[[File:3D_User_Interaction.jpg|thumb|528x528px|Scheme of 3D User Interaction phases]]{{About|includes physical 3D input/output devices|3D user interfaces as software|3D GUI|section=yes}}[[User interface|User interfaces]] are the means for communication between users and systems. 3D interfaces include media for 3D representation of system state, and media for 3D user input or manipulation. Using 3D representations is not enough to create 3D interaction. The users must have a way of performing actions in 3D as well. To that effect, special input and output devices have been developed to support this type of interaction. Some, such as the 3D mouse, were developed based on existing devices for 2D interaction.

3D user interfaces, are user interfaces where 3D interaction takes place, this means that the user's tasks occur directly within a three-dimensional space. The user must communicate with commands, requests, questions, intent, and goals to the system, and in turn this one has to provide feedback, requests for input, information about their status, and so on.
