Unified Media Interface for In-Vehicle Driver Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle user interfaces for multi-source media players are text-based and sequential, making it difficult for drivers to navigate and discover audio content quickly, especially when multiple sources like satellite and IP streaming are involved, as they require attention and eye glances away from the road.
Innovation Solution
A graphical user interface that unifies content presentation from multiple sources using tile, icon, and album art-based layouts, allowing users to interact through touch screens, voice commands, and haptic devices, enabling efficient navigation and content discovery without focusing on text-based lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text-based sequential channel listings are used to present media content, then comprehensive content information is provided, but navigation complexity and driver attention demand increase
Solution Approach 1:
The patent segments the media content presentation into visual categories (music, news, sports, talk) represented by distinct icons and tiles rather than sequential text listings. Each category is visually segmented and can be independently accessed, allowing drivers to quickly identify and select content types without navigating through lengthy text channels.
Solution Approach 2:
The patent transitions from one-dimensional sequential text listings to a two-dimensional visual interface with icons, tiles, and graphical representations. This dimensional change allows multiple content categories to be displayed simultaneously in a grid layout, enabling parallel scanning and selection rather than sequential reading.
2Device complexity
If multiple media sources (satellite, IP streaming, broadcast) are completely segregated, then each source can be managed independently, but content selection flexibility and user experience deteriorate
Solution Approach 1:
The patent merges multiple segregated media sources (satellite radio, IP streaming, broadcast radio) into a unified content library accessible through a single interface. The visual category system consolidates content from all sources under common headings like Music, News, Sports, and Talk, allowing seamless mixing and matching of content regardless of source origin.
Solution Approach 2:
The patent creates a universal interface that handles multiple media sources through a single unified system. The same visual category tiles and icon-based navigation work across all content types and sources, providing a multi-functional platform that adapts to different media formats without requiring separate control schemes.
3Loss of information
If detailed text-based channel information is displayed, then complete content metadata is available, but driver distraction and eye glance duration increase
Solution Approach 1:
The patent uses color-coded visual indicators to convey content information quickly. Different colors represent different categories (music, news, sports, talk) and states (live, on-demand, source type), allowing drivers to grasp content metadata at a glance without reading detailed text descriptions. Visual color cues replace lengthy text information.
Solution Approach 2:
The patent extracts essential content information (category type, source, availability status) and presents it through concise visual icons and symbols rather than detailed text. Only the most critical metadata is visually represented, while comprehensive information remains accessible through selection but is not displayed in full to avoid distraction.
Data Source
AI summary
A graphical user-interface for a multi-source media player that optimizes the presentation of content and navigational choices to a user, as well as the user's interactive experience, is described. Methods of enabling users to access, manage and listen to content, whether delivered over an IP, satellite, other communications channel, or some/all of such channels, are presented. The user-interface can include, for example, tile, icon and album art-based user-interface elements. The user-interface elements may be selected via touch screen, voice commands, trackball and remote touch activated panels, as well as haptic devices or rotary controllers, or various multi-modal combinations of inputs and control signals.
