<p>A computer system (200-322) stereoscopically projects a three dimensional object (245) having an interface image (250) in a space observable by a user (100). The user controls the movement of a physical object (400) within the space while observing both the three dimensionally projected object and the physical object. The computer system monitors the position of the user to determine the position of the interface image within the space and further monitors the movement of the physical object to determine its position. A control signal is generated in response to the position of the physical object intersecting the position of the interface image. For example, a word processing program is indicated by an interface image such as an icon including the letter "W" three dimensionally projected within the space. The word processing is activated when the user's finger moves within the space to touch the projected icon.</p> |
