Shutter Glasses Navigation via Visible Light Signposts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signpost systems on roads lack efficiency in providing relevant navigation information to drivers, as they typically have fixed patterns and require manual identification by drivers, leading to confusion and inefficiency.
Innovation Solution
A signpost-based navigation system using visible light communication technology, where LED road signs emit encoded light signals with navigation information, and shutter glasses control the display of relevant signpost information based on the vehicle's position and navigation path, filtering out unnecessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed pattern signposts are used on roads, then the signpost system is simple to implement, but drivers cannot quickly identify relevant navigation information leading to confusion and inefficiency
Solution Approach 1:
The patent applies dynamics by making the signpost information display adaptive and changeable based on real-time navigation data. The system dynamically updates signpost content according to the vehicle's current position, navigation path, and driver preferences, transforming static fixed-pattern signposts into dynamic information displays that automatically adjust to provide only relevant navigation information.
Solution Approach 2:
The system changes the information content parameter of signposts based on navigation requirements. By modifying which information is displayed (direction, distance, lane guidance) according to the vehicle's position and navigation path, the system optimizes information delivery without requiring physical changes to the signpost infrastructure.
2Loss of information
If all signpost information is displayed to drivers, then complete information is provided, but drivers experience information overload and confusion
Solution Approach 1:
The system extracts only the relevant navigation information from the complete set of signpost data based on the vehicle's current position, navigation path, and driver preferences. By filtering out unnecessary information and displaying only what is currently useful (such as upcoming turns, distance to destination, or lane guidance), the system prevents information overload while maintaining information completeness for the specific navigation context.
Solution Approach 2:
The system applies local quality by customizing the information display according to the specific navigation context and driver needs. Different drivers receive different information based on their preferences and current position, making the information presentation tailored to local requirements rather than providing uniform information to all drivers.
3Productivity
If manual identification of signpost information is required, then the system is simple, but navigation efficiency is reduced due to time-consuming information search
Solution Approach 1:
The system implements self-service by automatically identifying and presenting relevant navigation information without requiring manual search by the driver. The system continuously monitors the vehicle's position, automatically determines which signpost information is relevant based on the navigation path, and displays it prominently, allowing drivers to simply follow the displayed information rather than searching through multiple signposts.
Solution Approach 2:
The system uses feedback from the vehicle's position data and navigation path information to continuously adjust and update the displayed signpost information. This real-time feedback loop ensures that the most relevant information is always displayed, reducing the time drivers need to spend searching for navigation cues.

AI summary
A signpost-based navigation method, a computer readable storage medium, and an electronic device that implements the method. The method comprises: capturing a visible light signal emitted by a road sign, the visible light signal comprising multiple pieces of different signpost information; selecting, according to indication information corresponding to a current position of a vehicle on a navigation path, at least one piece of signpost information from the multiple pieces of different signpost information as signpost information of a current signpost; and controlling a shutter of shutter glasses so as to display the current signpost through the shutter glasses.
