Adaptive Navigation Animation Timing for High-Speed Route Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to adjust the playing speed of navigation animations based on vehicle speed, leading to incomplete display of navigation prompts at critical locations, causing deviations from the intended route.
Innovation Solution
Adaptive adjustment of navigation animation playing speed and visibility based on current vehicle speed, road type, and distance to the location point, ensuring complete display and optimal visibility of navigation prompts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the playing speed of navigation animation is fixed, then the navigation animation can be displayed consistently, but the navigation animation cannot be completely played before the vehicle reaches the front crossroad when vehicle speed is high
Solution Approach 1:
The patent applies dynamics by making the navigation animation playing speed adjustable rather than fixed. The system dynamically changes the playing speed based on real-time vehicle speed detection, allowing the animation to adapt to varying driving conditions. When vehicle speed increases, the animation playing speed increases accordingly, ensuring the animation can be completely played before the vehicle reaches the crossroad.
Solution Approach 2:
The patent changes the parameter of animation playing speed based on vehicle speed. By detecting vehicle speed through the navigation device and adjusting the animation playing speed accordingly, the system ensures that the navigation animation is always fully displayed before the vehicle reaches the destination, regardless of how fast the vehicle is traveling.
2Reliability
If the navigation animation playing speed is increased to match high vehicle speed, then the navigation animation can be completely played before reaching the crossroad, but the navigation animation may not be visible enough when vehicle speed is low
Solution Approach 1:
The patent uses feedback by continuously detecting vehicle speed through the navigation device and adjusting the animation playing speed based on this feedback. The system monitors real-time vehicle speed and dynamically adjusts the animation playing speed to match, ensuring that the navigation animation is always fully displayed and visible to the user, regardless of driving conditions.
3Loss of time
If the navigation animation is displayed earlier to provide sufficient reaction time, then the user has enough time to respond, but the navigation animation may not be visible when the vehicle is far from the crossroad
Solution Approach 1:
The patent applies preliminary action by calculating and displaying the navigation animation in advance based on predicted vehicle speed and distance to the crossroad. The system determines when to start displaying the animation beforehand, ensuring that the user has sufficient reaction time while the animation remains visible. The animation is displayed at an appropriate distance from the crossroad, not too early when visibility would be poor and not too late when reaction time would be insufficient.

AI summary
This application provides a navigation method and device, a storage medium, a program product, and a vehicle, and relates to the field of navigation technologies. The navigation method includes: in a process in which a target device travels toward a first location point, obtaining a first speed at which the target device currently travels; determining a playing parameter of a navigation animation based on the first speed, where the navigation animation indicates a traveling path for the target device to reach the first location point, and the playing parameter indicates at least a playing speed of the navigation animation; and outputting the navigation animation in a visualized manner based on the playing parameter. In this application, the playing speed of the navigation animation may be adaptively adjusted based on the current traveling speed of the target device, so that the navigation animation can be completely played before the target device reaches the first location point, to avoid deviation of the target device from a correct navigation route caused by no correct response made, due to failure in viewing complete prompt information, by a user when a vehicle reaches a first location.
