Project Background

Baji (badge-style trendy toys) sell over 800 million units yearly but only serve as static collectibles. Gen Z craves immersive IP experiences. With low-cost NFC tech available, the market lacks portable interactive devices for Baji. This project uses AI to recognize NFC chips, match IP-specific audio effects, enabling “one Baji, one exclusive interaction”—filling the gap for smart interactions in small trendy toys.

Design Process of "Baji Bubble" AI Interactive Terminal

Requirement Analysis and Positioning Stage: Combine market research (interactive needs of trendy toy users, NFC technology application cases) and target user portraits (Gen Z Baji collectors) to clarify the core functions—NFC identification + AI sound effect matching. Determine the “portable lanyard-type” form of the product, output the “Requirement Specification”, and define key indicators such as AI sound effect library capacity and recognition response speed (≤0.5 seconds).
Hardware Scheme Design Stage: Select NFC identification modules (prioritizing low-cost, small-size models), microcontrollers (such as STM32 series), audio output units (micro speakers + noise reduction chips) and power modules (button batteries/rechargeable lithium batteries). Complete the drawing of hardware circuit schematics and PCB board design, simultaneously determine the terminal shell material (ABS environmentally friendly plastic) and size (diameter ≤5cm), and output the “Hardware Design Scheme”.
AI Sound Effect System Development Stage: Build an AI sound effect matching algorithm model, train the system to recognize the corresponding relationship between NFC chip IDs and IP sound effects; collaborate with IP parties to collect/produce exclusive sound effects (character lines, BGM clips, etc.), construct a sound effect database and optimize storage logic; develop a “sound effect update interface” to support users in uploading custom sound effects through the mobile APP, and output the “AI Sound Effect System Development Document”.

Software and Firmware Development Stage: Write hardware driver programs (NFC identification driver, audio playback driver) and main control programs to realize the complete process of “NFC induction – AI matching – sound effect output”; develop a supporting mobile APP (supporting Bluetooth connection for sound effect management and device settings), complete the joint debugging of software and hardware to ensure a recognition accuracy rate of ≥98%, and output the “Software and Firmware Development Report”.
Appearance and Structure Design Stage: Design the terminal shell in line with trendy toy aesthetics (optional IP co-branded pattern customization), optimize the lanyard interface structure to ensure portability; conduct structural simulation tests (anti-drop, waterproof grade IP54), adjust the shell curvature to improve grip feel, and output 3D modeling diagrams and prototype samples.
Prototype Testing and Iteration Stage: Produce 100 functional prototypes, invite target users to conduct actual tests, and collect feedback such as “recognition sensitivity, sound effect clarity, appearance satisfaction”; carry out iterative optimization for problems (such as enhancing NFC induction distance, adjusting speaker volume), complete 2-3 rounds of prototype iteration, and output the “Prototype Testing Report”.
Mass Production Preparation and Implementation Stage: Determine the mass production factory, complete mold development and supply chain stock preparation; formulate production quality control standards (such as 100% functional testing for each device), simultaneously complete product packaging design (including user manual, IP stickers), and finally realize mass production and market launch.
