Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked-eye three-dimensional image display apparatuses face challenges in providing a sufficient stereoscopic effect and reducing user burden due to high parallax, which can cause fatigue and sickness.
Innovation Solution
An information processing apparatus and method that controls the display of three-dimensional images by positioning the display surface at an angle to the horizontal plane, allowing a wider range of observation while minimizing parallax, using a display control unit to generate images based on user position and display surface geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the amount of parallax is increased to enhance the stereoscopic effect, then the three-dimensional perception is improved, but the user experiences fatigue and sickness due to difficulty in fusing images
Solution Approach 1:
The patent changes the orientation parameter of the display surface from horizontal to an angled position relative to the horizontal plane. This parameter change allows the system to achieve effective stereoscopic display while reducing the parallax amount that causes user discomfort, thereby resolving the contradiction between stereoscopic effect and user burden.
Solution Approach 2:
The patent introduces a new spatial dimension by angling the display surface rather than keeping it horizontal. This dimensional change creates a novel viewing geometry that maintains three-dimensional perception while minimizing the harmful parallax effects, thus solving the technical contradiction.
2Area of stationary object
If the display surface is positioned horizontally, then the observation area is limited, but positioning it at an angle reduces the observable area
Solution Approach 1:
By changing the orientation parameter of the display surface to an angled position, the patent expands the effective observation area while controlling the parallax within acceptable limits. This parameter optimization resolves the contradiction between maximizing observation area and maintaining viewing comfort.

AI summary
To provide an information processing apparatus, an information processing method, and a program for restraining a burden on a user who observes a three-dimensional image. Therefore, a display control unit performs display control to cause a three-dimensional image to be displayed so that a first plane surface parallel to a horizontal plane in a real space is observed in an area based on a distance between a lower end and an upper end of a display surface on which a display unit displays the three-dimensional image and an angle between the horizontal plane and the display surface.
