Utilizing user interaction data, such as content operation history, to correct estimated position information based on pre-stored coordinates and reliability information, thereby improving indoor positioning accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If indoor positioning is performed using sensing data from the user terminal, then positioning can be achieved indoors, but position estimation accuracy deteriorates due to sensor noise

Engineering Contradiction:

Improveposition estimation accuracyVSAvoidposition estimation reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system uses content operation history as feedback to correct position estimation errors. The action recognition unit detects user actions (playing content near specific works), and the position information correction unit uses this feedback to adjust the estimated position, thereby improving both accuracy and reliability of position estimation indoors

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces content operation history as an intermediary factor between the sensing data and the final position determination. This intermediary helps bridge the gap caused by sensor noise by using user behavior patterns to infer and correct position information

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If environmental equipment like beacons or Wi-Fi fingerprinting is deployed, then positioning accuracy can be improved, but device complexity and cost increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables the user terminal to perform self-correction of position information using its own sensing data and content operation history. This self-service approach eliminates the need for external environmental equipment like beacons or Wi-Fi fingerprinting systems, reducing device complexity while maintaining positioning accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the positioning correction function from external environmental equipment and relocates it to the user terminal itself. By using the terminal's own sensing data and content operation history, the system eliminates dependency on external infrastructure, thereby reducing system complexity

Inventive Principle:

Principle #2Taking out (Extraction)
