CONTEXTUAL INPUT IN A THREE-DIMENSIONAL ENVIRONMENT

Aspects of the present disclosure relate to contextual input in a three-dimensional (3D) environment. In an example, a 3D environment is authored using an authoring application, wherein the author selects and positions one or more content items within the 3D environment. The 3D environment has a set of possible environment events that are associated with user input events. As a result, an environment event is generated when a user input event is received from an input device. An author uses the authoring application to associate an environment event with an action of the content item. A user is able to use a variety of input devices to interact with the 3D environment. When an input event is received from an input device, an environment event is generated accordingly, and a content item action associated with the environment event is performed in response to the environment event.
