Person-Targeted Information Device Using Video Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information systems in public and commercial buildings often send global alarm signals to all individuals, regardless of their location, which is inefficient and does not provide targeted feedback to individuals, and they lack the ability to selectively direct information signals to specific persons or objects based on their position and behavior.
Innovation Solution
An information device equipped with a surveillance camera and an evaluation device that uses digital image processing and video content analysis to detect and track individuals, activating output devices such as visual or acoustic signals to provide location-specific and person-specific information, allowing for selective communication of navigation, warnings, or advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If global alarm signals are sent to all individuals in monitored areas, then information coverage is ensured, but information efficiency deteriorates and resource waste increases
Solution Approach 1:
The system segments the monitored area into multiple zones and segments information delivery by targeting specific individuals or groups rather than broadcasting to all persons. The surveillance camera system divides the overall monitored space into detectable regions, and the evaluation device segments information delivery based on detected person positions and behaviors, sending information signals only to relevant segments rather than the entire area.
Solution Approach 2:
The system applies local quality by providing different information signals to different locations and individuals within the monitored area. Instead of uniform global broadcasting, the evaluation device determines which specific persons receive information based on their position, behavior, and relevance to the detected event, creating localized information delivery with varying content and timing for different spatial locations.
2Reliability
If surveillance personnel manually monitor and respond to all events, then comprehensive monitoring is achieved, but operational complexity and time consumption increase
Solution Approach 1:
The system implements self-service by enabling automatic detection and response through the evaluation device that processes surveillance camera data and automatically sends information signals to detected persons. The system serves itself by automating the monitoring and communication functions that would otherwise require manual surveillance personnel intervention, with the evaluation device independently analyzing video content and triggering appropriate information delivery without human intermediation.
Solution Approach 2:
The system establishes feedback loops where the surveillance camera continuously monitors the area, the evaluation device analyzes the video content to detect persons and their positions, and information signals are automatically sent back to the detected persons based on their location and behavior. This closed-loop feedback system enables automatic response to detected events, eliminating the need for manual surveillance personnel to continuously monitor and respond to all events.
3Measurement precision
If selective information delivery to specific persons is implemented, then information precision is improved, but system complexity increases
Solution Approach 1:
The system achieves universality by using a multi-functional evaluation device that combines video content analysis, person detection, position determination, and information signal routing capabilities in a single integrated unit. The surveillance camera system serves multiple purposes including area monitoring, person detection, and position tracking. This multi-functionality reduces the need for separate specialized devices for each function, thereby limiting the increase in system complexity while maintaining selective information delivery precision.
