Solution Overview

Problem

Conventional stereoscopic display systems fail to adjust parallax effectively when a user interface is superimposed on a three-dimensional virtual space, requiring users to change focal length based on their viewing style, leading to discomfort.

Innovation Solution

A display control program that allows separate adjustment of parallax for user interfaces and three-dimensional virtual spaces, using input information from users to generate stereoscopic images with adjustable parallax for both, ensuring comfortable viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed parallax is set for the user interface by the game maker, then the user interface can be displayed consistently, but the user cannot adjust the parallax according to their own viewing style

Engineering Contradiction:
Improveparallax adjustment flexibilityVSAvoidparallax control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the parallax adjustment function into two independent segments: one for adjusting the parallax of the three-dimensional virtual space and another for adjusting the parallax of the user interface. This segmentation allows each component to be adjusted separately according to different requirements, resolving the contradiction between adaptability and complexity by providing targeted adjustment capabilities without requiring a complete system redesign.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic adjustment capabilities where the parallax of the user interface can be changed in real-time based on user input, rather than being fixed. This dynamic adjustment allows the system to adapt to different viewing styles and situations, improving versatility while maintaining manageable complexity through intuitive control mechanisms.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the parallax of the three-dimensional virtual space is adjusted, then the stereoscopic effect of the virtual space is improved, but the user interface parallax does not adapt independently

Engineering Contradiction:
Improveindependent parallax controlVSAvoidfocal length adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent separates the parallax control into distinct functions: one for the three-dimensional virtual space and another for the user interface. This segmentation enables independent adjustment of each element, allowing users to optimize the stereoscopic effect of the virtual space without being constrained by fixed user interface parallax settings, thereby improving adaptability while maintaining ease of operation through dedicated controls.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different parallax adjustment characteristics to different parts of the display system. The three-dimensional virtual space can have its parallax adjusted to enhance depth perception, while the user interface can have its parallax adjusted separately to maintain readability and usability. This local differentiation resolves the contradiction by allowing each component to have optimized parallax settings suited to its specific function.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a single parallax setting is used for both user interface and three-dimensional virtual space, then the system is simple to operate, but users must change focal length depending on viewing style

Engineering Contradiction:
Improveparallax adjustmentVSAvoidviewing style adaptation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent divides the parallax adjustment into separate controls for the user interface and the three-dimensional virtual space. This segmentation maintains ease of operation by providing intuitive, dedicated controls for each element while simultaneously improving adaptability by allowing users to adjust each component according to their specific viewing style and preferences.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic parallax adjustment capabilities that allow users to modify the parallax settings in real-time based on their viewing style. This dynamic approach maintains ease of operation through user-friendly controls while significantly improving adaptability by enabling customization for different viewing conditions and preferences.

Inventive Principle:
Principle #15Dynamics

AI summary

A virtual object placed in a three-dimensional virtual space and a user interface are stereoscopically displayed on an upper LCD of a game apparatus. An image used for adjusting a display position of the user interface in the depth direction is displayed on a lower LCD. A user adjusts a UI adjustment slider by using a touch pen to adjust the parallax of the user interface. This allows the adjustment of the parallax of the user interface separately from the parallax of the three-dimensional virtual space, and thereby the depth perception of the user interface can be adjusted.
