Augmented Reality Map Overlay for Handheld Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems fail to provide effective navigation to nearby points of interest, requiring users to switch applications or orientations, which can be challenging for those with a poor sense of direction, especially when street signs are missing or indecipherable.
Innovation Solution
A method and system that overlays search results and directional maps onto a video feed, allowing users to select points of interest and receive updated navigation information, using a handheld device that detects geographic position, camera direction, and tilt, enabling real-time augmented reality map display and orientation assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user switches applications to get navigation directions, then the user can access detailed route information, but the user experience is disrupted and orientation is lost
Solution Approach 1:
The patent merges navigation directions with the augmented reality view by overlaying directional indicators, route paths, and turn instructions directly onto the camera feed. This allows users to access detailed navigation information without switching applications, maintaining continuous visual context and eliminating the disruption of switching between apps.
2Measurement precision
If the system provides turn-by-turn directions, then navigation accuracy is improved, but the user must mentally correlate directions with real-world objects
Solution Approach 1:
The patent introduces visual intermediary elements including directional arrows, route paths, and highlighted turn instructions overlaid on the camera feed. These visual mediators bridge the gap between abstract turn-by-turn directions and real-world objects, helping users with poor spatial orientation skills by providing clear visual cues that directly indicate which way to turn and where to go, eliminating the need to mentally correlate directions with physical objects.
3Loss of information
If the device displays augmented reality information, then the user can see nearby points of interest, but the display becomes cluttered with multiple information layers
Solution Approach 1:
The patent applies local quality by displaying different types of information at different locations and with different visual characteristics. Points of interest are marked with icons and labels at appropriate distances and orientations, while navigation directions are overlaid as directional indicators and route paths. This localized presentation organizes information spatially, making the display less cluttered while maintaining comprehensive information availability.
Data Source
AI summary
A handheld communication device can capture and display a real-time video stream. The handheld communication device detects a geographic position and camera direction of the handheld communication device. A route is identified from the geographic position of the handheld communication device to a point of interest. The captured video stream is visually augmented with an indicator indicating a direction to travel to the point of interest. The indicator is overlaid on the captured real-time video stream.
