Navigation System Graphical Destination Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges in improving operability, particularly in efficiently inputting destination points and providing effective route indications to users.
Innovation Solution
A navigation system for motor vehicles that includes an output device for optical or acoustic route indications and an input device with a touch panel or screen for selecting geocoded graphics or images, allowing users to input destination points, with the option to store and display image data in EXIF format, and utilizing a camera to record and geocode environmental images for route determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional text-based destination input methods are used, then the system structure remains simple, but user interaction efficiency and operability deteriorate
Solution Approach 1:
The patent uses graphical representations (icons, images, or visual symbols) as copies of destination points to replace traditional text-based input methods. Users can select destinations by interacting with visual representations rather than typing addresses, significantly improving input efficiency while maintaining relatively simple system architecture through the use of standard display and input devices
Solution Approach 2:
The patent replaces the mechanical/text-based input mechanism with a graphical user interface mechanism. Instead of requiring users to type or speak destination addresses, the system presents visual representations of destinations that can be selected through mouse clicks, touchscreen interactions, or other graphical input methods, thereby improving ease of operation
2Ease of operation
If multiple graphics or images are displayed simultaneously, then destination selection becomes more intuitive, but display space requirements increase
Solution Approach 1:
The patent segments the display of destination options into multiple manageable groups or categories. Instead of displaying all possible destinations at once, the system organizes them into sections that can be navigated through scrolling, paging, or categorical filtering, allowing intuitive selection while managing display space efficiently
Solution Approach 2:
The patent adds dimensional elements to the display interface, such as vertical scrolling, horizontal paging, or multi-level menus, to accommodate multiple graphics or images. This allows the system to present more destination options intuitively by utilizing additional spatial dimensions rather than simply expanding the basic display area
3Measurement precision
If geocoded images are stored and displayed, then route determination accuracy improves, but data storage requirements increase
Solution Approach 1:
The patent applies local quality by storing and displaying geocoded images only for specific locations or regions of interest rather than universally for all areas. The system selectively captures and stores images at destinations or along recommended routes, maintaining high accuracy for relevant locations while minimizing unnecessary data storage for areas that are not part of the navigation context
Data Source
AI summary
In a navigation system, e.g., for a motor vehicle, for determining the route from a location of the navigation system to a destination point, the navigation system includes an output device for outputting the route and/or a direction indication that corresponds to the route, and an input device for inputting the destination point, graphics or images of selectable destination points being representable for the input of a destination point.
