Dual-Screen Navigation Interface for Vehicle Turn Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems in vehicles and mobile devices have limitations, with in-car systems providing a limited experience compared to mobile devices, and interacting with mapping applications on small mobile device screens is difficult while driving.
Innovation Solution
An integrated mapping and navigation application that generates simultaneous user interfaces for both mobile devices and vehicle screens, adapting to different screen types and capabilities, allowing for different interaction methods based on touchscreen quality and availability, and providing features like predictive routing and turn-by-turn navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mapping application is used on a mobile device, then the navigation experience is robust and feature-rich, but the small screen size makes interaction difficult while driving
Solution Approach 1:
The patent combines the robust mapping application from the mobile device with the large display and vehicle integration capabilities of the in-car system. The application runs on the mobile device but outputs its user interface to the vehicle's display screen, merging the computational power and navigation features of the mobile device with the display advantages of the vehicle system.
Solution Approach 2:
The mobile device acts as an intermediary between the driver and the vehicle's navigation system. Instead of directly interacting with the vehicle's limited navigation controls, the driver interacts with the familiar mobile device application interface, which then communicates with the vehicle system for display and potential vehicle control integration.
2Ease of operation
If an in-car navigation system is used, then the screen is larger and conveniently positioned, but the navigation experience is more limited compared to mobile devices
Solution Approach 1:
The mobile device runs a universal mapping application that can output to multiple types of displays (mobile device screen, vehicle display screen, or both simultaneously). The application adapts its interface based on the output device capabilities, providing a consistent navigation experience across different platforms while leveraging the unique strengths of each device.
3Adaptability or versatility
If the mapping application outputs different user interfaces for different vehicle screen types, then the interface compatibility is improved, but the system complexity increases
Solution Approach 1:
The mapping application dynamically changes its output parameters based on the detected vehicle display capabilities. It identifies the type of display screen (high-quality touchscreen, low-quality touchscreen, or non-touchscreen) and automatically adjusts the user interface characteristics, such as touch responsiveness and control methods, to match the capabilities of the target display device.

AI summary
Some embodiments provide a method for an application executing on a mobile device. The method renders an animated navigation presentation for output to an external display screen not part of the mobile device. The navigation presentation includes an animated map showing at least a portion of a route to a destination. The method simultaneously displays information regarding a maneuver along the route on a display screen of the mobile device without displaying a same animated map on the mobile device. In some embodiments, the displayed information regarding the maneuver comprises a graphical instruction and a text instruction for a next maneuver along the route.
