The Multifunctional PC Partner Based on ESP32 and LVGL is a self‑built hardware‑plus‑firmware solution that reimagines everyday computer input by fusing an airborne gyroscope mouse with fully customisable hot‑keys—all in a pocket‑sized, ergonomically sculpted shell.

From July to October 2022 I designed the entire stack: selecting an ESP32 MCU and integrating a motion‑sensor array for sub‑pixel gesture tracking; coding a slick, LVGL‑powered on‑device UI and firmware algorithms that smooth raw gyro data into fluid pointer motion; and implementing low‑latency Bluetooth/USB connectivity with cross‑platform drivers. Multiple test‑and‑refine cycles with real users sharpened accuracy and comfort, culminating in a portable companion device that showcases end‑to‑end embedded engineering, intuitive HCI design, and a keen sensitivity to user workflow pain‑points.
