With the increasingly diverse and personalized consumer demands, the traditional sales model is becoming increasingly difficult to meet the dynamic changes in the market. On the one hand, when facing a vast amount of product information and complex customer needs, salespersons often fall into the dilemma of information overload and are difficult to quickly and accurately match suitable products for customers, resulting in low sales efficiency.

[0003] On the other hand, customers expect to obtain a more intuitive and immersive shopping experience. Simple oral introductions and static displays can no longer fully stimulate the desire to purchase. They are eager to deeply perceive the actual use effects of products before purchase. Moreover, the issue of data security is becoming increasingly prominent in the sales scenario. The transaction process involves a large amount of customer privacy and business secrets, from customer identity information to sales order details. Once leaked, it will cause huge losses to both parties. At the same time, the sales environment is complex and changeable. Magnetic field interference in different venues, hiding of potential dangerous items, etc. require the device to have a sensitive environmental perception ability. Wearable sales assistance devices and their control systems have emerged as the times require.

Obviously, the drawings described below are merely exemplary, and for those of ordinary skill in the art, without creative efforts, other implementation drawings can be obtained based on the provided drawings.

[0044] Figure 1 It is a structural diagram of a wearable sales assistance device. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] The drawings are only for exemplary illustration and cannot be construed as a limitation to this patent;

[0046] For better illustration of this embodiment, some components in the drawings are omitted, enlarged, or reduced, and do not represent the actual size of the product;

[0047] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0048] The following will further explain the technical solutions of the present invention in conjunction with the drawings and embodiments.

[0049] Embodiment

[0050] A wearable sales assistance system, as Figure 1 shown, includes:

[0051] A multimodal interaction perception module, which is used to realize user intention recognition, identity authentication, action capture and odor detection data through a brain-computer interface, biometrics, a MEMS inertial sensor array and an electronic nose;

[0052] A security guarantee module, which is used to ensure the security of data transmission through quantum encrypted communication and monitor and prevent potential security threats through an intrusion detection and early warning system;

[0053] A display enhancement module, which includes light field display technology and VR / AR fusion technology, and is used to provide immersive sales displays and augmented reality information superposition;

[0054] An intelligent optimization module, which is used to analyze sales data and optimize sales strategies and product recommendations;

[0055] An environment perception module, which integrates a quantum magnetometer and terahertz detection technology, and is used to perceive magnetic field changes and material composition in the sales environment.

[0056] The multimodal interaction perception module includes:

[0057] A brain-computer interface sub-module, which uses electrode sensors to fit relevant parts of the human head, collects electrical signals generated by the activities of brain neurons, and converts them into digital signals through a signal processing circuit for identifying instructions related to the user's thinking intention;

[0058] The salesperson wears a helmet equipped with high-precision electrode sensors, which closely fits key parts of their head, such as areas of the forehead and temporal lobe. These sensors can keenly capture the weak electrical signals generated by the activities of brain neurons. When the salesperson is communicating with a customer and the customer mentions the performance requirements for a certain tablet computer, the salesperson's brain quickly thinks about how to demonstrate the advantages of the product. At this time, the electrode sensors collect relevant electrical signals in real time and convert them into clear digital signals through the built-in signal processing circuit, and the system identifies the intention instruction for the salesperson to retrieve the detailed performance parameter display materials of the tablet computer.

[0059] A biometric sub-module, which obtains unique biometric identification information of an individual through various biometric acquisition technologies to achieve identity discrimination;

[0060] When the sales staff clock in at the store in the morning, the iris recognition unit at the door is activated, and a high-resolution camera is used to quickly capture the sales staff's iris image. Through advanced image processing algorithms, the iris texture features are accurately extracted and encoded to generate unique feature data, which is compared with the store's employee database to complete identity authentication, ensuring that only authorized employees can use the system.

[0061] During the sales process, the smart bracelet worn on the salesperson's wrist serves as the carrier of the physiological monitoring unit, which continuously collects the values ​​of his heart rate, blood pressure and other physiological parameters. For example, when the salesperson receives multiple customers in succession, he appears slightly tired and his heart rate rises, the system detects this situation and automatically adjusts the subsequent reception process, appropriately reducing the high-intensity product demonstration process to avoid excessive fatigue of the salesperson and affecting the service quality.

[0062] The MEMS inertial sensor array submodule consists of multiple micro inertial sensors, which detect the acceleration and angular velocity data of the human body in different axes, and analyze the changes in human body motion posture through internal algorithm integration;

[0063] The special vests worn by sales staff have built-in MEMS inertial sensor arrays. Multiple micro inertial sensors are distributed in different positions of the vest, which can accurately detect the acceleration and angular velocity data of the human body in the three axes of X, Y, and Z. When the salesperson demonstrates a virtual reality game device to the customer, he quickly turns around, raises his hands, and other movements. The sensor array captures these movement changes in real time, and through internal complex algorithm integration and analysis, it accurately determines the salesperson's movement posture, and then controls the virtual character on the display device to make the same movement synchronously, allowing customers to more intuitively feel the operating effect of the product.

[0064] The electronic nose module has multiple gas sensors built in. Different gas sensors produce different electrochemical reactions to various odor components in the environment, and the odor components and their concentrations are detected by converting the reaction strength into corresponding electrical signals.

[0065] The electronic nose module installed in the experience store has a variety of highly sensitive gas sensors built in. When coffee overflows from the coffee area in the store and a rich coffee aroma fills the air, the different gas sensors in the electronic nose module undergo an electrochemical reaction with the coffee odor components, which are converted into corresponding electrical signals based on the strength of the reaction. The odor components and their concentrations are quickly detected, and the system then automatically triggers the ventilation equipment to enhance ventilation, keeping the air in the store fresh and creating a comfortable shopping environment for customers.

[0066] The biometric identification submodule includes:

[0067] The iris recognition unit uses a high-resolution image acquisition device to obtain a human eye iris image, extracts and encodes the iris texture features, and generates feature data for comparison and recognition.

[0068] The physiological monitoring unit uses wearable sensors to collect real-time human physiological parameter values.

[0069] The security guarantee module includes:

[0070] The quantum encryption communication sub-module, based on the entanglement characteristics of quantum states, configures a quantum key generation device at the communication end to generate a quantum key pair to encrypt the transmitted data, ensuring the confidentiality of the data in the communication link.

[0071] When the salesperson uses the wearable system to upload sensitive sales data such as the customer's purchase intention and personal preferences to the in-store back-end server, at the communication end, the quantum key generation device configured based on the entanglement characteristics of quantum states quickly generates a quantum key to perform high-strength encryption processing on the transmitted data. Even in a complex in-store wireless network environment, if a hacker attempts to intercept the data, due to the extremely high security of quantum encryption, the hacker cannot crack the encrypted information, ensuring the confidentiality of the customer data in the communication link and effectively protecting the customer's privacy.

[0072] The intrusion detection and warning sub-module sets up a monitoring program in the system to monitor the access requests and data read / write operation behaviors of network ports in real time, compares the real-time monitoring results with a preset normal behavior pattern library, and triggers a warning mechanism to send a warning message when abnormal behaviors are found.

[0073] The monitoring program in the system runs continuously for 24 hours to monitor the access requests and data read / write operation behaviors of network ports in real time. When the in-store network is subjected to malicious scans from unknown external sources, the monitoring program immediately compares the real-time monitoring results with the preset normal behavior pattern library, instantly discovers abnormal behaviors, and immediately triggers the warning mechanism, not only sending a warning message to the salesperson's wearable device, but also notifying the in-store security personnel and IT technical support to take timely measures to resist the intrusion and ensure the safe and stable operation of the system.

[0074] The display enhancement module includes:

[0075] The light field display sub-module constructs a microlens array light control structure inside the display device to modulate the light emitted by the light source from multiple angles and directions. By controlling the light propagation path and intensity distribution, a light field image with spatial three-dimensionality is reconstructed for display.

[0076] When a salesperson introduces a smart watch to a customer, the light field display sub-module in the smart glasses he wears is activated. Inside the glasses, the microlens array light modulation structure exquisitely modulates the light emitted by the built-in light source at multiple angles and in multiple directions. By precisely controlling the light propagation path and intensity distribution, a light field image with a realistic spatial three-dimensional sense is reconstructed, presenting the internal fine structure and operating principle of the smart watch in 3D form in front of the customer's eyes, enabling the customer to deeply understand the product details without the need to rely on complex tools.

[0077] The VR / AR fusion sub-module utilizes the image rendering unit and spatial positioning and tracking unit components related to VR and AR. It uses the spatial positioning and tracking unit to obtain the real-space position and pose information of the user's head or eyes, and then combines with the image rendering unit to perform fusion rendering of virtual content according to the user's perspective, and outputs the fused image for display on the display device.

[0078] When a customer is interested in the newly stocked smart home system in the store, the salesperson guides the customer to put on a display helmet with the same VR / AR fusion function. The spatial positioning and tracking unit built into the helmet is used to obtain the real-space position and pose information of the customer's head. The image rendering unit, according to the customer's perspective, perfectly fuses and renders virtual smart home scenarios, such as the effect of smart lights changing at will and remote control of home appliances, with the real exhibition hall environment, and outputs the shocking fused image for display on the helmet screen, making the customer feel as if they are in a future smart home life scenario, greatly enhancing the customer's desire to purchase.

[0079] After business hours, the intelligent optimization module of the system automatically summarizes all the sales data of the day, including the customer's attention to different products, inquiry frequency, purchase conversion rate, etc. Through in-depth data analysis, it is found that in the past week, the customer's attention to electronic products with health monitoring functions has been continuously rising, but the display position of related products in the store is not prominent, resulting in a low purchase conversion rate. Based on the analysis results, the system automatically optimizes the sales strategy, adjusts the product display layout, moves the health monitoring electronic products to the core position of the exhibition hall, and generates targeted product recommendation scripts for the salesperson to highlight the product features, providing strong support for subsequent sales work.

[0080] The environmental perception module includes:

[0081] The quantum magnetometer sub-module constructs a quantum magnetic induction probe based on the quantum coherence and tunneling effects. The probe is placed in the sales environment to sense the changes in the surrounding magnetic field strength and direction, and converts the sensed physical quantities of the magnetic field strength and direction into electrical signals for output detection;

[0082] Some areas in the experience store display electronic products sensitive to magnetic fields, such as high-precision electronic compasses, etc. The quantum magnetometer sub-module has quantum magnetic induction probes constructed based on quantum coherence and tunneling effects, which are distributed around the display cabinets of these products. Once a customer approaches with a strongly magnetic item, such as a magnetic phone holder not properly stored, the probes quickly sense the change in the magnetic field strength and direction around them, convert the sensed physical quantities of the magnetic field strength and direction into electrical signals for output detection, and the system immediately issues an alarm to remind the customer to properly store the magnetic item to avoid damage to the exhibits.

[0083] The terahertz detection sub-module is equipped with a terahertz wave emission source to emit terahertz waves of a specific frequency into the sales environment. At the same time, a terahertz wave receiving device is set up to receive the terahertz waves reflected or transmitted by objects in the sales environment, and analyze the changes in the frequency, phase, and amplitude parameters of the received terahertz waves to detect the object characteristics and environmental conditions.

[0084] The terahertz wave emission source equipped in the terahertz detection sub-module regularly emits terahertz waves of a specific frequency to every corner of the store. At the same time, the terahertz wave receiving device is on standby at any time. When the wooden structure of a display cabinet in the store shows slight moisture-induced deformation, after the terahertz waves are reflected by the moisture-affected part, the receiving device analyzes the changes in the frequency, phase, and amplitude parameters of the received terahertz waves, accurately detects the abnormalities in the object characteristics and environmental conditions, and the system promptly notifies the maintenance personnel to come for inspection and repair to ensure the safety of the display cabinet and exhibits.

[0085] A control system includes:

[0086] A control center unit, which is respectively connected to the multi-modal interaction perception module, the security guarantee module, the display enhancement module, the intelligent optimization module, and the environmental perception module, and is used to coordinate the data transmission and instruction execution between the modules;

[0087] A data processing unit, which is used to receive and process the data from the brain-computer interface sub-module, the biometric recognition sub-module, the MEMS inertial sensor array sub-module, and the electronic nose module of the multi-modal interaction perception module, as well as the data from the quantum magnetometer sub-module and the terahertz detection sub-module of the environmental perception module;

[0088] A security monitoring unit, which is used to execute the functions of the quantum encryption communication sub-module to protect the security of data transmission, and execute the functions of the intrusion detection and early warning sub-module to monitor and prevent potential security threats;

[0089] A user interface unit, which is used to display the images generated by the light field display sub-module and the VR / AR fusion sub-module in the display enhancement module and provide a user interaction interface;

[0090] An intelligent analysis unit for analyzing sales data and optimizing sales strategies and product recommendations based on the analysis results;

[0091] A power management unit for monitoring and optimizing the energy consumption of the system to ensure the stable operation of the system;

[0092] A fault diagnosis unit for detecting the status of each module of the system, identifying faults, and providing corresponding solutions.

[0093] An electronic device, comprising:

[0094] A memory storing executable program code;

[0095] A processor coupled to the memory;

[0096] The processor calls the executable program code stored in the memory and executes a wearable sales assistance system as described above.

[0097] In a specific implementation, the control center unit coordinates data transmission and instruction execution between modules. In each link of the above sales scenario, it receives data from various modules such as the multi-modal interaction perception module and the environment perception module in real time, judges the importance and urgency of the data according to the preset logic, and sends instructions to the corresponding modules. For example, after receiving the action data of the salesperson reaching for the model from the MEMS inertial sensor array sub-module, it quickly instructs the display enhancement module to prepare to display the corresponding information of the model; after receiving the encryption completion signal from the quantum encryption communication sub-module, it commands the data to be transmitted to the background server.

[0098] The data processing unit receives and processes data from the brain-computer interface sub-module, biometric recognition sub-module, MEMS inertial sensor array sub-module, and electronic nose module of the multi-modal interaction perception module, as well as data from the quantum magnetometer sub-module and terahertz detection sub-module of the environment perception module. It normalizes these multi-source heterogeneous data, extracts key features, classifies and stores the processed data for the intelligent analysis unit, control center unit, etc. to call at any time. For example, it organizes and archives the identity confirmation data of the biometric recognition sub-module to facilitate subsequent query of employees' work records; it preliminarily analyzes the magnetic field and object characteristic data of the environment perception module and marks abnormal data points.

[0099] On the one hand, the security monitoring unit executes the functions of the quantum encryption communication sub-module to protect the security of data transmission. On the other hand, it executes the functions of the intrusion detection and early warning sub-module to monitor and prevent potential security threats, ensuring the generation, distribution, and update of quantum encryption keys throughout the data transmission process and real-time monitoring of the network status. At the same time, it audits the access logs within the system. If suspicious login attempts or data access behaviors are detected, emergency measures such as blocking accounts and cutting off network connections are immediately taken, and relevant personnel are notified.

[0100] The user interface unit is used to display the images generated by the light field display sub-module and the VR / AR fusion sub-module in the display enhancement module, providing a user interaction interface. Through this interface, salespersons can intuitively see various auxiliary information and also receive system prompts, warnings, etc. The interface design is simple and intuitive, facilitating salespersons to quickly obtain key information during the busy sales process. For example, potential security risks are prompted with eye-catching icons, and key recommended models are highlighted with dynamic light and shadow.

[0101] The intelligent analysis unit deeply analyzes sales data and optimizes sales strategies and product recommendations based on the analysis results. In addition to the regular daily and weekly sales data analysis, it can also conduct multi-dimensional comprehensive analysis according to factors such as seasons and market dynamics. For example, before the peak season of auto shows, it analyzes the changing trends of customers' interest preferences during past auto shows, formulates personalized product recommendation scripts for salespersons in advance, and adjusts the suggestions for the exhibition hall display layout to improve sales efficiency.

[0102] The power management unit continuously monitors and optimizes the energy consumption of the system to ensure the stable operation of the system. According to the working loads of each module, battery power, etc., it dynamically adjusts the power supply strategies of the modules. During peak sales periods, it preferentially ensures the power supply of key modules such as the multi-modal interaction perception module and the display enhancement module. When the system is in the standby state or the battery power is low, it automatically turns off some non-essential functions, such as reducing the display brightness and pausing part of the data collection, to extend the single-use duration of the system.

[0103] The fault diagnosis unit regularly detects the status of each module of the system, identifies faults, and provides corresponding solutions. For example, it performs a signal integrity detection on the electrode sensors of the brain-computer interface sub-module every hour. If abnormal signal fluctuations are found, it is judged that the sensors may be loose or affected by electromagnetic interference, and the salespersons are promptly notified to check the wearing situation of the sensors. At the same time, operation guides for shielding interference sources and recalibrating the sensors are given to ensure the reliability of the system.
