Intended Usage

This project is designed to be versatile in its input methods, catering to various user needs:

Adaptive Controllers

The primary intended usage is with adaptive controllers, such as the Xbox Adaptive Controller or similar devices. These controllers are specifically designed to meet the needs of gamers with limited mobility, making gaming more accessible to a wider audience.

• Xbox Adaptive Controller: A unified hub for devices that helps make gaming more accessible. It works with a range of external devices such as switches, buttons, mounts, and joysticks to create a custom controller experience.

While optimized for use with the Xbox Adaptive Controller, it can also be used with other similar adaptive gaming devices.

Standard Input Devices

The application also fully supports standard input methods:

• Keyboard: Users can navigate and interact with the application using keyboard inputs.
• Mouse: Full mouse support is available for point-and-click interactions.

This multi-input approach ensures that the application is accessible and usable for a wide range of users, regardless of their preferred or required input method.
