Touch Map Display Mode Switching for Facility Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require complex operations to select and display different facility types on a map, which is cumbersome for drivers and unsafe during navigation.
Innovation Solution
An information display device that switches between a first and second display mode based on intuitive touch operations, such as swipes, to highlight and display target objects of a specific type while hiding others, using a processing unit to detect operations and generate screen information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user selects and inputs facility type icons to be displayed on the map, then the user can display specific facility types, but the setting operation becomes complicated and time-consuming
Solution Approach 1:
The system automatically detects the user's gaze direction and displays facility icons corresponding to the viewed area without requiring manual selection. The facility display unit displays icons based on the detected gaze position, allowing the system to serve itself rather than requiring the user to manually configure each facility type.
Solution Approach 2:
The patent replaces the manual mechanical interaction of selecting and inputting facility type icons with an automatic optical detection system. The gaze detecting unit uses camera-based eye tracking to substitute the manual selection process, transforming the interaction from mechanical touch input to automatic optical detection and interpretation.
2Quantity of substance
If multiple facility type icons are displayed on the map, then the user can see various facilities, but the display becomes cluttered and harder to see
Solution Approach 1:
The system displays facility icons selectively based on the user's gaze position rather than uniformly across the entire map. Icons are displayed in the specific regional area corresponding to where the user is looking, creating local visibility rather than global clutter. This ensures that only relevant facilities are visible at any given moment.
Solution Approach 2:
Instead of displaying all available facility icons simultaneously, the system displays only a partial set corresponding to the currently viewed area. This partial display action prevents information overload while maintaining the ability to access complete information when needed by shifting the gaze to different areas.
3Device complexity
If the user has to select a facility type each time a different icon is desired, then the system maintains simplicity, but the operation time increases
Solution Approach 1:
The system maintains continuous display of facility icons corresponding to the user's current gaze position without requiring intermittent selection actions. As the user moves their gaze, the displayed icons update continuously to match the new viewing area, eliminating the need to stop and manually select different facility types between viewing different areas.
Solution Approach 2:
The patent introduces dynamic adaptation where the displayed facility icons automatically adjust based on the user's real-time gaze position. The system transitions from a static display requiring manual reconfiguration to a dynamic display that automatically reconfigures itself based on user attention, reducing operation time while maintaining simplicity.

AI summary
An information display device comprises: an operation detecting unit for detecting a touch operation on a touch panel; an object information acquiring unit for acquiring information on objects within a predetermined search range; and a display information generating unit for generating screen information to be displayed in a display area, wherein the display information generating unit generates screen information for display in a first mode in which a plurality of types of objects are arranged around the position of the terminal itself, the object information acquiring unit acquires information on a target object that is associated with a predetermined touch operation when the operation detecting unit detects a predetermined touch operation, and the display information generating unit generates information for display in a second display mode in which information on the target object is arranged around the terminal and information on objects other than the target object is hidden.
