Explore the secrets of Touchless Gesture - Controlled Smart Interface ( Hand - Tracking ESP32 OLED... with us, and benefit from the valuable insights it provides regarding gesture.
Touchless Gesture-Controlled Smart Interface (Hand-Tracking + ESP32 + OLED)
I recently completed a Touchless User Interface project that uses hand-gesture recognition with MediaPipe + OpenCV and communicates with an ESP32-based OLED display to create a fully hands-free menu navigation system.
Tech Stack
- Python (OpenCV, MediaPipe)
- ESP32 (Arduino IDE)
- SSD1306 OLED Display over IC
- Serial Communication between PC and ESP32
Features:
Real-time hand tracking with index finger and pinch-click detection.
Hover-based selection with timeout.
Touchless interactive menu including:
- Home
- Start
- Payment
- Balance
- Intro
- Back navigation
Synchronized UI on both webcam interface and OLED screen.
Centered headers, responsive panel design, and smart button spacing.
Full Source Code (Python + ESP32 + OLED UI)
Applications:
- Kiosk systems
- Touchless ATMs
- Smart public terminals
- Hygiene-critical environments (Healthcare, Labs, Restaurants)
This project helped me improve in:
Human–Computer Interaction
Embedded Systems
UI/UX for hardware interfaces
Python–microcontroller integration
IC communication
Happy to share more details or code if anyone is interested!
