Abstract: An interactive control system for an image display device includes a case with an opening, a luminous source image display, a focusing element, and an interactive device. The luminous source image display displays a first image and the source image display is positioned within the case. The focusing element receives light and focuses the light to form a second image that is viewable through the opening, and the focusing element is positioned within the case. The interactive device controls the behavior of the system in response of input from a user. The interactive device includes a sensor system which detects a motion of the user. The focusing element includes a concave mirror with a black coating on the reflecting surface. The sensor system detects three-dimensionally a location and motion of a given object in a space in the opening of the case in front of the focusing element.

Abstract: An olfactory advertising system combined with image display device includes a case, a luminous source image display displaying a first image, a focusing element receiving light from the source image display and focusing the light to form a second image that is viewable through the opening of the case, an interactive devices for controlling the behavior of the system, and a scent generating device. The scent generating device releases a predetermined scent according to the electronic signal from the interactive devices. The focusing element includes a concave mirror with a black coating on the reflecting surface. The scent generating device comprises a sensor system, and the sensor system detects a motion in a sensitive space in the opening of the case in front of the focusing element and produces an electronic signal.

Abstract: An image display device includes a case having an opening, a luminous source image display displaying a first image, a focusing element receiving light from the source image display and focusing the light to form a second image that is viewable through the opening of the case, and an image source providing image information to the source image display so that the source image display displays the first image. The focusing element has a concave mirror and a mirror supporter that supports the concave mirror. The perimeter of the concave mirror has at least one straight-cut portion that has a line contact with the mirror supporter. The image information provided by the image source is changed with user interaction.
