Adjustable Notification Display for UAM Ground Station HMI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in Urban Air Mobility (UAM) systems is the overwhelming amount of notification items for ground operators, which can lead to information overload and hinder effective mission management due to the lack of efficient filtering and prioritization mechanisms.
Innovation Solution
A notification item display system for UAM ground stations featuring a human-machine interface (HMI) with a controller that generates a graphical user interface (GUI) window, offering display prioritization options, allowing ground operators to select and prioritize notification items based on criticality, thereby filtering and presenting only essential information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all notification items are displayed to ground operators, then complete information is provided, but information overload occurs and operational efficiency decreases
Solution Approach 1:
The notification system is segmented into multiple priority levels (e.g., critical, high, medium, low). The controller divides the notification items and presents them in organized groups based on priority, allowing operators to systematically process important information first while maintaining access to complete information when needed.
Solution Approach 2:
The controller automatically performs preliminary sorting and prioritization of notification items before they reach the operator. Notification items are pre-categorized by priority level and source, so operators receive pre-processed, organized information rather than raw unsorted notifications, reducing cognitive load while maintaining information completeness.
2Reliability
If multiple notification items are displayed simultaneously, then comprehensive monitoring is achieved, but operator attention is overwhelmed
Solution Approach 1:
Different notification items are assigned different visual qualities and display characteristics based on their priority level. Critical notifications receive prominent display with distinctive visual indicators, while lower priority items are displayed with less visual emphasis. This allows comprehensive monitoring while guiding operator attention to the most important items first.
Solution Approach 2:
The controller acts as an intermediary between the notification sources and the operator. It filters, prioritizes, and organizes notifications before presentation, reducing the direct burden on the operator while maintaining comprehensive monitoring capability. The controller mediates the information flow to match operator capacity.
3Loss of information
If all notification sources are monitored, then complete situational awareness is achieved, but system complexity increases
Solution Approach 1:
The notification system is designed with universal processing capabilities that handle multiple notification sources (UTM service provider, ATC service provider, vertiport, fleet scheduler, weather service provider) through a single unified controller. The controller applies the same prioritization and display logic across all sources, reducing system complexity while maintaining comprehensive situational awareness.

AI summary
A display system for a UAM ground control station HMI, may include an HMI device and a controller for generating a graphical user interface (GUI) window for displaying notification items on the HMI device. The controller is configured to: receive a plurality of notification items for display at a UAM ground control station via the HMI device, provide, via a GUI widget displayed on the HMI device, a plurality of display prioritization options for identifying a different subset of the notification items for display in a notification item GUI window, receive selection via the GUI widget of a user-selected display prioritization option from the plurality of user-selectable display prioritization options, select a first set of notification items from the plurality of notification items for display based on the user-selected display prioritization option; and display the first set of notification items in the notification item GUI window on the HMI device.
