Solution Overview

Problem

Conventional virtual space technology limits users to experiencing remote spaces by merely copying them, failing to provide an effective experience due to challenges in matching the size and scale of the remote space with the local environment.

Innovation Solution

An information processing system that includes a server, imaging device, and terminal device, which acquires and processes local and remote space information to generate a virtual video on the terminal device, adjusting movement rates to match the scale and position of the user in the remote space, thereby enhancing the experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the remote space is copied using sensor technology, then the user can move in the virtual reality space, but the user cannot effectively experience the remote space due to scale and size mismatch

Engineering Contradiction:
Improveuser experience effectivenessVSAvoidspace scale matching
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by adjusting the movement rate parameter based on the ratio between remote space size and local space size. When the remote space is larger than the local space, the movement rate is set greater than 1 to amplify user movement. When the remote space is smaller, the movement rate is set between 0 and 1 to reduce user movement. This dynamic parameter adjustment resolves the scale mismatch problem and enables effective remote space experience.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the movement rate is adjusted to match the remote space scale, then the user experience is improved, but the system complexity increases due to additional calculations

Engineering Contradiction:
Improveuser experience qualityVSAvoidprocessing system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-calculating the movement rate parameter before the user enters the virtual reality space. The system acquires the size of the remote space and the size of the local space in advance, calculates the ratio, and sets the movement rate parameter beforehand. This eliminates the need for complex real-time calculations during user interaction, thus improving ease of operation while minimizing system complexity.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the local space size is increased to match the remote space, then the user can experience the remote space better, but the physical space requirements increase

Engineering Contradiction:
Improveremote space experienceVSAvoidlocal space area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent applies dimensionality change by introducing a virtual dimension through the movement rate parameter. Instead of physically expanding the local space to match the remote space, the system creates a virtual scaling effect through software-based movement rate adjustment. This allows users to experience large remote spaces within small physical local spaces by manipulating the virtual movement dimension, thus resolving the contradiction without increasing physical space requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
