Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing questionnaire survey methods struggle to accurately collect responses from viewers regarding specific scenes in media, as viewers often fail to remember all scenes, leading to inaccurate reflections in survey results.

Innovation Solution

A server apparatus that collects and identifies responses based on ambient sound data from a terminal device, allowing respondents to submit responses during the relevant scene, thereby ensuring accurate scene identification and mixed response avoidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If questionnaire distribution is conducted after media playback, then respondents can provide feedback on the content, but respondents fail to remember all scenes leading to inaccurate survey results

Engineering Contradiction:

Improveaccuracy of questionnaire resultsVSAvoidmemory loss of scenes

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system performs preliminary action by collecting ambient sound data continuously during media playback before the questionnaire response is needed. This allows the server to identify which scene is currently being viewed when the respondent submits their response, eliminating the need for respondents to remember scene details and ensuring accurate scene-specific survey results.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If respondents submit questionnaire responses during media playback, then real-time feedback can be collected, but responses may be mixed with other scenes leading to identification errors

Engineering Contradiction:

Improveresponse collection efficiencyVSAvoidscene identification accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system uses feedback by continuously monitoring ambient sound data during media playback and comparing it with stored sound data of known scenes. When a respondent submits a questionnaire response, the server identifies the current scene by matching the ambient sound, ensuring that each response is accurately associated with the intended scene even as multiple scenes play sequentially.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If ambient sound data collection is implemented, then accurate scene identification is achieved, but device complexity increases

Engineering Contradiction:

Improvescene identification accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies self-service by utilizing the terminal device's existing ambient sound collection capability rather than requiring additional specialized hardware. The server performs the complex task of sound data comparison and scene identification, while the terminal device simply collects and transmits the ambient sound data, dividing the complexity appropriately between client and server.

Inventive Principle:

Principle #25Self-service

AI summary

A server apparatus for accurately collecting responses of questionnaires with regard to a target object including a plurality of scenes is provided. An operation signal for obtaining a time when response operation is performed is received from a terminal device. A time and each scene of the target object is associated in scene information, and a scene of the target object is identified as being a target of the response of the questionnaire, based on the scene information and the obtained time.
