Guide Information Generation for Travel Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traveling assistance technologies often present guide information that is not useful to users, leading to annoyance, as the information is not tailored to individual user characteristics or changing environmental conditions.
Innovation Solution
An information processing device with a recognition unit, guide control unit, and change detection unit that generates and outputs guide information based on user characteristics and detects changes in the environment, ensuring the information is relevant and useful to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If guide information is presented without considering user characteristics and environmental changes, then the system operation is simple, but the usefulness of the guide information decreases and users feel annoyed
Solution Approach 1:
The system performs preliminary actions by storing user characteristics and past environmental data before guide information is needed. The recognition unit captures surrounding environment images and stores them along with user characteristics in advance, so when the user visits the same location again, the comparison can be made quickly without complex real-time processing.
Solution Approach 2:
The system implements feedback by comparing the current surrounding environment with past environment images and detecting changes. This feedback loop allows the system to adapt guide information based on detected environmental changes and user characteristics, improving usefulness while managing complexity through automated comparison algorithms.
2Reliability
If the system stores and processes user characteristics and past environment data, then the usefulness of guide information improves, but the information processing load increases
Solution Approach 1:
The system applies local quality by focusing processing only on relevant aspects of the environment. Instead of processing all environmental data uniformly, the system compares specific features and detects only meaningful changes at the current location, reducing overall processing energy while maintaining accuracy where it matters most.
Solution Approach 2:
The system uses partial action by selectively processing and comparing only the necessary environmental features rather than analyzing every detail. The change detection focuses on significant environmental changes that would affect guide information, avoiding excessive processing of irrelevant data and reducing energy consumption.
3Ease of operation
If the system detects environmental changes and generates customized guide information, then user assistance quality improves, but the response time increases
Solution Approach 1:
The system performs preliminary actions by pre-storing environment images and user characteristics before they are needed for comparison. This allows the change detection and guide information generation to proceed quickly when the user returns to a location, as the baseline data is already prepared and accessible.
Solution Approach 2:
The system uses copying by storing past environment images as reference copies for comparison with current environment. This allows rapid detection of changes by comparing against pre-captured copies, reducing the time needed for real-time analysis while maintaining accurate change detection for generating customized guide information.

AI summary
An information processing device includes: a recognition unit (21) that recognizes a surrounding environment of a current position of a user; a guide control unit (22) that generates guide information corresponding to a characteristic of the user by using a recognition result of the recognition unit and that causes an output device to perform an output thereof; and a change detection unit (23) that detects a changed portion in the surrounding environment of the current position in a case where it is determined that the user has visited the current position in the past, wherein in a case where the change detection unit detects the changed portion, the guide control unit generates the guide information including information causing the user to recognize the changed portion.
