Adaptive Heads-Up Display Message Prioritization for Driver Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heads-up displays lack effective methods to adaptively control and prioritize information display based on user attention and interest, leading to potential distraction and resource inefficiency.
Innovation Solution
An adaptive heads-up display system that utilizes a user monitoring system and a remote system to filter and prioritize display requests using user attention data, behavior history, and predictive models, ensuring only high-priority information is shown, with options for haptic and auditory feedback for safety-related messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple messages are displayed on the heads-up display simultaneously, then information completeness is improved, but driver distraction increases
Solution Approach 1:
The system dynamically changes display parameters (visibility, priority levels, timing) based on user attention state and message urgency. Messages are assigned different display priorities and timing based on real-time analysis of driver attention from the user monitoring system, allowing multiple messages to be managed without overwhelming the driver simultaneously
Solution Approach 2:
The arbitration gateway automatically filters and prioritizes messages without requiring driver intervention. The system self-regulates message display based on predefined priority rules and real-time user attention data, eliminating the need for the driver to manually manage or select among multiple displayed messages
2Loss of information
If all display requests from operational applications are shown, then information availability is improved, but system resource efficiency deteriorates
Solution Approach 1:
The arbitration gateway extracts and filters out low-priority messages from the pool of display requests based on user attention state and predefined priority rules. Only the most relevant messages are selected for display, eliminating unnecessary processing and rendering of low-priority content while maintaining availability of critical information
Solution Approach 2:
The system dynamically adjusts message display parameters including visibility, timing, and priority based on real-time user attention data. This allows the system to optimize resource allocation by displaying only necessary messages at appropriate times, reducing overall system resource consumption while maintaining information availability when needed

AI summary
Methods and systems for a vehicle for adaptively controlling messages displayed on a heads-up display. A plurality of requests is received by a first controller to display a message associated with each of the plurality of requests on a heads-up display from one or more operational applications. The plurality of requests are filtered by an arbitration gateway based on user attention data gathered from a user monitoring system and a user behavior history. A priority is assigned to each of the plurality of filtered requests based on a user interest prediction model, at least a portion of the plurality of the filtered requests are selected based on the assigned priority, and the messages associated with the selected portion of the plurality of filtered requests are displayed on the heads-up display.
