Description

TECHNICAL FIELD

[0001] The present application relates to the field of human-computer interaction and intelligent device technology, and in particular to a smart interaction system and method for triggering customizable audio feedback through the plugging and unplugging of physical cards. The system creatively establishes a dynamic mapping relationship between physical card operations and digital audio content, enabling multi-scene applications from daily life management to creative entertainment. BACKGROUND

[0002] Current human-computer interaction systems have obvious functional limitations: practical tools generally lack emotional interaction experience, while entertainment devices often deviate from real-life scenarios. Traditional card storage devices only provide physical storage functions and cannot provide any intelligent feedback for user operations; existing audio playback devices mostly use fixed triggering methods (such as buttons, touch), lacking innovation in interacting with physical entities. More importantly, existing technologies have not proposed a general framework that allows users to freely define the mapping relationship between physical operations and digital feedback, resulting in limited interaction flexibility and difficulty in meeting diverse application needs. SUMMARY

[0003] The present application aims to break through the limitations of existing technologies and provide an innovative audio interaction system and method. The core of the system is to establish a completely customizable mapping framework that dynamically associates state change events of physical card slots with any digital audio content, thereby achieving a precise interaction experience of "one plug, one sound".

Provide a user configuration interface that supports multiple audio input methods such as local selection, real-time recording, or network upload b. Establish the association between card slot state events (insertion / removal) and audio files c. Store mapping configuration information in non-volatile memory to maintain configuration persistence State monitoring phase: a. Real-time monitoring of card status changes in each card slot b. Use a 10-50ms signal retention verification anti-shake algorithm to filter false trigger signals c. Generate standardized state event signals (including card slot ID and event type) Audio trigger phase: a. Analyze the state event and query the mapping relationship table to obtain the corresponding audio index b. Read the corresponding audio data from the memory c. Implement ordered playback of multiple events through audio queue management d. Support real-time audio processing and effect addition Advantages of the invention: Architectural innovation: Propose a complete "physical operation - digital feedback" mapping framework that is independent of specific hardware implementation, with high universality and scalability, solving the problem of lack of universal mapping architecture in existing technology Application diversity: Through different mapping configurations, the same hardware platform can implement multiple functions: ・Smart card box: Provide acoustic identification for various daily cards ・Music toy: Create personalized music through card combinations ・Educational tool: Make interactive learning devices ・Art device: Create immersive interactive experiences Natural interaction: Use the intuitive physical action of "inserting and removing cards" as the interaction method, reducing the use threshold and enhancing the naturalness and convenience of user experience Custom flexibility: Users can freely define mapping relationships through mobile applications, web interfaces, voice commands, and other methods, supporting instant updating and replacement of audio content Technical advancement: The use of non-contact detection technology improves system reliability and service life; supports multiple audio formats and real-time processing, ensuring sound quality and response speed BRIEF DESCRIPTION OF DRAWINGS

[0009] The embodiments of the present application are described in detail below with reference to the accompanying drawings: The core of the system is the implementation of the mapping management module. This module maintains a dynamic mapping table, which records the correspondence between the two state events (insertion / removal) of each slot and the specific audio file. Users can configure the mapping table in the following ways: Mobile application configuration: Select audio from the local music library or record new audio directly through a dedicated APP, and associate it with the virtual card slot through drag-and-drop operation Web interface configuration: The system provides a Web configuration interface, and users can upload audio files and set mapping relationships through a browser Voice configuration: Supports quickly setting common audio mappings through voice commands Automatic configuration: The system can automatically match the pre-set audio file according to the characteristics of the inserted card (such as RFID identification) In terms of audio processing, the system supports a variety of enhancement functions: · Audio effect processing: Add effects such as reverb, equalization, voice change, etc. to the played audio · Sequence playback: Supports combining multiple audio files into a playback sequence · Intelligent response: Automatically adjust parameters such as volume, playback mode, etc. according to the use scenario Example 1: Use as a smart card box Users put their work card, access card, and transportation card into different card slots, and set different prompt sounds for each card slot through the mobile phone APP. When the work card is taken out, the system plays the "work happily" voice prompt; when the access card is inserted, the "safe access" prompt sound is played. In actual application, the mis-triggering rate of this mode is ≤0.1 times / day, meeting the daily use requirements. Example 2: Use as a music creation tool Users map five special cards to different instrument timbres (piano, guitar, drum, bass, string), create music fragments by plugging in card combinations. The system supports 16-track audio parallel processing, records operation sequence and rhythm, and generates complete music works. Example 3: As an educational tool Teachers associate different learning cards (letters, numbers, words) with corresponding pronunciations, and students interactively learn by plugging in cards. The system provides instant voice feedback. This mode supports speed adjustment and repeat playback functions, and adapts to different learning progress needs.
