**2. Construction of mobile terminal system**

### **2.1 System overview**

Currently, Android, iOS, etc., are the mainstream operating systems for smartphones, and the system construction method is different for each. In this research, we focus on Android as an example (**Figure 2**), but if a similar API is used, it will be possible to develop the same for iOS.

In addition to using Android Studio in Android development, functions such as map function and geocoding use google API, and it is necessary to use google developers console to use these(**Table 1**).
