Solution Overview

Problem

Conventional layout design support apparatuses cannot effectively capture and specify users' perceptions of spaces, as they primarily focus on analyzing layout changes rather than understanding individual user experiences and emotional responses to virtual reality spaces.

Innovation Solution

An information output apparatus and method that acquires and associates detection information of user reactions, such as looking-around motions and brain wave patterns, with video playback positions in virtual or augmented reality spaces, allowing for the output of recognition results that reflect user perceptions, enabling designers to grasp and evaluate space design based on user experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If layout design support apparatus analyzes layout changes to specify recommended layout mode, then layout optimization is improved, but user perception understanding deteriorates

Engineering Contradiction:

Improvelayout optimizationVSAvoiduser perception understanding

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system introduces feedback by detecting user reactions (eye movements, attention duration, emotional responses) while viewing virtual reality spaces and using this feedback to specify user perception. This closes the loop between user experience and system analysis, allowing the apparatus to understand not just layout changes but how users actually perceive and emotionally respond to those changes.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces detection information as an intermediary that mediates between the user's internal perception and the external analysis system. By detecting physiological and behavioral indicators (eye tracking, attention patterns, emotional responses), the system creates an observable proxy for subjective user perception, enabling objective analysis of subjective experiences.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If conventional apparatus focuses on layout change operations, then layout analysis capability is improved, but space perception detection deteriorates

Engineering Contradiction:

Improvelayout analysis capabilityVSAvoidspace perception detection

Core Design Contradiction:

Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The system replaces mechanical observation of layout changes with physiological and behavioral detection methods. Instead of merely tracking mouse movements or layout modifications, the apparatus uses eye tracking, attention duration measurement, and emotional response detection to capture genuine user perception of space, substituting mechanical interaction data with biological signal data.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Detection information serves as an intermediary that translates invisible cognitive processes (perception, emotional response) into measurable data. By detecting eye movements, attention patterns, and physiological responses, the system creates observable proxies for internal mental states, making space perception detectable and measurable.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If user perception data is collected through detection information, then user experience understanding is improved, but system complexity deteriorates

Engineering Contradiction:

Improveuser experience understandingVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The detection information generating unit performs multiple functions simultaneously: it detects eye movements, measures attention duration, and captures emotional responses using integrated sensors and processing algorithms. This multi-functional approach consolidates what could be separate complex systems into a unified detection module, reducing overall system complexity while comprehensively capturing user experience.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges layout analysis, user behavior tracking, and emotional response detection into a single integrated system. By combining these functions that could operate separately into one unified apparatus, the system reduces complexity through integration while maintaining comprehensive user perception analysis capabilities.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An information output apparatus (3) includes an acquisition unit (341) that acquires detection information indicating a detection state of a predetermined reaction of a user when the user views a predetermined space which is a virtual reality space or an augmented reality space, and an output unit (342) that outputs information indicating the predetermined space and the detection information acquired by the acquisition unit (341) in association with each other. The acquisition unit (341) acquires detection information in which (i) the detection state of the predetermined reaction when the user watches the video showing the predetermined space and (ii) information indicating a playback position of the video are associated with each other, and the output unit (342) outputs information indicating the detection state of the predetermined reaction for each playback position of the video.
