Solution Overview

Problem

Current satisfaction survey methods in field spaces, such as tourist spots and exhibition halls, face low participation rates, high costs, and lack real-time data collection, particularly due to manual processes and the difficulty in accurately analyzing facial expressions for satisfaction levels.

Innovation Solution

A system utilizing video cameras to capture and recognize viewer motions, such as hand signals, and analyze features like gender and age, allowing for real-time satisfaction analysis and grouping, thereby reducing costs and improving participation through non-contact, motion-based feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual survey methods using questionnaires are used, then survey implementation is simple, but participation rate is low and time consumption is high

Engineering Contradiction:
Improvesurvey implementation simplicityVSAvoidparticipation rate
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual questionnaire distribution and collection with an automated image recognition system using cameras and AI algorithms. The system automatically captures images, detects hand gestures, recognizes satisfaction levels, and stores results in a database, eliminating the need for physical questionnaires and manual data collection processes.

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

Solution Approach 2:

The system enables viewers to automatically complete the satisfaction survey by simply making hand gestures that are captured by the camera. The automated recognition and analysis system processes the gestures without requiring viewer interaction beyond the gesture itself, making the survey process self-service oriented and significantly improving participation rates.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If specialized survey institutions are hired for face-to-face surveys, then data collection accuracy is high, but cost is considerable

Engineering Contradiction:
Improvesatisfaction data accuracyVSAvoidsurvey cost
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent replaces human surveyors with an automated system comprising cameras, image processing units, and databases. The system uses computer vision technology to capture images, detect hand gestures, recognize satisfaction levels, and store results automatically, eliminating the need for hired surveyors while maintaining measurement accuracy through standardized algorithmic analysis.

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

Solution Approach 2:

The system creates a digital copy of the satisfaction survey process through automated image capture and digital data storage. Instead of relying on human observers to record and interpret satisfaction levels, the system captures visual information, processes it through algorithms, and stores digital results, providing consistent and accurate measurements without human intervention costs.

Inventive Principle:
Principle #26Copying

3Device complexity

If traditional survey methods are used, then implementation is straightforward, but real-time monitoring is not possible

Engineering Contradiction:
Improvesurvey system simplicityVSAvoiddata analysis time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent implements continuous real-time monitoring through an automated system that continuously captures images, processes hand gestures, recognizes satisfaction levels, and stores results in a database without interruption. The system operates continuously as viewers pass through the exit, enabling real-time satisfaction monitoring and immediate data availability for analysis and decision-making.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system replaces manual data collection and analysis processes with automated image recognition and digital processing. Cameras continuously capture images, AI algorithms instantly analyze hand gestures and determine satisfaction levels, and results are immediately stored and made available, eliminating the time delay inherent in manual survey methods while maintaining system simplicity through integrated automation.

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

AI summary

The present invention relates to a system for surveying satisfaction through motion recognition in a field space, in which when a viewer exiting from a viewing site space such as a tourist spot, an exhibition hall or the like expresses an evaluation as a motion such as a hand signal, a gesture or the like in front of an exit, the motion is captured and recognized using a video camera, and viewer's satisfaction is investigated, and the system includes: a video acquisition unit for acquiring a video of a viewer captured using the camera device, together with shooting information of the video of the viewer; a satisfaction extraction unit for detecting a motion signal by recognizing a motion of the viewer from the video of the viewer, and extracting a satisfaction level corresponding to the detected motion signal; an attribute extraction unit for extracting attribute values from the video of the viewer or the shooting information of the video of the viewer, and setting the extracted attribute values as attributes of a corresponding satisfaction level; and a statistical analysis unit for calculating statistical values by statistically analyzing data on the satisfaction level, for each attribute combination by combining the attributes. According to the system as described above, as a viewer expresses a satisfaction level by a simple body motion at an exit and the body motion is recognized and analyzed, an effect of saving time and money required for satisfaction survey and increasing viewer's participation can be obtained.
