GestureFlow is a touch-free desktop utility that transforms any standard webcam into an application controller. By extracting 3D hand coordinates and using an optimized mathematical algorithm ($KNN$), the system maps natural hand signs to keyboard shortcuts in real time. It achieves a 96.4% accuracy rate with an unnoticeable latency of under 30 ms, running efficiently on standard laptop CPUs without needing expensive hardware.
Built on Python, the software runs silently in the background and features a customizable JSON backend so users can dynamically configure shortcuts for any application. While highly practical for presentation control, GestureFlow was deeply inspired by the developer’s recovery from bilateral shoulder surgeries, serving as a vital accessibility tool to eliminate the physical strain and mobility barriers of traditional mice and keyboards.
