Description

Technical Field

[0001] This invention relates to the field of attention assistive devices, and in particular to an attention assistive device that integrates tactile feedback and visual cues. Background Technology

[0002] In today's fast-paced, information-overloaded society, maintaining sustained, high-quality focus has become a core competency for individuals in learning, work, and even life. However, individuals are highly susceptible to distractions from various internal and external factors when performing tasks requiring concentration. External distractions include environmental noise, visual stimuli, and notifications from smart devices; internal distractions stem from an individual's psychological state, such as anxiety, stress, fatigue, and a jumble of thoughts. These distractions collectively lead to the widespread phenomenon of inattention, severely impacting learning efficiency, work productivity, and mental health.

[0003] To combat distraction, people have explored various methods of focus training. Among them, mindfulness meditation, as a method widely validated by scientific research, is gaining increasing popularity. Through meditation, trainees learn to anchor their attention on specific bodily sensations (such as breathing or tactile sensations), thereby cultivating awareness and reducing distractions. However, for beginners, meditation is not easy to master. They generally face a core challenge in practice: even in a quiet environment, it is easy to lose focus, and thoughts tend to wander unconsciously. It is difficult to maintain stable attention on the anchor point for an extended period, leading to a tedious and frustrating training process, making it difficult to persevere, and ultimately significantly reducing the training effect.

[0004] To aid concentration training, some electronic meditation aids have emerged on the market, but most of them focus on providing feedback through audio guidance (such as playing meditation prompts or white noise) or physiological data monitoring (such as brainwaves and heart rate). However, audio guidance is relatively passive and may not be effective in bringing users back when their minds wander deeply; while physiological data monitoring devices are usually expensive, complicated to wear, and provide limited and delayed feedback, making them more suitable for outcome evaluation than process intervention.

[0005] Therefore, there is an urgent need in this field for a new type of assistive device that is not only portable and easy to use, but more importantly, can proactively, gently, and continuously and effectively provide immediate intervention when the user is distracted, constantly guiding the user's wandering attention back to bodily awareness, thereby lowering the entry barrier for concentration training such as meditation and improving training effectiveness. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a focus assist device that integrates tactile feedback and visual cues, so as to fundamentally solve the problems of the single mode and limited effect of existing focus assist tools.

[0007] According to an embodiment of the present invention, a focus assist device integrating tactile feedback and visual cues includes a housing, and a visual cues component, a main control circuit, a power supply component, a control component and a tactile feedback component housed in the housing;

[0008] The visual cue component includes at least one light-emitting element disposed on the main control circuit, and the housing is provided with a light-transmitting portion corresponding to the position of the light-emitting element;

[0009] The haptic feedback component includes a drive mechanism, a transmission mechanism connected to the drive mechanism, and a touch mechanism connected to the transmission mechanism and for contact with a user. The transmission mechanism is configured to convert the rotational motion of the drive mechanism into the circular motion of the touch mechanism in a predetermined plane, thereby generating regular haptic feedback.

[0010] The main control circuit is electrically connected to the light-emitting element, the power supply component, the control component, and the drive mechanism, and is configured to respond to user commands that the user outputs to the control component, and accordingly coordinate to control the display mode of the visual prompt component and the operating mode of the haptic feedback component, so as to assist the user in entering a state of focus.

[0011] In addition, a focus assist device integrating tactile feedback and visual cues according to the above embodiments of the present invention may also have the following additional technical features:

[0012] Furthermore, the housing includes an upper cover and a lower cover, the lower cover having a central partition that separates different chambers, and the central partition having a connecting hole that connects the various chambers;

[0013] The drive mechanism is located in the receiving cavity of the middle partition near the upper cover, and the transmission mechanism is located in the rotating cavity of the middle partition away from the upper cover and is connected to the drive shaft of the drive mechanism after passing through the connecting hole.

[0014] Furthermore, the transmission mechanism includes a slider connected to the drive mechanism and a rotating arm slidably connected to the slider. The rotating arm is provided with a groove extending along its length direction, and the slider is accommodated in the groove and can slide along the groove.

[0015] The touch mechanism includes an elastic element connected to a fixed post on the top surface of one end of the rotating arm, and a touch element detachably connected to the end of the elastic element, wherein the touch element extends out of the plane at the bottom end of the housing.

[0016] Furthermore, the bottom of the slider is provided with a rectangular groove, and an elastic spring sheet protruding outward is provided in the rectangular groove. Multiple slots that engage with the elastic spring sheet are provided at intervals along the length of the inner wall of the groove. The rotating arm is locked by the engagement of the elastic spring sheet with any of the slots, thereby determining the rotation radius of the touch element relative to the drive shaft in the drive mechanism.

[0017] Furthermore, the transmission mechanism also includes a radius adjustment mechanism mounted on the rotating arm and rotating together with the rotating arm;

[0018] The radius adjustment mechanism includes a drive motor electrically connected to the main control circuit, a lead screw that is radially arranged along the slider and connected to the output shaft of the drive motor for rotation, a support base that is arranged at both ends of the lead screw and fixedly connected to the rotating arm, a sliding nut that passes through the lead screw for axial movement, and a connecting piece that is connected to the sliding nut and the slider respectively.

[0019] Furthermore, the slider includes a main body connected to the output shaft of the first drive mechanism, and a sliding part disposed in the slide groove and perpendicularly connected to the main body;

[0020] The support base includes a base plate fixedly connected to the side wall of the rotating arm, two side plates perpendicular to both ends of the base plate and connected to both ends of the lead screw, and a guide reinforcing rod connected to the two side plates;

[0021] The sliding nut passes through the guide reinforcing rod, and the end of the sliding nut away from the lead screw is provided with a receiving groove for accommodating the connector;

[0022] The connector has a connecting block that is accommodated in the accommodating groove at one end near the sliding nut, and the connector has an accommodating hole for accommodating the main body of the slider.

[0023] Furthermore, the visual cueing component includes a plurality of warning lights arranged linearly on the control circuit and facing the upper cover, and a plurality of low beam lights arranged in an array on both sides of the warning lights;

[0024] The inner surface of the top cover is provided with a transparent rectangular frame corresponding to each of the warning lights and a lens corresponding to each of the low beam lights. The inner surface of the top cover is integrally formed with multiple honeycomb units arranged in an array in the area outside the transparent rectangular frame and the lens for softening light and directing light.

[0025] Furthermore, the inner wall of the receiving chamber is provided with reinforcing ribs for supporting the main control circuit and limiting buckles for limiting the main control circuit.

[0026] The top of the reinforcing rib includes an internal support portion facing the center of the receiving chamber, and an external positioning portion extending upward from the outer edge of the internal support portion.

[0027] The edge of the main control circuit is provided with a support groove that cooperates with the external positioning part. The bottom surface of the main control circuit located in the inner area of ​​the support groove is supported on the internal support part of the reinforcing rib. At the same time, the external positioning part of the reinforcing rib is accommodated in the support groove for limiting, and the edge of the main control circuit is held and fixed by the limiting buckle.

[0028] Furthermore, the power supply component includes a battery and a charging module electrically connected to the main control circuit, and the battery is disposed between the main control circuit and the drive mechanism;

[0029] The charging module includes a charging spring piece housed in the receiving cavity of the lower cover and electrically connected to the main control circuit, and a magnetic attracting piece disposed on the outer wall of the lower cover.

[0030] The outer wall of the lower cover is provided with a charging port for the charging spring to extend out, a fixing groove for accommodating and fixing the magnetic iron piece, and a positioning groove for positioning the external charger.

[0031] The magnetic iron sheet has a reserved hole corresponding to the charging port and a positioning hole corresponding to the positioning groove.

[0032] Furthermore, the side wall of the lower cover is provided with at least one button slot that extends through the inside and outside. The control component includes a control button that is accommodated in each of the button slots and can be pressed, and a switch circuit board that is vertically connected to the main control circuit and corresponds to the position of the control button. The switch circuit board is provided with a control switch that corresponds to the position of the control button.

[0033] The central partition is provided with multiple clamping plates for clamping and fixing each of the switch circuit boards. The lower end of each switch circuit board is clamped between two clamping plates, and the upper end is fixed and electrically connected to the main circuit.

[0034] The attention aid device integrating tactile feedback and visual cues provided in this invention achieves synchronous guidance of both tactile and visual sensory channels through the coordinated control of a tactile feedback component that generates regular circular motion and a visual cues component that provides rhythmic light effects via a main control circuit. This creates a gentle, non-invasive, and continuous focus anchor for the user, greatly improving the efficiency and depth of guiding the user into and maintaining a state of focus. Furthermore, by setting a central partition inside the housing, the internal space is divided into a receiving chamber for the main control circuit and drive mechanism and a rotating chamber for the transmission mechanism, achieving physical isolation between dynamic mechanical components and static precision electronic components, effectively avoiding the impact of mechanical vibration and electromagnetic interference on circuit stability. The transmission mechanism, composed of a slider and a rotating arm with a groove, smoothly converts the rotational motion of the drive mechanism into the circular motion of the touch mechanism within a predetermined plane, and connects the touch mechanism via an elastic element, achieving a slow and gentle tactile feedback. Finally, by also incorporating a radius adjustment mechanism (driving the extension and retraction of the rotating arm via a lead screw drive) in the transmission mechanism, the rotational motion is further adjusted. The decoupling and dynamic collaborative control of motion and radius adjustment enable the touch mechanism to depict complex, programmable two-dimensional dynamic trajectories such as spirals and pulsations. The adjustable locking of the touch mechanism's rotation radius is achieved by setting elastic springs on the slider and cooperating with multiple slots on the inner wall of the rotating arm's slide groove. A composite optical structure, consisting of a transparent rectangular frame corresponding to the warning light, a lens corresponding to the low beam, and honeycomb units distributed throughout the remaining areas, achieves precise control and softening of light, ensuring clear status information while creating a uniform, comfortable, and glare-free ambient lighting effect. A robust fixing method with multi-point support and multi-directional limiting is achieved by setting reinforcing ribs and limiting buckles on the inner wall of the receiving cavity and precisely cooperating with the support grooves on the edge of the main control circuit board, ensuring the absolute stability of the core circuit under complex conditions such as impact and vibration. A magnetic charging solution, including charging springs, magnetic iron pieces, positioning holes, and positioning slots, provides a convenient, safe, and blind-operable charging experience, solving the problems of limited modes and effectiveness in existing attention assistive tools.

[0051] Example 1

[0052] Please see Figures 1-10 The image shows a focus assist device integrating tactile feedback and visual cues according to the first embodiment of the present invention. For ease of explanation, only the parts related to the embodiment of the present invention are shown. The focus assist device integrating tactile feedback and visual cues provided in the embodiment of the present invention includes a housing 10, and a visual cues component 20, a main control circuit 30, a power supply component 40, a control component 50 and a tactile feedback component 60 housed in the housing 10.

[0053] The visual cue component 20 includes at least one light-emitting element disposed on the main control circuit 30, and the housing 10 is provided with a light-transmitting portion corresponding to the position of the light-emitting element;

[0054] The haptic feedback component 60 includes a drive mechanism 61, a transmission mechanism 62 connected to the drive mechanism 61, and a touch mechanism 63 connected to the transmission mechanism 62 and for contact with the user. The transmission mechanism 62 is configured to convert the rotational motion of the drive mechanism 61 into the circular motion of the touch mechanism 63 in a predetermined plane, thereby generating regular haptic feedback.

[0055] The main control circuit 30 is electrically connected to the light-emitting element, the power supply component 40, the control component 50 and the drive mechanism 61 respectively, and is configured to respond to user commands to control the output of the control component 50, and correspondingly coordinate the control of the display mode of the visual prompt component 20 and the operation mode of the haptic feedback component 60 to help the user enter a state of focus.

[0056] In one embodiment of the present invention, the focus-enhancing device aims to help users shield themselves from external distractions and enter and maintain a state of focus by providing a gentle, regular, and non-invasive sensory input. It is suitable for scenarios requiring high concentration, such as learning, working, and meditation. The core of this focus-enhancing device is a compact housing 10 that can be held in the hand or placed on a table. The housing 10 integrates all the functional modules of the focus-enhancing device, including a visual cue component 20, a main control circuit 30, a power supply component 40, a control component 50, and a haptic feedback component 60. The main control circuit 30 is typically a printed circuit board (PCB) with an integrated microcontroller (MCU), responsible for receiving user commands, managing power, and coordinating the control of the visual cue component 20 and the haptic feedback component 60. The power supply component 40 provides energy to the focus-enhancing device, typically a rechargeable lithium battery 41, which is charged via a charging module 42. The control component 50 is the interface for user interaction with the focus-enhancing device, such as a physical button or touch-sensitive area, through which the user turns the device on / off, switches modes, etc. The visual cue component 20 provides visual guidance through changes in light, such as soft lighting effects that simulate breathing frequency, helping users adjust their breathing and relax. The visual cue component 20 consists of at least one light-emitting element (such as an LED) soldered onto the main control circuit 30. To allow light to pass through, the housing 10 has corresponding light-transmitting sections. The tactile feedback component 60 generates a slow, regular tactile sensation. It drives a transmission mechanism 62 via a drive mechanism 61 (such as a miniature DC geared motor), cleverly converting the motor's rotational motion into circular motion of the touch mechanism 63 within a predetermined plane at the bottom of the attention assist device. During this slow, regular circular motion, when the user's hand or wrist touches the touch mechanism 63, a continuous and predictable tactile feedback is generated, which helps anchor the user's attention.

[0057] Specifically, when a user issues a user command via control component 50 (e.g., setting a "30-minute focus mode"), the main control circuit 30 simultaneously activates the visual cue component 20 and the haptic feedback component 60. For example, the main control circuit 30 can control the light-emitting element to present a slow "breathing light" effect (a cycle of brightness from dark to bright and back to dark), while simultaneously controlling the drive mechanism 61 to rotate at a set low speed (e.g., 10-30 revolutions per minute), driving the touch mechanism 63 to perform circular motion. When the 30-minute timer ends, the main control circuit 30 controls the light-emitting element to turn on or off, visually informing the user that the focus time has ended. At this time, the visual rhythm and the tactile rhythm can be synchronized, forming a multi-sensory synergistic guidance, greatly enhancing the effect of assisting the user in entering a state of focus.

[0058] Therefore, in this embodiment of the invention, a main control circuit 30 integrating a microcontroller is designed. This main control circuit 30 is electrically connected to the light-emitting element, the power supply component 40, the control component 50, and the drive mechanism 61 (i.e., its motor drive circuit). The firmware program written and burned into the microcontroller can parse the user's input commands (such as turning on / off or switching modes) via the control button 51, and synchronously output PWM signals according to preset program logic to control the light-emitting element's on / off state, brightness, and flashing mode (visual cues), and control the motor drive circuit of the drive mechanism 61 to adjust the drive mechanism 61's speed and start / stop (haptic feedback). When the user needs to use the attention assist device, they hold it in their palm, select the desired mode, and start it via the control button 51. After receiving the command, the main control circuit 30 drives the haptic feedback component 60 to start working, and the touch element 632 performs continuous circular motion in the user's palm. When a user's thoughts wander, this rhythmic tactile stimulation from the body provides a continuous anchor point for focus, gently and effectively drawing the user's attention back to the physical sensations, thus interrupting distractions and helping them quickly return to a focused state. Visual cues (such as a breathing light) help users regulate their circadian rhythms, and users can also obtain device status or timing information at any time through the visual cue component 20. Therefore, the synergistic effect of these two feedback methods makes it more effective than any single feedback method in guiding users into and maintaining a focused state.

[0059] In one embodiment of the present invention, to achieve a compact, stable, and easily assembled internal structure, the housing 10 is designed to be formed by fastening or screwing together an upper cover 11 and a lower cover 12, typically made of injection-molded engineering plastics such as ABS or PC. Specifically, the housing 10 includes an upper cover 11 and a lower cover 12. The lower cover 12 has a central partition 121 that separates different chambers, and the central partition 121 has connecting holes 122 that connect the various chambers. A drive mechanism 61 is located in the receiving chamber of the central partition 121 near the upper cover 11, and a transmission mechanism 62 is located in the rotating chamber of the central partition 121 away from the upper cover 11 and is connected to the drive shaft of the drive mechanism 61 passing through the connecting hole 122. Specifically, the lower cover 12 has a central partition 121 inside, which divides the interior of the lower cover 12 into upper and lower chambers. The chamber closest to the top cover 11 is a housing chamber for static electronic components, such as the main control circuit 30, power supply assembly 40, and drive mechanism 61. The chamber furthest from the top cover 11 is a rotating chamber, providing unobstructed dedicated space for the rotational movement of the transmission mechanism 62. A connecting hole 122 is provided in the central partition 121, through which the drive shaft of the drive mechanism 61 (i.e., the motor) passes to connect with the transmission mechanism 62 below. The advantages of this separation design are: firstly, it achieves separation of static and dynamic components, effectively isolating the rotating moving parts from the static precision electronic components, protecting the main control circuit 30 and other precision electronic components, avoiding interference with the moving parts or wear due to long-term movement, thus improving the long-term operational reliability of the equipment; secondly, the partitioned layout makes the internal space planning clear, clarifies the assembly process, facilitates automated production and subsequent maintenance, and makes production more efficient; finally, it effectively isolates the noise and vibration that may be generated by the drive mechanism 61, making it less likely to be directly transmitted to the main control circuit 30, reducing the interference of mechanical vibration on the circuit.

[0060] Furthermore, in one embodiment of the present invention, in order to ensure that the main control circuit 30 remains stable when the device is subjected to impact or vibration, a fixing structure is carefully designed on the inner wall of the receiving chamber. Specifically, the inner wall of the receiving chamber is provided with a reinforcing rib 123 for supporting the main control circuit 30 and a limiting buckle 124 for limiting the main control circuit 30; the top of the reinforcing rib 123 includes an internal support portion facing the center of the receiving chamber and an external positioning portion extending upward from the outer edge of the internal support portion; the edge of the main control circuit 30 is provided with a support groove 31 that cooperates with the external positioning portion, the bottom surface of the main control circuit 30 located in the area inside the support groove 31 is supported on the internal support portion of the reinforcing rib 123, and the external positioning portion of the reinforcing rib 123 is accommodated in the support groove 31 for limiting, and the edge of the main control circuit 30 is held and fixed by the limiting buckle 124. During assembly, the bottom surface of the main control circuit 30 first rests stably on the internal support parts of all the reinforcing ribs 123, while the external positioning parts of the reinforcing ribs 123 are precisely embedded into the support grooves 31 of the main control circuit 30, thus achieving vertical support and initial horizontal positioning. Finally, the lateral limiting buckles 124 hold the edge of the main control circuit 30, completing the vertical locking. This multi-fixing method, through surface support, groove positioning, and point locking, forms a three-dimensional locking of the main control circuit 30, making it difficult to shake or shift in any direction, greatly enhancing the overall impact and vibration resistance of the equipment.

[0061] Furthermore, in one embodiment of the present invention, to ensure that the drive mechanism 61 remains stable when the equipment is subjected to impact or vibration, a fixing structure is carefully designed on the inner wall of the receiving chamber. Specifically, the side of the central partition 121 facing the receiving chamber is provided with a connecting portion 125 (such as a screw post) for fixing the drive mechanism 61, and the drive mechanism 61 is provided with lugs 611 with mounting holes on both sides. The drive mechanism 61 passes through the mounting holes and is fixed by fasteners connected to the connecting portion 125. During installation, simply align the lugs 611 of the drive mechanism 61 with the connecting portion 125, and tighten the fasteners (such as screws) through the mounting holes to firmly fix the drive mechanism 61. This fixing method ensures that the drive mechanism 61 will not produce displacement or abnormal noise when operating at high speed, thus guaranteeing the stability of power output.

[0062] Furthermore, in one embodiment of the present invention, in order to provide a rich and comfortable visual experience, the visual prompting component 20 is carefully designed. Specifically, the visual prompting component 20 includes a plurality of warning lights 21 arranged linearly on the control circuit and facing the upper cover 11, and a plurality of low beam lights 22 arranged in an array on both sides of the warning lights 21. The inner surface of the upper cover 11 is provided with a transparent rectangular frame 111 corresponding to each warning light 21 and a lens 112 corresponding to each low beam light 22. The inner surface of the upper cover 11 has a plurality of honeycomb units 113 arranged in an array for softening light and directing light in the area outside the transparent rectangular frame 111 and the lens 112. Specifically, on the main control circuit 30, the light-emitting elements facing the upper cover 11 are divided into two groups: one group consists of multiple warning lights 21 arranged linearly to display specific information, such as battery level (e.g., 4 lights represent full charge), focus time countdown, etc.; the other group consists of multiple low-beam lights 22 arranged in an array on both sides of the warning lights 21 to create ambient lighting effects, such as the aforementioned breathing light. Corresponding to these lights, the inner surface of the upper cover 11 has a precise optical structure design. A transparent rectangular frame 111 is provided at the position corresponding to each warning light 21 to ensure that the warning information is clearly identifiable. A lens 112 is provided at the position corresponding to each low-beam light 22 to focus or scatter the light, making the light effect more uniform and softer. Furthermore, in other areas of the inner surface of the upper cover 11 (i.e., outside the transparent rectangular frame 111 and the lens 112), multiple honeycomb units 113 arranged in an array are integrally formed. These honeycomb structures not only achieve maximum structural strength with minimal materials, effectively enhancing the pressure resistance of the top cover 11, but more importantly, they effectively diffuse and soften light emitted from the inside. This effectively softens stray light scattered from the main control circuit 30 and directs the light, avoiding glaring direct light spots and making the light output softer and more uniform, greatly improving the user's visual comfort.

[0063] Furthermore, in one embodiment of the present invention, the power supply component 40 includes a battery 41 electrically connected to the main control circuit 30 and a charging module 42, with the battery 41 disposed between the main control circuit 30 and the drive mechanism 61; the charging module 42 includes a charging spring 421 housed in the receiving cavity of the lower cover 12 and electrically connected to the main control circuit 30, and a magnetic attracting piece 422 disposed on the outer wall of the lower cover 12; the outer wall of the lower cover 12 is provided with a charging port 126 for the charging spring 421 to extend out, a fixing groove 127 for accommodating and fixing the magnetic attracting piece 422, and a positioning groove 128 for positioning an external charger; the magnetic attracting piece 422 is provided with a reserved hole 4221 corresponding to the charging port 126 and a positioning hole 4222 corresponding to the positioning groove 128. The positioning hole 4222 and the positioning groove 128 are provided as described above. When the external magnetic charger approaches the charging area of ​​the device, the magnetic force of the magnetic iron piece 422 will automatically guide the charger to be precisely aligned and firmly attracted, eliminating the need for laborious searching and alignment. At the same time, the positioning pin on the charger will be inserted into the positioning slot 128 to ensure precise connection of the positive and negative poles, avoiding the risk of reverse insertion. This makes the charging operation extremely easy and convenient, greatly improving the convenience of the charging operation and the user experience.

[0064] Furthermore, in one embodiment of the present invention, to facilitate user operation, a control component 50 is typically and carefully provided on the side of the attention assist device. Specifically, at least one button slot 129 penetrating through the inside and outside is provided on the side wall of the lower cover 12. The control component 50 includes a pressable control button 51 housed in each button slot 129, and a switch circuit board 52 vertically connected to the main control circuit 30 and corresponding to the position of the control button 51. The switch circuit board 52 is provided with a control switch 521 corresponding to the position of the control button 51. The middle partition 121 is provided with multiple clamping plates 1211 for clamping and fixing each switch circuit board 52. The lower end of each switch circuit board 52 is clamped between two clamping plates 1211, and the upper end is fixed and electrically connected to the main circuit. Specifically, the control component 50 includes a pressable control button 51 and a small switch circuit board 52. The control button 51 is housed in the button slot 129. The switch circuit board 52 is mounted perpendicular to the main control circuit 30, and a control switch 521 (such as a surface-mount tactile switch) is soldered onto it, with its position precisely corresponding to the control button 51. To secure this vertical switch circuit board 52, multiple locking plates 1211 are provided on the central partition 121. The lower end of the switch circuit board 52 is tightly clamped by two locking plates 1211, while its upper end is fixed to the main control circuit 30 and electrically connected via pins or soldering. This two-point fixing method effectively prevents the switch circuit board 52 from shaking or tilting due to force, ensuring that the control switch 521 can be continuously and reliably triggered, significantly extending the service life of the control component 50.

[0065] Furthermore, in one embodiment of the present invention, the transmission mechanism 62 includes a slider 621 connected to the drive mechanism 61 and a rotating arm 622 slidably connected to the slider 621. The rotating arm 622 is provided with a groove 6221 extending along its length direction. The slider 621 is accommodated in the groove 6221 and can slide along the groove 6221. The touch mechanism 63 includes an elastic element 631 connected to a fixed post provided on the top surface of one end of the rotating arm 622 and a touch element 632 detachably connected to the end of the elastic element 631. The touch element 632 extends out of the plane where the bottom end of the housing 10 is located. Specifically, the rotational motion of the drive mechanism 61 is transmitted through the transmission mechanism 62 and converted into the circular motion of the touch mechanism 63. The transmission mechanism 62 consists of a slider 621 and a rotating arm 622. The slider 621 is fixed to the end of the drive shaft extending from the receiving chamber and rotates with the drive shaft. The rotating arm 622 has a groove 6221 extending along its length, within which the slider 621 is housed. When the slider 621 rotates, it pushes the sidewall of the groove 6221 of the rotating arm 622, thereby causing the entire rotating arm 622 to rotate around the center of the drive shaft. The touch mechanism 63 is connected to the rotating arm 622 and consists of an elastic element 631 (such as a short spring) and a touch element 632. A fixed post is located on the top surface of one end of the rotating arm 622; one end of the elastic element 631 is connected to this fixed post, and the other end is detachably connected to the touch element 632. The touch element 632 is a small component that comes into contact with the user's skin. It can be made of different materials such as skin-friendly silicone, hard plastic, or metal ball bearings to provide different tactile experiences. Its detachable design allows users to replace it or clean and disinfect it according to their preferences. The presence of the elastic element 631 provides a buffer when the touch element 632 contacts the user, resulting in a softer touch and avoiding the discomfort caused by rigid contact. It also adapts to uneven contact surfaces, enhancing the overall comfort of the experience. To ensure functionality, the end of the touch element 632 extends beyond the plane of the bottom of the housing 10, ensuring effective contact when the device is placed on the skin.

[0066] Furthermore, in one embodiment of the present invention, to allow users to customize the amplitude of haptic feedback, a corresponding adjustable rotation radius function is designed, as described above. Figure 7As shown, specifically, the bottom of the slider 621 is provided with a rectangular groove 6211, and an elastic spring piece 6212 protruding outward is provided in the rectangular groove 6211. The inner wall of the slide groove 6221 is provided with a plurality of slots 6222 that engage with the elastic spring piece 6212 along its length direction. The rotating arm 622 is locked by the engagement of the elastic spring piece 6212 with any slot 6222, thereby determining the rotation radius of the touch element 632 relative to the drive shaft in the drive mechanism 61. Specifically, the elastic spring 6212 is made of plastic. When the rotation radius of the rotating arm 622 needs to be adjusted, the user can apply a pulling or pushing force along the length of the rotating arm 622. Under the action of the external force, the elastic spring 6212 is compressed and retracts, disengaging from the current slot 6222, allowing the rotating arm 622 to slide along the slider 621. When the elastic spring 6212 aligns with one of the slots 6222, it will engage with the slot due to the elastic force, thus locking the slider 621 in the new position within the rotating arm 622. The different locked positions of the rotating arm 622 mean that the rotation radius of the touch element 632 at its end relative to the center of the drive shaft is different. The larger the radius, the wider the circumferential movement range of the touch element 632, and the more obvious the tactile sensation for the user. The smaller the radius, the finer the circumferential movement range of the touch element 632, and the lighter the tactile sensation. This greatly enhances the adaptability of the product and meets the personalized needs of different users in different scenarios.

[0067] Furthermore, in another preferred embodiment of the present invention, in order to achieve automatic adjustment of the rotation radius, a corresponding automatic adjustable design radius function is provided, referring to... Figures 8-10As shown, specifically, the transmission mechanism 62 also includes a radius adjustment mechanism 623 mounted on the rotating arm 622 and rotating together with the rotating arm 622; the radius adjustment mechanism 623 includes a drive motor 6231 electrically connected to the main control circuit 30, a lead screw 6232 arranged radially along the slider 621 and connected to the output shaft of the drive motor 6231 for rotation, a support base 6233 arranged at both ends of the lead screw 6232 and fixedly connected to the rotating arm 622, a sliding nut 6234 passing through the lead screw 6232 for axial movement, and a connecting piece 6235 connected to the sliding nut 6234 and the slider 621 respectively. Furthermore, the slider 621 includes a main body 6213 connected to the output shaft of the first drive mechanism, and a sliding part 6214 disposed in the slide groove 6221 and perpendicularly connected to the main body 6213; the support base 6233 includes a base plate 62331 fixedly connected to the side wall of the rotating arm 622, two side plates 62332 perpendicular to both ends of the base plate 62331 and connected to both ends of the lead screw 6232, and a guide reinforcing rod 62333 connected to the two side plates 62332; the sliding nut 6234 passes through the guide reinforcing rod 62333, and the end of the sliding nut 6234 away from the lead screw 6232 is provided with a receiving groove 62341 for accommodating the connecting member 6235; the end of the connecting member 6235 near the sliding nut 6234 is provided with a connecting block 62351 accommodated in the receiving groove 62341, and the connecting member 6235 is provided with a receiving hole 62352 for accommodating the main body 6213 in the slider 621.

[0068] Specifically, the drive motor 6231 is an independent micro motor (such as a stepper motor or a DC motor with an encoder for precise control), electrically connected to the main control circuit 30, used to provide power for the telescopic movement. The support base 6233 is firmly mounted on the side wall of the rotating arm 622, and mainly includes a base plate 62331 fixedly connected to the side wall of the rotating arm 622 and two side plates 62332 perpendicularly connected to both ends of the base plate 62331. The lead screw 6232 is typically a threaded rod, supported at both ends by the two side plates 62332 of the support base 6233, and connected to the output shaft of the drive motor 6231, primarily arranged along the radial direction of the slider 621 (i.e., the length direction of the rotating arm 622). The sliding nut 6234 is mounted on the lead screw 6232. When the drive motor 6231 drives the lead screw 6232 to rotate, the sliding nut 6234 will move precisely linearly along the axial direction of the lead screw 6232 due to thread engagement, forming the core transmission unit that converts rotational motion into linear displacement. To ensure that the sliding nut 6234 does not move to either end of the lead screw 6232 and block or damage the mechanical structure, limit switches (microswitches) or optical / Hall sensors can be installed at both ends of the lead screw 6232. When the sliding nut 6234 moves to either end and triggers the limit switch, it sends an interrupt signal to the main control circuit 30. Upon receiving the signal, the main control circuit 30 immediately stops the drive motor 6231 from moving in that direction and forces it to reverse, providing a physical safety guarantee and serving as a calibration benchmark for the range of motion. Furthermore, to prevent dynamic imbalance caused by the radius adjustment mechanism 623 being located on one side wall of the rotating arm 622, radius adjustment mechanisms 623 can also be respectively provided on the side walls of both ends of the rotating arm 622, with opposite positions, thereby balancing the transmission mechanism 62. Furthermore, since the radius adjustment mechanism 623 may always rotate in the same direction, it may cause the wires electrically connected to the drive motor 6231 and the main control circuit 30 to become entangled and break. Therefore, in a preferred embodiment of the present invention, a slip ring assembly can also be provided, which is respectively connected to the drive motor 6231 and the main control circuit 30. The slip ring assembly includes a stator ring fixed on the housing and a rotor ring fixed on the slider 621 and in sliding electrical contact with the stator ring.

[0069] Furthermore, to prevent the sliding nut 6234 from losing its linear movement capability due to rotation along with the lead screw 6232, a guide reinforcing rod 62333 parallel to the lead screw 6232 is provided on the support base 6233. The sliding nut 6234 is also mounted on this guide rod, thus constraining it to only perform translational movement. Furthermore, to convert the linear displacement of the sliding nut 6234 into the radial extension and retraction of the rotating arm 622, one end of the connecting piece 6235 is connected to the sliding nut 6234 (e.g., inserted into the receiving groove 62341 of the sliding nut 6234 via a connecting block 62351), and the other end is connected to the main body 6213 of the relatively fixed slider 621 (e.g., sleeved on the main body 6213 via a receiving hole 62352). Therefore, when the main control circuit 30 sends a command to the drive motor 6231, the drive motor 6231 drives the lead screw 6232 to rotate. Under the constraint of the guide reinforcing rod 62333, the sliding nut 6234 moves axially along the lead screw 6232. Since the connecting piece 6235 connects the moving sliding nut 6234 to the relatively fixed slider 621, the movement of the sliding nut 6234 will have a reaction effect on the entire radius adjustment mechanism 623 and the fixed rotating arm 622, thereby pushing or pulling the rotating arm 622 to slide radially relative to the slider 621.

[0070] The main control circuit 30 is configured to independently control the drive mechanism and the drive motor 6231. This means that the attention assist device can control the rotational angular velocity and radial position of the rotating arm 622 in real time and with precision, allowing the rotation radius to change dynamically and continuously while rotating. For example, the main control circuit 30 can control the rotating arm 622 to extend outward at a uniform speed while maintaining rotation, forming a spiral trajectory; or it can periodically extend and retract during rotation, forming a petal-shaped trajectory, thereby creating extremely rich and complex tactile stimulation patterns.

[0071] Therefore, in this embodiment of the invention, by setting an independent drive mechanism and drive motor 6231, and the main control circuit 30 to perform independent or coordinated electronic control of the drive mechanism and drive motor 6231, the drive mechanism drives the slider 621 to rotate; at the same time, the drive motor 6231 mounted on the rotating arm 622 drives the sliding nut 6234 to move through the lead screw 6232, and reacts to the slider 621 through the connecting member 6235, thereby pushing the entire rotating arm 622 to slide radially relative to the rotation center, realizing stepless and continuous radius change, and can be changed in real time during the operation of the attention assist device. This enables the device to generate complex dynamic tactile stimulation modes such as spirals and pulsations, greatly enriching the user experience and solving the technical problems of the existing technology of single stimulation modes and primitive adjustment methods. By specifically designing the guide reinforcing rod 62333 on the support base 6233, and allowing the sliding nut 6234 to pass through both the lead screw 6232 and the guide reinforcing rod 62333, a stable and reliable linear transmission structure is constructed. The guide reinforcing rod 62333 effectively prevents the sliding nut 6234 from rotating, ensuring that rotational motion can be efficiently and accurately converted into linear motion. Furthermore, the connection between the connector 6235 and the main body 6213 of the slider 621 via the receiving hole 62352, and the connection block 62351 of the connector 6235 housed within the receiving groove 62341 of the sliding nut 6234, ensures the compactness and reliability of the transmission chain, providing structural assurance for precise radius control.

[0072] Furthermore, in one embodiment of the present invention, to further enhance the user experience, the touch element 632 is designed to be detachable. The bottom surface of the rotating arm 622 is provided with a fixing through hole. The touch mechanism 63 also includes a detachable spare element 633, which has the same structure as the touch element 632 but is made of a different material and is mounted on the fixing through hole. This allows users to replace the touch element 632 with different materials or shapes according to their personal preferences, satisfying different tactile preferences. For example, a skin-friendly silicone element is provided as standard, while a textured plastic element or a cool metal ball is provided as a spare element 633. When not in use, these spare elements 633 can be cleverly installed on a fixing through hole on the bottom surface of the rotating arm 622 for easy storage and to prevent loss. In addition, a rubber ring 13 is provided at the edge of the lower cover 12 near the rotating chamber. The rubber ring 13 prevents direct contact between the edge of the lower cover 12 and the palm, and enhances the tactile feel. Furthermore, the slider 621 and the drive mechanism 61 can be connected and fixed by means of snap-fit, thread, etc. In one embodiment of the present invention, the transmission mechanism 62 also includes a screw, bolt or other fastener for fixing the slider 621 and the drive mechanism 61. In this case, due to the fixed through hole provided above, during assembly, the slider 621 and the drive mechanism 61 can be fixed by passing the fastener through the fixed through hole first, and then the spare component 633 can be installed on the fixed through hole to complete the assembly of the moving parts in the rotating chamber.

[0073] In summary, the attention-enhancing device integrating tactile feedback and visual cues in the above embodiments of the present invention, through the coordinated control of the main control circuit to generate a tactile feedback component with regular circular motion and a visual cues component providing rhythmic light effects, achieves synchronous guidance of both tactile and visual sensory channels. This creates a gentle, non-invasive, and continuous focus anchor for the user, thereby greatly improving the efficiency and depth of guiding the user into and maintaining a state of focus. Furthermore, by setting a central partition inside the housing, dividing the internal space into a receiving chamber for housing the main control circuit and drive mechanism and a rotating chamber for housing the transmission mechanism, it achieves dynamic... The physical isolation between the mechanical components and the static precision electronic components effectively avoids the impact of mechanical vibration and electromagnetic interference on circuit stability. A transmission mechanism consisting of a slider and a rotating arm with a groove smoothly converts the rotational motion of the drive mechanism into the circular motion of the touch mechanism within a predetermined plane. Connecting the touch mechanism with an elastic element achieves a slow and gentle tactile feedback. Furthermore, by incorporating a radius adjustment mechanism (driven by a lead screw to extend and retract the rotating arm), decoupling and dynamic coordinated control of the rotational motion and radius adjustment are achieved, enabling the touch mechanism to depict complex motions such as spirals and pulsations. The touch mechanism features a programmable two-dimensional dynamic trajectory. An elastic spring on the slider, engaging with multiple slots on the inner wall of the rotating arm's slide, allows for adjustable locking of the touch mechanism's rotation radius. A composite optical structure, consisting of a transparent rectangular frame corresponding to the warning light, a lens corresponding to the low beam, and honeycomb units distributed throughout the remaining areas, achieves precise control and softening of light, ensuring clear visibility of status information while creating a uniform, comfortable, and glare-free ambient lighting effect. Furthermore, reinforcing ribs and limiting buckles on the inner wall of the receiving cavity, precisely integrated with the support grooves on the edge of the main control circuit board... In conjunction with other technologies, a robust fixing method with multi-point support and multi-directional limiting is achieved, ensuring the absolute stability of the core circuit under complex working conditions such as impact and vibration. By adopting a magnetic charging solution that includes charging springs, magnetic iron plates, positioning holes, and positioning slots, a convenient, safe, and blind-operable charging experience is achieved. Furthermore, the design of detachable touch components, the provision of through holes for fixing spare components on the rotating arm, and the placement of rubber rings on the edge of the lower cover allow users to personalize their choice of tactile materials, facilitate the convenient storage of accessories, and enhance the tactile feel of the device. This solves the problems of the limited modes and limited effects of existing focus assistive tools.
