Body-Worn Camera Physiological Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video and audio recording systems used by law enforcement, such as dash-cams and body cams, are limited in capturing events that occur outside their fixed or mobile perspectives, leading to inconsistencies and lack of credible evidence in interactions, particularly regarding excessive force allegations.
Innovation Solution
A system that analyzes video and audio data for physiological indicators, such as heart rate or speaking volume, to detect changes in individuals, providing real-time feedback to the officer and alerting operations control centers for potential escalating hostility or misconduct, using wearable devices and analytics modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video cameras are placed on fixed locations (dash-cams), then they can continuously record interactions, but they cannot capture events when officers depart from the patrol car
Solution Approach 1:
The patent transitions from static dash-cameras to dynamic body-worn cameras that move with the officer, enabling continuous coverage regardless of the officer's position. This dynamic placement ensures both reliability of evidence and adaptability to various interaction scenarios.
Solution Approach 2:
The body-worn camera acts as an intermediary device worn by the officer, capturing events from the officer's perspective rather than from a fixed vehicle location. This intermediary position allows simultaneous achievement of continuous recording and mobile coverage.
2Adaptability or versatility
If body cams are deployed to capture more events, then coverage of interactions improves, but the systems remain passive and cannot detect escalating situations
Solution Approach 1:
The system incorporates physiological sensing capabilities that provide real-time feedback about the subject's emotional and physiological state. This feedback mechanism transforms the passive recording system into an active detection system that can identify escalating situations through changes in heart rate, respiration, and other physiological indicators.
Solution Approach 2:
The body-worn system is enhanced to perform multiple functions: video recording, audio recording, and physiological indicator detection. This multi-functional approach maintains event coverage while adding the capability to detect subtle changes in physiological states that indicate escalating hostility.
3Reliability
If real-time analysis of physiological indicators is implemented, then early detection of escalating hostility is achieved, but system complexity increases
Solution Approach 1:
The system replaces complex manual analysis with automated computational algorithms that process physiological data. This substitution of mechanical/human analysis with electronic processing achieves reliable early detection while managing system complexity through software-based solutions.
Solution Approach 2:
The analytics system performs self-service by automatically detecting and analyzing physiological indicators without requiring constant human intervention. The system autonomously processes sensor data, identifies patterns indicating escalation, and generates alerts, reducing the operational complexity burden.
Data Source
AI summary
Systems and methods which detect in video and/or audio data a change in a physiological indicator of a person captured by the video and/or audio data, and which provide feedback indicating when the change in the physiological indicator occurs, are described. A method uses an analytics module operating on at least one processor. Data is received from a video camera worn on a first person. The data is indicative of an interaction between the first person and a second person. A physiological indicator of the second person is detected by analyzing the data. A change in the physiological indicator in the data is determined. An indication of the change in the physiological indicator in the data is transmitted to a sensory device on the first person.
