Cognitive UI for Motor Vehicles Using Dynamic Hierarchical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle user interfaces present vehicle status information in a way that creates cognitive bottlenecks, requiring drivers to divert their attention from the road for extended periods, as they often feature static layouts that slow down perception and understanding of critical information.
Innovation Solution
A cognitively optimized user interface that uses a hierarchical display of vehicle status datums, prioritized based on current operational context, to minimize the time drivers need to focus on the user interface, featuring a processor, sensor interface, and memory to dynamically organize and present information on a display, such as an OLED or LCD, aligning with how humans process visual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a static layout is used to present vehicle status information, then the device complexity is reduced, but the time required for perception and processing of visual information increases
Solution Approach 1:
The patent implements a dynamic display system that automatically reorganizes vehicle status information based on contextual parameters such as driving conditions, vehicle state, and driver behavior patterns. The interface transitions from static to dynamic layout, where information elements are continuously repositioned and reprioritized to match current operational context, thereby reducing perception time without requiring complex manual configuration
Solution Approach 2:
The system pre-organizes information hierarchies based on anticipated driving scenarios and vehicle states. By preparing and pre-positioning critical information elements according to predicted contextual needs, the system reduces the time required for information processing when the driver needs to access vehicle status, as the layout is already optimized before the driver actually needs to perceive the information
2Loss of information
If more vehicle status information is displayed simultaneously, then the information completeness is improved, but the cognitive load on the driver increases
Solution Approach 1:
The patent segments vehicle status information into hierarchical groups based on relevance to current driving context. Critical safety-related information is separated and prioritized in the visual hierarchy, while less critical information is organized in secondary groups. This segmentation allows complete information to be displayed while maintaining low cognitive load through structured organization that matches human perceptual processing patterns
Solution Approach 2:
Different regions of the display are assigned different information densities and visual prominence levels based on their importance. High-priority information receives enhanced visual properties (brightness, size, position) while maintaining local optimization for each information type. This allows comprehensive information display with varying levels of visual emphasis that reduces overall cognitive processing requirements
3Loss of information
If the driver shifts attention to the user interface to process vehicle status information, then the information perception is improved, but the attention to the road decreases
Solution Approach 1:
The system updates and refreshes the display information at optimized intervals rather than continuously, synchronizing information updates with driver attention cycles and driving conditions. Critical information is refreshed more frequently while less critical information updates periodically, reducing visual clutter and attention demands while maintaining adequate information perception for safe operation
Solution Approach 2:
The patent employs color coding and visual property changes to encode information priority and state. Critical alerts and warnings use distinctive colors and visual properties that capture driver attention immediately without requiring sustained focus, while normal status information uses subdued visual properties. This allows effective information communication with minimal attention diversion from the road
Data Source
AI summary
An apparatus for providing a rapidly perceivable display of vehicular data includes a processor, a sensor interface, a device display, and a memory. The memory contains instructions, which, when executed by the processor, cause the apparatus to obtain, via the sensor interface, vehicle data, determine, based on the vehicle data, a plurality of status datums, determine, for each status datum of the plurality of status datums, a current priority value, and display, on the device display, a hierarchical array. In at least one embodiment, the hierarchical array presents a set of status datums determined to have the highest current priority values of the plurality of status datums. In at least one embodiment, each status datum of the hierarchical array occupies a location in the hierarchical array corresponding to its current priority value.
