Wearable Language Tutor (Embedded System)
Summary
A hands-on wearable embedded system designed to deliver interactive language lessons while operating within power, storage, and hardware constraints.
Problem / Goal
The goal was to build a portable device capable of delivering structured language lessons without relying on a constant network connection. The system needed to be lightweight, responsive, and reliable for repeated daily use.
What I Built...
I designed and implemented a wearable embedded system using an ESP32-based platform with a touchscreen interface and SD card storage. The device loads lessons locally from structured data files, presents interactive content through a simple UI, and manages user interaction without external dependencies.
Constraints and Design Decisions
Because the device operates on limited memory and power, lesson data was stored locally in efficient formats and loaded dynamically rather than kept in memory. UI elements were intentionally kept lightweight to maintain responsiveness, and system logic was structured to support reliability over visual complexity.
What This Demonstrates
- Embedded systems development on ESP32-class hardware
- Touchscreen UI integration for constrained devices
- Local data storage and retrieval under memory limitations
- System design focused on reliability and repeatable operation
- Practical debugging and iteration on real hardware
