BACKGROUND OF THE INVENTION

[0002] Modern commercial environments increasingly focus on creating interactive and immersive experiences that enhance customer satisfaction and engagement. In such settings, delivering personalized communication, real-time information, and sensory-rich interactions plays a crucial role in influencing customer behavior and decision-making. The approach is particularly significant in retail and food service environments, where timely guidance, attractive presentation, and responsive interaction improve overall service quality. In real-life scenarios such as restaurants, malls, and entertainment spaces, enabling the businesses to connect more effectively with visitors, improve experience flow, and encourages informed choices by engaging and adaptive presentation of information.

[0003] The conventional approaches rely on static displays, manual communication, and non-adaptive presentation of information, which limits the level of customer interaction and engagement. Information delivery remains uniform for all visitors, regardless of individual preferences or timing, reducing personalization and responsiveness. Customer feedback and behavior interpretation are largely dependent on manual observation, which lead to delayed responses and reduced efficiency in service adaptation. In real-time commercial environments, the methods struggle to maintain immersive experiences, resulting in lower engagement quality, reduced influence on decision-making, and limited ability to dynamically adjust to changing customer expectations.

[0023] The system disclosed herein comprises of a first display panel 101 that is mounted on a restaurant wall. The first display panel 101 is adapted to present animated visuals, advertisements, promotional content, and highlighted food items in an engaging format. The first display panel 101 includes a high-resolution display substrate formed using liquid crystal, which serves as the primary output surface for visual presentation. A protective transparent outer layer is provided to ensure optical clarity and mechanical durability. Beneath the display substrate, a display driver circuit is operatively arranged to control individual pixel activation through row and column addressing, thereby enabling precise rendering of animated visuals, advertisements, promotional content, and highlighted food items. The display panel 101 is ergonomically positioned to maximize visibility and is constructed with high-resolution capabilities to ensure clarity and appeal.

[0024] A real-time clock module is integrated into the first display panel 101 to continuously track time through communication with a microcontroller embedded within the first display panel 101. The real-time clock module operates using an internal oscillator that generates a stable clock signal, regulated by a crystal element to ensure high precision and minimal drift. The generated oscillation pulses are processed through internal divider circuits to derive standard time units including seconds, minutes, and hours, which are sequentially updated and stored in dedicated registers.

[0025] The stored time data is periodically accessed by the microcontroller for synchronization and control purposes. A backup power source is provided to maintain uninterrupted timekeeping during main power loss, thereby preserving temporal continuity. The microcontroller utilizes the retrieved temporal data to dynamically control displayed content, including modifying visual themes, brightness levels, and color schemes based on predefined time-of-day intervals to ensure contextual relevance.

[0026] A second interactive display panel 115 is mounted at the restaurant entrance to allow the customers to input commands, requests, and present available deals and offers. in an interactive format. The second interactive display panel 115 comprises a high-resolution display screen overlaid with a capacitive touch interface that detects user interactions through variations in an electrostatic field. Upon user input through touch, a touch controller converts the detected signals into digital coordinates, which are transmitted to the microcontroller for interpretation. The microcontroller processes the input commands and retrieves the corresponding data including menu options, requests, and offers, from a linked database. A display driver renders the updated graphical content in real time, enabling responsive and seamless user interaction.

[0027] A user interface is linked with the system to enable authorized restaurant owners and managers to securely update the operational parameters, including daily offers, special dishes, food quality metrics, quantity information, and promotional advertisements. The user interface ensures that all updates are reflected instantaneously across both connected display panels 101, 115 for maintaining consistency and real-time accuracy of information presented to customers. The authorized restaurant owners and managers interact with the user interface through a touch screen, keyboard, or other input methods available on a computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet. The wireless communication between the microcontroller of the system and the computing unit is achieved through a communication module integrated with the microcontroller.

[0028] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the system is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. The Wi-Fi module connects to a network via an access point, converting digital data into radio signals. The Wi-Fi module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0029] An imaging unit 102 is installed on the first display panel 101 that captures real-time images of incoming customers within its field of view. The imaging unit 102 operates through an integrated optical and electronic architecture, wherein an optical lens assembly receives and focuses incident light from the target region onto a photosensitive sensor array composed of multiple pixel elements. Each pixel converts the incoming light into proportional electrical charges based on the intensity of illumination. The generated analog signals are sequentially read out through row and column addressing circuits, amplified to enhance signal strength, and processed through filtering circuits to reduce noise and improve image clarity. The conditioned signals are then converted into digital image data by an analog-to-digital converter and transmitted to the microcontroller for processing and projection purposes.

[0030] After the microcontroller processes the captured image data, the processed data is subsequently transmitted to an integrated holographic projector 103 in a synchronized manner. The holographic projector 103 operates through a light modulation and projection operation to generate three-dimensional visual representations. Upon receiving the processed data, the projector 103 converts it into projection-compatible signals and directs them to a spatial light modulation unit, wherein phase and amplitude characteristics of a coherent light source are modulated in accordance with the image data. The modulated light is then guided through a projection assembly including optical elements such as beam splitters and diffraction gratings to reconstruct the image wavefront. The reconstructed wavefront forms a visually engaging holographic projection in space, which is continuously updated to enable real-time dynamic visualization that attracts customer attention and enhances interactivity.

[0031] An artificial intelligence (AI) module is integrated with the microcontroller to receive and analyze the captured imaging data by the imaging unit 102 using facial expression recognition (FER) protocols such as Facial Action Coding System (FACS) for determining customer emotions, preferences, and behavioral patterns, and enabling the microcontroller to tailor recommendations and displayed content accordingly. The FER protocol operates by processing the received facial image data through a sequence of computational stages, including face detection, feature extraction, and expression classification.

[0032] Initially, the facial region is isolated from the captured image and normalized for scale and orientation. Key facial landmarks such as eyes, eyebrows, nose, and mouth are identified, and corresponding feature vectors are generated based on geometric relationships and texture patterns. The feature vectors are then processed using a trained classification model that maps the extracted features to predefined emotional states. The resulting output is interpreted by the AI module to determine user sentiment, which is further utilized for adaptive content optimization and personalized recommendation generation.

[0033] An aroma storage cartridge 113 is installed on the first display panel 101 and is equipped with an atomizing nozzle 114 that disperses controlled quantities of food-based scents into the surrounding environment and creates a multisensory experience for the customers by stimulating olfactory senses. The aroma storage cartridge 113 stores liquid food-based aromatic compounds in a sealed, contamination-free environment while maintaining the stability and integrity of the stored formulations until activation.

[0034] Upon receiving an activation signal from the microcontroller, a controlled release operation initiates the transfer of the aroma liquid from the aroma storage cartridge 113 to the atomizing nozzle 114. The atomizing nozzle 114 operates by converting the incoming liquid aroma into a fine mist through a pressure-based atomization process, wherein the liquid is forced through a micro-orifice and disintegrated into ultra-fine droplets to form a uniform aerosolized spray.

[0035] Internally, the atomizing nozzle 114 comprises a pressurization chamber and precision-engineered outlet channel, where controlled pressure buildup is generated by a micro-pumping operation regulated by the microcontroller. The pressure differential forces the liquid through the micro-orifice at high velocity, causing shear-induced breakup of the liquid stream into fine particulate droplets. The nozzle 114 geometry further assists in optimizing droplet size distribution for uniform dispersion. The generated mist is dispersed into the surrounding environment in a regulated manner, with dispersion rate and timing controlled by the microcontroller to ensure desired sensory impact and to prevent over-saturation of aroma within the environment.

[0036] A plurality of food storage compartments 104 is mounted on a linear slider 105 installed on a platform 106. Each food storage compartment 104 is fabricated from, but not limited to, food-grade stainless steel material to ensure hygiene, durability, and resistance to corrosion. The platform 106 is operatively coupled to a linear actuator 107 that enables controlled linear movement of the compartments 104 for accessibility and positioning. The linear actuator 107 operates by converting electrical energy into controlled linear displacement through an electromechanical drive operation.

[0037] Upon receiving control signals from the microcontroller, an internal electric motor generates rotational motion, which is transmitted to a lead screw assembly. The rotational motion is converted into linear movement through threaded engagement between the screw and a carriage assembly. The linear movement drives the platform 106 along a predefined axis with precise positioning. Internal guide rails and bearing assemblies ensure smooth and stable movement with reduced friction, while continuous positional regulation by the microcontroller maintains operational accuracy during extension and retraction cycles.

[0038] After the platform 106 is positioned accurately by the linear actuator 107, the linear slider 105 on the platform 106 moves along a guided track. The linear slider 105 comprises of a sliding carriage assembly engaged with precision-engineered guide rails that ensure stable and low-friction motion. Upon receiving actuation input from the microcontroller, a driving operation such as a lead screw imparts linear force to the carriage, causing it to move along the rail axis. The guide structure maintains alignment and prevents lateral deviation during motion. Position control is regulated through controlled drive input, enabling accurate stopping at designated locations during operational cycles to enable controlled lateral displacement of the food storage compartments 104 for facilitating precise positioning and accessibility of different food items for sampling and tasting by the customers.

[0039] Each food storage compartment 104 is designed to store different food items intended for sampling and tasting by customers, and is further equipped with a Peltier thermoelectric unit 108 integrated with a temperature sensor 109 to maintain optimal storage conditions for different food types.

[0040] The temperature sensor 109 operates by continuously monitoring the thermal conditions within the food storage compartment 104 using a temperature-sensitive element such as a resistance temperature detector, in which the electrical resistance changes in proportion to variations in temperature. The resulting change is then converted into an analog electrical signal, which is conditioned through amplification and filtering to enhance measurement accuracy and stability. The conditioned signal is then converted into a digital form via an analog-to-digital converter and transmitted to the microcontroller for processing. The microcontroller evaluates the received temperature data against predefined thresholds to ensure maintenance of optimal storage conditions for the stored food items.

[0041] The Peltier thermoelectric unit 108 then adjusts the heating or cooling output based on feedback from the temperature sensor 109 by modulating the applied current to maintain the desired temperature level. The Peltier thermoelectric unit 108 comprises of semiconductor junctions arranged between two ceramic plates to form a thermoelectric operation. When a direct current is supplied, charge carriers within the semiconductor material transfer heat energy from one side of the unit to the other, and creates a temperature differential across the surfaces. One surface absorbs heat to produce a cooling effect, while the opposite surface dissipates heat to the external environment. The direction and magnitude of the applied current regulate the thermal mode and intensity, ensuring precise temperature control for stored food items.

[0042] Additionally, an electrochemical sensor 110 is provided within each food storage compartment 104 to monitor chemical changes indicative of food spoilage. The electrochemical sensor 110 operates by detecting chemical variations in stored food items through electrochemical reactions occurring at a sensing electrode assembly comprising a working electrode, a reference electrode, and an electrolyte medium that facilitates ion transfer. When spoilage indicators interact with the sensing surface, a redox reaction is initiated, generating a potential difference proportional to the concentration of the detected analyte. The generated electrical output is conditioned through amplification and filtering circuits to improve signal stability and accuracy. The conditioned signal is then converted into digital form via an analog-to-digital converter and transmitted to the microcontroller. The microcontroller analyzes the received input against predefined thresholds and generates alert notifications to the user interface upon detection of deviations from safe storage conditions, ensuring food safety and quality.

[0043] Upon detection of chemical spoilage, the alert notification is generated with the help of a speaker 117 that converts electrical audio signals into audible sound waves through an electromechanical transduction process. The speaker 117 comprises a diaphragm, voice coil, permanent magnet, and suspension operation arranged within a compact housing. The microcontroller supplies a varying electrical audio signal to the voice coil, resulting in the generation of an alternating magnetic field. The magnetic field interacts with the static magnetic field of the permanent magnet, producing a controlled mechanical force that drives the movement of the voice coil. The attached diaphragm vibrates in response to this motion, displacing surrounding air particles to generate corresponding pressure waves. The sound waves are emitted into the surrounding environment as an audible alert notification indicating spoilage detection.

[0044] The platform 106 further comprises an articulated arm 111 coupled to a spoon-tipped end effector 112. The articulated arm 111 operates as a multi-axis robotic handling operation to retrieve selected food items from designated food storage compartments 104 based on user input received through the second display panel 115. The articulated arm 111 comprises a plurality of interconnected rigid segments joined through motor-driven rotational joints, enabling movement across multiple degrees of freedom. Upon receiving control signals from the microcontroller, servo motors positioned at respective joints generate coordinated rotational movement to accurately position the articulated arm 111 above the selected food storage compartment 104. The movement sequence is governed through programmed kinematic operations, wherein joint angles, rotational speed, and positional alignment are continuously regulated to ensure precise movement and stable operation during food retrieval.

[0045] The food is then picked up and transferred to an auxiliary serving plate for customer sampling with the help of the spoon tipped end effector 112 that is mounted at the terminal end of the articulated arm 111 through a coupling interface to ensure stable positioning during operation. The spoon tipped end effector 112 comprises a spoon-shaped receptacle to receive, retain, and transfer a predefined quantity of food material. During operation, the articulated arm 111 aligns the spoon-tipped end effector 112 with a selected food storage compartment 104 using controlled translational and angular movements. The spoon receptacle is then inserted into the compartment 104 to collect the food item while maintaining balanced orientation and controlled motion to prevent spillage during retrieval and transfer. Subsequently, the articulated arm 111 repositions the spoon-tipped end effector 112 above the auxiliary serving plate, where a controlled tilting action enables accurate deposition of the retrieved food item onto the serving plate for customer sampling.

[0046] A camera 116 is mounted on the platform 106 to monitor the food sampling and serving operations in real time. The camera 116 provides continuous feedback to the microcontroller, enabling dynamic adjustments in positioning, alignment, and motion of the articulated arm 111, spoon tipped end effector 112 and the platform 106 to ensure smooth and error-free operation. The camera 116 operates in the similar manner as the imaging unit 102 aforementioned.

[0047] The second display panel 115 is integrated with the speaker 117 that delivers audio instructions, alerts, and promotional messages to the user. Furthermore, the second display panel 115 is integrated with a microphone 118 that receives voice commands from the users and enables voice-based interaction and enhancing accessibility. The microphone 118 comprises a diaphragm, transduction element, housing structure, and signal processing circuitry that converts the incoming acoustic signals into corresponding electrical signals.

[0048] During operation, the sound waves generated by user speech create pressure variations that vibrate the diaphragm in proportion to the received voice input. The diaphragm movement actuates the internal transduction operation to generate electrical audio signals representative of the detected voice commands. The generated signals are subsequently processed through internal amplification, filtering, and noise reduction circuitry to improve signal clarity, speech recognition accuracy, and background noise suppression. The processed voice signals are then transmitted to the microcontroller for interpretation and execution of corresponding user commands.

[0049] The second display panel 115 at the end takes the restaurant feedback from the user and updates the linked database accordingly. The AI module further processes the returning customer profile data obtained from the linked database by correlating prior order history and tasting satisfaction scores computed by the AI module for optimizing the recommendations and enhancing customer engagement to improve decision-making efficiency and increase order conversion rates.

[0050] The present invention works best in the following manner, where customer engagement is initiated upon entry into the restaurant environment and interaction begins through the first display panel 101 to present animated visuals, advertisements, promotional content, and food item highlights, with content dynamically adjusted by the real-time clock module and processed through the microcontroller. Incoming customers are captured by the imaging unit 102, and the microcontroller processes the captured data to enable projection via the integrated holographic projector 103 for immersive visual engagement. The AI module analyzes imaging data using FER protocols to determine behavioral patterns and generate optimized recommendations. Customers then interact through the second interactive display panel 115 to select food items, which are retrieved from the plurality of food storage compartments 104 on the linear slider 105 of the platform 106 using the articulated arm 111 coupled with the spoon-tipped end effector 112 and deposited onto an auxiliary serving plate. Aroma storage cartridge 113 with atomizing nozzle 114 enhances sensory experience, while the camera 116 monitors operations for alignment control. The speaker 117 and microphone 118 enable audio interaction, and the communication module ensures wireless connectivity with the computing unit and user interface for real-time monitoring and control.
