Solution Overview
Problem
Existing methods for presenting context information are limited to fixed presentation in either the real space or mirror image space, lacking flexibility and freedom in choosing the presentation space.
Innovation Solution
An aerial image display system utilizing a retroreflective member and optical members with a display device that can move between real and mirror image spaces and adjust its display direction, allowing seamless formation of aerial images across the boundary between these spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information is fixedly presented in either real space or mirror image space, then the presentation method is simple, but the degree of freedom in information presentation is limited
Solution Approach 1:
The display device is made movable between real space and mirror image space through a movement mechanism unit, and its display direction is made adjustable through a rotation mechanism unit. This dynamic configuration allows the system to switch between different presentation modes (real space display, mirror image space display, direct view) thereby achieving high adaptability in information presentation without permanently complicating the optical system structure
Solution Approach 2:
The display device serves multiple functions by being positioned in different spaces and orientations. The same display device can present information in real space, mirror image space, or directly to the viewer, making the system universal and versatile without requiring separate dedicated devices for each function
2Adaptability or versatility
If the display device is movable and rotatable, then the degree of freedom in information presentation is improved, but the device complexity increases
Solution Approach 1:
The complex functions of moving and rotating the display device are segmented into two independent mechanism units: a movement mechanism unit for position control and a rotation mechanism unit for orientation control. This segmentation allows each unit to be optimized independently and simplifies the overall control system while maintaining full flexibility in display position and direction

AI summary
In one aspect of the present invention, a retroreflective member is arranged in a state where a reflective surface is orthogonal or near-orthogonal to a viewing direction of a viewer. A first optical member is arranged between the viewer and the retroreflective member in a state where an action surface is parallel or near-parallel to the reflective surface of the retroreflective member, a mirror image space is formed between the first optical member and the retroreflective member, and a real space is formed in a space where the viewer is present. A second optical member is arranged in the mirror image space in a state where an action surface is inclined at a predetermined angle with respect to the viewing direction, and a mirror image space movement region is formed between the second optical member and the retroreflective member.
