Gesture-Controlled Presentation and Annotation
A touch-free presentation tool that lets a speaker move through slides, point, annotate and undo using deliberate hand gestures.
Let a speaker stay engaged with the material while controlling the presentation.
Moving between a lectern, keyboard and display can interrupt an explanation. This presentation tool uses deliberate hand interaction for slide navigation, pointing and annotation, helping a speaker demonstrate ideas without continuously returning to a controller.

The user experience
The presenter navigates slides, highlights an area or adds a drawing, then undoes or clears marks as the explanation develops. Keyboard fallback and camera feedback support a practical supervised presentation setup.
Practical value
Supports a more fluid interaction style, with exported presentation images useful for retaining the annotated explanation.
