Presence Simulation Control Using Audio Activity Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security systems lack the ability to effectively detect and prevent unwanted intrusions when users are away, as they rely on traditional sensors that do not adequately simulate user presence.
Innovation Solution
A monitoring and security system that uses audio pattern recognition to detect typical user activities and simulates presence by controlling devices such as TVs and lights when the user is away, creating the illusion of occupancy through a network of interconnected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensors are used to detect intrusions, then the security system can detect break-ins through windows and doors, but the system cannot effectively prevent intrusions when users are away
Solution Approach 1:
The system creates copies of normal user activity patterns (audio signatures from TVs, appliances, devices) and plays them back when users are away, making the premises appear occupied. This copying of behavioral patterns enables presence simulation without requiring actual users to be present.
Solution Approach 2:
The system pre-records audio patterns of normal household activities during periods when users are present. These pre-recorded patterns are then replayed in advance during periods when users are away, allowing the system to proactively create the illusion of occupancy before any potential intrusion occurs.
2Loss of information
If the system monitors and records audio events continuously to detect patterns, then it can identify user behavior patterns, but it increases system complexity and data processing requirements
Solution Approach 1:
The system extracts only the essential audio pattern features (presence/absence of specific device signatures, timing patterns) from continuous audio monitoring, rather than processing and storing all raw audio data. This extraction approach maintains pattern detection accuracy while significantly reducing system complexity and data processing requirements.
3Reliability
If commands are sent to multiple user devices to simulate presence, then the system can create a more realistic illusion of occupancy, but it increases the number of devices and system coordination requirements
Solution Approach 1:
The system merges the control of multiple devices under a single centralized controller that coordinates their operation based on pre-established patterns. By combining the simulation functions across multiple devices (TVs, appliances, electronic devices) and managing them through unified pattern templates, the system achieves realistic presence simulation while reducing the perceived complexity through standardized coordination protocols.

AI summary
Methods, systems and computing devices are described herein for monitoring a premises when residents or other users are present in order to detect patterns of activity at the premises. Such patterns may comprise, for example, a typical schedule indicating usage of one or more devices by one or more users of the premises. When a user is away or otherwise inactive, commands may be sent to various user devices to make it appear (e.g., to those outside the premises) as if the user is present by simulating and/or recreating the patterns that were previously detected.
