A Study and Estimation a Lost Person Behavior in Crowded Areas Using Accelerometer Data from Smartphones
As smartphones become more popular, applications are being developed with new and innovative ways to solve problems in the day-to-day lives of users. One area of smartphone technology that has been developed in recent years is human activity recognition (HAR). This technology uses various sensors that are built into the smartphone to sense a person\u27s activity in real time. Applications that incorporate HAR can be used to track a person\u27s movements and are very useful in areas such as health care. We use this type of motion sensing technology, specifically, using data collected from the accelerometer sensor. The purpose of this study is to study and estimate the person who may become lost in a crowded area. The application is capable of estimating the movements of people in a crowded area, and whether or not the person is lost in a crowded area based on his/her movements as detected by the smartphone. This will be a great benefit to anyone interested in crowd management strategies. In this paper, we review related literature and research that has given us the basis for our own research. We also detail research on lost person behavior. We looked at the typical movements a person will likely make when he/she is lost and used these movements to indicate lost person behavior. We then evaluate and describe the creation of the application, all of its components, and the testing process
Ubitrack: A Study on Lost Person Activity Estimation Using Accelerometer Data from Smartphones
As smartphones become very more popular, applications are being developed with new and innovative ways to solve problems faced in the day-to-day lives of users. One area of smartphone technology that has been developed in recent years is human activity recognition HAR. This technology uses various sensors that are built into the smartphone to sense a person\u27s activity in real time. Applications that incorporate HAR can be used to track a person\u27s movements and are very useful in areas such as health care. In our research, we use this type of motion sensing technology, specifically, using data collected from the accelerometer sensor. The purpose of this study is to estimate the pilgrim who may become lost on the annual pilgrimage to Hajj. The application is capable of estimating the movements of people in a crowded area, and of indicating whether or not the person is lost in a crowded area based on his/her movements as detected by the smartphone. This will be a great benefit to anyone interested in crowd management strategies, specifically regarding Hajj. In this thesis, we review related literature and research that has given us the basis for our own research. For example, we could not create this application without the use of HAR technology and without specific classification algorithms. We also detail research on lost person behavior. We looked at the typical movements a person will likely make when he/she is lost and used these movements to indicate lost person behavior. We then describe the creation of the application, all of its components, and the testing process. Finally, we discuss the results of our trials and plans for future work
Advancements In Crowd-Monitoring System: A Comprehensive Analysis of Systematic Approaches and Automation Algorithms: State-of-The-Art
Growing apprehensions surrounding public safety have captured the attention
of numerous governments and security agencies across the globe. These entities
are increasingly acknowledging the imperative need for reliable and secure
crowd-monitoring systems to address these concerns. Effectively managing human
gatherings necessitates proactive measures to prevent unforeseen events or
complications, ensuring a safe and well-coordinated environment. The scarcity
of research focusing on crowd monitoring systems and their security
implications has given rise to a burgeoning area of investigation, exploring
potential approaches to safeguard human congregations effectively. Crowd
monitoring systems depend on a bifurcated approach, encompassing vision-based
and non-vision-based technologies. An in-depth analysis of these two
methodologies will be conducted in this research. The efficacy of these
approaches is contingent upon the specific environment and temporal context in
which they are deployed, as they each offer distinct advantages. This paper
endeavors to present an in-depth analysis of the recent incorporation of
artificial intelligence (AI) algorithms and models into automated systems,
emphasizing their contemporary applications and effectiveness in various
contexts
