Specifically, if the first end of the pen body 110 is the lower end of the smart pen, the pen body 110 The second end is the upper end of the smart pen; if the first end of the pen body 110 is the upper end of the smart pen, the second end of the pen body 110 is the lower end of the smart pen.

Wherein, the trackball 130 can be pressed and rotated by a user.

Specifically, when the trackball 130 is rotated, the trackball 130 drives the roller 140 to rotate, and the photoelectric pulse signal generated by the sensor 150 mounted at the end of the roller 140 reflects the rotation direction and the rotation range of the trackball 130, and then passes through the program. Processing and conversion to control the movement of the cursor on the screen. It should be noted that FIG. 1 is only a schematic diagram showing the structure of the smart pen. Especially for the roller column 140 and the track ball 130, FIG. 1 does not reflect the actual cooperation relationship.

Wherein, the sensor 150 may be a grating signal sensor, and the grating signal sensor is a sensor that measures displacement by using a grating-stacking stripe principle.

Optionally, a pen is placed inside the pen body 110, and the dragging operation of the writing content on the smart tablet can be implemented by combining the pressing switch and the scrolling of the trackball. For example, after pressing the switch on the smart pen, the writing content specified by the cursor is selected. The movement of the selected writing content and the dragging operation are realized by rotating the trackball.

The writing tip 120 is used for moving on the screen of the smart tablet, and the writing is realized by detecting the motion by the touch panel of the smart tablet.

At the same time, it provides users with a new operating experience.

Embodiment 2

2 is a flowchart of a method for controlling a smart pen according to a second embodiment of the present invention. The present embodiment can be applied to the control of a smart pen. The method can be executed by the control device of the smart pen in the embodiment of the present invention. The device may be implemented in software and/or hardware. As shown in FIG. 2, the method specifically includes the following steps:

S210: Acquire a pulse signal generated when the trackball rotates by using a sensor built in the smart pen.

The sensor built in the smart pen may be a grating signal sensor, and the sensor is mounted on the end of the roller column, and can generate a pulse signal when the roller is rotated by the track ball.

Specifically, the pulse signal generated by the rotation of the trackball is acquired by the sensor built in the smart pen.

S220, determining a rotation direction and a rotation amplitude of the trackball according to the pulse signal.

Wherein, the rotation direction of the trackball may be a horizontal rotation or a vertical rotation. For example, if the user rotates the trackball to the left, the direction of rotation of the trackball is horizontal to the left; if the user rotates the trackball to the right, the direction of rotation of the trackball is horizontal to the right.

Wherein, the rotation amplitude of the trackball is the distance that the trackball rotates in the horizontal direction or the vertical direction. For example, if the user rotates the trackball to the left, the distance that the trackball rotates to the left is the rotation range of the trackball; The user rotates the trackball to the right, and the distance the trackball rotates to the right is the range of rotation of the trackball.

Specifically, since the track ball drives the roller column to rotate, the sensor disposed at the end of the roller column collects a pulse signal, and determines the rotation direction and the rotation range of the trackball according to the pulse signal collected by the sensor.

S230, controlling a movement track of the cursor on the screen of the smart tablet according to the rotation direction and the rotation amplitude.

Wherein, the cursor is a small vertical line, a short small horizontal line or an arrow presented on a display area of the smart flat screen, and the Windows system is a position that changes a computer command into coordinates on the display screen, for example: various menus, Labels, buttons, etc., when the cursor is at this position, is aligned with this computer command, when you press the corresponding switch, it is to command the computer to execute the instruction you align with the cursor.

Specifically, the trackball rotates, the trackball drives the roller column to rotate, and the photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller column reflects the rotation direction and the rotation amplitude of the trackball, and controls the screen through processing and conversion of the computer program. The movement of the cursor.

Optionally, after determining the rotation direction and the rotation range of the trackball according to the pulse signal, the method further includes:

The triggering operation may be implemented by pressing a switch on the smart pen, or by triggering a touch area on the smart pen, which is not limited in this embodiment.

Specifically, when the triggering operation is acquired, the writing content on the smart tablet corresponding to the cursor is selected, and then the moving track of the writing content on the smart tablet screen is controlled according to the rotation direction and the rotation amplitude of the trackball. For example, the user may select a picture corresponding to the current cursor by pressing a switch, and if the user rotates the track ball to the left, the selected image is moved to the left.

The technical solution of the embodiment obtains a pulse signal generated when the trackball rotates by using a sensor built in the smart pen; determines a rotation direction and a rotation range of the trackball according to the pulse signal; and controls a cursor on the smart tablet screen according to the rotation direction and the rotation amplitude. The trajectory can expand the way the smart pen interacts, and can provide users with a new operating experience while improving the comfort of the user during remote control.

Embodiment 3

3 is a flowchart of a method for controlling a smart pen according to a third embodiment of the present invention. The present embodiment is optimized based on the foregoing embodiment. In this embodiment, the rotation direction of the trackball is determined according to the pulse signal. After the amplitude of the rotation, the method further includes: collecting the current orientation of the smart pen by using a sensor built in the smart pen; if the current orientation of the smart pen is the first preset direction, setting the writing mode corresponding to the smart pen to erase A mode in which an original writing trajectory coincident with a displacement of the trackball in a vertical and horizontal direction is erased.

As shown in FIG. 3, the method in this embodiment specifically includes the following steps:

S310: Acquire a pulse signal generated when the trackball rotates by using a sensor built in the smart pen.

S320, determining a rotation direction and a rotation range of the trackball according to the pulse signal.

S330: Collect the current orientation of the smart pen through the built-in sensor of the smart pen.

The sensor may be an acceleration sensor or a gyroscope.

Specifically, if the sensor is an acceleration sensor, the current orientation of the smart pen can be determined according to the measured acceleration value; if the sensor is a gyroscope, the current orientation of the smart pen can be directly measured.

S340, if the current orientation of the smart pen is the first preset direction, setting the writing mode corresponding to the smart pen to the erasing mode, and erasing the original of the displacement of the trackball in the vertical and horizontal directions in the erasing mode. There is a writing track.

The first preset direction may be a direction set by the user, or may be a direction that is convenient for the user to use. For example, the user is accustomed to press the smart pen to turn the tip of the pen upward toward the trackball, and press the trackball. Scrolling on the table allows for erasing in the smart tablet or annotation software, so the first preset direction can be set to be vertically downward.

Specifically, in the erasing mode, the displacement of the trackball of the smart pen in the vertical and horizontal directions is matched with the original writing track, and if the track of the trackball of the smart pen is in the erase mode and the original writing track is If they coincide, the original writing track will be erased. For example, in a whiteboard or annotation software, we can erase by pressing the pen on the table and scrolling through the whiteboard or annotation software. This kind of interaction is very close to the erasure in life, which can greatly enhance the user experience.

Optionally, it also includes:

The manner in which the pressure generated by the trackball is generated may be generated by the user pressing the finger, or may be generated by the user pressing the trackball on the table, which is not limited in this embodiment.

Specifically, the pressure applied by the user on the trackball is collected by a pressure sensor built in the smart pen.

If the pressure value is greater than the first pressure threshold, and the duration of the pressure value is greater than the first preset time, performing the first preset operation;

The first threshold may be set by a user, or may be data obtained according to experience.

The first preset time may be a shorter period of time, or may be a longer period of time. If the first preset time is a shorter period of time, the user's pressing operation may be regarded as a click. Event; if the first preset time is a long period of time, the user's pressing operation can be regarded as a long press event.

The first preset operation may be a selected operation, or may be an application that opens a certain setting, or may be an open menu, or may be an edit mode, etc., for example, if the first preset When the time is a short period of time, the user's pressing operation is regarded as a click event, and the operation of simulating the left mouse button is performed. If the first preset time is a long period of time, the user's pressing operation is regarded as a long press event, and the right mouse button menu operation is performed.

Specifically, when the user only presses the trackball within the preset time, does not rotate the trackball, and the pressure value of the pressing is greater than the first pressure threshold, the first preset operation is performed.

The second preset time is set by the user, and may also be an experience acquisition, and the second preset time is a shorter time period.

The second preset operation is different from the first preset operation. If the first preset operation is to simulate a left button operation of the mouse, the second preset operation may be an operation of simulating a right mouse button or a selected operation. It can also be an application that opens a certain setting, or it can be an open menu, or it can be some sort of editing mode.

Specifically, the user will press the trackball twice in a row without rotating the trackball, and the pressure value of the pressing is greater than the first pressure threshold, and then performing the second preset operation.

Specifically, one press in a period of time can be converted into a one-click event. Reflected on the interaction, click can be used to simulate the left button operation of the mouse, or it can be customized to other events, such as opening a specific application. Continuous compression over a period of time can be converted into a double click event. Reflected on the interaction, double-click can be used to simulate the double-click operation of the mouse, and can also be used to simulate the right-click operation of the mouse, or customize to other interactive events. A press that exceeds a certain time range can be converted into a long press event. Reflected in the interaction, long press can be used to open the right-click menu operation, or to perform some sort of editing mode and so on.

In a specific example, a trackball is added to the end of the smart pen, which can be rotated, pressed, and most intuitively rotated by the trackball to position the cursor. The system knows the position of the current cursor. We only need to convert the rotation amplitude of the trackball in the up, down, left and right directions into the change value of the X and Y axis coordinates of the mouse on the screen. This way, the user can easily and comfortably operate the smart pen, move the cursor to the area he wants to operate, and move the cursor to the target area easily after moving. In the mode of document, web browsing, etc., we can also scroll through the page easily by scrolling, which is much more precise than the original smart pen. By combining the buttons, it is easy to realize some operations that need to be moved and dragged by the trackball rotation. In the technical solution of the embodiment, the pulse signal generated when the trackball is rotated is obtained by the built-in sensor of the smart pen, and the rotation direction and the rotation range of the trackball are determined according to the pulse signal, and the current orientation of the smart pen is collected by the built-in sensor of the smart pen. The current orientation of the smart pen is a first preset direction, and the writing mode corresponding to the smart pen is set to an erasing mode, in which the erasing coincides with the displacement of the trackball in the vertical and horizontal directions. The original writing track can expand the interaction mode of the smart pen, and can provide users with a new operating experience while improving the comfort of the user during remote control.
