Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image presenting devices, particularly head-mounted displays (HMDs), face challenges in enhancing the stereoscopic effect and reducing visual strangeness when presenting augmented reality (AR) images superimposed on real spaces, as the AR images often appear disjointed from real objects, lacking a harmonized and immersive experience.
Innovation Solution
A stereoscopic image presenting device and method that includes an image obtaining portion and an image presenting portion, capable of adjusting the position of virtual images based on depth information, using a combination of transmissive display sections and an optical element to generate and present virtual images in a way that aligns with real-world objects, thereby improving the stereoscopic effect and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AR images are superimposed on real space using conventional display methods, then the AR image can be presented to the user, but the AR image appears disjointed from real objects causing visual strangeness and reduced immersion
Solution Approach 1:
The patent transitions from conventional 2D display to volumetric 3D display by positioning multiple display sections at different depths along the optical axis. This creates a multi-layered display structure where images can be presented at different virtual distances, enabling true stereoscopic depth perception and harmonizing virtual objects with real space depth cues.
Solution Approach 2:
The display system is divided into multiple independent display sections (first, second, third display sections) positioned at different locations along the optical path. Each section can independently present images at different virtual distances, allowing selective positioning of AR content to match real object depths and improve stereoscopic realism.
2Reliability
If multiple display sections are positioned at different depths to improve stereoscopic effect, then the AR image harmonizes with real objects, but the device structure becomes more complex
Solution Approach 1:
The patent employs a single optical element (lens or mirror) that serves multiple functions: it receives light from multiple display sections positioned at different depths and forms virtual images of all sections at appropriate viewing distances. This multi-functional optical component consolidates what could otherwise require multiple complex optical systems.
Solution Approach 2:
Multiple display sections that could require separate optical paths are merged into a single integrated optical system. The display sections are positioned along a shared optical path, and a single optical element processes light from all sections simultaneously, combining multiple functions into one cohesive structure.

Function Achieved in This Case
The solution effectively enhances the stereoscopic effect by aligning virtual images with real objects, reducing visual strangeness and improving the overall immersive experience by dynamically adjusting the presentation position of virtual images based on depth information, leading to a more harmonized and realistic AR presentation.

AI summary
In a stereoscopic image presenting device 100, an image obtaining portion 102 obtains an image to be presented. An image presenting portion 104 presents a virtual image of the image obtained by the image obtaining portion 102 to a field of view of a user of the stereoscopic image presenting device 100. The image presenting portion 104 is configured to be able to change the position of the virtual image presented to the user, and changes the position at which the virtual image is presented on the basis of depth information of an object appearing in the image.
