Remote Expert UI View Selection for Prioritized Imaging Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The multitasking environment for remote experts assisting multiple imaging bays can be taxing, requiring efficient event prioritization and view selection to provide effective assistance to local operators.
Innovation Solution
A system with a feed aggregator that analyzes signal feeds from local operators' workspaces, identifies the highest priority event using event prioritization and mapping, and selects the appropriate UI view to present relevant information to the remote expert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the remote expert manually switches between multiple UI views to monitor multiple imaging bays, then the expert can provide assistance to multiple sites, but the cognitive load and time required to manage multiple views increases significantly
Solution Approach 1:
The system pre-configures multiple UI views (enterprise view, site view, room view) and automatically selects and switches between them based on detected events. This eliminates the need for the remote expert to manually switch views, as the system has already prepared the appropriate views and automatically transitions between them based on event priority and type.
Solution Approach 2:
The remote workstation automatically monitors signal feeds, detects events, determines priority levels, and switches UI views without human intervention. The system serves itself by autonomously managing the complexity of multiple views, allowing the remote expert to focus on assistance rather than view management.
2Loss of information
If the remote workstation displays all available information from multiple imaging bays simultaneously, then the remote expert has complete information, but the interface becomes overwhelming and difficult to navigate
Solution Approach 1:
The information is segmented into three distinct UI views: enterprise view (macro-level site distribution), site view (intermediate-level site overview), and room view (detailed-level single bay information). Each view presents a specific portion of the total information set, allowing the remote expert to access complete information through systematic navigation between segmented views rather than overwhelming simultaneous display.
Solution Approach 2:
The UI dynamically switches between different views based on detected events and their priority levels. The system adapts the displayed information in real-time, transitioning from enterprise view to site view to room view as events require more detailed attention. This dynamic adaptation maintains ease of operation by only displaying relevant information at each moment while preserving access to complete information through view transitions.
3Speed
If the system automatically switches UI views based on detected events, then the remote expert receives timely information about urgent situations, but the system must accurately prioritize and interpret multiple event types
Solution Approach 1:
The system pre-establishes an event prioritization mapping that assigns priority levels and corresponding UI views to different event types before runtime. This mapping is stored in memory and readily accessible during operation, allowing the system to quickly lookup and respond to events without complex real-time decision-making. The prioritization logic is prepared in advance, enabling fast response to urgent events.
Solution Approach 2:
The event prioritization mapping acts as an intermediary between event detection and UI view selection. Rather than directly complex logic connecting events to views, the mapping serves as a lookup table that translates event types into priority levels and appropriate views. This intermediary structure simplifies the system's decision-making process while maintaining accurate event response.

AI summary
A method (100) of controlling a user interface (UI) provided by a remote operator workstation of a remote expert (RE) providing assistance to local operators (LO) of respective medical imaging devices (2) during a medical imaging examination includes: analyzing signal feeds (17, 18, 9) received by a feed aggregator (15) to detect events occurring in workspaces of the local operators; identifying a highest priority event from amongst the detected events using an event prioritization mapping; identifying a highest priority local operator as the local operator in whose workspace the highest priority event occurred; selecting a highest priority UI view corresponding to the highest priority event using the event-to-UI view mapping; and presenting information derived from the signal feeds from the workspace of the highest priority local operator in accordance with the highest priority UI view.
