PROBLEM TO BE SOLVED: To provide the computerized method and device for interacting with an object in a scene which can be observed through a camera. SOLUTION: The active open user interface of a computerized kiosk 50 visually senses a human by using motion and colors to detect changes in the environment wherein the human is present. Interaction spaces 75 and 80 are defined and the system records an initial model for the environment updated with time so that the addition or subtraction of nonliving bodies is reflected and variation in lightness is compensated. The system develops a model for the object and can therefore trace the human who is moving in the interaction spaces 75 and 80. Further, a stereoscopic camera system improves the capability of the system sending the position and motion. The kiosk provides vocal and visual feedback as an answer to its 'seeing'.
