Solution Overview

Problem

Existing virtual space interface systems are limited in user convenience due to reliance on traditional input devices and camera-based interactions, which restrict the amount of information that can be input and require user familiarity with operation units.

Innovation Solution

A virtual space interface device that utilizes a client terminal equipped with a display device, sound output device, sound pickup device, and photographing device to generate display and sound data based on user gestures and positional relationships, allowing for enhanced interaction through hand positioning and facial image analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional operation units (keyboard, pointing device) are used to control virtual space, then users familiar with these devices can operate the system, but user convenience is limited and information input capability is restricted

Engineering Contradiction:
Improveuser convenienceVSAvoidinformation input capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces traditional mechanical operation units (keyboard, pointing device) with a camera-based gesture recognition system. The camera captures hand gestures and facial expressions, which are then processed to control virtual space interactions. This substitution enables more intuitive and versatile information input while improving ease of operation for users regardless of their familiarity with traditional input devices.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If camera-based interaction is used to control virtual space, then user convenience is improved, but the amount of information that can be input is limited

Engineering Contradiction:
Improveuser convenienceVSAvoidinformation input amount
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent segments the face and hand regions within the camera capture area to enable differentiated control. By identifying specific facial features (eyes, mouth, nose) and hand positions, the system can interpret multiple types of gestures and expressions simultaneously. This segmentation allows the system to extract rich information from the camera input, overcoming the limitation of traditional camera-based interaction while maintaining ease of use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds spatial dimensionality to camera-based interaction by analyzing the three-dimensional positioning of hands and facial features. By considering not just the presence of gestures but also their spatial coordinates and relationships, the system can interpret more complex commands and input more information. This dimensional enhancement allows the camera to capture and process a broader range of user intentions.

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

3Adaptability or versatility

If hand gestures are used to control virtual space, then information input capability is enhanced, but the system complexity increases

Engineering Contradiction:
Improveinformation input capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary processing layer between the camera and the virtual space control system. This intermediary component (gesture recognition module) processes the raw camera images to identify hand gestures and facial expressions, converting them into control commands. By separating the camera capture function from the control execution, the system manages complexity more effectively while maintaining enhanced information input capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A virtual space interface device generates display data for causing a client terminal to display an image showing a situation in a virtual space, generates sound data for outputting a user-uttered sound picked up by the terminal into the virtual space, and generates sound data for causing the terminal to output a sound in the virtual space. The display data and the sound data are controlled on the basis of a gesture of the user and a positional relationship between the user and the terminal. A control target differs in accordance with a part of a face area where the user positions the user's hands.
