WI-FI BASED HUMAN PRESENCE AND MOTION DETECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329227 titled 'WI-FI BASED HUMAN PRESENCE AND MOTION DETECTION
The patent application describes a method that involves using Wi-Fi based Channel State Information (CSI) to detect motion and occupancy in a space.
- Obtaining Wi-Fi based Channel State Information (CSI)
- Filtering the CSI to remove RF interference
- Executing a motion detection module to detect motion in the space based on filtered CSI
- Providing an indication that the space is occupied upon detecting motion
- Executing an occupancy detection module to determine if the space is still occupied based on micro-movements and breath signals in the CSI
- Retaining the indication that the space is occupied if it is still occupied
- Providing an indication that the space is not occupied if it is no longer occupied
Potential Applications: - Smart home automation - Security systems - Occupancy monitoring in public spaces - Healthcare monitoring systems
Problems Solved: - Efficiently detecting motion and occupancy in a space using existing Wi-Fi infrastructure - Reducing false alarms caused by RF interference - Providing real-time occupancy information
Benefits: - Improved security and safety - Energy efficiency through automated control systems - Enhanced user experience in smart environments
Commercial Applications: Title: "Wi-Fi Based Motion and Occupancy Detection System for Smart Environments" This technology can be used in smart homes, offices, hospitals, and public spaces to automate lighting, heating, and security systems based on occupancy.
Questions about Wi-Fi Based Motion and Occupancy Detection System: 1. How does this technology improve upon traditional motion detection systems? - This technology utilizes existing Wi-Fi infrastructure for motion and occupancy detection, eliminating the need for additional sensors. 2. What are the potential privacy concerns associated with using Wi-Fi signals for occupancy detection? - Privacy concerns may arise due to the use of Wi-Fi signals to monitor occupancy, but encryption and anonymization techniques can be implemented to address these issues.
Original Abstract Submitted
a method includes obtaining wireless fidelity (wi-fi) based channel state information (csi). the method also includes filtering the csi to remove radio frequency (rf) interference. the method further includes executing a motion detection module that detects for motion in a space based on whether macro-movements are present in the filtered csi, and provides an indication that the space is occupied upon detecting motion in the space. the method also includes, in response to the indication that the space is occupied, executing an occupancy detection module that detects whether the space is still occupied based on whether micro-movements and breath signals are present in the filtered csi, retains the indication that the space is occupied upon detecting that the space is still occupied, and provides an indication that the space is not occupied upon detecting that the space is no longer occupied.
