Navigation Device Character Icon Selection Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices face challenges in allowing users to easily select information matched with their preferences from a large number of stores and facilities without increasing operational complexity, often leading to discomfort or loss of intended experience due to automatic preference analysis.
Innovation Solution
A navigation device that displays symbols featuring individualities on a screen, allowing users to select sightseeing information based on the individuality of chosen symbols, enabling quick selection of information according to user intention without requiring clear criteria like genre or price, and providing intuitive operation with varied screen designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic preference analysis is used to select stores and facilities, then the device can operate according to user preference, but user discomfort increases and user intention may be overridden
Solution Approach 1:
The patent introduces a character selection interface as an intermediary between the user and the preference analysis system. Users select from multiple character icons, each representing different preference types. This intermediary layer allows users to consciously control the preference analysis process while still benefiting from automated selection, thereby maintaining user comfort and intention.
2Measurement precision
If clear and standardized benchmarks (genre, store name, price) are required for selection, then selection precision improves, but user operation complexity increases
Solution Approach 1:
The patent changes the selection parameters from detailed, standardized benchmarks (genre, store name, price) to simple character icons representing preference types. This parameter transformation maintains selection precision by capturing essential user preferences while dramatically reducing operation complexity, as users only need to select a character icon rather than specify multiple detailed criteria.
3Measurement precision
If self-analysis and input of user preference by the user is implemented, then preference accuracy improves, but operational burden increases and operability is lost
Solution Approach 1:
The patent implements preliminary action by pre-defining multiple character icons that represent different preference types. Instead of requiring users to perform self-analysis and input their preferences from scratch, the system provides pre-prepared preference categories in the form of character icons. Users simply need to select from these pre-defined options, which maintains preference accuracy while preserving operability.

AI summary
A navigation device that can easily select information matched with user's favorite or intention from information on many stores and facilities is provided. In a car navigation device 1 for performing a route guidance of a moving object, plural symbols featured by individualities are displayed on a display panel 2, and when any one of the plural displayed symbols is selected, sightseeing information relevant to the individuality of the selected symbol is selected from the sightseeing facilities data base 31, and the selected sightseeing information is displayed on the display panel 2.
