Input patterns are the ways users enter, edit, and submit data or commands in your product. Forms are collections of input fields that users fill out to provide information or perform actions, and are useful when you need to collect structured and validated data. Buttons are elements that users click or tap to trigger an action or a change in the product, and can provide clear and immediate feedback to users. Sliders are elements that users drag or swipe to adjust a value or a range within a predefined scale, allowing more control and flexibility over their input. Search is a feature that allows users to enter a keyword or phrase and find relevant content or functionality in your product, which is especially useful when you have a large amount of content or features. To apply input patterns to different scenarios, you must consider the type, complexity, and frequency of the input required from your users, as well as the feedback and guidance you provide. For instance, if designing a music app, you might use forms for creating playlists, buttons for playing music, sliders for adjusting the volume and playback speed, and search for finding songs, artists, or genres.
