USER INTERFACE DISPLAY DEVICE

摘要

An optical panel having an image-forming function is disposed in parallel with a virtual horizontal plane so that the optical axis thereof is orthogonal to the virtual horizontal plane. A flat panel display is disposed in offset relation below the optical panel such that a display surface of the flat panel display is inclined at a predetermined angle with respect to the virtual horizontal plane and faces upward. A light source for projecting light toward a hand, and a camera for imaging the reflection of the light from the hand are provided below or above a spatial image image-formed above the optical panel. This provides a user interface display device which does not include structure serving as an obstacle to manipulation around the spatial image projected in space to achieve an interaction with the spatial image by using the hand of the operator in a natural manner.

主权项

1. A user interface display device for interactively controlling a video picture in association with the motion of a hand, comprising:
a flat panel display including a display surface; an optical panel; a light source for projecting light toward the hand; and an optical imaging means for imaging the reflection of the light from the hand; wherein a video picture appearing on the display surface of the flat panel display is image-formed in a spatial position spaced a predetermined distance apart from the flat panel display by means of the optical panel, wherein the optical panel is disposed in parallel with a virtual horizontal plane based on an operator, so that the optical axis of the optical panel is orthogonal to the virtual horizontal plane, wherein the flat panel display is disposed in an offset relation below the optical panel in such an attitude that the display surface is inclined at a predetermined angle with respect to the virtual horizontal plane and is positioned to face upward, and wherein the light source and the optical imaging means are provided in a pair below or above the spatial position at which the video picture is image-formed above the optical panel.
