Geographic Video Display for First Responders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
First responders do not effectively utilize video feeds due to them being perceived as distracting, hindering their ability to focus on tasks at hand.
Innovation Solution
A method and apparatus for displaying real-time video on geographically accurate displays, allowing first responders to easily assess situations by matching cardinal coordinates of video feeds with display devices, mimicking the use of rear-view and side-view mirrors for non-distractive information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video feeds are displayed to first responders, then situation assessment capability is improved, but distraction and reduced focus occur
Solution Approach 1:
The video feed is segmented and displayed only on specific displays corresponding to the cardinal directions where events are detected, rather than displaying on all displays. This selective segmentation reduces unnecessary information presentation and minimizes distraction while maintaining situational awareness capability.
Solution Approach 2:
Different displays are assigned different qualities based on their spatial relationship to the event. Displays in the direction of the event receive video feeds with higher priority and detail, while displays in other directions receive reduced or no video information. This local differentiation ensures that first responders receive detailed information only where needed, reducing overall distraction.
2Loss of information
If multiple displays are used to show video feeds from different cameras, then situational awareness is improved, but complexity of the display system increases
Solution Approach 1:
The display system uses existing displays already present in the first responder's environment (such as monitors in a vehicle or on equipment) rather than requiring dedicated new displays. These universal displays serve both their original functions and the additional function of displaying directional video feeds, thereby reducing overall system complexity while maintaining comprehensive situational awareness.
Solution Approach 2:
The system automatically determines which displays should receive which video feeds based on the spatial relationship between cameras and displays, without requiring manual configuration or user intervention. This self-organizing behavior reduces operational complexity while ensuring comprehensive coverage of all situations through the display network.
3Measurement precision
If real-time video is displayed on displays, then detail of the situation is improved, but attention diversion from primary tasks occurs
Solution Approach 1:
Instead of continuously updating all displays with video feeds, the system updates video displays periodically or only when events are detected in specific cardinal directions. This periodic action maintains sufficient detail for situation assessment while reducing the continuous visual stimulus that would divert attention from primary tasks.
Solution Approach 2:
Rather than displaying video feeds on all displays regardless of event location, the system inverts the approach by displaying video feeds only on displays corresponding to the direction where events are detected. This inversion ensures that detailed visual information is provided only when and where it is most relevant, minimizing unnecessary attention diversion from primary tasks.

AI summary
A method and apparatus for displaying video is provided herein. During operation, video is displayed on one of many displays in a geographically correct fashion. For example, in an embodiment involving two displays (e.g., on a firefighter's two wrists), each of which display a video feed, the video is displayed such that the video feed of the most appropriate scene (not necessarily the video feed of the closest camera) is shown on that display.
