Solution Overview

Problem

Conventional techniques for displaying images in virtual three-dimensional spaces, such as head-mounted displays, limit user experience by directly correlating user movement and hand motion with object motion at the same rate, resulting in only limited sensations being presented.

Innovation Solution

An information processing apparatus that detects movement in a real space and computes corresponding positions in a virtual space using detected movement information, allowing for the placement of virtual objects and rendering of images that enhance user experience by varying the rate of object movement in the virtual space relative to real space movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If user movement and hand motion are directly correlated with object motion at the same rate, then the control is simple and direct, but the user experience is limited and lacks variety

Engineering Contradiction:
Improveuser experience varietyVSAvoidmotion mapping complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the motion mapping relationship variable rather than fixed. The system dynamically adjusts the correlation between user movement and object motion based on virtual object attributes, allowing the mapping ratio to change according to the situation. This enables diverse user experiences without requiring complex additional hardware, as the complexity is managed through software-based adaptive mapping.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the motion mapping ratio is fixed at 1:1, then the system is simple to implement, but it presents only limited sensations to the user

Engineering Contradiction:
Improvesensory experience diversityVSAvoidmapping system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements parameter changes by varying the motion mapping ratio based on virtual object attributes. Instead of using a fixed 1:1 mapping, the system adjusts the mapping parameters dynamically according to the characteristics of different virtual objects, enabling diverse sensory experiences while managing complexity through parameter-based control rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If different types of motion mapping are implemented based on virtual object attributes, then user experience is enhanced, but the processing complexity increases

Engineering Contradiction:
Improveinteractive experience qualityVSAvoidprocessing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-defining motion mapping rules and ratios based on virtual object attributes before runtime. The system establishes the mapping relationships in advance according to object characteristics, which allows for efficient real-time processing during user interaction without requiring complex on-the-fly calculations, thus balancing experience quality with processing efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is an information processing apparatus which detects an amount of movement in a real space of a target point concerning a predetermined target in the real space, computes a position in a virtual space of a virtual object by using information about the detected amount of movement, disposes the virtual object at the computed position, and sets information about the virtual space.
