation instruction sets the stroke thickness of the displayed content. The display 32 displays the display content corresponding to the writing instruction according to the set stroke thickness. When the user is dissatisfied with the stroke thickness of the currently displayed content, the user can perform a single finger on the flexible sensor 16 again Slide to adjust the thickness of the stroke.

Please refer to FIGS. 2, 4 and 6. In some embodiments, the flexible sensor 16 includes opposite first ends 162 and second ends 164, and the trajectory data includes the sliding direction and sliding distance of the single-finger sliding operation, step 0162 It includes the following steps:

01622: When the sliding direction slides from the first end 162 to the second end 164, the stroke is adjusted thicker according to the sliding distance; and

01624: When the sliding direction slides from the second end 164 to the first end 162, the stroke is adjusted to be thinner according to the sliding distance.

In some embodiments, the processor 34 is further configured to adjust the stroke to thicken according to the sliding distance when the sliding direction is from the first end 162 to the second end 164, and to slide from the second end 164 to the second direction in the sliding direction At one end of 162, the stroke is adjusted to be thinner according to the sliding distance.

That is to say, step 01622 and step 01624 can be implemented by the processor 34.

Specifically, referring to FIG. 4 again, the processor 34 can calculate the starting point and the ending point of the trajectory according to the trajectory data, where the starting point is the position where the hand touches the flexible sensor 16 during the single-finger sliding operation, and the ending point is the single-finger sliding At the end of the operation, when the hand leaves or stops sliding at the position of the flexible sensor 16, the direction from the starting point to the ending point is the sliding direction of the single-finger sliding operation. If the starting point is close to the first end 162, the ending point is close to the second end 164, Then the sliding direction is from the first end 162 to the second end 164. At this time, the thickness of the stroke is adjusted according to the distance between the start point and the end point (that is, the sliding distance), and the sliding direction can be set when the first end 162 is toward the second end 164 , The farther the sliding distance, the thicker the stroke. For example, the first end 162 is the top end of the flexible sensor 16 (that is, the end of the flexible sensor 16 away from the pen head 14), and the second end 164 is the bottom end of the flexible sensor 16 (that is, the flexible sensor 16 Near the end of the pen tip 14), the user only needs to slide a single finger from the top to the bottom of the flexible sensor 16 when holding the stylus 10, and the stroke becomes thicker as the sliding distance becomes larger; otherwise, the user holds the handwriting The pen 10 only needs one finger to slide from the bottom to the top of the flexible sensor 16, and as the sliding distance becomes larger, the stroke becomes thinner. For another example, the first end 162 is the bottom end of the flexible sensor 16 (that is, the end of the flexible sensor 16 close to the pen tip 14), and the second end 164 is the top end of the flexible sensor 16 (that is, the end of the flexible sensor 16 far from the pen head 14), adjustment method It is similar to the above method and will not be repeated here. In this way, the user can adjust the stroke thickness conveniently with a single finger slide operation.

Please refer to FIGS. 2, 7 and 8. In some embodiments, the touch operation instruction includes a two-finger slide operation instruction, and step 012 further includes the following steps:

0123: Obtain the trajectory data when the flexible sensor 16 receives the two-finger sliding operation; and

0124: Generate a two-finger slide operation instruction based on the trajectory data.

In some embodiments, the stylus 10 is also used to obtain trajectory data when the flexible sensor 16 receives a two-finger sliding operation, and generate a two-finger sliding operation instruction according to the trajectory data.

That is to say, step 0123 and step 0124 can be implemented by the stylus pen 10.

Specifically, when the user performs a touch operation on the flexible sensor 16, the flexible sensor 16 can obtain the track data of the touch operation, and the stylus 10 can determine whether the user performs a two-finger sliding operation according to the track data, thereby generating from the track data Two-finger swipe instruction. For example, the two-finger sliding operation is two fingers sliding, the track data collected in the flexible sensor 16 is two tracks, and the length of the track is greater than a predetermined sliding distance to determine that the received touch operation is a two-finger sliding operation. The stylus 10 can accurately distinguish between two-finger clicks and two-finger slides by determining whether the two tracks are longer than the predetermined sliding distance.

Please refer to FIG. 2, FIG. 8 and FIG. 9. In some embodiments, the touch writing instruction includes a wake-up instruction generated when the stylus 10 is dropped on the handwriting board 20; Step 016 includes the following steps:

0164: wake up the stylus 10 according to the wake-up instruction; and

0165: Control the terminal 30 to perform the page turning operation according to the two-finger slide operation instruction.

In some embodiments, the processor 34 is further configured to wake up the stylus 10 according to the wake-up instruction and control the terminal 30 to perform the page turning operation according to the two-finger sliding operation instruction.

That is to say, step 0164 and step 0165 can be implemented by the processor 34.

Specifically, when the user only needs to perform a page turning operation on the terminal 30 to view the previously written content, the user first writes the pen on the tablet 20, the tablet 20 perceives the pen-writing operation and notifies the terminal 30, and the terminal 30 generates a wake-up according to the notification Command and send it to the stylus 10 to request the touch operation instruction generated by the stylus 10. After receiving the wake-up instruction, the stylus 10 sends a two-finger sliding operation instruction to the handwriting board 20, and the handwriting board 20 sends the two-finger sliding operation instruction To the processor 34, the processor 34 controls the terminal 30 to perform a page turning operation according to the two-finger sliding operation instruction.

Please refer to FIGS. 2, 8, 10 and 11. In some embodiments, the flexible sensor 16 includes opposite first ends 162 and second ends 164, and the trajectory data includes the sliding direction and sliding distance of the two-finger sliding operation , Step 0165 includes the following steps:

01652: When the two-finger sliding operation slides from the first end 162 to the second end 164 and the sliding distance is greater than or equal to the predetermined page turning distance, the control terminal 30 performs page turning downward; and

01654: When the two-finger sliding operation slides from the second end 164 to the first end 162 and the sliding distance is greater than or equal to the predetermined page turning distance, the control terminal 30 executes page turning upward.

In some embodiments, the processor 34 is further configured to obtain the sliding direction and sliding distance of the two-finger sliding operation according to the trajectory data, and slide from the first end 162 to the second end 164 during the two-finger sliding operation and the sliding distance is greater than or equal to When the page turning distance is predetermined, the control terminal 30 performs page turning downward, and when the two-finger sliding operation slides from the second end 164 to the first end 162 and the sliding distance is greater than or equal to the predetermined page turning distance, the control terminal 30 performs page turning upward page.

That is to say, step 01652 and step 01654 can be implemented by the processor 34.

Specifically, the processor 34 can calculate the start point and the end point of the trajectory according to the trajectory data. Since the two-finger slide is the simultaneous sliding of two fingers, the length of the trajectory traced by the two fingers is basically the same. When the length is basically the same, the starting point is the position where any one finger touches the flexible sensor 16 during the two-finger sliding operation, and the ending point is the position of the flexible sensor 16 when the hand leaves or stops sliding after the single-finger sliding operation ends. The direction of the end point is the sliding direction of the two-finger sliding operation. If the starting point is close to the first end 162 and the ending point is close to the second end 164, the sliding direction is from the first end 162 to the second end 164; then, the processor 34 Determine whether the sliding distance is greater than or equal to the predetermined page turning distance, perform a page turning operation when the sliding distance is greater than or equal to the predetermined page turning distance, to prevent two fingers from contacting only the flexible sensor 16 without sliding, or if one finger contacts the flexible sensor 16 The two touch operations of sliding and the other finger sliding on the flexible sensor 16 are erroneously judged as a two-finger sliding operation, which can accurately determine whether the user wants to perform a page turning operation. For example, as shown in FIG. 8, the user's two fingers slide from the top end (first end 162) to the bottom end (second end 164) of the flexible sensor 16, and then slide a certain distance (greater than or equal to the predetermined page turning distance) Control the display 32 to perform page down; on the contrary, as shown in FIG. 11, the user's two fingers slide from the bottom end (second end 164) of the flexible sensor 16 to the bottom end (first end 162), and then slide a certain distance ( Greater than or equal to the predetermined page turning distance) to control the display 32 to perform page turning upwards. In this way, the user can easily perform page turning operations.

Please refer to FIG. 2, FIG. 12 and FIG. 13. In some embodiments, the touch operation instruction includes a two-finger press operation instruction, and step 012 further includes the following steps:

0125: Obtain the trajectory data and pressure data when the flexible sensor 16 receives the two-finger press operation; and

0126: Generate a two-finger press operation instruction based on the trajectory data and pressure data.

In some embodiments, the stylus pen 10 is also used to obtain trajectory data and pressure data when the flexible sensor 16 receives a two-finger pressing operation, and generate a two-finger pressing operation instruction according to the trajectory data and the pressure data.

That is to say, step 0125 and step 0126 can be implemented by the stylus pen 10.

Specifically, when the user performs a touch operation on the flexible sensor 16, the flexible sensor 16 can obtain the track data and pressure data of the touch operation, and can determine whether the user performs the two-finger operation according to the track data. For example, the two-finger operation is Two fingers. When the track data collected in the flexible sensor 16 is two tracks, it can be determined that the received touch operation is a two-finger operation. According to the pressure data, it is determined whether the user has pressed. When the pressure value is greater than the predetermined pressure value, it is judged that the user has performed the two-finger pressing operation, thereby accurately distinguishing the two-finger sliding operation and the two-finger pressing operation.

Please refer to FIGS. 2, 13 and 14. In some embodiments, the terminal 30 includes a display 32 and a processor 34. The touch writing instruction includes the wake-up instruction generated when the stylus 10 is dropped on the tablet 20 and the writing instruction generated when the stylus 10 is written on the tablet 20. The display content of the display 32 corresponds to the writing instruction; Step 016 includes the following steps :

0166: wake up the stylus 10 according to the wake-up instruction;

0167: Set the transparency of the stroke of the displayed content according to the two-finger press operation instruction; and

0168: Display the display content on the terminal 30 according to the transparency of the stroke.

In some embodiments, the terminal 30 includes a display 32 and a processor 34. The processor 34 is also used to wake up the stylus 10 according to the wake-up instruction and to set the transparency of the stroke of the displayed content according to the two-finger press operation instruction; the display 32 is also used to display the displayed content on the terminal 30 according to the transparency of the stroke.

That is to say, step 0166 and step 0167 can be implemented by the processor 34. Step 0168 may be implemented by the display 32.

Specifically, when the user wants to adjust the transparency of the written stroke, the user first puts the pen on the tablet 20. The tablet 20 perceives the pen-drop operation and notifies the terminal 30. The terminal 30 accordingly generates a wake-up instruction and sends it to the stylus 10 to Request to obtain the touch operation instruction generated by the stylus 10. After receiving the wake-up instruction, the stylus 10 sends a two-finger press operation instruction to the tablet 20. After the user performs a touch writing operation on the tablet 20, the tablet 20 Generate a writing instruction and then send the writing instruction and the two-finger pressing operation instruction to the processor 34. The processor 34 sets the transparency of the stroke (ie, the depth of the stroke) according to the two-finger pressing operation instruction. The display 32 displays the When the display content corresponding to the writing instruction is dissatisfied with the transparency of the stroke of the currently displayed content, the user can adjust the transparency of the stroke of the displayed content by performing a two-finger press operation on the flexible sensor 16 again.

Please refer to FIG. 2, FIG. 13 and FIG. 15. In some embodiments, the flexible sensor 16 includes opposite first and second ends 162 and 164. Step 0167 includes the following steps:

01672: Set the transparency of the current display content according to the difference between the current pressure data of the two-finger press operation instruction and the initial pressure data or the pressure data of the last acquired two-finger press operation instruction, where the initial pressure data Is zero.

In some embodiments, the processor 34 is further configured to set the current value according to the difference between the pressure data of the current two-finger press operation instruction and the initial pressure data or the pressure data of the last acquired two-finger press operation instruction. The transparency of the display content, where the initial pressure data is zero.

That is to say, step 01672 can be implemented by the processor 34.

Specifically, the initial pressure data is zero, and the calculation of the stroke transparency meets the following formula: OP=K*|f1-f2|, where f1 is the pressure data corresponding to the two-finger press instruction currently received by the processor 34, f2 Is the pressure data or initial pressure data corresponding to the last two-finger pressing instruction received by the processor 34, K is a predetermined coefficient as a constant, that is, the currently received two-finger pressing instruction is the first time the user performs When the two-finger pressing operation command is generated by the two-finger pressing operation, f2 is the initial pressure data 0. In this way, the user realizes the setting of transparency through a two-finger press operation.

Please refer to FIGS. 2, 16 and 17. In some embodiments, the touch operation instruction includes a double-click operation instruction, and step 012 further includes the following steps:

0127: Obtain the trajectory data and/or pressure data when the flexible sensor 16 receives the double-click operation; and

0128: Generate double-click operation instructions based on track data and/or pressure data.

In some embodiments, the stylus pen 10 is also used to obtain trajectory data and/or pressure data when the flexible sensor 16 receives a double-click operation, and generate a double-click operation instruction according to the trajectory data and/or pressure data.

That is to say, step 0127 and step 0128 can be implemented by the stylus pen 10.

Specifically, when the user performs a touch operation on the flexible sensor 16, the flexible sensor 16 can obtain the trajectory data and pressure data of the touch operation. The stylus 10 uses the trajectory data to determine whether the user performs a double-click operation, and the user touches for the first time. The operation is to generate a trajectory, the size of the trajectory is basically the same as the area touched by the finger, rather than a trajectory with a longer length, which means that the user's first touch operation is a click operation. Similarly, the next second touch operation can be judged Whether it is a click operation, after the second touch operation is also a click operation, the stylus pen 10 judges the time interval between the first click operation and the second click operation, if the time interval is less than or equal to the predetermined time interval, it means the user Performed two consecutive click operations, that is, double-click operations. Or, the stylus 10 uses the pressure data to determine whether the user performs a double-click operation. The user generates a pressure data when performing a double-click operation. When the user performs a double-click operation, the flexible sensor 16 generates two pressure data, although the sliding operation also generates pressure data , But the relative click operation takes a long time, so by determining whether the time interval between two consecutive touch operations is less than or equal to the predetermined time interval, the stylus 10 can more accurately distinguish whether the user's two consecutive touch operations are double-click operations or continuous Two slide operations. Alternatively, the stylus 10 uses the trajectory data and pressure data to determine whether the user double-clicks. First, the trajectory data accurately determines whether it is two consecutive click operations, two consecutive sliding operations, or one click and one sliding operation, and then the continuous The pressure data generated by the two touch operations once again determines whether it is a click operation, because sometimes a false touch may occur. At this time, the hand only touches the flexible sensor 16, and if it is judged according to the trajectory, it will also be judged as a click operation. , The pressure received by the flexible sensor 16 is very small, so the pressure value corresponding to the pressure data of the touch operation is compared with the predetermined pressure value. If the pressure value of the touch operation is greater than or equal to the predetermined pressure value, it means that the user is not The touch operation was initiated by mistake. After the stylus 10 judges that the user's two consecutive touch operations are click operations through the track data and pressure data, the stylus 10 determines whether the time interval between the two consecutive click operations is greater than or It is equal to the predetermined time interval. If the time interval between two consecutive click operations is greater than the predetermined time interval, it can be determined that the user has performed a double-click operation. In this way, the stylus 10 uses the trajectory data and pressure data to perform the double-click operation judgment with high accuracy. .

Please refer to FIG. 2, FIG. 17 and FIG. 18. In some embodiments, the touch writing instruction includes a wake-up instruction generated when the stylus 10 is dropped on the tablet 20; Step 016 includes the following steps:

0169: wake up the stylus 10 according to the wake-up instruction; and

0170: Control the terminal 30 to zoom the display content of the display 34 according to the double-click operation instruction.

In some embodiments, the processor 34 is also used to wake up the stylus 10 according to the wake-up instruction and control the display content of the display 34 of the display 32 according to the double-click operation instruction.

That is to say, step 0169 and step 0170 can be implemented by the processor 34.

Specifically, when the user only needs to zoom the display content of the display 32 to zoom in or out to view the display content, the user first draws the pen on the tablet 20. The tablet 20 perceives the pen-down operation and notifies the terminal 30, and the terminal 30 accordingly Notify that a wake-up instruction is generated and send it to the stylus 10 to request the double-click operation instruction generated by the stylus 10. After receiving the wake-up instruction, the stylus 10 sends a double-click operation instruction to the tablet 20, and the tablet 20 sends the double-click operation instruction to the process According to the double-click operation instruction, the processor 34 controls the display 32 to zoom the display content of the display 32.

Please refer to FIG. 2, FIG. 18 and FIG. 19. In some embodiments, the terminal 30 includes multiple preset zoom ratios that are executed sequentially and cyclically. Step 0170 includes the following steps:

01702: Obtain the current zoom ratio of the current display content of the terminal 30; and

01704: Control the terminal 30 according to the double-click operation instruction to zoom the display content at a preset zoom ratio that is next to the current zoom ratio among the multiple preset zoom ratios.

In some embodiments, the processor 34 is further configured to obtain the current zoom ratio of the current display content of the terminal 30, and control the terminal 30 according to the double-click operation instruction to preset the one below the current zoom ratio among the multiple preset zoom ratios The zoom ratio scales the display content.

That is to say, step 01702 and step 01704 can be implemented by the processor 34.

Specifically, taking the preset zoom ratio including the first preset zoom ratio and the second preset zoom ratio as an example, when the user double-clicks to zoom the display content of the display 32, the processor 34 first obtains the zoom ratio of the current page When the zoom ratio of the current page is the first preset zoom ratio, the processor 34 controls the display 32 to zoom the current display content according to the next preset zoom ratio (ie, the second preset zoom ratio) of the first preset zoom ratio; When the zoom ratio of the current page is the second preset zoom ratio, since multiple preset zoom ratios are executed sequentially and sequentially, the next preset zoom ratio of the second preset zoom ratio is the first preset zoom ratio The processor 34 controls the display 32 to scale the currently displayed content according to the first preset scaling ratio. For example, assuming that the first preset zoom ratio is 1, and the second preset zoom ratio is 0.5, when the current zoom ratio is the first preset zoom ratio 1, the coordinates of the displayed content are (X, Y), when the processor 34 Receiving the double-click operation instruction, the processor 34 will control the display 32 to reduce the current display content according to the second preset zoom ratio of 0.5, then the coordinates of the display content after the reduction becomes (0.5X, 0.5Y), thereby achieving the reduction of the display content . When the current zoom ratio is the second preset zoom ratio of 0.5, the coordinates of the displayed content are (0.5X, 0.5Y). When the processor 34 receives the double-click operation instruction, the processor 34 will control the display 32 to press the first preset Zoom ratio 1 zooms the current display content, then the coordinates of the display content after zooming becomes (X, Y), thereby realizing the enlargement of the display content.

In other embodiments, the zoom ratio may include more different zoom ratios. For example, the zoom ratio includes a first preset zoom ratio of 1, a second preset zoom ratio of 0.5, and a third preset zoom ratio of 2. A preset zoom ratio is 2, a second preset zoom ratio is 1 and a third preset zoom ratio is 0.5, then when the current zoom ratio is the second preset zoom ratio 1, when the processor 34 receives the Double-click operation instruction, the processor 34 will control the display 32 to reduce the current display content according to the third preset zoom ratio 0.5, when the processor 34 receives the double-click operation instruction for the second time, the processor 34 will control the display 32 according to the first Set zoom ratio 2 to enlarge the current display content.
