Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for controlling a remote control, and the remote control itself. Background Technology

[0002] Currently, with the deepening of population aging, smart TVs have become an important medium for the daily entertainment and information access of the elderly. However, existing TV remote control technology has failed to fully adapt to the physiological characteristics and usage needs of the elderly, resulting in many pain points. For example, insufficient eye protection functions lead to high eye health risks; prolonged sitting is a prominent issue, resulting in a lack of health management; and emergency assistance and ease of use are inadequate. Therefore, developing a smart remote control that integrates eye protection, sedentary intervention, and emergency assistance, while being simple to operate and adapted to the usage habits of the elderly, has become an urgent need to solve the pain points of TV use for the elderly and improve their quality of life, possessing significant practical value and market potential.

[0003] In related technologies, a combination scheme of a basic eye-protection remote control and a simple emergency call device is disclosed. After the remote control is turned on, the sensor module is activated and continuously collects data through a distance sensor and a light sensor. When the sensor data reaches a fixed threshold, a fixed brightness and contrast adjustment command is sent to the TV. A simple timer function is used to remind users of prolonged sitting. After pressing the emergency button, a preset help message is sent to the bound mobile phone via Bluetooth.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: The relevant technologies can only adjust fixed parameters and cannot achieve interactive intervention on the user's health status.

[0029] S103, the processor determines whether the user is in a sedentary state based on the acceleration signal, and executes the sedentary intervention process if the user is in a sedentary state.

[0030] S104, the processor responds to the user's trigger operation on the preset function key on the remote control and executes the corresponding health protection function; the health protection function includes eye protection interactive function and emergency call function.

[0031] In this embodiment, multi-dimensional automatic health protection is achieved by collecting distance, light, and acceleration signals, and performing parameter adjustments, sedentary behavior assessment, and interactive intervention. Combining distance and light intensity signals to generate display parameter adjustment instructions dynamically adapts to the viewing environment and prevents eye strain. Judging sedentary behavior based on acceleration signals and executing sedentary intervention procedures guides users to interrupt prolonged sitting. Health protection functions triggered by preset function keys can execute eye-protection interactive functions and emergency call functions, enabling users to quickly and easily obtain help or initiate health intervention when needed. Therefore, this embodiment, through automatic multi-signal acquisition and processing, comprehensive environmental and behavioral judgment, closed-loop intervention process execution, and one-click integration of core functions, enables interactive intervention in the user's health status.

[0032] Optionally, combined Figure 2 As shown, the remote control 10 is communicatively connected to the TV 20 and the mobile app 30. Through the linkage between the remote control 10, the TV 20, and the mobile app 30, functions such as adjusting display parameters, controlling playback, transmitting emergency information, and synchronizing health data can be achieved, creating a comprehensive health protection and convenient user experience.

[0035] Optionally, the main body of the remote control 101 adopts an anti-slip curved design that conforms to the gripping habits of the elderly. More specifically, the main body of the remote control 101 measures 150mm × 50mm × 30mm, and features large buttons (diameter ≥ 12mm) on its surface, including core function buttons such as the "eye protection interaction button" and the "SOS emergency call button," as well as simple TV control buttons (power, channel, volume). The buttons are clearly labeled and have a prominent tactile feel, making them easy for the elderly to identify and press.

[0036] Optionally, the remote control body 101 has a built-in micro SIM card. After pressing the SOS button, it directly dials the preset emergency contact number (such as children, community service center) and sends a location SMS at the same time, which is suitable for elderly people who do not use smartphones.

[0037] Optionally, the multi-sensor module 102 includes: a distance sensor 111, a light sensor 112, an acceleration sensor 113, and an auxiliary sensor 114.

[0038] Optionally, the distance sensor 111 is an infrared distance sensor (model GP2Y0A21YK) installed in the middle of the front end of the remote control. The distance measurement range is 0.1 to 2.5 meters and the distance measurement accuracy is ±0.05 meters. By detecting the straight-line distance between the user and the TV screen, it outputs a digital signal to the main control unit 108.

[0039] Optionally, the distance sensor 111 employs infrared filtering technology to avoid interference from the light from the television screen and improve the accuracy of distance measurement.

[0040] Optionally, the distance sensor 111 also includes an ultrasonic distance sensor (model HC-SR04). The ultrasonic sensor has a wider ranging range (0.2 to 4 meters), stronger resistance to light interference, is suitable for home environments with complex lighting, and has a ranging accuracy of ±0.1 meters, which can meet the needs of elderly users.

[0041] Optionally, the light sensor 112 is a photoresistor sensor (model LDR5516) integrated on the top of the remote control. It can sense ambient light intensity in the range of 0 to 10000 lux with an accuracy of ±50 lux, and collects ambient light data in real time to provide a basis for adjusting the TV display parameters.

[0042] Optionally, the light sensor 112 is equipped with a light shield design to prevent detection errors caused by direct sunlight and ensure that the ambient light intensity data is accurate and reliable.

[0043] Optionally, the accelerometer 113 is a triaxial accelerometer (model MPU6050) built into the middle of the remote control with a sampling rate of 100Hz. By detecting the duration of the remote control's stationary state and combining it with the TV playback status, it can determine whether the user has been sitting for a long time.

[0044] Optionally, the auxiliary sensor 114 has a built-in miniature microphone (sensitivity -42dB, frequency response 20Hz to 20kHz) for transmitting ambient sound during SOS emergency calls; it also integrates a Bluetooth positioning module to support distance sensing positioning with a mobile app.

[0045] Optionally, the auxiliary sensor 114 also includes a GPS-assisted positioning module. The GPS module provides more accurate absolute positioning (accuracy ±5 meters), making it more suitable for large homes if the remote control is lost by an elderly person while moving around in large spaces such as the living room or dining room.

[0046] Optionally, the interactive control module 103 includes a core interactive button 121, a vibration reminder unit 122, and a status indicator unit 123.

[0047] Optionally, the core interactive buttons 121 include: an eye protection interactive button and an SOS emergency call button. The eye protection interactive button can be set as a large, raised red button to start the eye protection program with one click and trigger the TV camera to activate the blink detection function; the SOS emergency call button can be set as an orange anti-slip button, which can be pressed and held for 3 seconds to trigger emergency help (to avoid accidental touches) and supports one-click quick call.

[0048] Optionally, the vibration reminder unit uses a dual-mode vibration motor (supporting gentle vibration and enhanced vibration), switching vibration modes according to different reminder scenarios, with moderate vibration intensity (≤0.5g) to avoid startling the elderly.

[0049] Optionally, the status indicator unit 123 has three built-in LED indicators (green - normal operation, yellow - reminder status, red - emergency status), and is equipped with a voice prompt module (volume adjustable, voice clear and slow) to provide synchronous feedback on operation results and device status.

[0050] Optionally, the voice prompts use a slow, clear female voice (speech rate ≤180 words / minute), and the volume supports 3 levels of adjustment (30dB / 40dB / 50dB) to suit the hearing characteristics of the elderly; the vibration intensity has been tested on elderly groups to avoid discomfort caused by excessive vibration, while ensuring the reminder effect.

[0051] Optionally, the wireless communication module 104 includes an infrared transmitting unit 131, a Bluetooth module 132, and a positioning assistance unit 133.

[0052] Optionally, the infrared transmitting unit 131 supports mainstream TV infrared communication protocols and is used to send commands such as display parameter adjustment, play / pause, and unlock verification to the TV.

[0053] Optionally, the preset unlocking actions (shaking, circling) for unlock verification are simple and easy to operate. The accelerometer 113 algorithm is optimized to reduce the required amplitude of the action (e.g., a shaking angle of ≥30° is sufficient for recognition). At the same time, an action timeout (10 seconds) is set to make it suitable for elderly people to operate.

[0054] Optionally, the Bluetooth module 132 adopts the Bluetooth 5.0 protocol (model HC-08) for wireless communication with TVs and mobile phone apps to achieve data synchronization and command transmission, with a communication distance of ≤10 meters and a latency of ≤10ms.

[0055] Optionally, the wireless communication module 104 also includes a radio frequency communication module (315MHz band). Radio frequency communication has stronger penetration and can penetrate obstacles such as walls, making it suitable for elderly people to use remote control to control the TV in different rooms, thus improving ease of use.

[0056] Optionally, the wireless communication module 104 also includes a Wi-Fi module (supporting the 802.11n protocol). Wi-Fi offers a longer communication range (≤30 meters) and a higher data transmission rate, making it suitable for large homes. It ensures stable interaction between the remote control, TV, and mobile app, and supports simultaneous connection of multiple devices.

[0057] Optionally, the sensor adopts an intermittent working mode (enters sleep mode when not collecting data in real time), and the Bluetooth module 132 switches to a low power state during data transmission intervals, with standby power consumption ≤5mA, extending battery life and reducing the charging frequency for the elderly.

[0058] Optionally, the positioning assistance unit 133 uses Bluetooth signal strength detection and a mobile APP to achieve remote control positioning with an accuracy of ±1 meter.

[0059] Optionally, the TV linkage unit 105 communicates with the TV. The TV needs to support infrared command reception and Bluetooth communication, have a built-in camera (for blink frequency capture) and eye protection program, and be able to receive remote control commands to adjust screen brightness and contrast, activate blink detection, pause / resume playback, and pop up an interactive task interface.

[0060] Optionally, the mobile health APP linkage unit 106 communicates with a mobile phone. The mobile phone supports Android and iOS systems and has the following functions: receiving SOS help information (including location and help prompts), playing home ambient sounds in real time, recording viewing time and sedentary intervention data, setting eye protection parameter thresholds, and receiving low battery reminders from the remote control.

[0061] Optionally, SOS distress messages and location data are transmitted in encrypted form (AES-128 encryption) and can only be received by authorized mobile apps to prevent privacy leaks; health data is stored locally and on the linked mobile phone and is not uploaded to the cloud to ensure data security.

[0062] Optionally, the power management module 107 uses a 3.7V rechargeable lithium battery (capacity 2000mAh), supports USB-C interface charging, has a low power detection function (triggers a reminder when the remaining power is ≤20%), standby power consumption ≤5mA, and normal use battery life ≥30 days.

[0063] Optionally, the main control unit 108 uses a low-power MCU chip (model STM32L476) as the core of the system, responsible for receiving data from various sensors, parsing operation instructions, controlling the coordinated work of various modules, and running threshold judgment algorithm, unlock verification algorithm and linkage control logic.

[0064] After the remote control provided in this embodiment is powered on, the power management module 107 supplies power to each module, and the main control unit 108 sends an initialization command: in the multi-sensor module 102, the distance sensor 111 sets the ranging threshold (1.5 meters), the light sensor 112 calibrates the initial value, the accelerometer 113 sets the sedentary judgment threshold (1 hour), and the microphone and positioning module enter the ready state; in the wireless communication module 104, the Bluetooth module 132 automatically searches for and connects to the bound TV and mobile APP, and establishes an encrypted communication link (communication delay ≤10ms); in the interactive control module 103, the LED indicator light is constantly green, the voice prompt "Device is ready", the vibration module performs a short press and a gentle vibration, and the feedback initialization is completed; at the same time, the remote control, TV and mobile APP are linked, the TV's eye protection program enters the standby state, and the mobile APP synchronizes the remote control's online status and battery information.

[0065] Optionally, based on the distance signal and the light intensity signal, an adjustment instruction for the display parameters of the television is generated, including: when the distance signal is less than a preset distance threshold, an adjustment instruction to reduce the screen brightness is generated based on the distance signal; when the light intensity signal is greater than a first light intensity threshold, an adjustment instruction to increase the screen contrast is generated; and when the light intensity signal is less than a second light intensity threshold, an adjustment instruction to reduce the proportion of blue light on the screen is generated.

[0066] In this embodiment, reducing screen brightness when the user is too close to the television prevents glare and eye strain caused by excessively strong and concentrated screen light due to close viewing distance. Increasing contrast when the environment is too bright enhances the distinction between the subject and background, helping users more easily identify content and counteracting ambient light interference. Reducing blue light when the environment is too dark minimizes melatonin suppression and potential photochemical damage to retinal cells, creating a more comfortable low-light viewing experience. Therefore, by dynamically and specifically adjusting based on real-time signals from two independent dimensions—viewing distance and ambient light—viewing conditions can be proactively optimized at the source to achieve eye protection.

[0067] In one specific embodiment, the distance sensor and light sensor collect data every second and transmit it to the TV and main control unit via Bluetooth module. The TV adjusts display parameters in real time according to preset logic: when the distance is <1.5 meters, the screen brightness is automatically reduced (reduced by 5% for every 0.1 meters closer, down to a minimum of 30%); when the ambient light intensity is >8000 lux (strong light), the screen contrast is increased by 10%-20%; when the ambient light intensity is <300 lux (weak light), the screen blue light ratio is reduced by 30%.

[0068] Optionally, determine whether the user is in a sedentary state, and if the user is in a sedentary state, execute a sedentary intervention process, including: determining the remote control status based on acceleration signals; determining that the user is in a sedentary state if the remote control has been inactive for a preset duration and the TV is in playback mode; determining the sedentary state level based on the duration of the sedentary state; and executing graded sedentary intervention based on the sedentary state level.

[0069] In this embodiment, the remote control status is determined based on the acceleration signal, enabling the correct triggering of sedentary intervention when the user is watching TV and has not moved for an extended period. This effectively eliminates invalid scenarios such as the user temporarily leaving the house or the TV being in standby or off. By implementing tiered sedentary intervention, the potential for user backlash and resistance from using the strongest measures all at once can be avoided. Gradually increasing intervention intensity ensures the effectiveness of health intervention while improving user-friendliness and acceptability. Mandatory interruption mechanisms can also be introduced at different levels of intervention, requiring users to perform specific actions to resume watching, thus elevating health reminders to behavioral constraints and increasing the probability of user physical activity.

[0070] In one specific embodiment, an accelerometer continuously monitors the remote control's status. If the remote control remains inactive for one hour (no button presses, no significant movement) while the TV is playing, the main control unit determines this as "prolonged sitting" and triggers a sedentary intervention process. Furthermore, the system can also acquire the duration of continuous TV playback and send a sedentary reminder command to the remote control after one hour, eliminating reliance on the remote control's operational status and adapting to scenarios where elderly people watch movies without holding the remote.

[0071] In one specific embodiment, the graded sedentary intervention includes: Level 1 reminder, Level 2 intervention, and unlocking and recovery. Under Level 1 reminder, the remote control initiates a gentle vibration (lasting 1 second, repeated twice with a 2-second interval), the yellow LED indicator flashes, and a voice prompt says, "You have watched for 1 hour, please get up and move around." If the user does not perform any operation (does not press any buttons, does not move the remote control), Level 2 intervention begins. The main control unit sends a "pause playback" command to the TV via Bluetooth. The TV pauses playback and displays a prompt interface saying, "Please complete the remote control unlocking action to resume playback." The user completes a preset simple action (such as shaking the remote control up and down 3 times, or drawing circles 2 times) or a combination of button actions (such as alternatingly pressing "volume +" and "volume -" 2 times). After the accelerometer collects and verifies the action data, unlocking and recovery are performed. The remote control sends a "resume playback" command to the TV, the TV resumes playback, the yellow LED indicator turns off, and a voice prompt says, "Unlock successful, enjoy your viewing." If unlocking is not completed within 3 minutes, the TV remains paused, with the reminder repeated every 30 seconds.

[0072] Optionally, in response to the user's triggering operation on the preset function key on the remote control, the eye protection interactive function is executed, including: in response to the user's pressing of the eye protection interactive key, sending a start command to the TV eye protection program to turn on the TV camera and prompting the user that the eye protection mode has been started; acquiring the user's blink data captured by the TV camera; and controlling the TV to pop up the eye protection interactive interface when the user's blink data shows that eye protection intervention is needed.

[0073] In this embodiment, after the user presses the eye protection interaction button, a series of complex operations can be automatically executed, including starting the TV eye protection program, turning on the camera, acquiring blink data, and determining and triggering the intervention interface. The eye protection intervention decision is based on the user's real-time physiological indicators, such as blink frequency, rather than fixed time or simple environmental parameters, enabling proactive and precise intervention even before the user is aware of discomfort. After the eye protection interaction interface pops up, the user needs to complete relief activities according to the interactive tasks, effectively interrupting continuous eye use behaviors that may lead to eye fatigue.

[0074] In one specific embodiment, the remote control receives a "eye protection interaction button" press command and sends a "start eye protection program" command to the TV via Bluetooth. The TV camera turns on, and a voice prompt says, "Eye protection mode is activated, please look directly at the screen." The TV camera captures the user's facial image and extracts blink frequency data (sampling time 3 seconds). If a blink frequency of less than 15 times / minute (eye fatigue signal) is detected, the TV sends a "intervention required" command to the remote control. The remote control starts a gentle vibration (lasting 2 seconds), and a voice prompt says, "Please relax your eyes and complete a simple interaction." The TV displays an interactive task interface (such as "blink slowly 3 times" or "shake your head gently 1 time"). After the user completes the task, the TV returns to normal display, and the green indicator light on the remote control stays on. If the user does not respond within 30 seconds, the remote control vibrates repeatedly to remind the user, and the TV continues to display the interactive task until it is completed.

[0075] Optionally, in response to the user's triggering operation on the preset function key on the remote control, the eye protection interactive function is executed, which further includes: in response to the user pressing the eye protection interactive key, collecting the user's heart rate data; and when the user's heart rate data shows that eye protection intervention is required, controlling the TV to pop up the eye protection interactive interface.

[0076] In this embodiment, the blink detection function of the TV camera is replaced by a heart rate sensor built into the remote control. The heart rate sensor collects the heart rate data of the elderly. When the heart rate is >80 beats / minute (which may be accompanied by fatigue), an eye-protection interactive task is triggered. This eliminates the need for a TV camera and is compatible with older TVs that do not have a camera.

[0077] Optionally, after the user presses the eye protection interaction button, the system also includes switching the TV to a preset eye protection mode. The preset eye protection modes include: gentle mode and reading mode.

[0078] Optionally, in response to the user's triggering operation on the preset function key on the remote control, the emergency call function is executed, including: in response to the user's operation of pressing and holding the emergency call key, controlling the remote control to provide an audio and visual alert; controlling the TV to pop up a warning pop-up window and sending an emergency help message to the bound mobile APP; the emergency help message includes real-time location data and preset help text; collecting the current ambient sound and transmitting the current ambient sound to the bound mobile APP.

[0079] In this embodiment, after the user presses and holds the emergency call button, a series of actions are automatically triggered in parallel: local audio-visual alerts on the remote control, a pop-up warning on the TV, and sending a distress message to the linked mobile app. This multi-device synchronous response ensures that the distress message can be transmitted quickly and reliably through multiple channels, minimizing information delays caused by single device or communication problems and saving valuable time for rapid rescue. By transmitting real-time location data and current ambient sound, it provides multi-dimensional on-site information far exceeding that of a simple text-based distress call, enhancing the accuracy of rescue efforts and on-site judgment.

[0080] In one specific embodiment, after the main control unit detects a long press signal on the SOS button, the red LED indicator flashes rapidly, the vibration module activates enhanced vibration (lasting 3 seconds), and a voice prompt says, "Emergency help has been sent, please wait for a response." The Bluetooth module sends an "Emergency Help" command to the TV, and the TV pops up a red warning window (displaying "Emergency Help in progress"). Simultaneously, a help message is sent to the linked mobile app, including real-time location data and a preset help message (such as "I need help, please contact me as soon as possible"). Furthermore, the microphone activates, collecting real-time ambient sound from the home and transmitting it to the mobile app via Bluetooth, allowing family members to listen in real-time. Transmission continues until the user presses the SOS button to cancel or the family member closes the app. The user can also cancel the help request by pressing the SOS button again for 1 second; the red LED indicator turns off, a voice prompt says "Help request canceled," the TV pop-up closes, and the mobile app sends a "Help request cancelled" notification. Additionally, the remote control can have a built-in micro SIM card, allowing direct dialing of preset emergency contacts (such as children or community service centers) after pressing the SOS button, while simultaneously sending a location-based SMS message, suitable for elderly people who do not use smartphones. In case of emergency, ambient temperature data can be transmitted simultaneously. If the temperature is abnormal (e.g., >35℃ or <5℃), a temperature warning will be sent to the family to help assess the situation on site.

[0081] Optionally, the method for controlling the remote control further includes: when the user sends a remote control search command through the bound mobile APP, responding to the remote control search command by controlling the remote control to provide an audio and visual alert; and sending a Bluetooth signal to the bound mobile APP to display the distance information between the remote control and the mobile phone on the bound mobile APP.

[0082] Combination Figure 4 As shown, this disclosure provides another method for controlling a remote control, including: S401, the processor collects the distance signal between the user and the TV, the ambient light intensity signal, and the acceleration signal of the remote control.

[0083] The S402 processor generates instructions for adjusting the TV's display parameters based on distance and light intensity signals.

[0084] S403, the processor determines whether the user is in a sedentary state based on the acceleration signal, and executes the sedentary intervention process if the user is in a sedentary state.

[0085] S404, the processor responds to the user's trigger operation on the preset function key on the remote control and executes the corresponding health protection function; the health protection function includes eye protection interactive function and emergency call function.

[0086] S405: When the user sends a remote control search command via the bound mobile APP, the processor responds to the remote control search command by controlling the remote control to provide sound and light alerts and sending a Bluetooth signal to the bound mobile APP to display the distance information between the remote control and the mobile phone on the bound mobile APP.

[0087] In this embodiment, in the event of a lost remote control, the remote control location function can be remotely and actively triggered. The remote control can be controlled to provide local audio-visual alerts (such as flashing indicator lights, vibration, and a voice announcement saying "I'm here") via a search command. This provides the most direct and effective location clues within close proximity and line of sight, allowing users to quickly locate the device by following sound or light. Sending Bluetooth signal strength to the linked mobile app displays distance information (such as "≤3 meters"), providing macroscopic and directional guidance in larger spaces, helping users quickly determine the approximate location and narrow down the search area.

[0088] In one specific embodiment, the user or family member clicks "Find Remote Control" on the mobile app to send a location command to the remote control; after receiving the command, the remote control flashes a green LED indicator light rapidly, starts a gentle vibration (lasting 5 seconds, repeated every 3 seconds), and provides a voice prompt "I am here," making it easier for the elderly to find the remote control by sound and light; the mobile app displays the approximate distance between the remote control and the mobile phone based on the Bluetooth signal strength (e.g., "Distance ≤ 3 meters", "Distance 3 to 5 meters", "Distance > 5 meters") to assist in quick location.

[0089] Optionally, the method for controlling the remote control further includes: sending health data to the bound mobile app based on a preset period; the health data includes viewing time, number of sedentary interventions, number of times the eye protection interactive function is activated, and the completion status of the TV unlocking action; and / or, monitoring the battery level of the remote control, triggering a low battery reminder when the battery level is lower than a preset value, and sending a low battery notification to the bound mobile app.

[0090] In this embodiment, by viewing personal health data collected by the remote control, it is possible to objectively and quantitatively understand the user's movie-watching habits, sedentary frequency, and compliance with health tips. This helps identify unhealthy habit patterns and provides data support for encouragement, reminders, or adjustments to intervention parameters, thereby assisting users in developing healthier movie-watching habits. Corresponding data reports can also be generated based on the health data. These intuitive reports enhance users' awareness of their own behavior and health consciousness. Other family members can easily understand the user's daily life status and health trends, enabling remote communication or reminders when necessary, thus strengthening connections and a sense of security among family members. By monitoring battery power, users are given ample buffer time to charge the remote control, preventing movie-watching interruptions due to sudden power loss and the inability to use the emergency call function in emergencies. This ensures the continuous availability of core health protection functions, improving product reliability and user satisfaction.

[0091] In one specific embodiment, the main control unit synchronizes data to the mobile APP every 30 minutes, including viewing time, number of sedentary interventions, number of times eye protection mode is activated, and unlocking action completion status. The mobile APP generates a health report for users and their families to view, helping to develop reasonable viewing habits.

[0092] In one specific embodiment, the power management module monitors the battery level in real time. When the remaining power is ≤20%, a low power reminder is triggered: the green LED indicator turns yellow and flashes, a voice prompt says "Battery is low, please charge in time", and a low power notification is sent to the mobile APP.

[0093] The following describes the method for controlling a remote control provided in the embodiments of this disclosure using some specific application scenarios.

[0094] In scenarios where elderly people live alone and watch movies, the remote control monitors distance and light in real time, automatically adjusting TV display parameters. It also provides reminders to move around when sitting for extended periods and can quickly trigger an SOS for help in emergencies, allowing family members to monitor the situation via a mobile app. For elderly people with poor eyesight, large buttons, clear voice prompts, and vibration feedback help them quickly identify buttons and confirm operations, allowing for normal use without relying on their eyesight. For elderly people with limited mobility, simple unlocking actions (shaking, circling) replace getting up, and eye protection and emergency functions are triggered with a single button, reducing difficulties caused by mobility issues. In elderly care facilities, the remote control is compatible with public TVs and can be linked to a nursing station's mobile app. When an elderly person presses the SOS button, the nursing station receives the help request and location information in real time, providing rapid service. In community service scenarios, it connects with community health service centers, allowing health data to be synchronized to community health records. This helps community staff understand the elderly's movie-watching habits and provide targeted health guidance. For elderly people with disabilities, the unlocking action is replaced with button combinations or voice commands, further reducing operational difficulty and meeting special needs.

[0095] The method for controlling a remote control provided in this disclosure constructs a multi-dimensional intelligent eye protection system, realizing scientific intervention for prolonged sitting, strengthening emergency protection and anti-loss capabilities, and optimizing elderly-friendly interactive design. By using distance and light sensors to adapt to TV display parameters in real time, combined with camera blink monitoring and interactive task unlocking mechanisms, it achieves full-process eye protection through "environmental adaptation + physiological monitoring + proactive intervention," reducing the risk of eye fatigue in the elderly, with no complicated settings required. Based on an accelerometer to accurately identify prolonged sitting, it establishes a tiered intervention mechanism of "vibration reminder - TV pause - simple action unlock," linking with a mobile health app to record data, helping the elderly develop reasonable viewing habits and reducing the health risks of prolonged sitting. A convenient SOS emergency call function is added, enabling multi-terminal linkage through TV pop-ups, mobile phone location + help information + environmental sound transmission, coupled with low battery warning and location functions, improving the safety of elderly people living alone and preventing remote control loss. The operation logic is simplified, with core functions triggered with one click, using gentle vibration and clear prompts; the unlocking action is simple and easy to execute, adapting to the cognitive and operational abilities of the elderly, and lowering the barrier to use.
