Abstract
An information display system includes a frame, a pair of cameras arranged at both side ends of the frame, a transparent display fitted into the frame, a display position setting device that detects a target based on a feature extracted from image data captured by the pair of cameras, and sets, as a display position, a position at which a straight line connecting an eye of a user wearing the frame and the target passes through the transparent display, and a controller that controls the transparent display in such a way as to display a point light at the display position set by the display position setting device.
