Navigation Control Device Category-Based Destination Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems overwhelm users with numerous suggested destinations, making it difficult to select a suitable option due to lack of context and distance estimation, especially when driving, as they require users to review multiple routes simultaneously.
Innovation Solution
A control device and method that categorize destinations, allowing users to select a primary category and display secondary options from other categories differently, providing an overview and enabling users to prioritize primary destinations while maintaining context and distance information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional navigation systems display all suggested destinations, then the user receives comprehensive destination information, but the user interface becomes overwhelming and difficult to navigate
Solution Approach 1:
The patent divides the list of suggested destinations into multiple categories (e.g., shopping, dining, entertainment, services) and allows users to select specific categories of interest. This segmentation reduces the overwhelming quantity of destinations by presenting only relevant ones, while still providing access to all destinations through category selection.
Solution Approach 2:
The patent applies different display qualities and levels of detail to different destinations based on their category and relevance. Primary destinations in the selected category are displayed with full information, while other destinations are displayed with reduced information or grouped together, creating a hierarchical display structure that manages information density.
2Loss of information
If users review detailed information for each destination, then the user can make informed decisions, but the time required for selection increases significantly
Solution Approach 1:
The patent performs preliminary categorization and filtering of destinations before presentation to the user. By pre-organizing destinations into categories and allowing users to select categories of interest, the system reduces the number of destinations requiring detailed review, thereby reducing selection time while maintaining information quality for relevant destinations.
Solution Approach 2:
The patent displays full information for only the selected category of destinations, while providing summarized or grouped information for other categories. This partial action approach provides sufficient information for decision-making regarding the selected category without overwhelming the user with excessive information from all categories, thus reducing selection time.
3Device complexity
If users lack context about destination locations, then the interface becomes simpler, but users cannot estimate distance or plan routes effectively
Solution Approach 1:
The patent merges the category selection interface with a map display showing the locations of destinations within the selected category. This combination provides spatial context and distance information without significantly increasing interface complexity, as the map serves dual purposes of location display and visual navigation aid.

AI summary
Exemplary embodiments relate to a control device (1) for marking a plurality of possible destinations (30, 23, 33, 72) in a map section (31) on a display area (3). The control device (1) includes an input device (4). This input device is configured to receive a category selection signal (35). The category selection signal (35) corresponds to a user selection. Furthermore, the category selection signal (35) includes information about a selected category of possible primary destinations (32). The control device (1) also includes a controller (6). This controller is configured to generate a display signal (37) in response to the category selection signal. The display signal (37) causes the possible primary destinations (32) to be displayed in the map section (31). The display signal (37) corresponds to the information of the selected category.Furthermore, the display signal also causes a display of secondary targets (33) of at least one other category in the map section (31), whereby the display of the primary targets (32) of the selected category differs from the display of the secondary targets (33) of the other category.
