Google Glass Real-Time Casualty Visualization

(2 Part Podcast) Google Glass-based casualty visualization system designed for tactical situational awareness. This system utilizes various radio frequency (RF) sensing technologies to detect and track different types of incidents, acting as a replacement for K9 units in certain scenarios. It processes data from RF biomarker detection, smartphone RF sensors for human anomaly and gait analysis, standoff violence detection, and even vapor detection for explosives. Ultimately, the system aims to provide real-time, geolocated alerts on Glass devices, prioritizing casualties by severity and offering a comprehensive tactical overview for emergency response.

(2 Part Podcast) The Google Glass Real-Time Casualty Visualization Demo leverages a variety of RF (Radio Frequency) sensing technologies to achieve real-time casualty detection and enhance tactical situational awareness1. These technologies serve different purposes, from detecting physiological indicators to identifying threats and anomalies, often positioning themselves as replacements for traditional K9 units.

RF Biomarker Detection (e.g., Blood Loss and Physiological Anomalies): The system can detect RF biomarkers, for instance, through smartphone Wi-Fi CSI (Channel State Information) analysis. This method simulates the detection of blood loss by identifying specific “hemoglobin signatures” and analyzes “physiological motion” indicators such as low heart rate (e.g., 45 bpm, indicating shock) and respiration rate (e.g., 8 breaths per minute). When such a detection occurs, a casualty event is registered, often with a “blood_detected” casualty type or “rf_biomarker_anomaly”.

• Smartphone RF Sensing for Human Anomaly Detection (K9 Replacement): Smartphones are utilized as RF sensors to detect human distress and anomalies, effectively replacing K9 units. This capability involves:
  • Wi-Fi CSI analysis to detect erratic movement, indicated by high variance (e.g., 0.85).
  • UWB (Ultra-Wideband) ranging to perform gait analysis, identifying abnormal gait patterns (e.g., a “limping” gait or a high gait anomaly score of 0.9) that suggest injury.
  • BLE (Bluetooth Low Energy) RSSI (Received Signal Strength Indicator) patterns to identify unusual patterns and distress indicators. These detections are processed to create a “human_anomaly_detected” casualty event.
• Standoff Violence Detection: The system employs RF reflection analysis to detect physical altercations. This technology identifies “rapid_body_movement” signatures to determine if violence is occurring within a certain range (e.g., 25 meters). Such events are classified as “violence_detected” casualties, with a severity level based on the detected threat.
• Vapor Detection (K9 Replacement): This capability simulates the use of RF dielectric analysis for detecting specific vapors, such as “explosive_signature”. It identifies changes in humidity signatures, dielectric shifts, and molecular resonance to indicate the presence of threatening vapors. This capability is also designed to serve as a replacement for K9 units in detecting various substances.

Upon detection by any of these RF sensing methods, the system processes the data, assigns a unique casualty ID, timestamp, and geolocated coordinates (latitude, longitude, altitude), and determines the casualty type, severity, and confidence level. This information is then displayed on the Google Glass device as a “casualty alert,” featuring details like the type of incident, severity (rated 1-5), confidence, source, and location. The Glass display leverages severity-based color coding (e.g., red for critical, orange for severe) and may provide recommendations such as “IMMEDIATE MEDICAL RESPONSE REQUIRED” for high-severity cases.

The Google Glass Real-Time Casualty Visualization Demo leverages several RF sensing technologies to detect casualties and enhance tactical situational awareness. These technologies serve distinct purposes in identifying various indicators of distress, injury, or threat, often presenting themselves as advanced replacements for traditional K9 units.

Here are the sensor types and their applications in detecting casualties:

• RF Biomarker Detection:
  • This system simulates the detection of physiological indicators through RF biomarkers. For instance, smartphone Wi-Fi CSI (Channel State Information) analysis can be used to identify “hemoglobin signatures,” simulating blood loss.
  • It also analyzes “physiological motion” to detect anomalies such as a low heart rate (e.g., 45 bpm, indicating shock) and an abnormal respiration rate (e.g., 8 breaths per minute).
  • When such biomarkers are detected, a “blood_detected” or “rf_biomarker_anomaly” casualty event is registered.
  • The system detects if blood_detected is true or if physiological_motion has a low heart_rate (45) or respiration_rate (8).
• Smartphone RF Sensing for Human Anomaly Detection (K9 Replacement):
  • Smartphones act as RF sensors to identify human distress and anomalies, aiming to replace K9 units.
  • This involves:
    • Wi-Fi CSI analysis to detect erratic movement, indicated by a high variance (e.g., 0.85).
    • UWB (Ultra-Wideband) ranging for gait analysis, identifying abnormal gait patterns like a “limping” gait or a high gait anomaly score (e.g., 0.9) indicative of injury.
    • BLE (Bluetooth Low Energy) RSSI (Received Signal Strength Indicator) patterns to identify unusual patterns and distress indicators.
  • These detections lead to a “human_anomaly_detected” casualty event.
• Standoff Violence Detection:
  • This capability utilizes RF reflection analysis to detect physical altercations.
  • It identifies “rapid_body_movement” signatures to determine if violence is occurring within a certain range (e.g., 25 meters).
  • Such events are classified as “violence_detected” casualties, with severity based on the detected threat level.
• Vapor Detection (K9 Replacement):
  • This system simulates the use of RF dielectric analysis to detect specific vapors, such as an “explosive_signature”.
  • It identifies changes in humidity signatures, dielectric shifts, and molecular resonance to indicate the presence of threatening vapors.
  • This function is also designed to serve as a replacement for K9 units in detecting various substances.

Upon detection by any of these RF sensing methods, the system processes the data, assigning a unique casualty ID, timestamp, geolocated coordinates, casualty type, severity, and confidence level. This information is then displayed on the Google Glass device as a “casualty alert”.

The Google Glass system displays alerts for detected casualties through a simulated visualization on the Glass device. When a casualty event is detected by one of the RF sensing technologies, the _display_glass_casualty_alert function is called to present the information.

Here’s how the system displays these alerts:

• Alert Banner: Each alert begins with a clear visual banner indicating it’s a “GOOGLE GLASS ALERT”.
• Detailed Information: The alert provides specific details about the detected casualty, including:
  • Casualty ID
  • Type of Casualty: This is dynamically displayed and formatted, for example, “Blood Detected,” “Human Anomaly Detected,” or “Violence Detected”.
  • Severity: A numerical rating out of 5 (e.g., “4/5”) is shown.
  • Confidence: The system’s confidence in the detection, presented as a percentage (e.g., “92.0%”).
  • Source: The RF sensing technology that detected the casualty (e.g., “RF Biomarker Detection,” “Smartphone RF Sensor,” “Standoff Detection”).
  • Location: Precise geolocation coordinates (latitude and longitude).
  • Time: The timestamp of the detection.
• Severity-Based Color Coding: The Glass display simulates severity-based color coding to provide a quick visual cue of the urgency. For instance:
  • 🔴 CRITICAL (Severity 5)
  • 🟠 SEVERE (Severity 4)
  • 🟡 MODERATE (Severity 3)
  • 🟢 MINOR (Severity 2)
  • ⚪ MINIMAL (Severity 1)
• Medical Response Recommendations: Based on the severity, the system provides immediate recommendations:
  • For critical or severe casualties (severity 4 or higher), it displays “🚨 IMMEDIATE MEDICAL RESPONSE REQUIRED“.
  • For moderate casualties (severity 3), it suggests “⚠️ Medical evaluation recommended”.
• Additional Glass Display Features: Beyond individual alerts, the Google Glass system offers broader tactical visualization features, including:
  • Real-time geolocation overlay.
  • Audio alerts for critical casualties.
  • Haptic feedback for proximity warnings.
  • Tactical cluster visualization for grouped incidents.

Essentially, the system processes RF sensor data and then communicates detailed, prioritized, and visually intuitive alerts directly to the user’s Google Glass for enhanced situational awareness and rapid response.

The Google Glass system handles smartphone sensor data by treating smartphones as RF sensors for human anomaly detection, effectively serving as a K9 unit replacement.

Here’s a breakdown of how the system processes this data:

• Subscription to Events: The MockGlassVisualizationSystem subscribes to “smartphone_rf_sensor” events. When data from a smartphone RF sensor is published to the communication network, the system’s _handle_smartphone_sensor_data function is triggered to process it.
• Detection Criteria: The system analyzes the incoming smartphone sensor data for specific indicators of human distress or anomaly. It checks for:
  • Wi-Fi CSI (Channel State Information) analysis: A high variance in wifi_csi (e.g., greater than 0.6) indicates erratic movement.
  • UWB (Ultra-Wideband) ranging: A high gait_anomaly_score (e.g., greater than 0.7) from UWB ranging suggests an abnormal gait pattern, such as limping, indicating a potential injury.
  • BLE (Bluetooth Low Energy) RSSI patterns: The system also considers ble_rssi patterns that show pattern_deviation or distress_indicators, though the specific logic for triggering a casualty from BLE alone isn’t detailed in the immediate processing block for casualty creation.
• Casualty Data Generation: If either the Wi-Fi CSI variance or UWB gait anomaly score exceeds their respective thresholds, the system generates casualty_data. For this type of detection, blood_detected is explicitly set to False, and a confidence level (e.g., 0.75) is assigned.
• Casualty Processing and Classification: This casualty_data is then passed to the MockCasualtyTracker for initial processing, similar to how RF biomarker detections are handled. However, a crucial step unique to smartphone sensor data is that the casualty_type is then overwritten to “human_anomaly_detected” and the source is explicitly set to “smartphone_rf_sensor”.
• Displaying the Alert: Finally, once the casualty event is classified, the _display_glass_casualty_alert function is called to visualize the alert on the Google Glass device. This alert will provide details such as the “human anomaly detected” type, severity, confidence, and location.

The system utilizes smartphone RF sensing to detect human distress signals, effectively acting as a replacement for K9 units [i].

This capability, termed “Smartphone RF Sensing for Human Anomaly Detection,” specifically identifies human distress and anomalies through the analysis of various RF signals from smartphones [i]. The sensor types and their applications in detecting these signals include:

• Wi-Fi CSI (Channel State Information) analysis [i]: This is used to detect erratic movement by analyzing high variance in Wi-Fi CSI data [i, 15]. For instance, a wifi_csi variance greater than 0.6 can trigger a detection.
• UWB (Ultra-Wideband) ranging [i]: This technology performs gait analysis to identify abnormal gait patterns, such as a “limping” gait or a high gait anomaly score (e.g., greater than 0.7), which are indicative of injury or distress [i, 6, 15].
• BLE (Bluetooth Low Energy) RSSI (Received Signal Strength Indicator) patterns [i]: The system analyzes these patterns to identify unusual patterns and distress indicators [i, 15].

When such indicators are detected, the system registers a “human_anomaly_detected” casualty event [i, 6]. The source of this detection is explicitly identified as “smartphone_rf_sensor”.

A violence detection alert is triggered by the Standoff Violence Detection capability of the system [i]. This capability specifically utilizes RF reflection analysis [i].

The system detects violence by identifying “rapid_body_movement” signatures [i]. When violence_detected is true in the standoff detection data, indicating that a physical altercation is occurring within a certain range (e.g., 25 meters), a casualty event is registered [i, 16].

Upon detection, the system assigns a casualty_type of “violence_detected” and sets the source as “standoff_detection”. The severity of this alert is determined by the threat_level indicated in the detection data. Once processed, this information is then displayed on the Google Glass device as a casualty alert.

Two RF sensing sources mentioned in the provided information are:

1. RF Biomarker Detection: This capability detects casualties, such as blood loss, by analyzing RF biomarkers [i, 3]. When a “bloodsignal_detection” event is published, it triggers the processing of RF biomarker data, which can then lead to a “blood_detected” casualty alert being displayed on Google Glass [i, 4, 5, 13].
2. Smartphone RF Sensor: Smartphones are utilized as RF sensors to detect human anomalies and distress signals, effectively acting as a K9 unit replacement [i, 1, 4]. This involves analyzing Wi-Fi CSI for erratic movement, UWB ranging for abnormal gait patterns (like limping), and BLE RSSI patterns for distress indicators [i, 5, 6, 15]. When such anomalies are detected, a “human_anomaly_detected” casualty alert is generated and displayed [i, 6].
