An interface is the connection point where two systems, devices, or people interact. It allows them to communicate or work together easily.
1. Identify the connection point:
Determine what needs to interact—this could be between software, hardware, or a user and a device (e.g., a touchscreen or an app menu).
2. Define how interaction happens:
Specify the rules, design, or protocols that enable the interaction (e.g., a button that submits a form or an API for data sharing).
3. Enable smooth communication:
Ensure the interface works efficiently, is easy to use, and facilitates seamless interaction between the connected elements.
