Solution Overview

Problem

Existing stereoscopic viewing technologies face challenges in comfortably imparting binocular parallax to users due to inconsistencies between adjustment distance and convergence distance, leading to discomfort during binocular stereoscopic viewing.

Innovation Solution

An information processing apparatus that determines and adjusts the display method for objects in a virtual space based on the positional relationship between the object and the user's viewpoint, dynamically varying the binocular parallax by switching between different display methods, such as presenting different images or the same image to the user's eyes, to maintain comfortable viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a binocular parallax is imparted by presenting different images to the right and left eyes, then stereoscopic viewing capability is improved, but image fusion becomes difficult and viewing comfort deteriorates

Engineering Contradiction:

Improvestereoscopic viewing capabilityVSAvoidimage fusion

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies dynamics by making the binocular parallax adjustable and variable rather than fixed. The control unit dynamically changes the binocular parallax based on the user's head motion detection, allowing the system to adapt the degree of image differentiation between left and right eyes in real-time, thus maintaining image fusion while preserving stereoscopic viewing capability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of binocular parallax dynamically. By detecting head motion and adjusting the binocular parallax parameter accordingly (reducing it when head motion is detected), the system maintains optimal conditions for image fusion while still providing stereoscopic viewing when appropriate

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the same image is presented to both eyes to maintain image fusion, then viewing comfort is improved, but binocular parallax impartation becomes less flexible

Engineering Contradiction:

Improveimage fusionVSAvoidbinocular parallax flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically switches between presenting identical images and presenting different images with binocular parallax based on detected head motion. When no head motion is detected, full binocular parallax is applied for stereoscopic viewing; when head motion is detected, binocular parallax is reduced or eliminated to maintain image fusion, thus achieving both flexibility and reliability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by detecting the user's head motion and using this information to adjust the binocular parallax. The detection unit continuously monitors head position, and the control unit adjusts image presentation based on this feedback, creating a closed-loop system that adapts to user behavior to maintain both stereoscopic capability and image fusion

Inventive Principle:

Principle #23Feedback
