Description

Technical Field

[0001] The present invention relates to the technical field of product display, and specifically to a smart display device.

Background Art

[0002] In the field of commercial display, the "product display cabinet" serves as a bridge connecting products and consumers, and its design layout has an inestimable impact on sales performance. In particular, the height and size of the display position are directly related to the visibility of the product and the sales conversion rate. However, as a long-term issue, although the display area in the middle section can usually maximize the charm of the product, the visual lines in the lower and upper areas are difficult to reach, so it encounters a double困境 in display effect and sales performance, and the significant difference between the two needs to be resolved urgently.

[0003] Eye movement tracking is the process of measuring eye movements. Eye movement technology further studies an individual's internal cognitive process by extracting data such as fixation time, fixation trajectory, and fixation count from the recording of eye movement trajectories. More precisely, image processing technology is performed through instruments to identify the pupil position, obtain coordinates, and calculate the point where the eye fixates or stares through a certain algorithm, so that the computer knows where and when to look. Eye movement-related technology is a popular research direction in the fields of computer vision and human-machine interaction, and the classification of eye movement data is widely applied in fields such as market research. In marketing research, eye movement type tracking is an important means that can objectively reflect consumers' attention and spontaneous feedback to marketing information. Consumers' eye movement data helps marketing personnel study consumers' purchase intention.

[0004] However, efficiently utilizing eye-movement tracking and human motion detection technologies and translating them into actionable display optimization policies remains a technical challenge. More importantly, the market lacks innovative solutions that cleverly combine eye-movement tracking technology with display shelf design to dynamically adjust display content based on consumers' real-time gaze, thereby effectively reducing the difference in display effectiveness between lower and higher levels and comprehensively improving product appeal and sales performance.

[0005] Therefore, we have developed a smart exhibition system that integrates eye movement tracking technology. This system can not only accurately capture consumers' gaze but also intelligently adjust exhibition policies based on eye movement data. In particular, optimizing exhibitions for both low and high-level areas is a technological bottleneck that must be overcome urgently in the current commercial exhibition field, and is key to improving overall exhibition effectiveness and promoting sales. [Overview of the project] [Problems that the invention aims to solve]

[0006] This invention can solve the technical problems in the background technology and provides a smart display device that can track the customer's eye position and product display information and display it to the customer, thereby attracting the customer to the product, increasing its perceived value, and thereby attracting the customer and creating a purchasing impulse. [Means for solving the problem]

[0007] The technical solution of this invention is a smart display device, which includes a frame in which a plurality of display units are provided, each display unit including a fixed space and a movable space for placing products, the movable space is provided with a displacement assembly that is movable within the fixed space, the frame is provided with a sensing assembly, the sensing assembly is connected to the displacement assembly in the movable space and emits a displacement signal to control the displacement assembly, the displacement assembly displaces the movable space forward and backward relative to the fixed space.

[0008] Furthermore, the sensing assembly includes an eye movement tracking camera for tracking and collecting the rotational gaze position of the customer's eyeballs, with a controller and power supply located inside the frame, the eye movement tracking camera mounted connected to the top of the frame, the power supply electrically connected to the controller, eye movement tracking camera and displacement assembly, the controller signal-connected to the eye movement tracking camera and displacement assembly, and when the eye movement tracking camera detects that the user's gaze is fixed on a product for a certain position and duration, the controller emits a displacement signal to trigger the displacement assembly to protrude the movable space of the corresponding product, providing real-time feedback to the user.

[0009] Furthermore, the displacement assembly includes a chute rail symmetrically provided at the bottom of the movable space, and the movable space is displaced by sliding on the chute rail by a provided displacement cylinder.

[0010] Furthermore, an information display device is provided in the movable space, the information display device is hinged to the upper part of the movable space, and the information display device is provided with a reversing mechanism that drives it to rotate by a certain angle.

[0011] Furthermore, the reversing means includes a reversing motor, the output terminal of which is hinged to the information display device, and the reversing motor rotates the information display device by a certain angle.

[0012] Furthermore, the display unit is further provided with a lighting module, which includes an LED lamp strip provided around the front end of the fixed space and a spotlight provided above the movable space, the spotlight facing the merchandise placed in the movable space.

[0013] Furthermore, the sensing assembly includes a weight sensing module located at the bottom of the movable space, and an information display screen located at the top of the frame. The weight sensing module is signal-connected to the information display screen, and when an item in the movable space is lifted and its weight changes, the weight sensing module emits a signal that triggers the information display screen to play an information presentation video of the corresponding item.

[0014] Furthermore, the plurality of display units constitute a display unit layer, and the lower display unit layer of the plurality of display unit layers is arranged to extend outward relative to the upper display unit layer so that the entire apparatus is arranged in a stepped manner.

[0015] Furthermore, the frame includes a back panel and side panels provided on both sides of the back panel. Between the side panels on both sides, multiple multi-stage dividers are provided horizontally to divide the display unit into multiple layers, and multiple divider panels are provided vertically on the multi-stage dividers to divide the display unit into multiple layers.

[0016] Furthermore, multiple of the aforementioned display units are arranged in an array. [Effects of the Invention]

[0017] Compared to conventional technology, the beneficial effects of this invention are as follows:

[0018] 1. Equipped with a sensing assembly and a displacement assembly, and combining eye movement tracking technology with the design of the display shelves, the system detects the customer's gaze position and gaze time through an eye movement tracking camera. When a customer gazes at a product for a certain period of time, the system can attract the customer's attention with dynamic effects such as LED flashing and the protruding display of the displacement assembly, making it easier for customers to observe the product details, avoiding situations where the product is obstructed by the area in which it is placed, and further enhancing the product's appeal. This real-time feedback interaction mechanism stimulates customer purchasing intent, promotes sales conversion, and dynamically adjusts the display content based on the consumer's gaze in real time, thereby effectively reducing the difference in display effect between the lower and upper levels. At the same time, by guiding the customer's gaze to specific products, it improves the display rate and selection opportunity of these products. The display method of this system helps to improve sales efficiency, enhance the customer's shopping experience, and comprehensively improve product appeal and sales performance.

[0019] 2. The sloping design, with the entire device arranged in a stepped pattern, makes it easier to observe and approach products in the lower display areas, effectively reducing the visibility blind spots often seen in conventional display cabinets, allowing products on all levels to be fully displayed and improving the overall display effect.

[0020] 3. By providing a reversing mechanism, this device allows the information display device to be reversed outwards and its angle adjusted, enabling customers to easily view information such as prices and product details while standing. This greatly improves the convenience of shopping, eliminating the need to frequently bend down to see prices. By reversing the price tags, price information is immediately visible, making it easier for customers to make quick selections and improving shopping efficiency. Furthermore, the design that eliminates the need to bend down embodies human consideration for customers, and especially for the elderly, people with disabilities, and those with back problems, this design greatly improves their shopping experience and enhances the store's friendliness and service quality.

[0022] The following aims to clearly and completely describe the concept, specific structure, and resulting technical effects of the present invention with reference to examples and drawings, so as to fully understand the purpose, solution, and effects of the present invention. In addition, when there is no conflict, the examples and features in the present application can be combined with each other.

[0023] In addition, unless otherwise specified, when a certain feature is said to be "fixed" or "connected" to another feature, the feature may be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. Also, descriptions such as "upper", "lower", "left", "right", "top", "bottom", etc. used in the present invention only refer to the relative positional relationship of each component of the present invention in the drawings.

[0024] Furthermore, unless otherwise defined, all technical terms and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the art. The terms used in the description of this specification are only for explaining specific examples and do not limit the present invention. The term "and / or" used in this specification includes any combination of one or more related listed items.

[0025] It should be understood that while terms such as "first," "second," and "third" may be used in this disclosure to describe various types of elements, these elements are not limited to these terms. These terms are used solely to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0026] As shown in Figure 1, Embodiment 1 of the present invention provides a smart display device, which includes a frame containing a plurality of display units, each display unit being an independent space for displaying different products. The interior of the display unit is subdivided into a fixed space 1 and a movable space 2. The fixed space 1 is mainly used for mounting the displacement assembly and providing structural support. The movable space 2 is used to place and display different products and to achieve dynamic display through the displacement assembly. The sensing assembly 3 includes an eye movement tracking camera 4 for tracking and collecting the rotational gaze position of the customer's eyeballs. The eye movement tracking camera 4 captures and analyzes the user's eye movements, identifies the position and duration of the user's gaze, and achieves user eye tracking through a set image processing algorithm program. A controller and power supply are provided inside the frame, and the eye movement tracking camera 4 is mounted connected to the top of the frame. The power supply is electrically connected to the controller, the eye movement tracking camera 4 and the displacement assembly, providing the necessary electrical energy for the entire system and ensuring that all electronic components operate normally. The power supply employs either a DC power supply or an AC / DC power supply system and is equipped with safety measures such as overload protection and short-circuit protection. The controller is signal-connected to the eye movement tracking camera 4 and the displacement assembly, receives data transmitted from the eye movement tracking camera 4, processes and analyzes it, determines the user's gaze position and gaze time based on a preset logic, and sends a control signal to the corresponding displacement assembly to command the execution of a protruding movement. The controller may also be equipped with data processing, storage, and network communication functions for remote monitoring and debugging. For example, if multiple display units are used as a virtual selection area, and the eye movement tracking camera 4 detects that the user's gaze is fixed on a product for a set position and time, it is equivalent to selecting the display unit area corresponding to that product. The controller then emits a displacement signal to trigger the displacement assembly to protrude the movable space 2 of the corresponding product, providing the user with real-time feedback.

[0027] The following describes the basic operating principle of this device. When a user stands in front of the device, the eye movement tracking camera 4 starts operating and continuously monitors and records the user's eye movement trajectory. When the system detects that the user's gaze remains on a product for more than a preset time threshold (e.g., 2 seconds), the controller identifies this action as "interest" and immediately sends a command to the displacement assembly in the movable space 2 of the display unit, thereby causing the movable space 2 to protrude forward, bringing the product closer to the user, thereby providing real-time, intuitive feedback and enhancing the user's sense of engagement and willingness to purchase.

[0028] Furthermore, before sending a command to the displacement assembly, if the system detects that the user's gaze has remained on a particular product for more than a preset time threshold (e.g., 2 seconds), the controller identifies this action as "observation" and issues a command to the lighting module, which can then generate effects such as normally-on, breathing light effects, or color gradients in the lighting module of the display unit corresponding to the "observed" product, further attracting the user's interest in viewing the product. Specifically, as shown in Figure 6, the display unit is further provided with a lighting module, which includes an LED lamp strip 8 provided around the front end of the fixed space 1 and a spotlight 9 provided above the movable space 2, with the spotlight 9 facing the product placed in the movable space 2. The controller is signal-connected to and controls the LED lamp strip 8 and the spotlight 9. For example, when a user gazes at a particular product from a distance, the LED lamp strip 8 at the front end of the fixed space 1 flashes and lights up, and as the user continues to show interest in the product, the spotlight 9 focuses on the product, while the LED lamp strip 8 may adjust to soft background light to emphasize the focus of the display.

[0029] Referring to the schematic diagram of the controller in Figure 7, this represents the basic workflow of this device.

[0030] Initialization: After the system is powered on, each component performs a self-check, the eye movement tracking camera 4 starts up and enters standby mode, and the controller initializes the settings.

[0031] Monitoring phase: The eye movement tracking camera 4 continuously captures and analyzes the user's eye movements and transmits the data to the controller in real time.

[0032] Interest Identification: The controller receives data, analyzes the user's gaze retention location and duration, and determines whether a trigger condition is met. The trigger condition is a pre-set gaze retention time of N seconds, and after N seconds, a pre-set execution signal is sent to the corresponding device to trigger the action. Operation Execution: When a pre-set trigger condition is met, the controller sends a control signal to the displacement assembly of the corresponding display unit, and the movable space 2 protrudes.

[0033] Feedback and Interaction: Users can receive real-time feedback and further observe and interact with products to enhance their shopping experience.

[0034] Reset and Wait: After the user's gaze shifts or after a preset time, the controller instructs the displacement assembly to reset the movable space 2, and the system returns to a monitoring state and prepares to receive the next user or continues to operate by monitoring the user's lingering gaze on other items.

[0035] As shown in Figures 2 and 3, this is Embodiment 2 of the present invention, in which the displacement assembly is installed between the movable space 2 and the fixed space 1 and plays the role of driving and moving the movable space 2 according to the commands of the controller. The displacement assembly includes displacement methods such as rotational displacement, tilting displacement, vertical displacement, extension / contraction displacement and translational displacement. In this embodiment, extension / contraction displacement is preferred. The displacement assembly during extension / contraction may take the form of an electric push rod, a combination of a servo motor and transmission means or a pneumatic / hydraulic system, etc., to ensure that the movable space 2 can stably and accurately extend or retract. Preferably, the displacement assembly includes a chute rail 5 provided symmetrically at the bottom of the movable space 2, and the movable space 2 is slidably displaced on the chute rail 5 by a displacement cylinder provided.

[0036] The other methods for realizing the displacement assemblies described above are briefly explained below.

[0037] 1) Rotational displacement is performed to mount a rotating mechanism, such as a motor-driven rotary table or turntable, within the movable space 2 of the display unit. When the user's gaze is fixed on a product, the controller issues a command to drive the rotating mechanism to rotate and display the product, presenting details of the product from multiple angles.

[0038] 2) A tilt adjustment mechanism, such as a tilt hydraulic rod or tilt motor, is attached to the bottom of the movable space 2 of the display unit by tilting it. When the user's gaze is fixed on the product, the controller controls the tilt mechanism to tilt the product to a certain angle, making it easier for the user to observe the product from a more comfortable viewpoint.

[0039] 3) Lifting and lowering means, such as a screw elevator, air cylinder, or hydraulic cylinder, are installed below the movable space 2 of the display unit. When the user's gaze is fixed on a product, the controller controls the lifting and lowering means to raise the product vertically or lower it by a certain distance, tiering the products to attract the user's attention and making it convenient for the user to observe the product details up close.

[0040] 4) A linear guide rail and slider mechanism are attached below the movable space 2 of the display unit via translational displacement. Translation is achieved by driving a motor or cylinder. When the user's line of sight remains in a certain area, the controller controls the translation mechanism to translate the movable space 2 of the adjacent display unit into the user's line of sight, enabling rapid product changeover displays. Translational displacement can quickly respond to points of interest for the user, improve display efficiency, and enhance the user's interactive experience.

[0041] As shown in Figures 1 to 4, this is Embodiment 3 of the present invention, in which an information display device 6 is provided in the movable space 2. The information display device 6 is a display medium consisting of a display screen, a projection screen, or a cardboard display medium for displaying price and product information, and is used to convey visual information to a user standing in front of the device, making it easy for the user to quickly and in detail learn about the status of the products. The information display device 6 is hinged to the upper part of the movable space 2 and is provided with a reversing means that drives it to rotate by a certain angle.

[0042] As shown in Figures 2 and 3, this is Embodiment 4 of the present invention, in which the reversing means plays a role in driving the rotational movement of the entire display device. Preferably, the reversing means includes a reversing motor 7, the output terminal of which is hinged to the information display device 6, and the reversing motor 7 rotates the information display device 6 by a certain angle, allowing customers to easily view information such as prices and product details while standing, greatly improving the convenience of shopping, eliminating the need to frequently bend down to see prices, and making price information immediately visible by reversing the price tags, making it easier for customers to make quick selections and improving shopping efficiency. Furthermore, the design that eliminates the need to bend down embodies human consideration for customers, and especially for elderly people, people with disabilities, and people with back problems, this design greatly improves their shopping experience and enhances the store's friendliness and quality of service.

[0043] Furthermore, a reducer, a transmission, and a controller are provided as needed to precisely control the angle and speed of rotation. A distance sensor may be provided in the reversing means. When the user is at a preset distance from the device, the distance sensor sends a command to the controller, which, upon receiving the command, analyzes and converts it into a corresponding electrical signal, which is then transmitted to the motor of the reversing means. The motor receives the signal and starts operating, adjusting the rotational speed and torque via the reducer, and then transmits power to the hinge structure via the transmission (gears, chain, etc.), thereby rotating the information display device 6 around the hinge point.

[0044] Furthermore, the reversing mechanism may be equipped with angle sensors to monitor the angle and position of the device in real time and ensure the accuracy and stability of rotation. These sensors feed back real-time data to the controller, forming a closed-loop controller and further improving the accuracy and response speed of adjustment.

[0045] As shown in Figure 4, this is Embodiment 5 of the present invention, in which the sensing assembly 3 includes a weight sensing module (not shown) provided at the bottom of the movable space 2. The weight sensing module may consist of a pressure sensor or a weighing sensor and can accurately measure the total weight of the goods placed in the movable space 2. An information display screen 10 is provided at the top of the frame, and the weight sensing module is signal-connected to the information display screen 10. When goods in the movable space 2 are lifted or returned, the weight sensing module detects the change in weight. This change is converted into an electrical signal and transmitted to the controller of the information display screen 10 via the signal connection. When the controller of the information display screen 10 receives the signal from the weight sensing module, it performs signal processing and identification. By a pre-configured algorithm or database matching, the controller can identify which goods have been picked up and determine the information presentation video corresponding to those goods. These videos may include product introductions, usage instructions, pricing, promotional information, etc., and are intended to attract customer attention and promote sales.

[0046] In addition to the weight-sensing embodiment described above, it is also possible to detect the movement or presence of an object using an infrared sensor, similar to infrared sensing technology. Using image processing and computer vision technology, when an object blocks or reflects infrared light, the sensor receives a change in signal and triggers a corresponding action. A camera is used to capture an image within the movable space 2, and a computer vision algorithm is used to analyze the image content and identify the lifted product.

[0047] As shown in Figures 2 and 3, the multiple display units constitute a display unit layer, and the lower display unit layer of the multiple display unit layer extends outward relative to the upper display unit layer so that the entire apparatus is arranged in a stepped manner. The sloping design in which the entire apparatus is arranged in a stepped manner makes it easier to observe and approach the products in the lower display area, effectively reduces the vision blind spot problem often seen in conventional display cabinets, allows for sufficient display of products on all levels, and improves the overall display effect. The spaces between the display units and display unit layers do not need to be partitioned by the physical structure of the entities, and may be partitioned in a way that makes them appear to float in mid-air, for example.

[0048] As shown in Figure 5, specifically in this embodiment, the display unit and the display unit layer depend on the display shelf, the display shelf includes a frame, and the frame, as the main support structure of the entire display device, is made of a strong and beautiful material such as a metal alloy or high-strength plastic to ensure stability and durability. The frame design accommodates multiple display units and employs a multi-tier or partition design to consider the display effect and space utilization rate. The frame includes a back plate 11 and side plates 12 provided on both sides of the back plate 11, and multiple multi-tier dividers 13 are provided horizontally between the side plates 12 on both sides to partition into multiple display unit layers and realize a multi-tier design, and multiple partition plates 14 are provided vertically on the multi-tier dividers 13 to partition into multiple display units and realize a partition design.

[0049] As shown in Figure 1, multiple exhibition units are arranged in an array. The array arrangement includes linear array layouts, mesh array layouts, circular array layouts, spiral linear layouts, and polygonal layouts, forming a layout with geometric aesthetics and a sense of space. The specific form of the array arrangement is determined by comprehensively considering factors such as the exhibition content, spatial size, direction of visitor movement, and design objectives, and a combination of various layout forms must be used to create a unique exhibition effect.

[0050] The foregoing describes only preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure, as long as they achieve the technical effects of the present invention by the same means, should be included within the scope of protection of this disclosure. All such modifications and changes should fall within the scope of protection of the present invention.
