Stereoscopic Display Control for Erroneous Fusion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic display techniques often result in user difficulty due to erroneous fusion issues, particularly when display objects are arranged side by side at equal intervals or at short presentation distances, leading to incorrect convergence angles and impaired stereoscopic viewing.
Innovation Solution
A display control device and method that includes an erroneous fusion determination unit to assess the display mode and presentation distance, applying a display effect to adjust the arrangement of display objects from an original mode to a second mode, such as an oblique or eccentric arrangement, to prevent erroneous fusion and ensure correct fusion at the intended convergence angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display objects are arranged side by side at equal intervals in the original display mode, then the display layout is simple and regular, but erroneous fusion occurs at short presentation distances leading to incorrect convergence angles
Solution Approach 1:
The patent applies asymmetry by changing the display mode from a symmetric equal-interval arrangement to an asymmetric arrangement where display objects are positioned at different intervals or with offset positions. This asymmetric positioning prevents the formation of incorrect convergence angles that cause erroneous fusion, while maintaining visual comfort and stereoscopic viewing reliability.
Solution Approach 2:
The patent applies local quality by adjusting the positioning of specific display objects individually rather than uniformly. Each display object's position is optimized based on its characteristics and the intended convergence angle, allowing different parts of the display to have different spatial properties that prevent erroneous fusion while maintaining overall display effectiveness.
2Ease of operation
If presentation distance is reduced to bring the image closer to the user, then viewing convenience is improved, but erroneous fusion occurs more frequently
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the positional parameters of display objects based on the presentation distance. When the presentation distance is short, the system modifies the arrangement parameters (positions and intervals) of display objects to prevent erroneous fusion, thereby maintaining stereoscopic viewing reliability while allowing close viewing distances for improved convenience.
3Measurement precision
If display objects are positioned to achieve correct fusion at intended convergence angle, then stereoscopic viewing accuracy is improved, but display complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-positioning display objects according to the intended convergence angle and presentation distance before actual display. This preliminary positioning ensures correct fusion accuracy while reducing real-time computational complexity, as the arrangement is determined in advance based on known parameters.

AI summary
The disclosure relates to a display control device, a display control method, and a recording medium capable of performing more reliable stereoscopic viewing. Whether or not a condition for generating erroneous fusion on a presented image is satisfied on the basis of the display mode of a plurality of display objects arranged side by side in one direction on the presented image at the time of displaying the presented image presented in three-dimensional space. The presented image is expressed by an image for a right eye and an image for a left eye for stereoscopic viewing by using fusion in which the image for a right eye and the image for a left eye are superimposed and recognized as one image. Then, control of applying a predetermined effect to display of the presented image is performed on the basis of the determination result. The present technology can be applied to, for example, a stereoscopic display system using a head-mounted display.
