Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sensory effect technologies in 4D theaters fail to account for individual user preferences, leading to varying levels of immersion and satisfaction due to differences in sensitivity to sensory effects such as wind, touch, smell, etc., among users.

Innovation Solution

A sensory effect representation apparatus and method that predicts user status by collecting and analyzing user data to recommend personalized sensory effects, incorporating feedback loops to refine recommendations based on user preferences and population patterns, and utilizing a learning server to optimize sensory effect provision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional video and audio apparatuses are used to provide multimedia content, then visual and auditory quality can be maximized, but user immersion and satisfaction are limited due to lack of additional sensory stimulation

Engineering Contradiction:

Improvesensory effect provisionVSAvoiduser preference information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system collects user feedback on sensory effects and uses this feedback to adjust and personalize future sensory effect recommendations. The feedback unit receives user responses and the recommendation unit adjusts the sensory effect selection based on this information, creating a closed-loop system that continuously improves personalization accuracy.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of user status information before providing sensory effects. The recommendation unit predicts user status and pre-selects appropriate sensory effects based on this prediction, ensuring that the sensory effects are tailored to the user's current state before actual delivery.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If sensory effects are provided to all users uniformly, then implementation is simple, but user satisfaction varies due to individual differences in sensitivity to sensory effects

Engineering Contradiction:

Improveuser status prediction accuracyVSAvoidsystem structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments users into different groups based on their predicted status and preferences. The recommendation unit provides different sensory effects to different user segments rather than a uniform approach, allowing personalized treatment while managing complexity through systematic classification.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The recommendation unit acts as an intermediary between the user status analysis and the sensory effect delivery. It processes user status information, predicts preferences, and selects appropriate sensory effects, thereby simplifying the overall system architecture while achieving precise personalization.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If user status prediction and personalized recommendation systems are implemented, then user immersion and satisfaction are enhanced, but system complexity increases due to additional components and processing requirements

Engineering Contradiction:

Improvesensory effect recommendationVSAvoidapparatus structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The recommendation unit serves multiple functions: it analyzes user status information, predicts user preferences, selects appropriate sensory effects, and adjusts recommendations based on feedback. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing system complexity while achieving personalized recommendations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Provided is a sensory effect representation apparatus including a collection unit configured to collect user status information about a user status, a storage unit configured to store sensory effects; an analysis unit configured to analyze the user status information to generate a user status prediction pattern, a sensory effect recommendation unit configured to recommend a sensory effect corresponding to the user status prediction pattern, from among the stored sensory effects; and a sensory effect provision unit configured to read a sensory effect corresponding to the sensory effect prediction pattern, from the storage unit and provide the read sensory effect. Accordingly, it is possible to provide a sensory effect appropriate for a user characteristic by predicting a user status and reflecting a feedback on a recommended sensory effect.
