Navigation Control Unit Adapting Bypass Proposals to User Acceptance Rates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems often bother users with unnecessary bypass proposals, leading to user frustration.
Innovation Solution
An information processing device that acquires a user's acceptance rate for past bypass proposals and outputs proposal information only when the acceptance rate is high, thereby minimizing unnecessary bypass proposals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If bypass proposals are made frequently to ensure users receive all possible route alternatives, then the completeness of route information is improved, but user frustration increases due to unnecessary proposals
Solution Approach 1:
The system monitors user responses to bypass proposals (acceptance or rejection) and uses this feedback to dynamically adjust future proposal behavior. When users reject bypass proposals, the system learns from this feedback and becomes less likely to make similar proposals in the future, thereby reducing user frustration while maintaining information completeness.
Solution Approach 2:
The system dynamically adjusts its bypass proposal strategy based on real-time user behavior patterns. Rather than using a static approach of always proposing bypasses or never proposing them, the system adapts its proposal frequency and timing according to individual user preferences and historical acceptance rates, optimizing the balance between information provision and user experience.
2Ease of operation
If bypass proposals are made only when acceptance rate is high to reduce user frustration, then user experience is improved, but the system may miss opportunities to provide useful bypass information
Solution Approach 1:
The system continuously monitors acceptance rates as feedback signals. When acceptance rates are high, the system increases bypass proposal frequency to provide more useful information. When acceptance rates drop, the system reduces proposals to improve user experience. This feedback loop ensures the system optimizes the balance between providing useful information and maintaining good user experience.
Solution Approach 2:
The system changes the parameter of proposal frequency based on the acceptance rate threshold. By dynamically adjusting this parameter according to user response patterns, the system ensures that bypass information is provided at optimal frequencies - neither too frequently (causing frustration) nor too rarely (missing useful opportunities).

AI summary
The control unit of the information processing device acquires the acceptance rate of the user of the vehicle with respect to the proposal of the bypass in the past when there is a bypass recommendation section in which the bypass is recommended on the route of the vehicle. Then, the control unit of the information processing device outputs the proposal information for proposing to bypass the bypass recommendation section in accordance with the acceptance rate.
