[0050] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as generally understood by those skilled in the art in the art to which the present invention belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as herein.

[0051] Embodiment 1

[0052] like Figure 1 and Figure 2 As shown, a smart pen according to an embodiment of the present invention is provided, comprising a pen head 1 and a pen body 2 connected together:

[0053] The pen body 2 includes an MCU module A201, a camera module A202, a G-sensor module A203, a communication module A204, a prompt module A206 and a power module A205, wherein the camera module A202, the G-sensor module A203, the communication module A204 and the prompt module A206 are all connected to the power module A205 and the MCU module A201, and the MCU module A201 is connected to the power module A205;

[0054] MCU module A201 is used for data collection, data processing and controlling the data output of other modules;

[0055] The MCU includes a data processing unit for sorting and classifying the data transmitted by the camera module A202 and the G-sensor module A203, such as Figure 3 As shown, the specific steps for subject classification are as follows:

[0056] S301 performs coding analysis on the coded information;

[0057] S302: input the content of the coding analysis into a preset text library to search all disciplines to obtain search results, and the search results are used to mark which discipline the content of the coding analysis belongs to;

[0058] S303 classifies and integrates disciplines according to the search results to obtain classification and integration results, where integration refers to logical integration.

[0059] The MCU module A201 controls the communication module A204 to output classification and integration results to the mobile device and server.

[0060] The camera module A202 includes a camera, which is installed near the pen tip and adjusted at an angle to obtain writing track information. The track information is the trace of the pen tip on the paper with a preset code. For example, the code on the paper is small code points. When writing, the pen tip connects the small code points on the paper to form a track. The track is the track information that the camera module A202 needs to obtain and analyze.

[0061] The camera module A202 also includes an anti-shake component to cooperate with the camera to obtain clear trajectory information;

[0062] The camera module A202 also includes an information processing unit to convert the trajectory information into coded information.

[0063] like Figure 4 As shown, the steps of converting the trajectory information into the coding information by the information processing unit are as follows:

[0064] S401 splits the text in the trajectory information into multiple individual texts;

[0065] S402 sets a single character as a character string to be matched;

[0066] S403 matches the character string to be matched with the character string in the preset character library to obtain a matching result;

[0067] S404 identifies the text corresponding to the to-be-matched character string according to the matching result;

[0068] S405 performs encoding conversion on a single character to obtain corresponding encoding information.

[0069] G-sensor module A203, used to correct and optimize the fineness of writing, and to sense and record information represented by gestures, where the information represented by gestures is pre-specified;

[0070] The G-sensor module A203 records the trajectory information in the form of three-dimensional space storage and transmits the information to the MCU module;

[0071] The communication module A204 includes a wireless communication unit for transmitting the trajectory information to the mobile terminal and / or the server;

[0072] The wireless communication unit is a ZigBee component, a wifi component and / or a Bluetooth component;

[0073] ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. According to international standards, ZigBee technology is a short-range, low-power wireless communication technology, which is characterized by close distance, low complexity, self-organization, low power consumption, and low data rate. It is mainly suitable for use in the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless networking communication technology.

[0074] The power module A205 includes a battery, a charging unit and a discharging unit, and is used to supply power to other modules and to charge and discharge the battery.

[0075] The battery is a lithium battery.

[0076] The power module A205 also includes a switch, which is arranged on the pen body 2;

[0077] The switch is connected to the power module A205 to start the power module A205 or turn off the power module A205.

[0078] The switch can be set as a pressure sensor, which is arranged at the pen head 1, and a certain pressure threshold can be set during design and installation. When the pressure sensor senses pressure, the circuit forwards the pressure as an electrical signal to trigger the switch to turn on so as to start the smart pen; when the pressure sensor does not sense pressure, the switch is automatically turned off to save power.

[0079] In another embodiment of the present invention, under the premise of setting a pressure sensor, a clock can also be set in the circuit, and a certain time can be set so that when the pressure sensor cannot feel the pressure within the time, the switch will not be automatically closed.

[0080] Of course, the switch can also be other switches, such as a touch-sensitive switch. If it is a touch-sensitive switch, when designing and installing it, try to install it in a place where the fingers cannot touch the pen when writing. Technical personnel in this field should know that the switch can also be other functional switches. Of course, when designing and installing it, it should be avoided that the switch is frequently turned on due to accidental touches similar to a touch-sensitive switch. For example, a fingerprint sensing switch should not be installed in the range that can be touched by the fingers when writing.

[0081] The prompt module A206 includes a light to indicate the battery charging status, charging completion status, smart pen startup status, and battery power nearly exhausted status. Each status can be distinguished by the duration of the light or the flashing frequency.

[0082] The prompt module A206 may also include a vibration motor, and of course the vibration motor may be replaced by other vibration devices;

[0083] The vibration motor vibrates when the power module A205 is turned on to indicate the startup status of the smart pen. Of course, the vibration time needs to be set, which is generally 1 second, and can be adjusted according to the situation. In addition, if the smart pen is turned on, the vibration motor can also vibrate for a certain period of time when the battery is close to being exhausted to remind the user to charge in time.

[0085] like Figure 5 As shown, a mobile device according to an embodiment of the present invention is provided, including a communication unit A501, an acquisition unit A502 and a response unit A503;

[0086] The communication unit A501 is used to connect to the smart pen in the first embodiment to obtain the track information;

[0087] The acquisition unit A502 is used to acquire an instruction to view trajectory information;

[0088] The response unit A503 is used to respond to the instruction obtained by the acquisition unit A502 to view the trajectory information and its classification and integration results.

[0089] The mobile device may be any terminal device including a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), a car computer, etc., taking a mobile phone as an example:
