Solution Overview

Problem

Current augmented reality systems lack the capability to automatically and intelligently capture images or videos based on sudden changes in motion sensor data from wearable devices, such as detecting emergency or threatening events, which limits their effectiveness in real-time applications.

Innovation Solution

A device trigger system integrated into wearable devices, such as head-wearable apparatus, that detects sudden changes in motion sensor data and automatically captures images or videos, then transmits them to connected devices or servers for processing and alerting purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automatic media capture is implemented using motion sensor data, then the ability to detect and respond to emergency events is improved, but the device complexity increases

Engineering Contradiction:

Improveemergency event detection capabilityVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple existing components (motion sensors, media capture device, transmission system) into an integrated wearable device that automatically detects emergencies and responds. This merging approach improves reliability by creating a cohesive emergency response system while managing complexity through unified design rather than separate interconnected systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary configuration by establishing motion thresholds and capture parameters before emergencies occur. The motion sensors continuously monitor for abnormal movements, and capture settings are pre-configured to trigger automatically when specific motion patterns are detected, eliminating the need for complex real-time decision-making algorithms.

Inventive Principle:

Principle #10Preliminary action

2Loss of time

If real-time media capture and transmission is enabled, then the response time to emergencies is improved, but the energy consumption increases

Engineering Contradiction:

Improveemergency response timeVSAvoiddevice power consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system uses periodic motion sampling rather than continuous media capture and transmission. Motion sensors take periodic readings and only trigger media capture when motion exceeds predetermined thresholds, converting continuous high-energy operations into periodic low-energy operations that maintain emergency detection capability while reducing overall power consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The wearable device autonomously monitors its own operational state and automatically triggers capture and transmission only when motion anomalies are detected. This self-service approach eliminates the need for manual activation or continuous monitoring systems, enabling rapid response to emergencies while consuming energy only when necessary.

Inventive Principle:

Principle #25Self-service
