An obstruction is detected in the illumination field. The cursor position is determined as the point on the obstruction furthest from where the obstruction crosses a border of the illumination field.

Gestures are recognized as a function of movement of the obstruction and the determined distances."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interactive projection with gesture recognition","description":"An apparatus determines a cursor position in an illumination field of a projector.
