[0003] In the current self-service ordering implementation scheme, a common method is to use the user's mobile phone to scan the QR code at the table to enter the restaurant's ordering system. Although this method is convenient and fast, it also has some significant technical challenges and user experience issues, as follows:

[0004] First, the display page for mobile phone scan code ordering is relatively small, and usually only limited information about dishes can be displayed within a limited screen space. This is undoubtedly a huge challenge for restaurants with many special dishes. Limited display space makes it impossible for restaurants to fully and detailedly introduce each dish, including its ingredients, cooking methods, taste characteristics, etc., which may affect customers' choice and understanding of dishes, resulting in wrong orders or orders that do not meet expectations. At the same time, due to the lack of direct communication with service staff, users may not be able to get answers and help in time, causing confusion and misunderstanding among users.

[0040] like Figure 1-4 As shown, the utility model provides a food ordering projection system, comprising: a dining table 1, a projection device 2 and a background server 3; the projection device 2 is installed directly above the dining table 1; the background server 3 is communicatively connected to the projection device 2; wherein, the projection device 2 comprises: an optical engine module 22, a control module 21, and a gesture touch interaction module 23; the control module 21 is respectively connected to the optical engine module 22 and the gesture touch interaction module 23; the control module 21 is communicatively connected to the background server 3.

[0041] The meal ordering projection system of the utility model includes a dining table 1, a projection device 2 and a backend server 3. The control module 21 in the projection device 2 performs image segmentation, decoding, scaling, color correction and other processing on the customized interactive interface to ensure the quality and display effect of the interactive interface. According to the processed interactive interface, the control module 21 generates a series of control signals and sends them to the optical engine module 22. The optical engine module 22 makes corresponding adjustments and operations according to the received control signals to generate the final displayed interactive interface, and projects the final displayed interactive interface into partitions on the dining table 1, which can display a rich interactive interface in a larger display space, has a sufficient sense of technology, increases the customer's sense of interaction, and supports multiple people to operate simultaneously. The gesture touch interaction module 23 can capture the customer's gestures and movements, and convert the captured gestures and movements into electronic signals, which are transmitted to the backend server 3 through the control module 21. The backend server 3 generates order information by analyzing the received electronic signals, so that customers can operate and make choices directly on the dining table 1 without using mobile phones or other devices. As long as the customers sit down at the dining table, they can enter the ordering mode, and it supports simultaneous operation by multiple people, avoiding the customers' dining experience being affected by problems such as insufficient mobile phone power or poor signal, saving customers' time, improving the restaurant's service efficiency, creating an immersive dining experience, allowing customers to be more involved in and enjoy the dining process, enhancing the restaurant's image and competitiveness, and can be applied to a variety of scenarios.

[0042] In this embodiment, the customized interactive interface can be an interactive screen built into the memory of the control module 21, or an interactive screen received from an external device (such as a computer, a video player, etc.). The interactive screen includes image pixel data, color information, brightness, contrast and other parameters. This is not limited in this embodiment and is selected according to actual needs.

[0043] In this embodiment, the customized interactive interface includes but is not limited to: interactive screens for ordering needs in the catering industry, interactive screens for children's learning and entertainment, interactive screens for restaurant culture, interactive pages for counter operations, etc., which can be customized according to the actual use scenario, and the multi-screen switching display can be realized through the projection device 2. In this way, the menu, dish pictures, interactive games and other elements can be directly presented on the dining table 1 through the ordering projection system of the utility model, and customers can directly operate and select on the dining table 1 without using mobile phones or other devices, which can create an immersive dining experience and allow customers to be more involved and enjoy the dining process. In addition, through interactive ordering through projection, different interactive screens can be projected for customers to operate, and customers can interact with the projected content through touch, gestures, etc., such as sliding to browse the menu, clicking to select dishes, etc., which not only increases the fun of dining, but also enables customers to understand the dish information more clearly and improve the efficiency of ordering. Through the ordering projection system of the utility model, information such as the culture, history, and special dishes of the restaurant can also be displayed to provide customers with more personalized services and enhance customers' cognition and favorability of the restaurant.

[0044] In this embodiment, if Figure 2 , 3 As shown, the customized interactive interface is processed by the control module 21 and then displayed by the optical engine module 22 in partition projection, and the number of partitions displayed is 2 or more groups. For example, taking the projected interactive screen of ordering demand as an example, Figure 2 , 3 As shown, in the area shown by the projection area 5, four groups of interactive interfaces 6 can be projected on the dining table 1 by the projection device 2. After the interactive screen of ordering needs is displayed, the gesture touch interaction module 23 can capture the customer's ordering gestures and order confirmation actions and convert them into electronic signals and transmit them to the background server 3. The background server 3 obtains the ordering information by analyzing the received electronic signals, generates order information based on them and implements the meal preparation operation. When the meal preparation operation is completed, just click the corresponding completion on the background server 3, thereby realizing the closed-loop operation of the entire meal ordering system.

[0045] It should be noted that the ordering projection system of the utility model is a hardware system, and each of its internal components is also a hardware component. On this basis, some existing software or programs are used to realize the image segmentation, decoding, scaling, color correction of the interactive interface, and the corresponding adjustment and operation of the control signal, so as to realize the projection display interactive technology of the ordering projection system. However, the utility model itself does not involve any software technology update.

[0046] In this embodiment, the ordering projection system further includes a power supply device 4, which is connected to the projection device 2. The power supply device 4 provides power to the projection device 2. After the projection device 2 receives the power signal, it performs a power-on action. At this time, the power supply of the background server 3 is also in the on state, and the ordering projection system is activated. After 1 minute, the system orders normally, and the customized interactive interface 6 is projected onto the dining table 1 by partition through the projection device 2. The relevant display functions preset in the projection device 2 will also be displayed normally at this time. The displayed area can be displayed as 2 groups or 4 groups, or even more groups at the same time for different customers to order, depending on the actual use of the restaurant. After the ordering page is displayed, the gesture touch interaction module 23 is used to complete the ordering operation.

[0047] In this embodiment, the control module 21 includes: a main control chip, and a memory connected to the main control chip. The main control chip integrates a central processing unit (CPU), a graphics processing unit (GPU), a memory and other key components, and is responsible for executing tasks such as the operating system, application programs and data processing of the projection device 2. The memory can store built-in interactive images, temporary data and running applications.

[0048] In this embodiment, if Figure 4 As shown, the projection device 2 can project the customized interactive interface 6 with a preset light output angle 7 and a preset gesture interaction function window area 8 onto the scene to be displayed, and realize human-computer interaction in combination with its gesture interaction function. Therefore, the projection device 2 can be applied to a variety of occasions.

[0049] In this embodiment, the optical engine module 22 includes a light source, a fully transmissive collimator, a color wheel, a digital micromirror device (DMD), a lens and a lens. The control signal generated by the control module 21 can directly control the brightness of the light source, the rotation speed of the color wheel, the imaging of the digital micromirror device, etc.

[0050] In this embodiment, the light source is an LED light source to ensure the brightness and clarity of the interactive interface. The light source is used to generate light and project the generated light onto the total transmission collimator.

[0051] In this embodiment, the fully-transmitting collimator is used to receive the light emitted by the light source and convert it into a parallel light beam, thereby ensuring that the light maintains directionality during the subsequent propagation process, reducing light loss and evenly projecting the light onto the color wheel and passing through the color wheel.

[0052] In this embodiment, the color wheel is a rotating device for generating different colors. When the parallel light beam from the fully-transmitting collimator passes through the color wheel, the color wheel adds a specific color to the light beam according to the control signal. The color wheel is composed of filters of multiple colors such as red, green, and blue (RGB), providing colors for each imaged pixel. By rotating, filters of different colors appear alternately on the light path, thereby generating light beams of different colors to ensure that each partition or group receives the correct color information. These light beams are then modulated by the digital micromirror device to form the final display interactive interface.

[0053] In this embodiment, the digital micromirror device (DMD) is based on semiconductor manufacturing technology and is an array composed of millions of tiny mirrors, each of which can independently control its tilt angle to control the direction of the reflected light. According to the control signal, the digital micromirror device (DMD) performs fast and precise tilt control on each micromirror. The tilt angle of the micromirror determines the direction of the reflected light, thereby determining whether the light beam is directed to the projection lens. By precisely controlling the tilt angle of each micromirror, the digital micromirror device (DMD) can reflect the light beam to different areas or groups, each area or group corresponding to a group of micromirrors on the digital micromirror device (DMD). Specifically, each micromirror on the digital micromirror device (DMD) can be independently controlled, and according to the control signal, the control circuit board of the digital micromirror device (DMD) will independently control the tilt angle of each micromirror. For the area or group that needs to be projected, the corresponding micromirror will be tilted to a suitable angle so that the light reflected by it can be projected onto the dining table 1. For the area or group that does not need to be projected, the corresponding micromirror will be tilted to another angle so that the light reflected by it is not projected onto the dining table 1 or onto other areas of the dining table 1.

[0054] In this embodiment, the digital micromirror device (DMD) is a key component for realizing the group projection of the interactive interface onto the dining table 1. By controlling the micromirror array on the digital micromirror device (DMD), the interactive interface can be projected onto different areas according to the group, so that multiple people can order food at the same time. At the same time, since the digital micromirror device (DMD) has the characteristics of high resolution and fast response, it can achieve high brightness, clear and smooth projection effect, and enhance the customer's ordering experience.

[0055] In this embodiment, the lens focuses and amplifies the light beam reflected by the digital micromirror device (DMD). The function of the lens is to amplify the tiny DMD pixel image and project it onto the corresponding lens.

[0056] In this embodiment, the lens projects the light beam focused and magnified by the lens onto the dining table 1 to form the final displayed interactive interface and project an image with corresponding brightness and clarity. The lens and the number of the lens are multiple.

[0057] In this embodiment, the projection device 2 further includes a heat dissipation module, which is respectively connected to the control module 21 and the optical engine module 22. When the temperature of the optical engine module 22 reaches a preset temperature value, a feedback signal is sent to the control module 21, and the control module 21 controls the heat dissipation module to dissipate heat from the optical engine module 22 according to the feedback signal, so as to ensure the stability and image quality of the projection device 2.

[0058] In this embodiment, the size of the projection device 2 is 200 mm x 150 mm x 50 mm. The size of the projection device 2 can be customized according to different usage scenarios.

[0059] In this embodiment, the projection device 2 further includes an interface module, which is connected to the control module 21. The interface module allows an external device (such as a computer, a video player, etc.) to connect to the projection device 2 and transmit data, receives an interactive screen sent by an external device, and transmits it to the control module 21.

[0060] In this embodiment, the interface module includes different types of interfaces, including but not limited to: HDMI interface (High Definition Multimedia Interface), USB interface, network interface, AV interface (composite video interface), S-Video interface (four-pin video interface), audio interface, etc.

[0061] In this embodiment, the heat dissipation module includes a fan and a motor connected to the fan. The control module 21 drives the fan to rotate through the motor to dissipate heat from the projection device 2.

[0062] In this embodiment, the gesture touch interaction module 23 includes a touch sensing sensor and an image processor connected to the touch sensing sensor. The touch sensing sensor is used to capture the customer's gestures and movements. The touch sensing sensor includes but is not limited to: an infrared sensor, a capacitive sensor, an optical camera, etc. Among them, the infrared sensor detects the customer's approach and position change by emitting and receiving infrared rays. The capacitive sensor detects touch actions by measuring changes in capacitance. The optical camera recognizes gestures and actions by capturing and analyzing images. The image processor processes and analyzes the data from the touch sensing sensor to recognize and understand the customer's gestures and movements, and converts them into electronic signals, and transmits them to the background server 3 through the control module 21.

[0063] In this embodiment, the ordering projection system further includes a kitchen touch screen, which is in communication with the backend server 3. The backend server 3 generates an order by analyzing the received electronic signal, and sends the order to the kitchen touch screen. After the chef finishes cooking, the chef touch screen feeds back the cooking completion information to the backend server 3.

[0064] In this embodiment, the ordering projection system further includes a hanging bracket, and the projection device 2 is installed directly above the dining table 1 through the hanging bracket. A mounting interface is provided on the back of the projection device 2, one end of the hanging bracket is fixed to the mounting interface, and the other end is fixed to the ceiling of the restaurant. After installing the projection device 2, turn on the projection device 2 to debug its functions. The projection device 2 can be installed during the early stage of restaurant decoration or during the later stage of restaurant operation. The only requirement is that the dining tables 1 of the restaurant are preferably of uniform size, so that its functions can be realized with only one set of software.

[0065] The meal ordering projection system of the utility model includes a dining table 1, a projection device 2 and a backend server 3. The control module 21 in the projection device 2 processes the customized interactive interface, generates a series of control signals, and sends them to the optical engine module 22.

The gesture touch interaction module 23 can capture the customer's gestures and movements, and convert the captured gestures and movements into electronic signals, which are transmitted to the backend server 3 through the control module 21. The backend server 3 generates order information by analyzing the received electronic signal, so that customers can operate and select directly on the dining table 1 without using mobile phones or other devices. As long as the customer sits down at the dining table, the ordering mode can be entered, and it supports multiple people to operate at the same time, avoiding the customer's dining experience being affected by problems such as insufficient mobile phone power or poor signal. Self-service ordering can be achieved without the customer providing personal information, protecting the security and privacy of the customer's personal data, saving the customer's time, improving the restaurant's service efficiency, creating an immersive dining experience, allowing customers to be more involved and enjoy the dining process, and enhancing the restaurant's image and competitiveness.
