Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle and system user interfaces present cognitive bottlenecks, diverting operators' attention from critical tasks due to complex and static information layouts, which can lead to safety issues in attention-intensive environments.
Innovation Solution
A cognitively optimized user interface that uses a hierarchical display of vehicle or system status datums, prioritizing the most critical information based on current operational context, allowing operators to quickly focus on essential data without unnecessary distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a comprehensive user interface displays all vehicle status information, then information completeness is improved, but operator attention is diverted from critical tasks
Solution Approach 1:
The user interface is segmented into multiple hierarchical levels: a primary display showing only critical safety-related information (speed, warning lights), a secondary display for routine vehicle status (fuel, temperature), and a tertiary display for detailed diagnostics. This segmentation allows operators to access comprehensive information only when needed, reducing unnecessary attention diversion while maintaining information availability.
Solution Approach 2:
Different regions of the user interface are assigned different information densities and priority levels. Critical safety information is placed in high-visibility areas with simple, immediate recognition formats, while less critical information is placed in lower-priority regions. This local differentiation allows operators to quickly identify critical issues without being overwhelmed by comprehensive data.
2Device complexity
If a static dashboard layout is used, then device simplicity is improved, but information accessibility is worsened
Solution Approach 1:
The dashboard layout transitions from static to dynamic, automatically reconfiguring based on operational context. During normal driving, only essential information is displayed. When fault conditions are detected, the interface dynamically expands to show relevant diagnostic information. This dynamic adaptation maintains simplicity during routine operation while providing comprehensive information when needed, improving both accessibility and operational ease.
Solution Approach 2:
The user interface is designed as a multi-functional system that can display different types of information in different formats depending on the situation. The same display hardware serves multiple purposes: critical alerts, routine status monitoring, diagnostic information, and guidance. This universality allows a single simplified interface to replace multiple specialized displays, maintaining device simplicity while improving information accessibility.
3Loss of information
If multiple information sources are integrated, then information completeness is improved, but cognitive load is increased
Solution Approach 1:
The system extracts and separates critical information from the comprehensive data stream. Rather than presenting all integrated information sources simultaneously, the interface extracts only the most critical elements (safety warnings, immediate status indicators) for primary display. Less critical information is made available through secondary interfaces or on-demand, reducing cognitive load while maintaining access to complete information when needed.
Solution Approach 2:
The user interface changes the parameters of information presentation based on operational context. During normal operation, information is presented in simplified formats with lower detail levels. When faults or critical conditions are detected, the system changes parameters to provide more detailed, comprehensive information. This adaptive parameter adjustment reduces cognitive load during routine operation while providing complete information when necessary.
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.
