This study introduces a non-intrusive method using Machine Learning to detect and count people in smart environments. The system accurately determines indoor occupancy for enhanced user experience.
Area of Science:
- Computer Science
- Artificial Intelligence
- Ubiquitous Computing
Background:
- Smart Environments aim to enhance user comfort by adapting conditions based on occupant presence.
- Current methods often involve intrusive data collection, necessitating non-intrusive alternatives.
- Accurate occupancy detection is crucial for effective environment adaptation.
Purpose of the Study:
- To propose and validate a non-intrusive solution for detecting and estimating the number of occupants in indoor smart environments.
- To leverage Machine Learning techniques for improved user experience in smart spaces.
- To develop a prototype system for real-world data acquisition and analysis.
Main Methods:
- Implementation of Machine Learning algorithms for occupant detection and counting.
- Development of a prototype system with integrated nodes and sensors for environmental data gathering.
- Non-intrusive data collection from indoor areas.
- Application of pattern recognition mechanisms for data analysis.
Main Results:
- The developed prototype system successfully gathered, processed, and stored environmental data.
- Machine Learning analysis of the collected data enabled accurate determination of indoor environment occupancy.
- The non-intrusive approach proved effective in identifying and estimating occupant numbers.
Conclusions:
- The proposed system effectively determines indoor occupancy using non-intrusive methods and Machine Learning.
- This approach enhances user experience in smart environments by enabling adaptive conditions.
- The research demonstrates the feasibility of real-time occupancy estimation for smart environment applications.
