Problem Statement: While music is essential for child development, modern interaction often happens via touchscreens, which lack tactile feedback and fine motor skill training. "Tangible User Interfaces" (TUIs)—where physical objects control digital data—offer a more developmentally appropriate way for children to interact with technology, yet designing robust, child-safe TUIs requires solving complex challenges in hardware integration and interaction logic.
Project Goal: The goal is to design and develop a Tangible Music Interface. Instead of screens, the system should use physical artifacts (e.g., RFID-tagged figurines, color sensors, or conductive objects) to control sound. The prototype must integrate hardware sensors with a robust software state machine to create an engaging, educational experience.
Core Tasks:
- Interaction Design: Define a physical interaction concept appropriate for a specific age group (e.g., "Placing a block = Play a specific instrument" or "Stacking blocks = Mixing tracks").
- Hardware Integration: Build the physical prototype using microcontrollers (Arduino/ESP32 or Raspberry Pi). Integrate sensors (e.g., RFID/NFC, Accelerometers, or Capacitive Touch) and audio output modules (e.g., DFPlayer Mini or I2S DAC).
- Software Logic (Gamification): Implement the core logic. To ensure sufficient software complexity, the system must include an interactive mode (e.g., a "Simon Says" memory game, a sequence recorder, or a quiz mode) rather than just passive playback.
- Enclosure Engineering: Design and construct a robust, user-friendly housing. Note: Safety and durability are key requirements for child-focused hardware.
Research Focus:
The research focus lies on a Usability & Design Evaluation.
Option A (User Study): Observe a small group of users interacting with the device to measure engagement and intuitiveness.
Option B (Heuristic Eval): Rigorously evaluate the prototype against established Child-Computer Interaction (CCI) guidelines.
