Interactive Navigation Display Using Graphical Road Sign Representations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack innovative features and interaction methods to enhance user experience, particularly in providing dynamic and interactive navigation guidance using graphical representations of geographic objects and signs.
Innovation Solution
A navigation system that utilizes a graphics user interface to display scalable vector graphics images of path signs, allowing users to interact with these representations to receive navigation-related functions, such as route calculations and highlighting of geographic features, through touch inputs and selection of textual characters, symbols, or icons, which can be displayed with or without a corresponding map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional navigation displays are used showing only maps and routes, then the navigation function is provided, but user engagement and interaction are limited
Solution Approach 1:
The patent creates a digital copy of real-world road signs by capturing images of physical signs and integrating them into the navigation display. This allows users to interact with familiar sign representations directly on the screen, enabling new interaction methods while maintaining simplicity. The copied sign images serve as interactive elements that users can select, tap, or gesture toward to receive navigation instructions.
Solution Approach 2:
The patent introduces road sign images as an intermediary between the user and the navigation system. Instead of directly interacting with abstract map data or route information, users interact with visual representations of road signs that naturally guide their attention. This intermediary layer enhances user engagement by leveraging the intuitive nature of road signs while mediating the complex navigation data processing.
2Adaptability or versatility
If static map displays are used, then navigation information is provided, but dynamic and interactive guidance is lacking
Solution Approach 1:
The patent transforms the static navigation display into a dynamic system by incorporating captured road sign images that can be selected and interacted with in real-time. The system dynamically responds to user gestures (taps, swipes, holds) on sign images, providing adaptive navigation guidance based on user interaction. This creates a versatile, interactive experience while managing system complexity through gesture recognition and image processing.
Solution Approach 2:
The patent makes the road sign images multi-functional by enabling various interaction modes (tap for basic information, hold for detailed instructions, swipe for alternative routes). This universal approach allows a single visual element to serve multiple navigation functions, enhancing adaptability while avoiding the need for separate interfaces for different navigation tasks.
3Loss of information
If detailed navigation information is provided through traditional interfaces, then route guidance is given, but user engagement is reduced
Solution Approach 1:
The patent utilizes visual changes in the road sign images (such as highlighting, color changes, or visual feedback) to convey navigation information and confirm user interactions. These visual transformations provide intuitive feedback that enhances user engagement while maintaining complete navigation information delivery through the same interactive sign interface.
4Ease of operation
If interactive features are added to navigation displays, then user engagement improves, but interface complexity increases
Solution Approach 1:
The patent segments the navigation interaction into distinct gesture types (tap, hold, swipe) each associated with specific functions. This segmentation allows the system to provide rich interactive features while managing complexity by clearly defining and separating different interaction modes, making the interface more intuitive and easier to implement.

AI summary
One or more systems, devices, and/or methods for providing and/or using a navigation/geographic feature are disclosed. For example, a method of operation of a navigation system may include providing a graphics user interface. A data representation of a geographic object, such as a path sign or icon, text, or character thereof, is provided in the graphics user interface. The data representation of the path sign may be provided as a feature of a navigation display. Input identifying a portion of the data representation of the geographic object is received. A navigation-related function is provided based on receiving the input.
