Map-Based Multi-Camera Dashboard for Spatial Event Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems with multiple camera views present streams in a grid-like interface, making it difficult for security personnel to identify important information and the relative positions of cameras, leading to delays in addressing security issues.
Innovation Solution
A map-based multi-camera dashboard that positions camera windows according to their real-life locations, with additional security information and a heat map to highlight high-activity areas, allowing immediate identification of security events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a grid-like user interface is used to display multiple camera streams, then all camera views can be presented simultaneously, but security personnel cannot immediately identify windows showing important information and cannot easily identify camera positions relative to one another
Solution Approach 1:
The patent creates a visual copy of the physical environment layout on the user interface. A map or floor plan is displayed that replicates the spatial arrangement of the monitored areas, and camera windows are positioned on this map at locations corresponding to their actual physical positions. This allows security personnel to immediately understand where each camera is located without needing to interpret grid coordinates or camera labels.
Solution Approach 2:
Different regions of the user interface are assigned different functions based on their spatial correspondence to the physical environment. Specific areas on the map can be highlighted or given different visual properties to indicate security events, high-activity zones, or areas of concern. This allows important information to be immediately identified through local visual characteristics rather than requiring uniform treatment of all camera views.
2Productivity
If a grid-like user interface is used to display multiple camera streams, then all camera views can be presented simultaneously, but security personnel experience delay in addressing security issues
Solution Approach 1:
The patent employs color changes and visual highlighting to draw attention to security events and high-activity areas. When a security event is detected or an area shows high activity, the corresponding region on the map and its associated camera window are highlighted with distinct colors or visual indicators. This allows security personnel to immediately identify areas requiring attention without manually scanning all camera views, significantly reducing response time.
3Loss of information
If camera windows are arranged according to physical positions, then spatial context is preserved and camera locations are easily identified, but the user interface layout becomes more complex
Solution Approach 1:
The map or floor plan displayed on the user interface serves multiple functions simultaneously: it provides the spatial framework for positioning camera windows, acts as a legend identifying different areas of the environment, highlights security events and high-activity zones, and serves as a navigation aid. This multi-functionality reduces the need for separate interface elements and simplifies the overall design despite the customized layout.

AI summary
Example implementations include a method, apparatus and computer-readable medium for controlling multi-camera view user interface, comprising generating, for a graphical user interface, a respective camera window for each respective camera of the plurality of cameras in different areas of an environment, wherein the respective camera window outputs a stream captured by the respective camera. The implementations further include arranging the graphical user interface according to a camera window placement scheme based on a layout of the environment. Additionally, the implementations further include generating, for display, a dashboard comprising the graphical user interface organized according to the camera window placement scheme.
