The Problem

Presenters have to stay near the keyboard or carry a clicker to move between slides.

The Solution

Uses MediaPipe hand-landmark detection on the webcam feed to recognize simple finger gestures and maps them to presentation keyboard shortcuts.

Key Capabilities
  • Real-time hand tracking from a normal laptop webcam, with no extra hardware.
  • Gestures for next slide, previous slide, start presentation, and exit presentation.
  • Works with Google Slides.
