Input

Input allows the user to control your application using a device, touch, or gestures. You can program in-app elements, such as the graphic user interface (GUI) or a user avatarAn interface for retargeting animation from one rig to another. More info
See in Glossary, to respond to user input in different ways.

Unity supports input from many types of input devices, including:

• Keyboards and mice
• Joysticks
• Controllers
• Touch screens
• Movement-sensing capabilities of mobile devices, such as accelerometers or gyroscopes
• VR and ARAugmented Reality (AR) uses computer graphics or video composited on top of a live video feed to augment the view and create interaction with real and virtual objects.

Unity supports input through two separate systems:

• The Input ManagerSettings where you can define all the different input axes, buttons and controls for your Project. More info
  See in Glossary is part of the core Unity platform and available by default.
• The Input System is a package that needs to be installed via the Package Manager before you can use it. It requires the .NET 4 runtime, and doesn’t work in projects that use the old .NET 3.5 runtime.

Note: As of Unity 2020.1, the Input System package is still in preview, so it’s not ready for use in production Projects. Some functionality is under development, and existing features might change with future updates.
