………….The objective of this study is to create an application that helps users navigate their way in both indoor and outdoor environment. This application was created for people who often lose their way in buildings or are not able to locate their destination. We focused on testing how users can navigate their way in an indoor environment at HM building located in the Faculty of Engineering Department of King Mongkut’s Institute of Technology Ladkrabang.
The benefit of this study is to help users reach the right place in an efficient manner, saving the user both time and money that often goes in vain when navigating their ways around.
………….In 2019, the number of smartphones sold was estimated at 1.52 billion units. Additionally, the number is expected to increase to about 1.59 billion units in 2021, according to the statistic. Around 19% of worldwide population owns smartphones. Countless people have laid their hope on daily traveling to smartphone applications, such as Google maps and Apple map, since they are not only considered as a “helper” in keeping track of routes but are also a tool used to represent current traffic situation and recommend the fastest routes available. However, the problem is existing applications have yet to cover indoor spaces because GPS cannot access through walls nor hurdle through impediments in the building. In everyday life, a lot of people always go to newer places such as department stores, hospitals, schools, buildings, offices, universities, and large buildings. They tend to either lose their way or are unable to trace their destination owing to lack of information regarding the location. Thus, they end up spending more time finding and reaching the place. Although in some places there may already be maps attached near the information areas or paper maps given to customers. The place may be distant or complicated to understand. As a result, it creates difficulty for visitors who are not familiar or cannot easily find the place. These issues can be eliminated by using our application as the app is capable of detecting the user’s position, finding the user’s destination, and finally leading the user to the desired destination, for both indoor and outdoor environment.
Navigation Application for Indoor and Outdoor
………….Navigation app is a mobile application that helps users navigate their way in both indoor and outdoor environment. Our application was developed to work on smartphones, specifically the android operating systems. The application can be categorized into 2 parts with respect to its system. The first part is navigating system in an ‘outdoor’ environment using the Google API. The second part is navigating system in an ‘indoor’ environment using Bluetooth which are generally integrated within smartphones and designed to have lower power consumption capability. The indoor navigation is designed with Bluetooth Low Energy (BLE) sensors called ‘beacon’ connecting to a smart phone application. ‘Beacon’ will be installed in various points, including the front area of the room, in the building. The application is able to detect the user’s position via the closest beacon. The system will recognize the user’s position and navigate to the destination.
This GitHub repository contains implented code for front-end and back-end part of ARNutrition project.
