Abstract: This invention comprises a method and system for displaying free-space, full color, high-resolution video or still images while simultaneously enabling the user to have real-time direct interaction with the visual images. The system comprises a self-generating means for creating a dynamic, non-solid particle cloud by ejecting atomized condensate present in the surrounding air, in a controlled fashion, into an invisible particle cloud. A projection system consisting of an image generating means and projection optics, projects an image onto the particle cloud. Any physical intrusion, occurring spatially within the image region, is captured by a detection system and the intrusion information is used to enable real-time user interaction in updating the image. This input/output (I/O) interface provides a display and computer link, permitting the user to select, translate and manipulate free-space floating visual information beyond the physical constraints of the device creating the image.

Abstract: This invention comprises a method and apparatus for displaying full color, high resolution dynamically generated real images and allowing the user to have direct interaction with the image. This input/output device provides an intuitive computer/video interface that permits the operator to grab, translate and manipulate a real image. The apparatus comprises a pair of coaxially positioned parabolic mirrors and a video imaging device allowing for 360 degree viewing. The real image, that appears floating within the opening of a viewport, is completely interactive by means of a detection system that tracks the operator, allowing the user to place his/her hand or finger through the image and engage it. Applications for this device are wide ranging, and include, for example, computer-aided design (CAD) and the entertainment/gaming industry by abandoning the conventional keyboard and mouse and allowing the user to have direct contact with the image.
