In the physical world, when you press a button, it responds to your interaction. Subconsciously, we expect the same experience when communicating with digital controls. In other words, if users struggle to understand if it's a button or label or if it's clickable or disabled, it means your app doesn't provide enough feedback.

What kind of feedback can you create for buttons?

• Visual: Elevated buttons with a natural shadow and color that changes on tap are irresistible. A nice subtle animation can also encourage users to move forward.
• Tactile: A slight device vibration on tap helps users understand that the system has registered their action.

A final reminder — keep the button design tasteful and functional. Using all visual and tactile tools at the same time can easily overwhelm users.
