Touch Screen Vehicle Navigation Detour Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems provide limited interaction with users and do not allow for user-selected detour routes, relying solely on pre-provided information.
Innovation Solution
A vehicle navigation apparatus with a touch screen display and controller that enables users to draw a line on the screen to designate a detour route, determining if the drawn road is different from the original route and setting it as a detour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation system provides only pre-provided road guidance information, then the system complexity is reduced and ease of operation is improved, but user interaction capability and routing flexibility deteriorate
Solution Approach 1:
The navigation system allows users to independently draw detour routes on the touch screen display based on their own needs and preferences, rather than relying solely on pre-computed routes. This self-service approach enables users to create customized detour paths while the system automatically processes and implements these user-defined routes, thereby improving adaptability without significantly increasing system complexity
2Adaptability or versatility
If the navigation system allows users to draw detour routes on the touch screen, then user interaction capability and routing flexibility are improved, but device complexity and processing requirements increase
Solution Approach 1:
The controller serves as an intermediary that automatically processes the detour route drawn by the user on the touch screen. Instead of requiring complex user interface protocols or manual route configuration, the controller mediates between the simple act of drawing on the screen and the complex task of route calculation and navigation, thereby enabling routing flexibility without proportionally increasing device complexity
Solution Approach 2:
The system replaces traditional mechanical or manual route selection methods with a digital drawing interface on the touch screen. Users can visually draw detour routes directly on the displayed map, and the controller digitally processes this input to generate navigation instructions, eliminating the need for complex physical controls or manual route entry while maintaining routing flexibility

AI summary
A method of controlling a vehicle navigation apparatus included in a vehicle, and which includes displaying road guidance information on a touch screen display of the vehicle navigation apparatus and including a set travel route from a current position of a vehicle to a destination, determining, via a controller, whether a particular road displayed on the road guidance information has been drawn on, said particular road corresponding to a road that is different than a road included in the set travel route from the current position of the vehicle to the destination, and setting, via the controller, a road matched to the particular road that has been drawn on as a detour.
