Voice Guidance Route Comparison for Alternative Direction Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems do not provide users with information on what happens if they deviate from the recommended route, limiting their ability to make informed decisions about alternative directions.
Innovation Solution
An information processing device with a voice guidance unit that calculates and compares a new route to the destination when a user requests information on a different direction, providing details on travel time, distance, and cost differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation device provides only the guide route information, then the device complexity is reduced and ease of operation is improved, but the user cannot make informed decisions about alternative directions
Solution Approach 1:
The system pre-calculates and stores multiple alternative routes along with their attributes (travel time, distance, tolls) before the user needs them. When a user requests alternative route information, the pre-computed data is immediately retrieved and presented, eliminating the need for complex real-time calculations and enabling informed decision-making without increasing operational complexity
2Loss of information
If the voice guidance unit provides detailed comparison information for alternative routes, then the user can make informed decisions, but the information output complexity increases
Solution Approach 1:
The route comparison information is segmented into distinct, manageable attributes such as travel time, distance, and toll costs. Each attribute is processed and presented separately through voice guidance, allowing the system to provide comprehensive route comparison information without overwhelming the user or requiring excessively complex information processing
3Ease of operation
If the system calculates multiple alternative routes with different attributes, then the user convenience is improved, but the calculation time and processing power required increase
Solution Approach 1:
Multiple alternative routes with their attributes (travel time, distance, tolls) are pre-calculated and stored in the system before the user needs them. This preliminary computation allows the system to quickly retrieve and present route options when requested, improving user convenience without incurring significant calculation delays during actual use
Solution Approach 2:
The system focuses calculations on locally relevant alternative routes near the user's current position and intended destination, rather than computing all possible routes globally. This localized approach reduces the overall calculation burden while still providing sufficient alternative options for informed decision-making

AI summary
The information processing device includes a voice guidance unit configured to acquire a current position of the mobile body and perform voice guidance along a route to a destination. When an information request by a user is made by designating a direction different from the direction indicated by a current route at a guide point, the voice guidance unit outputs information on a comparison between the current route and a route to the destination advancing in a designated direction.
