1. Introduction

The project began as a graduation project by Gachon University's Department of AI∙Software (Software Major) and runs from 2022.03.01 to 2023.06.14. It is a project conducted by four students for about a year, and it is meaningful in improving software development skills and developing meaningful services.

MoWA, our graduation project, stands for "Monitoring the Elder with Wi-Fi Sensing and AI Speaker," and is a system that monitors the elder living alone using Wi-Fi Sensing and AI Speaker. It is Android project that is introduced here that acts as an interface with users in the MoWA project. Users can use the MoWA service by installing the MoWA application on their Android phones. Users can check their activity and risk levels through the Android application.

2. Motivation

Our project "MoWA" aims to help cope with accidents that may occur by monitoring the elder living alone and ensure the activity of the elderly living alone. The behavior of the elder living alone is monitored and checked through Wi-Fi Sensing, and real-time communication with the elder living alone is conducted through AI Speaker. In addition, the Android application allows users to utilize their own statistics and various functions (AI Speaker, phone book, and emergency contact functions, etc.)

In other words, an Android application is an application designed to make MoWA services more intuitive and easy for users to access. Therefore, we designed the UI focusing on accessibility and intuition. It was implemented with the goal and motivation to make it as easy and convenient for the elderly living alone, which is the target of our service.

3. Installation & Execution

Now, I would like to introduce how to install the MoWA application and how to run it. Unfortunately, the MoWA Android application is not currently on Google Play store. Therefore, as of this time (2023.05), the only way to install the MoWA application on the user's mobile phone is to download the repository to the computer and connect the mobile phone to install it. Although the installation method is somewhat complicated, a method of installing and executing using the method is described below.

3.1 Our Settings

For reference, the environment in which the Android project was developed is as follows. For users who want to install, you should check the difference from your environment. This is because sometimes there may be problems that cannot be executed depending on the version. In addition to what is written below, we recommend that you check the build.gradle file for more detailed settings and versions of this android project.
