Description

WEARABLE DEVICE FOR PROJECTING HOLOGRAMS BASED ON DIFFERENT BIOMARKERS OR ACTIVITIESFIELD OF INVENTION

[0001] The present invention generally relates to the field of smart wearable devices. More specifically, the present invention is related to a smart wearable device capable of projecting holograms based on different biomarkers and activities of user.BACKGROUND OF THE INVENTION

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

[0003] In recent years, wearable technology has gained significant traction in health monitoring, fitness tracking, and biometric analysis. Devices such as smartwatches, fitness bands, and smart rings have been widely adopted to measure and track vital physiological parameters, including heart rate, oxygen levels, stress levels, calorie expenditure, step count, and overall activity levels. The smart wearable devices utilize advanced sensors, accelerometers, and gyroscopes to continuously monitor a user’ s health status and provide realtime feedback. The data acquired from the smart wearable devices is typically displayed on an integrated screen or transmitted to a paired smartphone or computing device via wireless communication protocols such as Bluetooth Low Energy (BLE), Wi-Fi, or Radio Frequency (RF).

[0004] However, most existing smart wearable devices suffer from limited screen space, power constraints, and restricted visualization capabilities, making real-time health tracking cumbersome and less intuitive. Smartwatches, which provide some level of real-time feedback, often have small screen displays that restrict the amount of information that can be presented at a given time. Moreover, many compact wearables, such as smart rings, lack built-in display screens altogether, thereby forcing the users to rely on external user devices, such assmartphones or tablets, to access their health data. Such dependency on external devices introduces a delayed user interaction as it requires manual retrieval and navigation through an application to analyze vital signs and biometric trends. Such approach is impractical for the users engaged in dynamic physical activities such as running, cycling, swimming, or high- intensity workouts, where immediate access to biometric data is crucial.

[0005] Additionally, conventional User Interface (UI) in existing wearable technology rely on 2D digital displays that demand constant manual engagement, making it difficult for the users to monitor their biometric data at a glance. Such limitation becomes particularly evident in scenarios where the users need to remain focused on their surroundings, such as when driving, cycling, or operating heavy machinery. The lack of an intuitive, non-intrusive, and immersive visualization method hinders the overall effectiveness of real-time health tracking, often leading to a delayed response in addressing critical health conditions such as stress surges, dehydration, or irregular heart rate fluctuations.

[0006] Furthermore, traditional fitness tracking applications and the smart wearable devices fail to offer a seamless method for visually representing multiple biometric parameters simultaneously. While some applications allow the users to customize how their biometric data is displayed, they often rely on flat digital graphs, numerical displays, or notifications, which do not provide an engaging or dynamic way to analyze real-time biomarker trends. Additionally, these applications require the users to switch between different screens or applications to review specific health metrics, leading to an inefficient and fragmented user experience.

[0007] Thus, there remains a need of a smart wearable device for tracking, logging, displaying, and analyzing trends of various health and metabolic parameters in form of the hologram to help the users track their biomarkers and vitals in real-time.OBJECTS OF THE INVENTION

[0008] A general objective of the invention is to provide a smart wearable device capable of recording biomarkers of a user.

[0010] Yet another object of the present invention is to a smart wearable device capable of customization of the holograms based on the user preferences.

The association between the one or more user inputs and the one or more pre-defined templates of the hologram may be pre-configured or defined by the user. Further the association between the one or more predefined templates f the hologram and the one or more biomarkers of the user is also configured by user.

[0056] The middle layer 104 positioned between the outer layer 102 and the inner layer 106 may be a flexible Printed Circuit Board (PCB).

The processing unit may store values of the one or more biomarkers of the user in the memory. Further, the processing unit may regulate the projection of the hologram based on the one more user input via the touch sensor 110. The processing unit may be configured to receive one or more user input via the touch sensor and identify at least one biomarker of the user associated with the one or more user input and activate the hologram projection unit to project the hologram of the one or more biomarkers in one or more pre-defined templates.

[0060] Fig. 2 illustrates an example of user 202 communicating with the smart wearable device 100 via a user device 204, in accordance with an embodiment of the present invention. In one embodiment, the smart wearable device 100 is in the form of a ring worn on the finger of the user 202 and is configured to establish wireless communication with the user device 204. The wireless communication may be facilitated by the wireless module present within the smart wearable device 100 using protocols such as Bluetooth, Wi-Fi, or Near Field Communication (NFC) to ensure seamless data exchange between the smart wearable device 100 and the user device 204. The smart wearable device 100 may comprises a plurality of sensors that capture one or more biomarkers of the user 202 and transmit the captured sensor data to the user device 204 for processing, analysis, and visualization. The user device 204 may be configured with a dedicated application that allows the user 202 to interact with the smart wearable device 100 through an intuitive User Interface (UI). The application provides options for pre-defining hologram templates based on user preferences, where the user 202 may set different hologram templates for different biomarkers of the user 202 for tracking, notification alerts, and visualization settings. The application may further provide options to the user 202 to pre-define gestures of the one or more user input and associate the gestures ofthe one or more user inputs with specific biomarkers to be projected using predefined hologram templates. For example, the gestures of the pre-defined user inputs may include at least one of a single tap, a double tap, or a long press.

[0061] Once the one or more predefined hologram templates and the one or more predefined user inputs are received from the user device, the hologram projection unit of the smart wearable device 100 projects a predefined hologram template based on the one or more predefined user input associated with one or more biomarkers of the user 202. Additionally, the hologram projection unit within the outer layer of the smart wearable device 100 may project real-time biometric readings in a user-defined format, ensuring immediate access to critical health metrics without requiring the user 202 to check the user device 204 frequently.

[0062] Further the one or more biomarkers associated with the user 208 may be synchronized with the user device 204 at scheduled intervals, allowing the user 202 to access historical health records, perform trend analysis, and generate detailed health reports via the application interface. The user device 204 may further integrate with third-party health platforms, enabling remote health monitoring and sharing of health data with medical professionals for comprehensive analysis.

[0063] Fig. 3 illustrates a block diagram 300 of the smart wearable device 100 capable of projecting hologram, in accordance with an embodiment of the present invention. The block diagram 300 includes a smart wearable device 100, a user 202 and a user device 204. The smart wearable device 100 may be communicatively connected to the user device 204 to communicate user instruction and biomarkers data of the user. The connection between the smart wearable device 100 and the user device 204 is established by Bluetooth (BLE) modules 302, 304. In another embodiment, the connection may also be established by a Wi-Fi module or radio frequency. In another embodiment, the user device 204 may be selected from at least one of a smartphone, a tablet, or a personal computer (PC).

[0064] Further, the smart wearable device 100 may include, the BLE module 302, a plurality of sensors 306 (Hereinafter, for ease of explanation, the plurality of sensors 306 isreferred as sensors 306), a memory 308, a processing unit 310 and a hologram projection unit 312. The plurality of sensors 306 may include Spo2 sensor, heartbeat measurement sensor, Photoplethysmogram (PPG) sensor, temperature sensor, motion sensor, Electrocardiogram (ECG) sensor, barometer, accelerometer, gyroscope etc. which may gather biomarkers data of the user 202 such as heartbeat, stress level, oxygen level, workout intensity, temperature, calories burnt, step count etc. The plurality of sensors 306 provide real-time biomarker data to the smart wearable device 100 so as to analyze the user’s biomarkers data as fast and efficiently as possible. Further, the biomarkers data of the user 202 may be stored in the memory 308 of the smart wearable device 100. The memory 308 may further store one or more predefined hologram templates configured by the user and one or more predefined user input associated with one or more biomarker data biomarker. The memory 308 may be a Random-access memory (RAM) or a Read-only memory (ROM). Further, the memory 308 may store a set of computer readable instructions to perform various steps such as, projecting hologram based on the biomarker data and activities, transmitting biomarkers data of the user 202 to the user device 204, etc. The hologram projection unit 312 projects the hologram templates onto a tangible surface such as a hand, tabletop, or any nearby wall surface to ensure visibility and user readability,

[0065] Further, the smart wearable device 100 may transmit the user’s one or more biomarkers data gathered by the plurality of sensors 306 to the user device 204. The user device 204 may receive the one or more biomarkers data of the user 202 in real-time or a fixed time interval. Further, the user device 204 may comprise of an application 314, the BEE module 304 and a UI 316. It should be noted that the user device 204 receives the user’s biomarkers data from the smart wearable device 100 over a Bluetooth connection provided by the BLE module 304.

[0066] Upon receiving the one or more biomarker data of the user 202, the application 314 of the user device 204 may determine a predefined template for the one or more biomarkers to display the biomarker data of the user 202 via the hologram projection unit 312. The application 314 may also render the biomarkers data to the user 202 via the UI 316 in real-time. The application 314 may be a software installed on the user device 204 which is connected to the smart wearable device 100 via the BLE module 302. The application 314 may gather the one or more biomarkers data of the user 202 and then fills the one or more pre-defined template to display the biomarker data to the user 202. The application 314 transmits the one or more pre-defined template to the smart wearable device 100. Further, the processing unit 310 of the smart wearable device 100 may implement a micro-hologram technology to enable vivid, high- resolution 3D imaging in the user's environment. The processing unit 310 projects the data along with the pre-defined template on the hologram projection unit 312 to create a hologram in the user’s environment. Further, the user 202 may also view the real-time biomarker data on the UI 316 of the user device 204 to manually track the biomarkers data.

[0067] The application 314 may include a plurality of predefined templates based on the user preferences such as, a yellow color projection for heart rate, red color projection for oxygen levels, blue color projection for blood pressure level, etc. The application 314 may also include pre-defined templates to display a combination of biomarker data in a single hologram such as, a pink color projection for heart rate and oxygen level, a brown color projection for heart rate and blood pressure level, etc. The user preference may correspond to a choice of at least one biomarker data the user 202 wants to project as a hologram. The user 202 may provide user preference to the user device 204 in real-time via the application 314. In another embodiment, upon determining the one more predefined template based on the user preference, the application 314 may transmit the corresponding pre-defined template to the smart wearable device 100. Further, the processing unit 310 of the smart wearable device 100 may fill the one or more pre-defined template with the user preferred biomarker data in order to project the predefined template as a hologram.

[0068] In an embodiment, the user 202 may customize the properties of the holograms such as, dimension, illumination, color, brightness, etc. via the application 314. The user 202 may access the application 314 to customize the pre-defined templates and the corresponding properties of the hologram via the user device 204. The user 202 may also customize the holograms based on the various biomarker levels such as, change in stress level, heart rate falls outside a user-selected range, modifying color in response to the current step count or upon achieving a step goal, displaying different colors for various workout zones, changing color when temperature falls outside a selected range, etc. Further, the smart wearable device 100 manages the data sharing and the logic for changing of color and projection of the hologram.

[0069] In an embodiment, the user 202 may change the projected hologram based on the one or more predefined user input provided using the touch sensor 110. The one or more predefined user input may be provided by touching or holding onto the touch sensor 110 for a predefined time period. Further, the memory 308 may store instruction corresponding to thegestures of the one or more predefined user input of the user 202 received via the touch sensor 110. In an exemplary embodiment, if the user taps the touch sensor 110 once the hologram will change to the next template, or if the user taps the touch sensor 110 twice, the hologram will change to the previous hologram template, etc. The user 202 may also customize the gestures corresponding to the touch sensor 110 through the user device 204. In simpler words, the smart wearable device 100 may display the plurality of biomarker data either in a single hologram template, or the user 202 may transition between the different holograms through the touch sensor 110.

[0070] Figs. 4a, 4b, 4c, and 4d cumulatively illustrate various implementation scenarios of the smart wearable device capable of projecting hologram, in accordance with an embodiment of the present invention. As illustrated in Fig. 4a, in one implementation the smart wearable device 100 projects a hologram template showing current heart rate of the user 202. The hologram template displays a digital numeric readout at the center indicating the real-time heart rate in beats per minute (BPM), accompanied by a color-coded ring that changes based on the intensity zone such as green for normal, yellow for elevated, and red for high. In another implementation the smart wearable device 100 projects a hologram template representing a circadian phase visualization, helping the user 202 understand their biological rhythm. The hologram presents a segmented circular template illustrating key circadian zones such as the circadian dead zone, phase advance, and phase delay enabling the user 202 to align sleep, exercise, or light exposure patterns for optimal health outcomes. In another implementation the smart wearable device 100 displays a guided breathing template combined with the current heart rate zone. The hologram shows animated expanding and contracting circles that indicate “breathe in” and “breathe out” intervals. Simultaneously, a heart rate gauge appears alongside, showing whether the user is in the warm-up, fat-burn, cardio, or peak zone allowing the user 202 to synchronize breathing with physiological intensity levels for relaxation or aerobic optimization.

[0071] As illustrated in Fig. 4b, in one implementation the smart wearable device 100 projects a hologram template representing summary of daily activity metrics. The hologram displays the total number of steps taken, active kilocalories burned, and associated time stamps in a compact dashboard layout. The step count is prominently shown at the in bold numerals and active calories burned are highlighted along with start and end times of physical activity, allowing the user 202 to review performance at a glance. In another implementation the smartwearable device 100 projects a hologram template representing user’s recovery rate. The hologram features a horizontal bar graph or dial indicating percentage-based recovery (e.g., 71% recovered), derived from metrics such as heart rate variability and rest quality. Color- coded bands from red to green help the user 202 instantly gauge their physiological readiness for high-intensity activity. In another implementation the smart wearable device 100 projects a hologram template representing sleep duration and sleep cycle breakdown. The hologram projects a timeline with visually distinct segments representing light sleep, deep sleep, and REM phases. Each segment is labeled with its duration, and the overall sleep time is prominently noted. This visualization enables the user 202 to understand how well they slept and identify disruptions in sleep quality, offering insights into recovery and long-term wellness.

[0072] As illustrated in Fig. 4c, in one implementation the smart wearable device 100 projects a hologram template representing whether the user 202 is currently in a relaxed or stressed state, accompanied by specific numerical values that quantify stress levels. This enables the user 202 to visually assess their stress status in real time, facilitating prompt relaxation techniques or wellness decisions. In another implementation the smart wearable device 100 projects a hologram template representing traditional strength training. This includes key performance metrics such as number of sets, repetitions, rest periods, or load values, allowing user 202 to follow a guided workout routine without referring to an external device. This hands-free display enhances focus and continuity during training sessions. In another implementation the smart wearable device 100 projects a hologram template representing cardio age projection. The hologram not only shows the user’s estimated cardiovascular fitness level in numerical form but also contrasts it against their chronological age. This intuitive visualization helps the user 202 track long-term heart health and understand the impact of their lifestyle choices.

[0073] As illustrated in Fig. 4d, in one implementation the smart wearable device 100 projects a hologram template representing Heart Rate Variability (HRV) and Resting Heart Rate (RHR) The first part of the hologram displays the user’s HRV 7-day baseline, offering a visual trend of their HRV values over the past week, allowing the user 202 to track fluctuations and overall heart rate variability. This helps the user 202 assess their autonomic nervous system health and recovery. The second part of the template presents the user’s Resting Heart Rate (RHR), showing their average heart rate during rest, which is a critical indicator of cardiovascular fitness and general health. In another implementation the smart wearable device100 projects a hologram template representing user's temperature deviation. The hologram visually indicates variations in the user’s skin or body temperature relative to their established baseline, helping to identify anomalies that may suggest fever, stress, hormonal changes, or environmental influences. The deviation is displayed in a numeric format, complemented by a color-coded arc or gradient such as blue for lower-than-normal, green for within normal range, and red for elevated temperatures.

[0074] Fig. 5 illustrates a flowchart depicting a method 500 for projecting hologram of one or more biomarkers of the user by the smart wearable device 100, in accordance with an embodiment of the present invention. In this regard, each block may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of the order noted in the drawings. For example, two blocks shown in succession in Fig. 5 may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. Any process descriptions or blocks in flow charts should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included within the scope of the example embodiments in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved. In addition, the process descriptions or blocks in flow charts should be understood as representing decisions made by a hardware structure such as a state machine.

[0075] At step 502, the one or more biomarkers of the user 202 are measured by a plurality of sensors 306 integrated within the smart wearable device 100 The term biomarkers as used herein refers to any measurable physiological or bio -contextual indicators of the user's state, including but not limited to: heart rate, body temperature, skin hydration, electrodermal activity (EDA), blood oxygen saturation (SpO2), respiratory rate, and motion metrics such as step count and intensity of physical activity. The plurality of sensors 306 may include various physiological sensors (e.g., PPG sensors, temperature sensors, galvanic skin response sensors) and motion-related sensors (e.g., 3-axis accelerometers, gyroscopes). These sensors 306 may operate in real-time or scheduled intervals, and are capable of adaptive sampling based on user context or environmental conditions. For instance, the PPG sensor may continuously monitorheart rate, while the temperature sensor samples periodically unless a threshold anomaly is detected. The measured biomarker data is transmitted to the processing unit 310 where it is buffered and optionally pre-processed. The processing unit 310 may store values of the one or more biomarkers of the user in the memory 308.

[0076] At step 504, at least one user input is received from the plurality of predefined user inputs via the touch sensor 110 disposed on the surface of the smart wearable device 100. The touch sensor 110 may be a capacitive or piezoelectric input surface configured to recognize a variety of tactile gestures such as a single tap, double tap, long press, circular swipe, or directional slide. Each unique gesture is pre-associated with a specific user intent or command and is stored in the memory 308. For example, a double tap may indicate the user's intent to view heart rate data, while a long press might correspond to hydration status or skin temperature. The touch sensor 110 detects the input gesture, digitizes it, and transmits it as an input signal to the processing unit 310. The availability of multiple predefined inputs ensures the user has a customizable and intuitive interface for interacting with the device in a minimal, unobtrusive manner.

[0077] At step 506, the processing unit 310 identifies at least one biomarker that corresponds to the received user input. This is achieved through logic routines stored in the memory 308 that associate each gesture or the predefined user input with a particular biomarker of the user 202. Upon receiving the input, the processing unit 310 queries the mapping table and identifies the biomarker to be visualized. For instance, if the input is a double tap, and the mapping associates this input with heart rate, the processing unit 310 retrieves the corresponding real-time heart rate value from the memory 308. The processing unit 310 may also perform optional processing operations such as data normalization, averaging, anomaly detection, or comparison with historical baseline values to determine the most accurate or relevant biomarker state. Additionally, the smart wearable device 100 may accommodate user- defined mappings through a connected user device 204 (e.g., smartphone), which allows customization of input-biomarker associations, thus enhancing the flexibility of the device.

[0078] At step 508, the hologram projection unit 312 embedded within the smart wearable device 100 is activated to project a hologram representing the identified biomarker data. The processing unit 310 generates a control signal for the hologram projection unit 310 based on the identified biomarker and the corresponding hologram template. The control signal includes parameters such as shape, color, motion dynamics, and brightness of the holographic visual toensure that the projection is intuitive and informative. For instance, a pulsing red ring may indicate elevated heart rate, while a blue static ring may represent normal hydration. The hologram projection unit 312 may comprise microelectromechanical holographic elements, diffractive optical elements (DOEs), or embedded light field projectors capable of generating dynamic 3D light structures onto a physical surface such as a hand or wall or flat object near the user 202, ensuring optimal visibility and interaction. The hologram projection unit 312 renders the biomarker- specific holographic projection directly perceivable by the user 202 without the need for any external viewing device. The projected hologram may persist for a limited duration or be deactivated based on secondary inputs, timeouts, or changes in sensor readings.

[0079] The present invention provides a smart wearable device capable of projecting holograms, offering a seamless, real-time, and hands-free visualization of biometric data without relying on conventional screen-based interfaces. The integration of multiple sensors enables precise health monitoring by capturing biomarker data such as heart rate, oxygen levels, stress levels, and workout intensity. The invention leverages wireless communication technologies, including Bluetooth Low Energy (BLE), Wi-Fi, or radio frequency, ensuring efficient data transmission between the smart wearable device and a user device. Furthermore, the incorporation of predefined and customizable hologram templates enhances user experience by allowing personalized data visualization based on user preferences. The touch sensor-based gesture control mechanism further improves accessibility, enabling effortless switching between hologram projections without requiring manual intervention on the user device. Additionally, the ability to project holograms on various surfaces provides an intuitive and non-intrusive means for tracking real-time biometric data, making the invention highly versatile for fitness, healthcare, and daily activity monitoring applications.
