Optional Re-routing for Navigation Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional routing techniques in map navigation tools are inflexible and do not provide users with options for re-routing when they deviate from the predetermined route, failing to adapt to changes in the user's location during navigation.
Innovation Solution
Implementing a system that determines if a computing device is off a predetermined route and offers a re-route option, which can be selected via touch input on a touchscreen display, allowing users to recalculate a new route and automatically removing the option when the device returns to the original route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional routing techniques are used to provide predetermined routes, then route guidance is simple and straightforward, but the system lacks flexibility when users deviate from the route
Solution Approach 1:
The routing system dynamically adapts between predetermined routing mode and optional re-routing mode based on user deviation detection. The system transitions from a static predetermined route to a dynamic state where re-route options are offered, allowing the system to adjust its behavior based on real-time location data and user actions.
Solution Approach 2:
The system changes the routing parameter from strict adherence to a predetermined route to offering optional re-routing when deviation is detected. This parameter change allows the system to maintain simplicity for compliant users while providing flexibility for those who deviate, resolving the contradiction between route flexibility and system complexity.
2Measurement precision
If the system continuously monitors location to detect route deviation, then route accuracy is maintained, but energy consumption increases
Solution Approach 1:
The system performs location monitoring at a sufficient level to detect route deviation without continuous excessive checking. The monitoring is calibrated to trigger re-route options only when actual deviation occurs, rather than constantly updating and alerting, thus achieving adequate measurement precision while reducing unnecessary energy consumption.
3Ease of operation
If re-route options are always displayed to users, then user control over routing is maximized, but user interface clutter increases
Solution Approach 1:
The re-route option display is applied locally and conditionally - it appears only in the specific situation when a user deviates from the predetermined route. This localized application of the re-route option provides user control when needed without creating constant interface clutter, resolving the contradiction between ease of operation and interface complexity.
4Speed
If the system provides immediate re-routing when deviation is detected, then navigation responsiveness is improved, but unnecessary direction updates occur when users return to the original route
Solution Approach 1:
The system uses feedback from continuous location monitoring to determine whether to provide re-routing. When deviation is detected, re-route options are offered; when the user returns to the original route, the system detects this and removes the re-route options. This feedback mechanism ensures responsive navigation only when necessary, avoiding unnecessary computational waste.

AI summary
Disclosed herein are tools and techniques for providing optional re-routing. In one exemplary embodiment disclosed herein, a determination is made that a location of a computing device is not on a predetermined route between a start location and an end location. Based on the determining, a re-route option is provided. Also, while the re-route option is available, a determination is made that a subsequent location of the computing device is on the predetermined route, or a re-route is performed responsive to receiving a touch-anywhere input event on a touchscreen display.
