Description:DYNAMIC RGB LED RING FOR SMARTWATCH BEZELS: A MULTIFUNCTIONAL INTERFACE FOR ENHANCED USABILITY AND INTERACTION ACROSS DIVERSE SCENARIOS
FIELD 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 with dynamic bezel to provide visual feedback.
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] Smart wearable devices, particularly smartwatches, have revolutionized the way users interact with technology by integrating advanced functionalities such as health tracking, fitness monitoring, communication, and navigation. Such devices primarily rely on screen-based feedback mechanisms to convey information, requiring the users to actively engage with display of the device for updates. However, such approach presents several limitations, including high power consumption, reduced battery life, and usability constraints in scenarios where screen interaction is impractical. Additionally, frequent screen activation can be disruptive, especially in professional or social settings, leading to the need for alternative feedback mechanisms that do not rely solely on visual screen-based interaction.
[0004] Existing smart wearable devices technologies have attempted to address these challenges by incorporating haptic feedback, ambient light sensors, gesture-based controls, and low-power display modes. The haptic feedback, such as vibrations, provides a discreet way to notify the users, but it lacks the ability to convey detailed or context-specific information. The gesture-based controls, while eliminating the need for direct physical interaction, often require exaggerated movements or predefined gestures that can be unreliable in dynamic environments. Some smart wearable devices employ always-on displays or low-power display modes to improve usability without excessive battery drain, however, such solutions still require the display to remain active, which inherently consumes power. Furthermore, the ambient light sensors are commonly used to adjust the display brightness but do not contribute to providing non-intrusive, glanceable feedback.
[0005] One notable limitation of current smart wearable devices design is underutilization of bezel, which remains largely unused apart from aesthetic or mechanical functions, such as housing rotating dials or touch-sensitive controls. While some smart wearable devices manufacturers have experimented with LED indicators, such implementations are often limited to basic status lights, single-color notifications, or rudimentary alert signals that do not provide comprehensive real-time feedback. For example, certain devices use single-color LEDs to indicate charging status or Bluetooth connectivity, but such implementations do not offer dynamic, multi-color, or context-aware functionality that could enhance the user experience in a broader range of applications.
[0006] Another significant issue with existing solutions is their inability to provide an effective, hands-free method of delivering contextual information. In scenarios such as workouts, driving, or outdoor activities, the users may find it inconvenient or unsafe to engage with a screen or perform touch-based interactions. Audio notifications, another commonly used alternative, may not always be practical in noisy environments or quiet settings where sound-based alerts can be disruptive. Additionally, the users with hearing impairments may find audio-based notifications ineffective, highlighting the need for a more inclusive approach to non-intrusive feedback.
[0007] Thus, there is a need for a smart wearable device with a dynamic bezel to overcome the above-mentioned challenges.
OBJECTS OF THE INVENTION
[0008] An object of the present invention is to provide a smart wearable device with a dynamic bezel to deliver non-intrusive, context-aware visual feedback without requiring user interaction.
[0009] Another object of the present invention is to enable display-independent operation, allowing the bezel to convey essential notifications, fitness metrics, navigation guidance, and alerts even when the display is off.
[0010] Yet another object of the present invention is to provide a multi-colour, adaptive visual feedback, where the bezel dynamically changes colours, brightness levels, and lighting patterns based on real-time sensor inputs and user-defined preferences.
[0011] Yet another object of the present invention is to enhance hands-free usability by eliminating the need for touch, gesture, or voice-based interactions, making it suitable for various scenarios.
[0012] Yet another object of the present invention is to provide a customizable and user-configurable feedback system, allowing the users to define lighting preferences, color-coded indications, and alert patterns for different types of scenarios.
[0013] Yet another object of the present invention is to provide real-time emergency alerts for critical conditions to the user.

[0050] The present invention relates to a smart wearable device with a dynamic bezel. The smart wearable device incorporates a light-emitting unit integrated around the bezel, configured to provide visual feedback to the user independent of user input. The smart wearable device comprises a plurality of sensors to detect operational parameters, including physiological, motion, environmental, and device interaction parameters. A processing unit is communicatively coupled to the sensors and the light-emitting unit, analyzing the detected operational parameters and real time notifications to determine visual feedback parameters such as color variations, brightness levels, and lighting patterns. Based on the visual feedback parameters the processing unit send control signals to operate the bezel by providing necessary visual feedback to the user.

[0051] Fig. 1 illustrates a top view of a smart wearable device 102 worn by a user 104, in accordance with an embodiment of the present invention. The smart wearable device 102 may comprises a light-emitting unit integrated around bezel 106 of the smart wearable device 102 to offer multi colored indications and is worn by the user 104. In one implementation the smart wearable device 102 may be a smartwatch. The shape of the smart wearable device 102 is not limited to circular as the shape may also be elliptical, square, rectangular, or any other geometric configuration based on the design requirements. The bezel 106 surrounding display 108 of the smart wearable device 102 incorporates the light-emitting unit, which comprises a plurality of light-emitting diodes (LEDs) configured to provide adaptive visual feedback to the user 104 without requiring any user input. The light-emitting unit functions independently of the display 108, ensuring that notifications, status updates, and alerts may also be conveyed to the user 104 without requiring activation of the display 108.
[0052] The smart wearable device 102 may further comprises a plurality of sensors. The plurality of sensor may be configured to detect one or more operational parameters. The smart wearable device 102 may further comprises a processing unit communicatively coupled to the plurality of sensors and the light-emitting unit. The processing unit may be configured to receive the one or more operational parameters, analyze the one or more parameters to determine one or more visual feedback parameters and transmit one or more control signals based on the one or more visual feedback parameters to regulate operation of the light emitting unit.
[0053] The light-emitting unit is configured to operate in response to different real-time conditions, where each condition corresponds to a unique visual feedback parameter. The processing unit is further configured to process real-time notifications to determine the one or more visual feedback parameters and accordingly regulate the visual feedback of the light-emitting unit. The visual feedback includes incremental and decremental illumination of the light emitting unit in a directionally progressive manner along the bezel 106 of the smart wearable device 102. The processing unit may also enable user-configurable preferences, allowing the user 104 to select specific colours and lighting patterns for and real-time notifications. The light-emitting unit may be customized to provide predefined colour variations based on user settings, ensuring a personalized interaction experience. The smart wearable device 102 enables advanced user-specific customization of the light-emitting unit. The smart wearable device 102 may be coupled to a user device that supports an application through which the user 104 may configure fully personalized LED behaviour, including selection of specific colours for various types of alerts, adjustment of brightness intensity to match environmental conditions or user preference, and definition of timing characteristics such as pulse rate, duration, and fade-in/fade-out profiles. Furthermore, the user 104 may define specific triggers such as biometric thresholds, time-based events, or motion detection that activate unique lighting patterns. This highly customizable light emitting unit framework provides a rich degree of personalization, allowing the user 104 to tailor the device’s visual output to suit individual goals, contexts, or accessibility requirements. Such configurability significantly enhances the flexibility and usability of the smart wearable device 102, and contributes to a user-centred interaction model that adapts dynamically to changing needs and environments.
[0054] Additionally, the bezel 106 of the smart wearable device 102 has been deliberately engineered with a design that aims to reduce cognitive load during interaction. The smart wearable device 102 translates operational states into intuitive visual cues using the light emitting unit indicators. For example, instead of displaying "5:30 min/km" as a running pace on the screen, which demands real-time reading and mental processing by the user 102, the smart wearable device 102 may present this pace range through a specific color or light progression on the bezel 106. Such abstraction allows the user 104 to understand status or alerts at a glance, without the need for active interpretation of digits or phrases, thereby enabling low-effort, rapid information processing during high-motion or time-constrained situations. Such thoughtful reduction in cognitive demand makes the device especially advantageous in physically active or attention-sensitive contexts.
[0055] Furthermore, the smart wearable device 102 operates in an energy-efficient manner, where the light-emitting unit functions independently of the display 108 to reduce power consumption and extend battery life. The processing unit optimizes the power efficiency by regulating the intensity and duration of illumination based on real-time usage conditions. The smart wearable device 102 enhances hands-free usability, making it particularly effective in scenarios where direct interaction with the screen is impractical. Additionally, the light-emitting unit may be configured to provide emergency alerts, where specific color-coded indicators or flashing patterns represent critical conditions of the user. By integrating a dynamic, multi-functional light-emitting unit into the bezel 106, the present invention provides an intuitive, non-intrusive, and efficient feedback mechanism.

[0057] The smart wearable device 102 may further comprises rotary dials 206 and a plurality of sensors 208 (Hereinafter, for ease of explanation the plurality of sensors 208 also referred as sensors 208). The rotary dials 206 are coupled to the sensors 208, which transmits signals via an I2C (Inter-Integrated Circuit) communication bus to the processing unit 202. The rotary dials 206 may provide rotational input, which can be mapped to various functionalities such as navigating system menus, adjusting brightness levels, scrolling through notifications, and modifying settings in a tactile manner. Further the sensors 208 may be configured to detect one or more operational parameters. The sensors 208 may include, but not limited to a motion sensor, an accelerometer, a gyroscope, a biometric sensor, a SpO2 sensor, a temperature sensor, an electrodermal activity sensor, an Electrocardiogram (ECG) sensor, a Photoplethysmography (PPG) sensor, an ambient light sensor, a proximity sensor, a barometer, an altimeter, a magnetometer, a Global Positioning System (GPS) sensor, and a capacitive touch sensor. Further the one or more operational parameters may include but not limited to one of physiological parameters, motion parameters, environmental parameters and device interaction parameters.
[0058] The physiological parameters may include metrics such as heart rate, blood oxygen levels (SpO2), Electrocardiogram (ECG) readings, skin temperature, and electrodermal activity, allowing the smart wearable device 102 to monitor the user health and provide insights into fitness and well-being. The motion parameters may include accelerometer and gyroscope data, enabling the detection of steps, gestures, rotational movements, and activity intensity, which are essential for workout tracking and navigation. The environmental parameters may include ambient light levels, temperature, barometric pressure, GPS location, and magnetic field strength, allowing the device to adapt display brightness, provide altitude data, or determine the user’s surroundings. Lastly, the device interaction parameters may include rotary dial inputs, touch gestures, button presses, and voice commands, which help the smart wearable device 102 interpret the user commands and adjust the visual feedback accordingly. By continuously analyzing the above-mentioned parameters, the smart wearable device 102 optimizes the visual feedback mechanisms, ensuring a seamless and context-aware user experience.
[0059] Further, the display 108 of the smart wearable device 102 is connected via MIPI (Mobile Industry Processor Interface) or I2C to the processing unit 202. The display 108 is an AMOLED +touch display which acts as a primary visual interface, rendering dynamic screens, interactive elements, and device notifications based on operational state of the smart wearable device 102.The smart wearable device 102 may further comprises a light emitting unit 210.The light emitting unit 210 is coupled with the processing unit 202 via GPIO/PWM (Pulse Width Modulation) signals. The light emitting unit 210 is integrated around the bezel 106 of the smart wearable device 102. The light emitting unit 210 is configured to provide the visual feedback without receiving any user input. The light emitting unit 210 comprises one or more Light Emitting Diodes (LEDs). Further, the light emitting unit 210 is configured to operate independent of the display 108 of the smart wearable device 102.
[0060] The processing unit 202 is further configured to receive the one or more operational parameters from the sensors 208. The processing unit 202 analyze the one or more operational parameters received from the sensors 208 and determine one or more visual feedback parameters to regulate operation of the light emitting unit 210. The one or more visual feedback parameters may include but not limited to colour variations (indicating different statuses or events), brightness levels (adaptive to ambient lighting or user preferences), lighting patterns (such as pulsating, flashing, or gradient transitions), duration of illumination (adjusting the one or more LEDs activation periods based on use cases) and segmented illumination (lighting up specific sections of the bezel 106 for directional or segmented feedback).The processing unit 202 transmit one or more control signals to the light emitting unit 210 based on the one the one or more visual feedback parameters to regulate operation of the light emitting unit 210. The light emitting unit 210 may comprises the one or more Light Emitting Diodes (LEDs). The one or more LEDs is configured to emit different colours based on the visual feedback parameters. The different colours of the light emitting unit 210 is selected based on preferences of the user 104.The processing unit 202 continuously regulates the behaviour of the light emitting unit 210, ensuring that the light emitting unit 210 provides meaningful and relevant visual feedback without requiring user intervention. The visual feedback includes incremental and decremental illumination of the light emitting unit 210 in a directionally progressive manner along the bezel 106 of the smart wearable device 102. The incremental and decremental illumination of the light emitting unit 210 indicates progression or completion of the one or more operational parameters.
[0061] The processing unit 202 is further configured to process real-time notifications to determine the one or more visual feedback parameters and generate the one or more control signals to regulate the operation of the light emitting unit 210. The real-time notifications may include but not limited to communication alerts, system status updates, calendar reminders, activity-based alerts, and external event notifications. The communication alerts include incoming calls, messages, and app notifications. The system status updates involve battery levels, connectivity status, or software updates. The calendar reminders may include notifications about meetings, appointments, or scheduled tasks. The activity-based alerts include notifications about tracking fitness goals, step counts, hydration reminders, or workout milestones and the external event notifications include weather updates, emergency alerts, stock market changes, or smart home interactions.
[0062] In one implementation, the smart wearable device 102 may allow user-defined customization of the light emitting unit 210 through the application executable on the user device. The user 104 may configure the light emitting unit 210 behaviour by selecting preferred colours, brightness levels, timing intervals, and activation triggers for different events or operational parameters. For instance, the user 104 may set a flashing blue pattern to indicate hydration reminders or a slow pulsing green to reflect calm breathing during meditation. Such customization options introduce a high degree of personalization and control, enabling the smart wearable device 102 to adapt to the unique use cases and preferences of each individual user 104.
[0063] The smart wearable device 102 may be designed to reduce cognitive load during user interaction. Instead of requiring the user 104 to interpret detailed numeric values or text-based prompts such as heart rate readings or exertion levels, the processing unit 202 may translate such data into intuitive LED-based visual indicators through the light emitting unit 210. For example, during a workout session, rather than displaying “145 bpm” as a heart rate reading on the display 108, the light emitting unit 210 may glow in a steady amber color to indicate that the user is within a moderate heart rate zone, and shift to red if a high exertion threshold is reached. This approach allows the user 104 to perceive important biometric states at a glance, without having to actively read and interpret numerical data, thereby reducing mental effort and improving usability during physically intensive or high-focus tasks.
[0064] The smart wearable device 102 may further comprises a haptic motor 212. The haptic motor 212 is coupled to the processing unit 202 via the GPIO/PWM signals. The haptic motor 212 is configured to provide vibrational feedback, enhancing the user experience by enabling discrete alerts, tactile confirmations, and activity-based notifications. The smart wearable device 102 may further comprises a buzzer 214. The buzzer 214 is coupled to the processing unit 202 via the GPIO/PWM signals. The buzzer 214 produces include alert sounds, alarm tones, and status notifications. The haptic motor 212 and the buzzer 214 enhance the multi-sensory feedback system by providing tactile and auditory responses.
[0065] Fig. 3a, 3b, 3c, 3d cumulatively illustrates various implementation scenarios of the smart wearable device with dynamic bezel, in accordance with an embodiment of the present invention. As illustrated in Fig. 3a, in one implementation, circadian rhythm notification is displayed using the bezel 106, which illuminates in a circular pattern to indicate progression. This allows the user 104 to track their circadian cycles without actively engaging with the display 108, ensuring minimal power consumption while providing passive notifications. In another implementation, stress rhythm score and graph are shown, where the bezel 106 adjusts illumination to reflect stress levels. The bezel 106 may change colors or brightness based on real-time data, allowing quick assessment without requiring detailed interaction with the display 108.
[0066] In yet another implementation, sleep index quality graph is presented, where the bezel 106 acts as a visual progress indicator for sleep duration. This feature enhances the user 104 health monitoring capabilities by offering at-a-glance insights without fully activating the display 108. The bezel 106 displays recovery scores with soft, calming colours, such as blue for high recovery and red for low recovery, upon waking. In one more implementation, the smart wearable device 102 assists the user 104 with navigation for cycling or driving, where the bezel 106 provides turn-by-turn directional cues. Illuminated segments indicate upcoming turns, ensuring seamless navigation without excessive screen distractions, aligning with safety considerations.
[0067] In yet another implementation, the smart wearable device 102 offers navigation support for walking, adapting the bezel 106 output based on pedestrian navigation requirements. This enhances usability by ensuring guidance is always visible, even in outdoor environments where quick glances are necessary. In another implementation, heart rate trend monitoring is visually represented, where the bezel 106 reacts to real-time fluctuations. The colour intensity or pattern changes dynamically, ensuring that user 104 receive immediate feedback on their cardiovascular status without needing to access the display 108. Rapid red flashes signal critical conditions, such as abnormal heart rate readings or detected falls, alerting the user 104 or nearby individuals to take immediate action. In yet another implementation, time display is integrated into the bezel, allowing the user 104 to check the time even when the display 108 is off. This power-efficient feature extends battery life while maintaining essential functionality. In another implementation the smart wearable device 102 remind the user 104 to hydrate, stand, or take short breaks without disrupting focus or requiring sound-based alerts through the bezel 106 by providing subtle pulsations. Further the bezel 106 also provides discrete notifications for meetings or deadlines, ensuring seamless integration into professional environments.
[0068] As illustrated in Fig 3b, in one implementation, the bezel 106 enhances workout tracking for activities such as running, cycling, and swimming. The bezel 106 dynamically illuminates in different colors to indicate various metrics, such as heart rate, pace, and elapsed time, ensuring real-time feedback without requiring users to focus on the display 108. In bright sunlight, where the display 108 is hard to read, the bezel 106 functions as the primary feedback mechanism, providing clear visual indicators for navigation, fitness progress, or notifications to the user 104. In another implementation, charging display visualization utilizes the bezel 106 to indicate battery status. A progressive lighting effect visually represents charge level, providing a quick and intuitive way to assess charging progress without activating the display 108. In yet another implementation, breathwork timer employs the bezel 106 for guided breathing exercises. A countdown is visually represented through segmented illumination, assisting the user 104 in synchronizing their breaths with the timer. The gradual dimming and brightening effect help create a calming experience, reinforcing role of the smart wearable device 102 in stress management and mindfulness training.
[0069] As illustrated in Fig 3c, in one implementation, breathwork mode utilizes a visual guidance to facilitate structured breathing exercises. The bezel 106 transitions through different phases such as inhale, hold, and exhale with corresponding color-coded animations and countdown timers. This guided sequence helps the user 104 regulate their breathing for relaxation and stress management. In another implementation, the bezel 106 illumination synchronizes with the breathwork phases, providing an external visual cue for the user even when the display 108 is off. This feature ensures a distraction-free experience while maintaining engagement during the exercise.
[0070] As illustrated in Fig 3d, in one implementation, during a general workout session, the bezel 106 illuminates in distinct colors to indicate key metrics such as elapsed time, heart rate, and activity type. Such real-time feedback allows the user 104 to monitor workout progress at a glance without requiring continuous interaction with the display 108. The bezel 106 serves as an intuitive indicator, ensuring seamless engagement even in environments where the display 108 may be less visible, such as bright outdoor conditions. In another implementation, workout bubble view slider employs the bezel 106 to facilitate navigation through different exercise modes. As the user 104 rotates or interacts with the bezel 106, the bezel illumination dynamically shifts to highlight the selected workout option. This interaction streamlines the workout selection process, ensuring a fluid transition between exercise types without excessive on- display interaction. Additionally, when an exercise is selected, the bezel 106 momentarily pulse or change colors to provide immediate confirmation, enhancing user experience and interaction efficiency.
[0071] In yet another implementation, the bezel 106 illuminates in a segmented pattern, where each completed repetition triggers a progressive lighting effect, reinforcing the user's progress in real-time. Similarly, when the timer is activated, the bezel 106 dynamically transitions its illumination to represent the countdown visually, allowing the user 104 to track time-based exercises without solely relying on the display 108. This implementation enhances workout precision by ensuring the user 104 remain informed about their exercise performance with minimal distractions. In yet another implementation, rest timer employs the bezel 106 to provide a structured cooldown experience. The bezel 106 gradually changes color and brightness to indicate the remaining rest period, creating a visual representation of the recovery phase. Such dynamic transition ensures that the user 104 can easily gauge when to resume their workout without constantly checking the display 108. By leveraging the bezel 106 for visual cues during rest intervals, the smart wearable device 102 optimizes workout efficiency while maintaining an intuitive and immersive user experience.
[0072] Fig. 4 illustrates a flowchart depicting a method 400 for providing visual feedback in a smart wearable device 102, 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. 4 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.
[0073] At step 402, the one or more operational parameters are detected via the plurality of sensors 208 embedded within the smart wearable device 102. The sensors 208 may include, but are not limited to, physiological sensors such as Photoplethysmography (PPG) sensors, electrodermal activity sensors, temperature sensors, and motion sensors such as accelerometers and gyroscopes. The sensors 208 are configured to continuously or periodically monitor parameters such as heart rate, skin temperature, hydration levels, step count, motion intensity, and other bio-physical or contextual states relevant to the user 104. The smart wearable device 102 initiates data acquisition based on predefined schedules, user-initiated triggers, or event-based conditions such as the commencement of physical activity or detection of abnormal physiological values. The sensors 208 generate raw data corresponding to the monitored conditions, which is then transmitted internally to the processing unit 202. Such detection step enables real-time and context-aware data acquisition, which forms the foundation for generating dynamic and intuitive visual feedback for the user through the smart wearable device 102.
[0074] At step 404, the one or more operational parameters detected from the plurality of sensors 208 are received and the processing unit 202 process and analyze the one or more operational parameters to determine one or more visual feedback parameters. The processing unit 202, which may include a microcontroller or embedded processor, executes logic routines stored in memory to analyze the incoming sensor data. Such analysis may involve filtering, averaging, threshold comparison, pattern recognition, or progress computation, depending on the nature of the one or more operational parameter. For example, in the case of activity tracking, the processing unit 202 may compute percentage completion of a target step count. In biometric monitoring, it may detect deviations from baseline heart rate. Based on this analysis, the processing unit 202 determines one or more visual feedback parameters, such as the number of segments to illuminate, the color or intensity of light, or temporal patterns of blinking or fading. Subsequently, the processing unit 202 generates and transmits one or more control signals to the light emitting unit 210, instructing it on how to render the visual feedback in a manner that reflects the evaluated state of the user’s operational parameters.
[0075] At step 406, operation of the light emitting unit 210 is regulated, which is integrated around the bezel 106 of the smart wearable device 102, based on the one or more control signals received from the processing unit 202. The light emitting unit 210 may comprise a plurality of discrete LEDs, OLED segments, or a continuous light strip, configured to emit light in a sequential manner. Upon receiving the control signals, the light emitting unit 210 activates in a directionally progressive manner to visually communicate the status or progression of the detected operational parameters. The term "directionally progressive manner" refers to an illumination sequence that follows the geometry of the bezel, whether circular, oval, rectangular, or polygonal thereby allowing visual indicators such as progress arcs, segment-based completion loops, or directional flows. For instance, if the device tracks hydration level, each illuminated segment may represent a percentage increment; the completion of the loop may indicate goal achievement. This mode of feedback eliminates reliance on a textual or graphical display, enabling glanceable and intuitive interaction with the smart wearable device 102. Additionally, the regulation of light emitting unit 210 may include dynamic attributes such as brightness modulation, color transitions, or rhythmic patterns to signify urgency, achievement, or alerts thereby enhancing the functional expressiveness and user engagement of the device.
[0076] In one implementation, the visual feedback parameters may also be personalized by the user 104 through the application executable on the user device, which enables configuration of color schemes, intensity levels, illumination timing, and trigger conditions, providing a highly adaptable and user-defined feedback experience. Additionally, the design of the smart wearable device 102 emphasizes reduced cognitive effort by enabling the user 104 to interpret operational data through simplified visual cues instead of text-based or numerical displays, thereby enhancing real-time usability and decision-making.
[0077] The present invention provides a smart wearable device with a dynamic bezel that offers non-intrusive, screen-independent visual feedback, reducing reliance on power-intensive display-based notifications. The multi-color adaptive bezel enables real-time, context-aware indications based on sensor inputs, enhancing usability in various scenarios such as fitness tracking, navigation, and notifications. By operating independently of the screen, the bezel optimizes power consumption, extending battery life while ensuring continuous information delivery. The invention further enhances hands-free usability, making it ideal for driving, workouts, and other situations where direct interaction is impractical. Additionally, the customizable lighting system allows the users to personalize color-coded alerts, improving intuitiveness and accessibility. The invention also enhances situational awareness by providing real-time emergency alerts for critical conditions such as abnormal heart rates or distress signals. By maximizing the use of the smartwatch bezel, the invention introduces a functional and aesthetically integrated feature that significantly improves user experience and device interaction.
