Technical Field
[0001] This invention relates to the field of AI interaction technology, and in particular to an AI-based smart home interactive control system. Background Technology
[0002] With the development of IoT and AI technologies, smart home systems are becoming increasingly popular. However, existing smart home systems have many problems in terms of interaction.
[0003] On the one hand, the interaction methods are relatively simple, relying heavily on user-initiated operations, and lack the ability to proactively perceive and adaptively adjust to changes in user behavior and environment;
[0004] For example, traditional lighting control often requires users to manually turn it on and off or switch through fixed scene modes, and cannot make intelligent adjustments based on the user's real-time location in the room, ambient light, and potential hazards.
[0005] On the other hand, their understanding and ability to handle complex scenarios are limited, making it difficult to comprehensively consider multiple factors to provide personalized services.
[0006] For example, in scenarios with frequent user activity or potential dangers, it may be impossible to accurately judge and adjust parameters such as light brightness and color in a timely manner to ensure user safety and comfort.
[0007] Therefore, there is an urgent need for an AI-based smart home interactive control system that can comprehensively perceive environmental and user information to achieve intelligent interaction, energy saving, and security. Summary of the Invention
[0008] The purpose of this invention is to propose an AI-based smart home interactive control system to solve the above-mentioned problems.

At the same time, it can intelligently turn on the appropriate lights according to the user's location and ambient light. It can also automatically adjust the light color according to the user's behavior and environmental needs in different rooms. For example, if the ambient light in the study is too cool, the light will be automatically adjusted to a warm yellow. At night, the bedroom lights will be adjusted according to the human body's biological clock, providing users with a personalized lighting experience that is both energy-saving and comfortable.

[0059] Brightness sensor: Real-time monitoring of ambient brightness; for example, during the day, if the brightness of the living room is higher than the set threshold (such as 500 lux), even if the user issues a command to turn on the lights, the system will combine other factors to determine whether it is really necessary to turn on the lights, so as to prevent unnecessary energy waste; in the evening, as the brightness gradually decreases, the sensor feeds the data back to the system to provide a basis for automatic lighting.
[0060] Human presence sensor: Using infrared or millimeter-wave radar technology, it accurately detects whether there is a person in the room; in the bedroom, after a person falls asleep at night, if no human activity is detected for a period of time (such as 30 minutes), the system automatically dims or turns off the lights to avoid the lights affecting sleep and save energy; when someone is detected entering the room, the lighting control system is immediately activated to prepare to respond to interactive commands;
[0061] Light color sensor: It senses the existing light color in the room to achieve adaptive adjustment of the light color; for example, in a study, if the ambient light is cool-toned, when the user turns on the light, the system automatically adjusts the light to a warm yellow, creating a comfortable reading atmosphere; in the bedroom, at night, according to the human body's biological clock, the light can be gradually adjusted from bright white light to soft warm light, which helps users relax and fall asleep.

[0064] The system collects users' voice commands through microphones in various areas of the room, converts the voice into text using a voice recognition algorithm, parses the text to understand the intent of the command, and executes the corresponding operation.
[0065] For example, when a user is busy in the kitchen with their hands covered in grease, they can say "Turn on the kitchen light." The voice recognition algorithm will convert the voice into text, then analyze the command intent to turn on the kitchen light. Personalized wake words can be set for different rooms, such as "Baby, turn on the light" in the children's room, to enhance the fun and sense of personalization.
[0066] Using cameras in various areas of the room, the system identifies user gestures based on computer vision technology and performs corresponding operations based on the identified gestures.
[0067] For example, when watching TV in the living room, users don't need to look for the remote control. They can simply make a fist and then open it in front of the camera, and the camera will recognize the gesture and turn on the living room chandelier. They can also adjust the brightness of the lights by waving their hands. For elderly people or users who are not familiar with operating smart devices, gesture interaction is simple and intuitive, lowering the barrier to entry.

[0075] It also obtains the ambient light intensity within the area covered by the cylindrical model, presets a light intensity threshold, and controls whether the predicted lights are turned on or off based on the comparison between the ambient light intensity within the area covered by the cylindrical model and the light intensity threshold.
[0076] If the ambient light intensity within the area covered by the cylindrical model is lower than the light intensity threshold, the predictive lights will be turned on; otherwise, the predictive lights will remain off.
