Solution Overview

Problem

Existing navigation devices do not record or utilize user actions at points of interest (POIs), limiting the ability to provide personalized and informative navigation experiences.

Innovation Solution

An information processing device that detects user rides in a vehicle, asks questions about actions taken at POIs using a microphone and speaker, and stores the answers in an action history database associated with positional information, allowing for accurate recording of user actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the navigation device simply displays POIs with high usage frequency, then the device complexity is reduced, but the loss of information about user actions occurs

Engineering Contradiction:
Improvesystem complexityVSAvoiduser action information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The system automatically detects user rides through ride detection devices and collects action information without requiring manual input from users, enabling the system to self-acquire valuable user behavior data while maintaining simplicity in user interaction

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces ride detection devices as intermediaries to automatically capture user presence information, and uses question output devices as mediators to collect action information, thereby obtaining detailed user behavior data without significantly increasing system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the navigation device asks questions to users about actions at POIs, then the accuracy of user action recording is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveaction recording accuracyVSAvoiduser interaction convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system asks questions about user actions at specific periodic moments (when the user rides in the vehicle after visiting a POI), rather than continuously, thereby obtaining accurate action information while minimizing disruption to user experience

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system automatically detects ride events and triggers questions without requiring users to manually initiate recording, making the process convenient while maintaining accurate data collection through automated timing and context-aware questioning

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the navigation device stores detailed action information, then the adaptability of the system is improved, but the device complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoiddata processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments information storage into distinct components: ride detection data, POI identification data, and user action answer data are stored separately in the storage device, allowing detailed information collection while maintaining organized, manageable data structures that reduce processing complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller acts as an intermediary that automatically processes and associates collected data with map information and POI data, enabling the system to handle complex data relationships without requiring complex user-side processing or manual intervention

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information processing device (100) includes a controller (60), a ride detection device (a sensor group 50) configured to detect a ride of a user (80), a storage device (53) configured to store action data of the user (80), an output device (a speaker 54) configured to output question data for requesting an answer from the user (80), and an input device (a microphone 52) configured to receive an input from the user (80). The controller (60) outputs, from the output device, output data including at least a question regarding an action of the user (80) taken before riding in a vehicle (40) in accordance with positional information of the vehicle (40) when detecting the ride of the user based on a signal acquired from the ride detection device, acquires an answer to the question from the user as input data via the input device, and associates the input data with the positional information of the vehicle (40) or a POI to store the associated data in a storage device (53).
