Adaptive Navigation Interface for Vehicle Display and Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems, both in portable media devices and in-car systems, face challenges in providing an effective and user-friendly interface for drivers due to the limitations of screen size and interaction methods, particularly when navigating through complex routes and destinations.
Innovation Solution
A mapping and navigation application that generates multiple user interfaces tailored for different devices and vehicle systems, including smartphones, tablets, and in-car displays, with adaptive user interfaces for high-quality touchscreens, low-quality touchscreens, and non-touchscreens, allowing for voice interaction and gesture recognition, and providing predictive routing and turn-by-turn navigation features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mapping application provides comprehensive navigation features on portable media devices, then navigation functionality is improved, but screen size and interaction limitations reduce user experience
Solution Approach 1:
The mapping application implements multi-functionality by supporting multiple output targets (portable media device screen and vehicle display screen) simultaneously. The application can generate and display navigation interfaces on both the portable device's limited screen and the vehicle's larger display, allowing the system to adapt to different screen sizes and interaction capabilities while providing comprehensive navigation features.
2Area of stationary object
If in-car navigation systems use larger screens, then display quality is improved, but interaction capabilities are limited compared to mobile devices
Solution Approach 1:
The application segments the interaction model by implementing different interaction handlers for different display contexts. The vehicle interface can be controlled through multiple input methods including voice commands, vehicle-mounted controls, and portable device touchscreen gestures, while the portable device maintains its full touchscreen interaction capabilities. This segmentation allows each interface to be optimized for its specific context while maintaining overall system functionality.
3Adaptability or versatility
If the application generates multiple user interfaces for different devices, then adaptability is improved, but system complexity increases
Solution Approach 1:
The application uses an intermediary architecture where a central mapping application generates interface definitions that are then adapted for different output targets. The system mediates between the core navigation functionality and the diverse interface requirements by using a standardized interface generation mechanism that can output to multiple devices simultaneously, reducing the complexity that would otherwise arise from implementing separate applications for each device type.
4Loss of information
If navigation information is displayed on both portable device and vehicle display, then information availability is improved, but driver distraction risk increases
Solution Approach 1:
The application implements local quality by displaying different types of navigation information on different displays based on their appropriate use cases. The vehicle display shows large-scale map views and upcoming maneuver information that are useful for the driver's forward-looking needs, while the portable device displays detailed turn-by-turn instructions and menu options that require focused attention. This differentiation reduces driver distraction by placing each type of information on the display where it is most appropriate.

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.
