3D Destination View Generation for Navigation Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users navigating to unfamiliar destinations face uncertainty and increased journey time due to lack of visual information about the destination, such as building appearance and nearby facilities, which is not adequately addressed by current navigation devices.
Innovation Solution
A navigation device and method that includes a processor, input interface, and display capable of generating and showing a three-dimensional representation of a selected destination's building, along with nearby facilities, to assist users in identifying and navigating to the location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional 2D map displays are used for navigation, then device complexity is kept simple, but users cannot visually identify unfamiliar destinations and experience increased uncertainty and journey time
Solution Approach 1:
The patent transitions from traditional 2D map displays to 3D building models and virtual camera views, adding a spatial dimension to destination visualization. This allows users to see building shapes, heights, and surrounding facilities in three dimensions, providing comprehensive visual information about unfamiliar destinations while maintaining manageable device complexity through software-based rendering.
Solution Approach 2:
The patent creates virtual copies of real-world buildings and environments using 3D models. These digital replicas include building geometries, textures, and virtual camera views that mimic real-world perspectives, allowing users to preview destinations before arrival without requiring physical presence or complex additional hardware.
2Loss of time
If 3D building models and virtual camera views are generated and displayed, then users can clearly identify destinations and reduce journey time, but device complexity and processing requirements increase
Solution Approach 1:
The system generates 3D building models, virtual camera views, and destination visualizations in advance before the user arrives at the destination. This preliminary rendering allows users to preview the destination and surrounding facilities ahead of time, enabling better route confirmation and destination identification without requiring complex real-time processing during the actual journey.
Solution Approach 2:
The 3D building models and virtual camera views serve multiple functions: they provide destination identification, confirm route accuracy, display surrounding facilities, and reduce user anxiety about unfamiliar locations. This multi-functionality justifies the increased processing complexity by delivering comprehensive navigation assistance that addresses multiple user needs simultaneously.
