| + | The software component of the Bloem project is responsible for enabling the interaction between the user and the capsule environment. It consists of a mobile application installed on a tablet and an embedded control system running on a microcontroller. Together, these elements allow the user to book sessions, control environmental settings, and experience a guided relaxation process. | ||
| + | |||
| + | The tablet application acts as the main interface between the user and the system. It is designed with a calm and minimal user interface, using simple navigation, large touch elements, and soft visual feedback to align with the relaxing purpose of the capsule. The application allows users to quickly book a session, select a time slot, and adjust lighting and sound settings without unnecessary complexity. | ||
| + | |||
| + | The embedded system, implemented using a microcontroller (ESP32), is responsible for executing commands received from the tablet application. It controls the lighting system, manages audio triggers, and processes sensor data when necessary. This separation between interface and control ensures modularity and simplifies both development and maintenance. | ||
| + | |||
| + | **Use Cases and User Stories** | ||
| + | |||

| + | |||
| + | **Selection of Development Platforms and Software Components** | ||
| + | |||
| + | The Bloem system requires both a front-end application and an embedded control system. Different options were considered for the tablet application. | ||

| + | |||
| + | For Bloem, a **native Android application** is considered the most suitable option. It allows direct integration with the tablet hardware, ensures smooth performance, | ||

| + | </ | ||
| + | </ | ||
| + | |||
| + | **Software Architecture** | ||
| + | |||
| + | The software architecture is divided into two main layers: the user interface layer and the hardware control layer. | ||
| + | |||
| + | The tablet application manages all user interactions, | ||
| + | |||
| + | The ESP32 receives these commands and applies them to the physical lightning component. | ||
| + | |||
| + | This architecture ensures a clear separation between user interaction and hardware control, making the system easier to develop, test, and extend. | ||
