Navigation Device Pseudo-3D Destination View Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigating to an unknown destination using existing navigation devices can be challenging due to the lack of detailed information about the destination's appearance and surrounding environment, leading to user uncertainty and increased journey time.
Innovation Solution
A navigation device and method that provide a user-selected destination with enhanced pseudo three-dimensional views, including building representations and information markers for entrance and parking locations, to facilitate easier navigation to unfamiliar destinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional map display is used, then device complexity is low, but user uncertainty about destination increases
Solution Approach 1:
The patent transitions from traditional two-dimensional map displays to pseudo-three-dimensional building representations. This dimensional enhancement provides users with a more realistic view of destination buildings and surrounding environment, reducing uncertainty about the destination's appearance and location while maintaining manageable device complexity through software-based rendering.
Solution Approach 2:
The system generates and displays destination preview information before the user arrives at the destination. By showing pseudo-3D building views and surrounding environment in advance, users can familiarize themselves with the destination's appearance and location, reducing arrival uncertainty and search time without requiring complex real-time processing.
2Loss of information
If detailed destination information is provided, then user uncertainty decreases, but processing time increases
Solution Approach 1:
The system provides selectively detailed information rather than complete exhaustive data. It generates pseudo-3D representations and key destination features that are sufficient to reduce user uncertainty about the destination's appearance and location, without processing and displaying all possible detailed information, thus balancing information completeness with processing efficiency.
3Ease of operation
If pseudo three-dimensional views are provided, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system creates simplified pseudo-three-dimensional copies or representations of actual buildings and surrounding environment rather than using full three-dimensional models. This copying approach provides enhanced visual information for easier navigation while keeping the data structure and processing requirements manageable, avoiding the complexity of complete 3D modeling.
