Description

Technical Field

[0001] This invention relates to the field of smart wearable devices, specifically a dimmable dice wearable device. Background Technology

[0002] In this era of unprecedented technological explosion, while technology brings immense convenience and possibilities, it also spawns a series of complex new challenges. In this technologically accelerated, competition-driven society, teenagers bear immense pressure from their studies and future aspirations. Simultaneously, their primary social and entertainment spaces are rapidly shifting to a rich yet potentially isolating, distorted, and disruptive online world. The high pressure of the real world and the allure of the virtual world are jointly squeezing out the physical and psychological space essential for the healthy development of teenagers—a space filled with unstructured social interaction, free exploration, and emotional exchange. Against this backdrop, we have invented a dimmable dice wearable device, distinct from traditional electronic accessories.

[0003] Existing light-emitting electronic jewelry still has the following shortcomings in practical applications: First, most existing light-emitting electronic accessories use fixed constant-on control schemes or preset simple flashing logic. The color, brightness, and flashing frequency of the light source in these products are usually fixed during the production stage. Wearers cannot make targeted adjustments according to their real-time needs and emotions in different social situations or when facing different lighting environments, resulting in a weak interactive experience and failing to meet users' psychological expectations for personalized expression.

[0004] Secondly, existing luminous electronic accessories are often designed to operate independently due to their compact size, lacking the ability to coordinate and sense with the external environment or similar devices. When multiple wearers are in close social spaces, the accessories cannot generate feedback based on changes in spatial distance, nor can they achieve synchronized lighting effects. This "information silo" phenomenon, caused by the lack of short-range data exchange mechanisms, limits the application potential of wearable products in social interaction scenarios.

[0005] Finally, most existing electronic jewelry only has a single lighting and decorative function, failing to establish a direct mapping relationship between the wearer's subjective emotional state and the objective dynamic effects of light. The wearer's emotional fluctuations are difficult to convey digitally and visually to the outside world through the medium of jewelry, making the jewelry more of a tool than an emotionally interactive item.

[0006] In conclusion, developing an intelligent interactive die that can sense social distance in real time, achieve multi-terminal light and color fusion, and digitally map the wearer's emotional fluctuations is a pressing technical challenge in the current field of electronic jewelry.

[0007] This invention combines LED display, audio playback, and wireless communication technologies to provide real-time feedback based on the user's emotional changes, offering a rich interactive experience. Through simple button operations, users can switch emotions, broadcast emotions, or receive emotional information from other devices, creating an emotion-driven environment. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a dimmable dice wearable device, which solves the problems mentioned in the background section.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a dimmable dice wearable device, comprising a dice shell, wherein a main control circuit board is disposed within the cavity of the dice shell, and the main control circuit board integrates a central processing unit, an LED dot matrix module, a near-field sensing unit, a wireless communication unit, an audio conversion unit, and a power storage unit; the central processing unit is connected to the LED dot matrix module, the near-field sensing unit, the wireless communication unit, the audio conversion unit, and the power storage unit through electrical circuits.

[0010] Through the above technical solution, by highly integrating a central processing unit, LED dot matrix module, near-field sensing unit, wireless communication unit, audio conversion unit, and power storage unit within the housing space of the dice shell, and utilizing the central processing unit to perform coordinated logic control and power distribution for each functional module, multimodal deep interactive functions such as digital lighting adjustment, near-field spatial perception, cross-terminal wireless data synchronization, and audiovisual synchronous feedback are realized within a compact physical structure of the jewelry. This endows the electronic jewelry with intelligent wearable characteristics that enable emotional expression and social interaction, significantly improving the technical integration and human-computer interaction depth of the decorative product.

[0011] Preferably, the near-field sensing unit includes a Hall sensor or an infrared proximity sensor for real-time monitoring of external magnetic field fluctuation signals or infrared reflection signals within a 3-centimeter radius around the die shell; when the external magnetic field fluctuation signal or infrared reflection signal reaches a preset threshold, the central processing unit generates an interactive start command.

[0012] The above technical solution enables sensitive capture of microscopic changes in the spatial environment, establishes a specific social interaction sensitivity standard of three centimeters, and provides a precise logical trigger benchmark for the system to switch from standby state to active interaction state.

[0013] Preferably, the central processing unit responds to the interactive start command and controls the LED dot matrix module to execute a centripetal shrinkage animation; the centripetal shrinkage animation is manifested as the light-emitting pixels on each surface of the die shell changing their brightness layer by layer from the outer edge to the center area according to a preset time interval, presenting a circular shrinking light and shadow visual effect.

[0014] The above technical solutions give the jewelry a dynamic and layered visual feedback effect, and use the spatial displacement of light and shadow from the outside to the inside to simulate the visual image of energy aggregation, which significantly enhances the sense of ritual and fun of the product during close interaction.

[0015] Preferably, the wireless communication unit is used to send the local color code to the external device during the activation of the interactive start command, and simultaneously receive the corresponding color code fed back by the external device; the central processing unit performs a fusion calculation on the local color code and the corresponding color code according to a weighted average algorithm, and drives the LED dot matrix module to display the fused new color.

[0016] The above technical solution enables the establishment of a digital information link between the two devices. By using a weighted average algorithm, the abstract social contact is transformed into a concrete new color generation logic, reflecting the social connection attributes of mutual influence and color interweaving between wearers.

[0017] Preferably, the central processing unit has preset negative emotion mode numerical ranges and positive emotion mode numerical ranges to adjust the output parameters of the LED dot matrix module.

[0018] The above technical solution constructs a structured data processing logic for the device. By setting specific numerical ranges, abstract human emotional fluctuations can be accurately classified and quantified by the central processing unit, laying the parameter foundation for subsequent display adjustments.

[0019] Preferably, when the central processing unit is in the negative emotion mode value range, the driving current of the LED dot matrix module is reduced to weaken the light color saturation; when the central processing unit is in the positive emotion mode value range, the driving current of the LED dot matrix module is increased to improve the light color saturation.

[0020] The above technical solution realizes a direct mapping between the physical characteristics of light and human emotional and psychological states. By adjusting the current duty cycle to regulate visual perception, users can intuitively convey their real-time mood to the outside world in a non-verbal way.

[0021] Preferably, the surface of the die shell is provided with an interactive button, which is connected to the data pin of the central processing unit.

[0022] The above technical solutions provide users with a direct and reliable physical operation entry point, ensuring the immediacy and accuracy of command transmission during human-computer interaction, and facilitating wearers to actively switch functions according to their emotions or social environment.

[0023] Preferably, the audio conversion unit is connected to a built-in miniature speaker; while the central processing unit drives the LED dot matrix module to perform color changes, it sends a synchronization pulse signal to the audio conversion unit, so that the built-in miniature speaker outputs a prompt tone consistent with the color change frequency.

[0024] Through the above technical solution, the synchronous output of light effects and audio signals is achieved. The interactive feedback is deepened through the synesthetic effect, creating a more three-dimensional and holographic sensory interactive experience for the wearer.

[0025] Preferably, the die housing is further provided with a gravity sensor; the gravity sensor detects the flip angle of the die housing and converts the flip angle into position data and sends it to the central processing unit, which adjusts the display direction of the LED dot matrix module according to the position data.

[0026] The above technical solution solves the problem of display deflection caused by human movement during wear. Through the posture adaptive compensation algorithm, it ensures that the displayed image always maintains a positive view relative to the observer, thus improving the stability and consistency of the visual display.

[0027] Preferably, the die shell is made of a light-guiding particle mixed resin material, and the inner wall of the die shell is provided with a light-diffusing layer; the light emitted by the LED dot matrix module is diffused through the light-diffusing layer and then passes through the die shell to achieve a uniform distribution of the overall brightness of the die.

[0028] By utilizing the secondary diffusion effect of composite materials and optical physical layers, the visual blind spots and glare caused by LED point light sources are effectively eliminated, resulting in a soft, transparent and omnidirectionally uniform visual texture after the light penetrates the shell.

[0029] This invention provides a wearable dice device with adjustable light. It has the following advantages: 1. This invention achieves dynamic and digital adjustment of the decorative effect of wearable devices by integrating an LED display module with a light-guiding composite material shell. Wearers can switch the color, brightness, and saturation of the light in real time according to different social occasions or personal emotions, effectively solving the problem of the monotonous and unchangeable appearance of traditional solid jewelry, and significantly improving the personalized attributes of wearable products.

[0030] 2. This invention establishes a multi-device linkage mechanism through the built-in near-field sensing unit and wireless communication module, realizing physical spatial perception and emotional data information sharing between adjacent devices. When multiple devices approach each other, the light effect fusion and contraction animation triggered can output the wearer's psychological state in a non-verbal form, giving the jewelry a new social interaction vitality and greatly enhancing the fun and emotional resonance of interaction between people.

[0031] 3. This invention achieves highly integrated multi-dimensional feedback functions such as light control, mood switching, gravity sensing, and audio synchronization within the limited internal space of the dice shell by intelligently integrating interactive buttons, gravity sensing, and audio conversion unit through the central processing unit. Users can complete complex mode changes through simple physical operations. While maintaining the portability and compact structure of the jewelry, it significantly expands the functional boundaries and human-computer interaction depth of electronic wearable devices.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 - Appendix Figure 3 The dimmable dice wearable device disclosed in this embodiment aims to provide wearable devices with spatial awareness and emotional expression capabilities through the deep integration of electronic technology.

[0035] Part 1: System Architecture and Physical Construction The core structure of this dimmable dice wearable device includes a dice shell. The shell has a hexahedral structure and is made from a modified resin material mixed with nano-sized light-guiding particles via injection molding. An additional translucent diffuse reflection coating is sprayed onto the inner wall of the shell to form a soft-light layer. This dual-layer optical structure serves two purposes: when the internal light source emits light, the nano-sized light-guiding particles guide the light to the shell surface, while the soft-light layer eliminates visual blind spots caused by point light sources, resulting in a uniform and full fluorescent texture that emanates from the inside out.

[0036] The main control circuit board is installed in the central cavity of the die's casing. This circuit board integrates a central processing unit, a power storage unit, a wireless communication unit, a near-field sensing unit, an LED dot matrix module, and a gravity sensor. The power storage unit obtains external energy through magnetic charging contacts located at the bottom of the die's casing and provides a stable power supply to all the aforementioned electronic components.

[0037] Part Two: Near-Field Triggering and Dynamic Display Logic The near-field sensing unit is configured to monitor the electromagnetic field environment around the die shell in real time. When the near-field sensing unit detects a sensing signal within a preset intensity range (corresponding to a spatial distance of less than three centimeters), the sensing signal is transmitted to the central processing unit and triggers an interactive interrupt request.

[0038] In response to the interrupt request, the central processing unit (CPU) drives the LED dot matrix module to execute a centripetal contraction animation. During this animation, the brightness of each pixel in the LED dot matrix module follows a specific timing logic: the outermost pixels light up first and then quickly decrease in brightness, followed by the innermost pixels which trigger sequentially with a delay. This on / off logic visually creates a dynamic effect where light and shadow converge from the edge of the die shell towards the geometric center. Simultaneously, the CPU retrieves a pre-stored audio stream from the audio conversion unit and synchronously plays a frequency-controlled pulse prompt tone through a miniature receiver. The sound pressure level of this prompt tone is strongly correlated with the frequency of the centripetal contraction animation, achieving an immersive audiovisual feedback experience.

[0039] Part Three: Wireless Communication and Color Fusion Algorithms Upon near-field triggering, the wireless communication unit automatically activates broadcast and scan modes. The local device encapsulates the current color code (stored in RGB numerical form) stored in the central processing unit register into a data packet and broadcasts it to the outside world. Simultaneously, the local device receives the color code broadcast from the external device.

[0040] After acquiring the two sets of color codes, the central processing unit (CPU) invokes its built-in color fusion algorithm. This algorithm sets weighting coefficients based on the activity level of the local device, linearly weighting and summing the local and remote RGB values ​​to calculate the target fused color value. For example, if the local device displays blue and the remote device displays red, the algorithm adjusts the color channel ratios to output a mysterious purple. Subsequently, the CPU uses pulse width modulation (PWM) to adjust the duty cycle of the driving waveform, driving the LED dot matrix module to switch to the target fused color value, thereby representing the social connection trajectory between the two wearers through changes in visual color.

[0041] Part Four: Emotion Regulation and State Customization Mechanisms The die's casing has an embedded interactive button on its side. Users can send a mode-switching command to the central processing unit (CPU) by closing the button. The CPU has preset positive and negative emotion zones.

[0042] When the central processing unit determines that the current state is a negative emotion mode, the logic controller automatically reduces the peak driving current of the LED dot matrix module and limits the color range, keeping the display light effect in a low-saturation, cool-toned range to reflect the wearer's depressed or calm emotional state. When the user switches back to a positive emotion mode via the interactive button, the central processing unit increases the duty cycle of the driving current, increases the luminous flux, and switches to a high-saturation, warm-toned color matrix, giving the dice wearable device a vibrant and bright visual effect.

[0043] Part 5: Spatial Attitude Perception and Image Correction To ensure visual stability during wear, the gravity sensor continuously acquires the acceleration vector data of the dice shell in a three-dimensional coordinate system. The central processing unit dynamically adjusts the pixel display matrix of the LED dot matrix module by calculating the angle between the aforementioned vector data and the reference plane in real time. Regardless of how the dice shell is rotated during wear, the central processing unit can ensure that the displayed text, patterns, or ripple effects remain vertically centered in the user's viewpoint through a rotation coordinate transformation algorithm, thereby eliminating visual displacement deviation caused by object movement.

[0044] In summary, this embodiment, through the logical coupling of precise components, not only solves the problem of monotonous jewelry appearance, but also realizes multiple functions such as social interaction, emotion mapping, and spatial form adaptation through digital means, greatly expanding the application boundaries of smart wearable devices.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
