Abstract
Description
Technical Field
[0001] This utility model relates to the field of communications, and in particular to an interactive anti-accidental touch device, a smart ring, and a smart device. Background Technology
[0002] With the continuous development and miniaturization of chip and smart technologies, the application prospects of smart rings, smart finger rings, and smart styluses as interactive carriers are gradually expanding, and they are expected to become one of the important human-computer interaction media in the future. However, since rings need to be worn on the body, they face many challenges in daily use. For example, accidental touches can easily occur when users take items out of their pockets, put on clothes, or when clothing rubs against the ring surface, thus affecting the accuracy of the interaction. Therefore, how to achieve an efficient anti-accidental touch design in smart devices such as smart rings has become an urgent problem to be solved.
[0003] Currently, chip manufacturers have developed ultra-small photosensitive elements (photoelectric sensors), whose working principle is similar to the photosensitive sensor on the bottom of a mouse. This sensor uses a reverse sensing design and covers the photosensitive unit with a lens. When a finger touches the surface, the photosensitive unit can sense the movement and generate a cursor movement signal. However, this type of photoelectric sensor can only detect the movement of objects on the surface and cannot distinguish whether the contacting object is a finger or other human tissue or another object. Therefore, when the surface of a ring rubs against clothing or other objects, the sensor may erroneously trigger the interaction signal, leading to a degraded user experience.
[0004] To address this issue, an interactive anti-mistouch design is needed that can effectively distinguish between genuine user touches and unintended contact, thereby improving the accuracy of interaction, reducing accidental touches, and optimizing the overall user experience.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Figure 1 This diagram illustrates the structural framework of an interactive anti-accidental touch device according to an embodiment of the present invention. Figure 1 As shown, the interactive anti-accidental touch device 100 includes:
[0043] Optoelectronic device 101 is used to detect movement information of a touch object on the surface of the interactive anti-mistouch device;
[0044] At least one touch sensing device 102 is disposed around the photoelectric device for sensing the contact information of the touch object on the surface of the interactive anti-mistouch device;
[0045] The control unit 103, connected to the photoelectric device 101 and the touch sensor 102, is used to set the working mode of the photoelectric device to a first mode when the touch sensor detects that the contact information of the touch object meets a first preset condition. Specifically, the photoelectric device setting mode is as defined in this application, where the touch sensor can be used alone to prevent accidental touches, that is, the working mode of moving the cursor is activated only when the photoelectric device senses light and the touch sensor simultaneously senses light.
[0046] In one embodiment, the control unit 103 is further configured to set the photoelectric device 101 to the second working mode when the touch sensing device 102 detects that the contact information of the touch object meets the second set condition.
[0047] In one embodiment, the photoelectric device 101 is mainly used to detect the movement information of the touch object on the surface of the interactive anti-mistouch device. That is, when the user's finger or other contact target slides on the surface of the ring, the device can capture its movement trajectory and convert it into interactive commands, such as cursor movement, scrolling, dragging, etc. The touch sensing device 102 is arranged around the photoelectric device 101. Its function is to sense the contact information of the touch object. Using technologies such as capacitive sensing, skin resistance measurement, or pressure sensing, it can distinguish between human finger touch and non-biological material contact, thereby reducing the probability of mistouch. The control unit 103 is responsible for managing the cooperative work of the photoelectric device 101 and the touch sensing device 102. When the touch sensing device 102 detects that the contact information of the touch object meets the first set condition (such as continuous touch for more than a set time or detection of a contact signal that matches the human skin resistance), the control unit 103 sets the working mode of the photoelectric device 101 to the first mode, that is, the normal working state of the photoelectric device 101, activates the photoelectric detection function, and puts the system into a normal interactive state. In addition, in some implementations, if the touch sensing device 102 detects that the contact information of the touch object meets the second set condition (such as the pressure exceeding a preset threshold or double-click to confirm the touch), the control unit 103 can adjust the photoelectric device 101 to the second mode, that is, enter the low power consumption or specific interaction mode, to adapt to different usage scenarios, optimize power consumption management and improve user experience.
[0048] The technical solution provided by this utility model, by combining photoelectric sensors and touch sensing technology, significantly reduces the probability of false triggering and improves the accuracy and reliability of interaction. The dual verification mechanism of capacitive sensing and photoelectric detection ensures that only genuine finger touches trigger interaction commands, effectively reducing the occurrence of misoperations. Regarding power consumption optimization, the power consumption of the touch sensing device is controlled between 3-5uA, while the power consumption of the photoelectric device could reach 10-50uA or more before optimization. Devices such as smart rings and smart pens have very small battery capacities and require power consumption optimization to ensure extended usage time. Through dynamic power management, the system can enter an ultra-low power mode when no finger touch is detected, significantly reducing overall power consumption and extending the device's battery life. Furthermore, this solution greatly enhances the user experience through precise touch recognition and anti-mistouch mechanisms. It can effectively prevent mistouches on both non-conductive and metal rings, demonstrating broad applicability.
[0049] Figure 2 This diagram illustrates the structural framework of another interactive anti-accidental touch device provided in an embodiment of the present invention, as shown below.Figure 2 As shown, the control unit of the device can be an MCU or other type of control chip. It detects the movement information on the surface of the photoelectric device and generates interactive instructions. The interactive instructions include, but are not limited to, cursor movement, dragging, scrolling, and key operation.
[0050] In one embodiment, the touch sensing devices are disposed around the periphery of the photoelectric device, and the periphery includes at least one side, two sides, three sides, or all four sides. Depending on the application scenario, different arrangements of the touch sensing devices can be implemented. A scheme with multiple touch sensing devices on each side can effectively improve the system's ability to prevent accidental touches, avoiding misoperations caused by the limitation of the touch area, thereby optimizing the user experience. This layout not only increases the touch area coverage of the ring or other devices but also allows for flexible adjustment of touch sensitivity according to different actual needs, adapting to more complex operating scenarios.
[0051] In one embodiment, the peripheral touch sensing device disposed on the optoelectronic device includes a touch capacitive sensing copper foil 1021. Specifically, the touch capacitive sensing copper foil can be used to sense touch signals through the principle of capacitance. When a user's finger or other conductive object touches or approaches the touch area, the capacitance of the human body or object affects the electric field distribution of the copper foil, producing a slight capacitance change. The touch capacitive sensing copper foil around the optoelectronic device can detect this capacitance change and convert these changes into identifiable signals through a capacitance sensor.
[0052] In one embodiment, the touch object is a designated finger of the human body; the touch sensing device uses skin resistance measurement technology to detect the resistance characteristics of the touch object in order to distinguish human skin from other non-biological materials.
[0053] In one embodiment, the touch sensing device includes a fingerprint recognition unit 1022, which is used to detect the touch information of a touch object as the touch information of a set finger, and set the operating mode of the photoelectric device to a first mode.
[0054] In one embodiment, the fingerprint recognition unit 1022 operates using fingerprint scanning technology based on capacitance or optical principles. Capacitive fingerprint recognition technology acquires a fingerprint image by sensing changes in capacitance on the surface of the finger. Specifically, the sensor array of the fingerprint recognition unit 1022 consists of multiple tiny capacitive sensors. When a finger touches the sensor surface, the ridges and valleys on the finger generate different capacitance values. Because the conductivity of skin differs from that of environmental objects, these capacitance values can be compared with a preset fingerprint template to identify the finger. Optical fingerprint recognition, on the other hand, uses a light source to illuminate the finger surface and acquires the reflected image information through a camera. Image processing algorithms are then used to analyze the texture of the fingerprint ridges and valleys to identify the fingerprint pattern.
[0055] In this embodiment, when the fingerprint recognition unit 1022 detects specific contact information from a designated finger, it sends a signal to the main controller, including the control unit, indicating that the touch comes from a user-authorized finger (e.g., a user-specified finger). At this time, the main control unit sets the operating mode of the photoelectric device to a first mode based on the fingerprint recognition result to activate the photoelectric detection function and begin normal interactive operations. In this way, fingerprint recognition not only ensures the uniqueness and security of the touch but also precisely controls the device's interactive functions, activating the photoelectric device only when a designated finger is recognized, further improving device security and user experience.
[0056] In one embodiment, the touch sensing device includes a pressure sensor 1023 for detecting the pressure intensity applied by the touch object, and when the pressure exceeds a set threshold, the operating mode of the photoelectric device is set to a first mode.
[0057] Specifically, pressure sensors sense pressure changes based on the piezoelectric effect or the principle of resistance change. In a piezoelectric pressure sensor, when pressure is applied to the sensor surface, the piezoelectric material inside the sensor deforms, generating an electric charge. This charge change is proportional to the applied pressure. The sensor converts the charge signal into a voltage signal through electrodes, which is then transmitted to the main control unit for analysis and processing. The system determines the pressure magnitude based on the strength of the voltage signal and compares it with a set threshold. Alternatively, pressure sensors based on the principle of resistance change can also be used to sense pressure. When pressure is applied to the sensor surface, the resistive material inside the sensor deforms, causing a change in resistance. The sensor determines the applied pressure magnitude by monitoring this resistance change. When the applied pressure exceeds a preset threshold, the sensor outputs an electrical signal, indicating that the trigger condition has been met.
[0058] In one embodiment, these sensing principles of the pressure sensor enable precise detection of the pressure applied by the touch object, ensuring that the photoelectric device's operating mode is triggered only when the pressure exceeds a set threshold. This avoids erroneous operations caused by slight contact or environmental noise, ensuring that the system only initiates normal interaction when the user explicitly applies pressure. This significantly enhances the device's resistance to erroneous operations and provides a more accurate and reliable interactive experience.
[0059] Figure 3 This diagram illustrates the structure of a smart ring according to an embodiment of the present invention. Figure 4 This diagram shows an exploded view of the structure of a smart ring according to an embodiment of the present invention. Figure 3 , 4As shown, the smart ring includes an outer shell 301, a window 302, an inner shell 303, and an interactive anti-accidental touch device 304. The interactive anti-accidental touch device 304 includes a photoelectric device 3041 and a touch sensing device 3042.
[0060] The smart ring includes an interactive anti-accidental touch device 304, which is the aforementioned interactive anti-accidental touch device, and its specific details will not be repeated here.
[0061] The outer casing 301 of the smart ring has a window 302. The interactive anti-mistouch device 304 is installed in a position adapted to the window 302, so that the photoelectric device and touch sensing device of the interactive anti-mistouch device 304 can come into contact with the touch object. In the adapted position, the touch part can also be placed on the outside of the window.
[0062] In one embodiment, if the outer shell of the smart ring is made of conductive material, an isolation touch sensing unit is provided around the interactive anti-accidental touch device. Figure 3 , 4 (Not shown), used to isolate the touch sensing device from the outer shell of the smart ring. Specifically, the isolation touch sensing unit can be at least one insulating strip or insulating sheet, used to prevent the touch sensor from conducting electricity with the conductive metal shell of the smart ring.
[0063] In one embodiment, a touch sensor is arranged around the photosensitive element. Since the photosensitive element is very small and mounted on the surface of the ring, there is still ample space around it. Therefore, copper foil or other metal sensing devices can be arranged around the photosensitive element, and these sensing devices are connected to the touch sensor. When the photosensitive sensor detects movement on the surface, the main control device can determine whether to send relevant control commands based on whether the touch sensor outputs a touch signal. These commands include cursor movement, dragging, scrolling, left-clicking, right-clicking, page turning, etc. In this way, only when a finger or human skin touches the surface will it be recognized as a genuine touch command, greatly reducing the probability of accidental touches.
[0064] The smart ring provided by this utility model has the following advantages: 1. It greatly reduces the probability of accidental touches. By combining capacitive sensing and photoelectric devices, it can ensure accurate touch detection. 2. It greatly reduces device power consumption. With only photoelectric devices, the photoelectric device needs to maintain a certain refresh rate to ensure that finger touches can be detected, and its power consumption can reach 10-50uA or even higher. In contrast, the power consumption of touch sensing devices is only 3-5uA. Thus, after applying touch sensing devices, they can be used as a prerequisite judgment condition. When the finger is not touching, the photoelectric device is set to ultra-low power consumption. When the finger touches the surface, the touch sensing device detects the finger touch. After receiving the signal from the touch sensing device, the main controller sets the photoelectric device from ultra-low power consumption mode to standard working mode. After the finger leaves, the main controller sets the photoelectric device to ultra-low power consumption mode based on the signal detected by the touch sensing device. This greatly reduces the power consumption originally required for the photoelectric device to detect the finger. Due to the small size of the ring and the limited battery capacity, this can improve the ring's battery life.
[0065] In one embodiment, for ring surfaces made of non-conductive materials such as ceramics or plastics, capacitive touch-sensitive copper foil can be laid on both sides or the four edges of the photosensitive device to ensure that a capacitive sensing signal is always triggered when the user touches the photosensitive device. This design, by setting a capacitive sensing layer around the photosensitive device, effectively enhances the sensitivity and accuracy of touch, thereby reducing the probability of accidental touches and ensuring the reliability of the interaction.
[0066] In one embodiment, for a metal ring surface, the touch sensor needs to be electrically isolated from the surrounding metal parts to ensure that the metal area is insulated from other metal parts of the ring. The isolated metal area is then connected to the capacitive sensing circuit, ensuring that touch signals from the metal area surrounding the photoelectric device are only recognized. This design effectively prevents interference from other metal parts of the ring, ensuring that the system can accurately sense the user's touch operations even in highly interference environments, thus improving the stability and reliability of the interactive experience.
[0067] This utility model also provides a smart device, including the interactive anti-accidental touch device described above.
[0068] In one embodiment, the smart device can be a smart stylus. Integrating an interactive anti-mistouch device into the stylus effectively prevents accidental operations, especially when high-precision drawing or writing is required. By integrating optoelectronic devices and touch sensors, the stylus can accurately identify the user's finger contact and control cursor movement accordingly, avoiding unnecessary accidental triggering and incorrect drawing. Simultaneously, the control unit can sensitively adjust the operating mode of the optoelectronic devices based on touch intensity and location, ensuring responsiveness and accuracy during drawing.
[0069] In one embodiment, the smart device can be a controller for a virtual reality (VR) device. Incorporating an anti-accidental touch device into the VR device controller helps users interact more naturally with the virtual environment when using a VR headset, avoiding unintentional touches or gestures that trigger operations accidentally. The anti-accidental touch device can detect hand movements and accurately identify user intentions, thereby enhancing the immersion and interactivity of the virtual reality experience.
[0070] In one embodiment, the smart device can be a controller for an augmented reality (AR) device. In the controller of an AR device, the interaction anti-mistouch device will provide more accurate gesture recognition and touch feedback. For example, in smart glasses, users may perform various operations using their head or gestures. The interaction anti-mistouch device can identify the user's true interaction intent through a combination of photoelectric sensing and touch sensing, avoiding unnecessary misoperations and improving the smoothness and naturalness of the AR experience.
[0071] This utility model also provides an interactive anti-accidental touch method, including: sensing whether there is finger or human skin contact; if finger or human skin contact is detected, activating the photosensitive device to a first working mode, which is a standard working mode; if no finger or human skin contact is detected, setting the working state of the photosensitive device to a second working mode, which is a non-standard working mode, specifically an ultra-low power mode; specifically, if the sensing of whether there is finger or human skin contact ceases, the touch control ends, and the device is automatically adjusted back to the ultra-low power mode.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
