In-Vehicle Question Output Control for Visit Destination Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle devices often annoy users by repeatedly asking about their destination, leading to user frustration and potential non-response or device shutdown, resulting in incomplete information collection.
Innovation Solution
An information collection device that determines the necessity of outputting questions based on the vehicle's position, number of surrounding facilities, going-out duration, and return status, using a position acquisition section, surroundings search section, question generation section, and question output control section to minimize annoyance and optimize information collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the in-vehicle device outputs a question each time the vehicle is stopped, then the visit destination information can be acquired, but the user feels annoyance and may stop the function
Solution Approach 1:
The system changes the parameter of question output frequency from fixed (every stop) to variable (based on multiple conditions including stop duration, surrounding facilities, and time of day). This resolves the contradiction by adapting the information collection frequency to actual usage patterns, reducing user annoyance while maintaining information acquisition effectiveness.
Solution Approach 2:
The question output control is made dynamic by continuously monitoring vehicle stop duration, searching for surrounding facilities, and adjusting question output decisions in real-time. This dynamic approach allows the system to collect information when conditions are favorable while avoiding unnecessary questions during unfavorable conditions, thus reducing user annoyance.
2Productivity
If the question is output frequently to ensure information collection, then the information acquisition rate increases, but the user experience deteriorates
Solution Approach 1:
The system adjusts the parameter of question output timing based on multiple variables including stop duration thresholds, number of surrounding facilities, and time-based patterns. This optimized parameter configuration maintains high information acquisition rates by asking questions when users are most likely to respond, while minimizing disruptions to user experience.
Solution Approach 2:
The system performs preliminary searches for surrounding facilities and analyzes stop duration patterns before deciding to output a question. This preliminary action ensures that questions are only posed when conditions suggest a high probability of successful information collection, thereby maintaining productivity without compromising user experience.
3Measurement precision
If the system asks questions to identify visit destinations, then the data accuracy improves, but the time required for information collection increases
Solution Approach 1:
The system performs preliminary analysis of stop duration and surrounding facility data before outputting questions. This preliminary action pre-filters situations where information collection is likely to succeed, reducing the total number of questions needed and thereby minimizing time loss while maintaining high identification accuracy.
Solution Approach 2:
The system uses automatically collected data (vehicle position, stop duration, surrounding facilities) to make intelligent decisions about when to collect visit destination information. This self-service approach optimizes the timing and frequency of information collection requests, achieving high accuracy without requiring excessive user interaction time.

AI summary
Annoyance is reduced that is caused to a subject person from which information is collected. An information collection device includes: a position acquisition section 24 that acquires a current position of an own vehicle; a surroundings search section 51 that searches for a facility Qa in surroundings of the own vehicle; a question generation section that generates a question related to a visit destination A of a subject person; a question output necessity determination section that determines whether or not it is necessary to perform output of the question, based on at least one of a result of the acquisition by the position acquisition section 24, the number of results of the search by the surroundings search section 51, and a going-out duration of the subject person; a question output control section that outputs the question, depending on a result of the determination by the question output necessity determination section; and a collection section 53 that collects information on the visit destination A, based on input information input by the subject person in response to the question.
