[0051] The voice recognition circuit is connected with the master control chip, the voice recognition circuit collects audio signals after processing and sends the audio signals to the master control chip, and the master control chip controls the laser and the computer according to the received audio signals;

[0052] The indicating laser lamp 3 and the positioning laser lamp 4 are respectively driven by corresponding circuits and are controlled by the master control chip;

[0053] The state indicating lamp 1 is connected with the master control chip and is controlled by the master control chip to display the working state of the equipment.

[0054] The utility model specific function uses:

[0055] I. The use process of the positioning indication function:

[0056] When you need to use the positioning indication function, first find the power switch 12 on the laser touch pen, and turn it to the on state, at this time, the laser pen starts, the power management circuit starts to supply power to the internal circuit modules, the master control chip initializes, and the equipment enters the operable state.

[0057] Find the mode button 9, slide it to the position corresponding to the start of the laser light. The operation will trigger the button group circuit to send a signal to the main control chip, and after the main control chip receives the signal, it controls the indication laser circuit and the mouse positioning laser circuit to start, thereby turning on the indication laser light 3 and the mouse positioning laser light 4.

[0058] With the start of the laser light, the status indicator light 1 will also light up accordingly, prompting the user that the laser light is working normally. Among them, the light emitted by the indication laser light 3 is used to clearly indicate the key points of the display content, and the mouse positioning laser light 4 is used to realize the cursor interaction with the display device.

[0059] Hold the laser pen and move it naturally in the air to project the laser point on the wall or display screen. The light emitted by the positioning laser light 4 is reflected by the wall or screen, and the signal receiver (using computer vision sensing positioning technology) captures the reflected light signal and converts it into an electrical signal to transmit to the main control chip. The main control chip calculates the position change of the laser pen according to the received signal, and then sends control instructions to the display device through the wireless signal processing circuit and the wireless amplification circuit, so that the mouse cursor on the display device moves following the movement of the laser point, realizing precise positioning and indication operation.

[0060] II. Use process of page turning function.

[0061] Similarly, turn on the power switch 12, start the laser pen, and complete the initialization and power supply preparation of the device.

[0062] Slide the mode button 9 to the position to turn off the laser light, and the button group circuit will transmit this signal to the main control chip. The main control chip controls the indication laser circuit and the mouse positioning laser circuit to stop working, and turns off the indication laser light 3 and the mouse positioning laser light 4, to avoid laser interference with the visual effect of page turning operation.

[0063] When page turning operation is needed, press the up button 5 or the down button 6. After the button is pressed, the button group circuit generates a corresponding electrical signal and transmits it to the main control chip. The main control chip identifies the signal type and determines whether it is an up or down instruction, and then sends a page turning control instruction to the display device (such as a computer, a projector, etc.) paired with the laser pen through the wireless signal processing circuit and the wireless amplification circuit. After the display device receives the instruction, it performs the corresponding page turning operation, realizing the up and down page turning of documents, presentation materials, etc.

[0064] III. Use process of brightness adjustment function.

[0065] Turn on the power switch 12, start the laser pen, and ensure that the device is operating normally and in an operable state.

[0066] Slide the mode switch to the position to turn on the laser light, so that the indication laser light 3 and the mouse positioning laser light 4 are turned on, providing a basis for brightness adjustment operation.

[0067] Press the menu button 10, which sends a signal to the main control chip through the button group circuit. After receiving the signal, the main control chip controls the communication with the display device (such as a connected computer display screen), and a settings menu pops up on the display screen. Then, by pressing the up button 5 or the down button 6, the user selects the brightness adjustment menu option in the settings menu. The button group circuit transmits the user's selection signal to the main control chip, which highlights the brightness adjustment menu option on the display screen according to the received signal.

[0068] Press the menu button 10 again to confirm the selection of the brightness adjustment menu. After receiving the confirmation signal, the main control chip enters the brightness adjustment control mode.

[0069] By continuously pressing the up button 5 or the down button 6, the main control chip receives the brightness adjustment signal. According to the received signal, the main control chip controls the laser light driving circuit to change the current size of the indicator laser light 3 and the mouse positioning laser light 4, thereby adjusting the brightness of the laser light. The user can observe the brightness change of the laser light in real time, and click the menu key to confirm when the appropriate brightness is reached. After receiving the confirmation signal, the main control chip saves the current brightness setting and completes the brightness adjustment operation.

[0070] Four, the use process of voice recognition function.

[0071] Turn on the power switch 12 to start the laser pen. After the device completes initialization and self-checking, each circuit module enters a normal working state, and the voice recognition circuit also starts to be in a listening state.

[0072] After the laser pen is started, the user clearly calls "Little treasure, hello". The voice recognition circuit collects the user's voice signal, uses the built-in high anti-interference chip to perform noise reduction, filtering and other preprocessing on the voice signal, and then transmits the processed signal to the main control chip. After receiving the signal, the main control chip performs matching recognition through the pre-stored voice recognition algorithm and voice library, and confirms that it is a wake-up instruction. The voice playback circuit is controlled to respond "Master, hello! What do you need help with?"

[0073] When the user needs to turn on the positioning laser light 4, directly say "turn on the positioning laser light". The voice recognition circuit collects and processes the voice signal again and transmits it to the main control chip. After recognizing the voice instruction, the main control chip controls the positioning laser circuit to start and turn on the positioning laser light 4.

[0074] For other voice instructions, such as "turn off the indication laser light", "next page", "return to the previous page", etc., the operation process is similar. After the user speaks the instruction, the voice recognition circuit collects, processes and transmits the signal to the main control chip, the main control chip recognizes the instruction, controls the corresponding circuit module or sends the instruction to the display device through the wireless signal processing circuit and the wireless amplification circuit, and realizes the voice control operation of the laser pen and the display device.

[0075] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
