The system generates healing feedback after fusing multi-modal data, automatically controls light brightness, color change, fragrance and negative oxygen ion release and voice and character pacifying guide content, and realizes body and mind regulation and emotion healing. The system is suitable for scenes such as meditation guiding, emotion relieving and sleep assisting, and has the characteristics of active perception, personalized response, visual / olfactory / auditory linkage output and the like.

Description

[0001] The present invention relates to the fields of intelligent hardware and health treatment equipment, and in particular to an intelligent interactive lighting system that combines physiological data detection, emotional state recognition and multimodal treatment feedback, belonging to the technical field of intelligent emotion regulation devices. Background Art

[0002] As the pace of cities accelerates and social pressure increases, more and more users are experiencing emotional problems such as anxiety, insomnia, and mental tension. Although there are some atmosphere lights, aromatherapy equipment, and breathing light products for relaxation on the market, their functions are mostly static lighting or basic rhythm control. They cannot achieve active interaction with the user's physiological state, nor can they dynamically respond and provide healing guidance based on the user's real-time emotional state. At the same time, existing emotion regulation devices generally lack the ability to perceive and analyze the user's individual emotional characteristics, and cannot meet the personalized emotion regulation needs of different users. The healing effect is limited and user stickiness is low. Therefore, there is an urgent need for an emotional healing interaction system that actively identifies the user's physiological state and can link multiple sensory output forms to achieve a deeper and more accurate body and mind adjustment experience. Summary of the invention

[0003] The purpose of this invention is to provide an intelligent interactive lighting system based on pulse sensing and comprehensive feedback of light, smell and sound, which can perceive the user's emotional state in real time and provide targeted emotional guidance and physical and mental healing to the user through multimodal output forms such as light, fragrance, negative oxygen ions, voice or text.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: The intelligent healing lamp system includes: • Touch sensing module to initiate user interaction; • Pulse detection module, used to collect the user's fingertip pulse signal; • Emotion recognition processing module, including: • Pulse signal analysis submodule based on heart rate variability (HRV); • Optional emotion judgment submodule based on facial expression image recognition; • Lighting control module, used to adjust the light color and brightness according to emotional state and generate breathing rhythm change curve; • Fragrance and negative oxygen ion release module, which releases corresponding natural fragrance and negative oxygen ions according to the recognition results; • Voice or text prompt module, used to output short healing phrases or soothing guidance words that match the emotional state; • The control system is used to coordinate the above modules, complete the entire healing process, and turn the lights to warm white and terminate the guidance output after the emotions are stabilized.

[0005] Furthermore: The above-mentioned emotion recognition processing module can improve the recognition accuracy and personalized feedback ability through bimodal data fusion (physiological + visual). Description of the Drawings Figure 1 It is a schematic diagram of the system structure It shows the overall structural layout of the emotion healing lamp described in the present invention, including: · Lighting module: used to output color light effects that change with emotions; · Touch sensing module: used to detect the user's hand touch behavior and trigger the interaction process; · Pulse detection module: obtains the user's pulse data through a PPG optoelectronic sensor; · Emotion recognition module: includes a sub-module based on HRV analysis and an optional facial expression recognition sub-module; · Lighting control module: controls the light brightness, color, and rhythm according to the emotional state; · Aroma and negative ion release module: sprays aromas and negative ions that match the emotions; · Voice or text guidance module: plays emotion healing statements or soothing guidance; · Control center: responsible for coordinating the above modules and executing the healing process. Each module is connected through control signals and data paths to form a complete intelligent interactive emotion healing system. Figure 2 It is the functional flow logic This is the functional module logic diagram of the system of the present invention, which describes the signal flow and processing steps from user trigger to output of the healing result, specifically including: 1. User touch input: The user touches the lamp to start the interaction process; 2. Pulse sensor: Collects the user's pulse data (HRV analysis); 3. Optional facial recognition: The camera collects the user's facial expression features; 4. Emotion analysis engine: Fuses HRV data and facial data for emotion recognition; 5. Lighting feedback controller: Generates emotion light feedback; 6. Aroma, negative ion, controller: Releases aroma + negative ions adapted to emotions; 7. Voice / text output module: Outputs guiding statements; 8. Final healing output: Synchronously outputs light, smell, sound / words to construct a complete healing experience. Figure 3 It is the emotion recognition flow chart · [Touch activation]: It means that the user touches the surface of the lamp and the system starts the emotion detection process. [Pulse Data Collection]: Read pulse wave signals through PPG (photoplethysmography) sensors. [Facial Image Collection (Optional)]: If the user allows, collect their facial image for emotion-assisted recognition. [HRV Calculation]: Analyze heart rate variability based on pulse signals and infer emotional state. [Facial Emotion Analysis]: Analyze emotional characteristics through facial feature extraction algorithms. Data Fusion Engine: Fusion HRV and facial analysis results to improve emotion recognition accuracy. Emotion Recognition Results: The final classification result of the user's current emotional state is obtained. Figure 4 The rhythm curve of light breathing The natural rhythm of light brightness changing over time: Inhale (light gradually increases) Exhale (light gradually decreases) Complete a full breathing cycle every 12 seconds, guiding breathing therapy Figure 5 A diagram showing the return of light after emotional healing is completed. After the emotional healing process is complete, the light will gently transition from highly saturated emotional colors (such as purple and blue) to warm white. This process lasts approximately 20 seconds, reflecting the transition from emotional feedback to a calm and relaxed state. During this period, the light intensity gradually decreases in color saturation, eventually stabilizing at a soft, soothing warm white.
