3D Extension Screen Lane Guidance for Intersection Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems provide lane information using 2D images, which can cause confusion and only verify lane information when close to an intersection point, failing to effectively guide users in changing lanes safely and efficiently.
Innovation Solution
A method and apparatus that utilize a 3D extension screen to display lane information for each intersection point, with the lane guide unit verifying approaching distances and creating a lane guide screen that highlights the target driving lane differently from others, including real-time distance guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If lane information is provided using a 2D image, then the device complexity is reduced, but the user recognition accuracy and safety of lane changing deteriorates
Solution Approach 1:
The patent transitions from 2D image-based lane guidance to a 3D extension screen that overlays lane information in three-dimensional space. This dimensional change allows the system to maintain computational simplicity while significantly improving lane recognition accuracy and spatial context for users, directly resolving the contradiction between device complexity and recognition precision.
2Loss of time
If lane information is verified only when closely approaching the intersection point, then the information processing time is reduced, but the user reaction time and safety deteriorates
Solution Approach 1:
The system performs preliminary verification of lane information at intersection points before the vehicle actually reaches them. By pre-identifying and displaying lane guidance information in advance, the system eliminates the delay between detecting the intersection and providing guidance, thereby improving both response time and safety without significant processing overhead.
3Loss of information
If all lane information is displayed equally, then the information completeness is improved, but the user attention focus and lane identification clarity deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of lane information based on their importance. The target driving lane is highlighted with enhanced visual attributes (such as brighter color or distinct marking) compared to other lanes, enabling users to quickly identify the correct lane while still receiving complete lane information. This resolves the contradiction by maintaining information completeness while improving operational clarity.
