We describe how to build a VIDEOPLACE-like vision-driven user interface using "optical-flow" measurements. The optical-flow denotes the estimated movement of an image patch between two consecutive frames from a video sequence. Similar framework is used in a number of commercial visiondriven interactive computer games but the motion of the users is detected by examining the difference between two consecutive frames. The optical-flow presents a natural extension. We show here how the optical-flow can be used to provide much richer interaction.
