A smart wearable device based on internet of things for the safety of children in online transportation

Abstract

The world needs to pay attention to children who often become victims of violence and cannot escape social problems. Various safety devices that are commonly known as smart wearable devices have been created, but they still have many shortcomings. Thus, in this research a safety device that can be held by children is designed and is equipped with a button that can be pressed, then it will automatically send the location and photo of the scene to the parent's cellphone via the telegram application. It uses the Raspberry Pi Zero W controller, the GNSS HMC5983 SAW LNA GPS Module to determine the location, and the 5MP Raspberry Pi Zero Camera Module to capture the incident. Based on the results, the average time needed to share locations is 0.91 seconds, and the average time needed to capture is 11.57 seconds, if the device and receiving cellphone use the same network. Additionally, the average time needed to share locations is 0.96 seconds, and the average time needed to capture is 12.09 seconds, if the device and receiving cellphone use a different network. Both conditions have 97.5% location accuracy rate and 100% photo accuracy rate.

Insights on the internet of things: past, present, and future directions

“…Wearable tech is also used in public safety. For example, it can help first responders get to an emergency faster by showing them the best way to get there, or it can keep track of construction workers' or firefighters' vital signs in places that could be dangerous [120], [156]. In healthcare, IoT has several advantages, including the capacity to more closely monitor patients via data analysis.…”

“…If IoT technology can provide devices with real-time contextual data, it's simple to see how this can improve the performance of augmented reality (AR) and virtual reality (VR) devices. Sensor data and real-time network information shown on a head-mounted display might be particularly beneficial in specific scenarios for professionals [120], [156], [322], [330], [331]: 1) head-mounted AR assists surgeons during surgery by providing data from wearables and other sensors; 2) a manufacturer is studying a virtual reality digital twin simulation of an industrial layout. In order to compare performance, IoT sensor data from the actual production floor may be shown alongside the digital twin, and 3) IoT devices help locate the item and transmit directions to the worker as a distribution center employee uses augmented reality on a mobile smartphone to locate a specific item in a warehouse.…”

“…The impact of internet of things (IoT) applications in Malaysia is expected to grow and rise by 2025 [1]. The rapid development and deployment of IoT technologies have created new opportunities for researchers and engineers in a variety of fields including healthcare [2], [3], transportation [4], industrial automation [5], agriculture [6], [7], and most interestingly smart homes [8]- [12]. In the last few decades, smart home systems have become very popular because they make life more comfortable and enjoyable.…”
