In-Vehicle Media Interface for Mobile Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle users face challenges in accessing and controlling media files on mobile devices while driving, due to the device's inaccessibility and the prohibition on operating mobile devices while operating a vehicle, necessitating a solution for navigating and playing media files through a vehicle computing device.
Innovation Solution
A system and method that determines the location of media files on a mobile device, links the vehicle computing device with the mobile device, and provides an in-vehicle user interface to navigate and play media files, using unique identifiers and voice recognition, allowing for wireless control of portable audio devices via an AVRCP protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile device is made inaccessible while driving, then safety is improved, but media file accessibility deteriorates
Solution Approach 1:
The vehicle computing device serves as an intermediary between the driver and the mobile device. It provides a user interface through the vehicle's audio system and display that mirrors the mobile device's media library and navigation capabilities, allowing the driver to access media files without physically interacting with the mobile device while driving.
Solution Approach 2:
The system creates a virtual copy of the mobile device's media library and navigation interface within the vehicle computing device. The in-vehicle user interface replicates the functionality of the mobile device's media player and file system, allowing access to media files through the vehicle's existing audio and display systems without requiring direct access to the mobile device.
2Object-affected harmful factors
If the mobile device is stowed away in a pocket or purse, then driving safety is improved, but media file accessibility deteriorates
Solution Approach 1:
The vehicle computing device acts as an intermediary that maintains a persistent connection to the mobile device's media library. Once linked, the system can quickly navigate to and play media files without requiring the driver to physically retrieve or access the mobile device, significantly reducing access time while maintaining safety.
Solution Approach 2:
The system performs preliminary indexing and organization of media files from the mobile device into the vehicle computing device's storage. This pre-processing allows the system to quickly locate and play media files without needing to scan through the entire mobile device library in real-time, reducing access time when the driver wants to play media.
3Ease of operation
If the vehicle computing device indexes the mobile device, then media file accessibility is improved, but device complexity increases
Solution Approach 1:
The vehicle computing device leverages its existing multi-functional capabilities to handle media indexing and playback. The same processing units, storage systems, and user interface components used for other vehicle functions (navigation, audio processing, display control) are also utilized for indexing and playing media from the mobile device, avoiding the need for dedicated hardware and reducing overall system complexity.

AI summary
Systems and methods for browsing a mobile device are provided. Some embodiments may include determining a location of each of a plurality of media files on the mobile device. The plurality of media files may be organized according to a predetermined configuration and may include at least two identical media files at different locations in the predetermined configuration. Similarly, some embodiments may include receiving a request for a requested media file of the plurality of media files at the vehicle computing device and determining which of the at least two identical media files is more accessible. Still some embodiments may include navigating the mobile device to one of the at least two identical media files that is more accessible and play the requested media file through a vehicle audio system.
