Navigation Display Magnifying Selectable Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for resolving ambiguity in place names entered for navigation devices often fail to clearly distinguish between multiple locations with the same name, leading to user confusion.
Innovation Solution
Displaying graphics of the surroundings of selectable elements at a larger scale than the map section, creating a magnified view that helps users easily identify and select the correct location, with spatial references like center positioning or pointers, and sorting elements by recognition probability for clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If place names are entered via keyboard or voice recognition, then input efficiency is improved, but ambiguity arises when multiple locations share the same name
Solution Approach 1:
The solution segments the location identification process into two stages: first presenting a list of matching place names based on input, then displaying enlarged map sections for each ambiguous location. This segmentation allows users to efficiently filter options textually first, then visually confirm the correct location, resolving the ambiguity without sacrificing input speed.
Solution Approach 2:
The patent transitions from one-dimensional text-based location identification to two-dimensional visual map sections. By displaying enlarged map sections showing surroundings, landmarks, and geographical features, the system adds a spatial dimension to the selection process, enabling users to distinguish between locations with identical names through visual context.
2Measurement precision
If enlarged map sections are displayed for each location, then location identification accuracy is improved, but display complexity increases
Solution Approach 1:
The display dynamically adapts based on user interaction and context. The system presents map sections only for locations that are ambiguous (have matches in the database), not for all possible locations. The display can be updated incrementally as the user navigates through options, reducing unnecessary visual complexity while maintaining identification accuracy.
Solution Approach 2:
Different parts of the display serve different functions: the main area shows the list of matching place names for quick scanning, while smaller inset areas display enlarged map sections showing only the relevant ambiguous locations. This local differentiation optimizes information presentation by showing detailed map views only where needed, rather than uniformly across the entire display.
3Measurement precision
If multiple map sections are displayed simultaneously, then user orientation is improved, but ease of operation deteriorates due to selection difficulty
Solution Approach 1:
The system introduces an intermediary selection mechanism between viewing multiple map sections and final location selection. Users can navigate through ambiguous locations using directional controls or highlighting, with the system maintaining a clear indication of the currently selected option. This intermediary interface simplifies the selection process even when multiple map sections are displayed, preventing cognitive overload.

AI summary
The method involves producing number of selectable elements by a voice recognition device from a spoken element. Graphic arts (200, 210) are produced for each element, where the graphic arts comprise the elements and environment of the selectable elements. A map section of the selectable elements is displayed in a scale on a display device (70) e.g. LCD. The graphic arts are superimposed with a larger scale than the scale of the map section. The graphic arts are displayed with reference to the selectable elements. Detection probabilities of the elements are made in the graphic arts. : An independent claim is also included for a device for performing a method for displaying number of selectable elements. USE : Method for displaying number of selectable elements such as addresses e.g. place names, street names, house numbers and point of interest, of digital road map, for target location input for a navigation device in a motor vehicle (all claimed). Can also be used for a multimedia device, a telephone device or an infotainment device. ADVANTAGE : The graphic arts are displayed with reference to the selectable elements, thus orienting enlarged representation of the selectable elements and environment of the selectable elements in a simple and fast manner, and hence increasing the operating comfort of the user.
