Navigation System Gesture Region Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems require users to make precise entries for alternative routes, diverting attention from driving and potentially leading to unfavorable route selections, as they need to specify exact points or complex inputs to avoid congested areas or preferred regions.
Innovation Solution
A method allowing users to input preferred regions via intuitive gestures on a touchscreen or touchpad, such as sliding movements, which are translated into route sections on a digital map, enabling the calculation of optimal alternative routes without exact coordinate entry, focusing on travel time, energy consumption, or other cost parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users input exact route points or complex entries to specify preferred regions, then route determination precision is improved, but driver attention is diverted and operation complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the system automatically interprets the driver's rough gesture input (swiping movement) and converts it into precise route determination parameters. The gesture recognition system acts as a mediator between the driver's intent and the navigation system's route calculation, eliminating the need for the driver to manually input exact coordinates while maintaining high precision in route determination.
Solution Approach 2:
The system performs self-service by automatically calculating and adjusting the route based on the driver's gesture input without requiring manual coordination. The navigation system independently processes the gesture data, determines the preferred region, and reculates the optimal route, freeing the driver from complex operational tasks while maintaining accurate route determination.
2Measurement precision
If users make precise entries for alternative routes, then route selection accuracy is improved, but operation time and complexity increase
Solution Approach 1:
The system performs preliminary action by pre-processing the gesture input and pre-calculating the preferred region before the driver completes the swiping movement. The system anticipates the driver's intent and begins route calculation in advance, reducing the total operation time while maintaining high route selection accuracy through pre-computed route options.
Solution Approach 2:
The system skips the time-consuming step of manual coordinate input by directly interpreting the gesture's essential information (direction and rough area). Instead of requiring the driver to precisely mark every point, the system rushes through the route determination process by using the gesture's overall trajectory to quickly identify the preferred region and calculate alternative routes.
3Productivity
If navigation systems automatically calculate alternative routes, then route optimization is improved, but user control over preferred regions is reduced
Solution Approach 1:
The system implements feedback by continuously monitoring the driver's gesture input and adjusting the route calculation accordingly. The driver's swiping movement provides real-time feedback about the preferred region, and the system responds by optimizing routes that respect this preference. This closed-loop approach maintains user control while achieving automated route optimization.
Solution Approach 2:
The system applies dynamics by making the route determination process adaptive and flexible rather than static. The gesture recognition system dynamically interprets the driver's intent based on the swiping movement's characteristics (direction, length, speed), and the route calculation dynamically adjusts to accommodate the preferred region. This dynamic approach preserves user control while enabling automated optimization.

AI summary
The invention relates to a method for determining a preferred route (214) between a starting point and a destination. Said method comprises: a step of detecting, by y user, an intermediate destination input relating to a digital map (200), said intermediate destination input representing a desire of the user to drive through a preferred region displayed in the digital map (200) between the starting point and the destination; a step of assigning the intermediate destination input to a road network region (212) underlying the preferred region in the digital map (200); and a step of using at least one route segment (216) contained in the road network region (212) in a process for determining a route between the starting point and the destination in order to determine the preferred route (214).
