Abstract: 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.

Abstract: Systems and method for supporting a cover material to a support material include a coupling device that includes an inner coupler and an outer coupler. The inner coupler and the outer coupler are separably joined. The inner coupler may be attached to the support material, and the outer coupler may be attached to the cover material.

Abstract: Aspects of the present disclosure relate to structure switching in a 3D environment. In examples, an authoring application is used to select characteristics for the 3D environment and to insert content. For example, a structure is selected in which to present the content in the 3D environment. An asset container comprises assets associated with the selected structure, which are included in the 3D environment. In some examples, a common asset container comprises other assets that are included in the 3D environment. End users are able to view the 3D environment using a viewer application. If the author decides to change the selected structure, an asset container associated with the new structure is identified. Assets for the old structure are removed from the 3D environment and assets for the new structure are included instead. Thus, a set of asset containers is used generate the 3D environment and change characteristics therein.

Abstract: Examples of the present disclosure describe systems and methods for rendering 3D text in a 3D environment. In aspects, a three dimensional (3D) object may be generated in a virtual reality, augmented reality, or mixed reality (MR) environment.

A graphical control element, such as a text frame, and associated content may be rendered on the GUI texture. In some aspects, the graphical control element may be associated with editing controls that enable the dimensions and/or orientation of the graphical control element to be modified within the boundaries of the GUI texture and/or the 3D object.

Abstract: Systems and methods of maintaining a focal point of a camera in a 3D environment of a 2D graphical user interface of an authoring application includes displaying a surface upon which one or more content items can be placed and a camera centrally positioned relative to the surface. Further, responsive to an indication to add a content, determining a first elevation of the camera, determining an angle of view of the camera at the first elevation and elevating the camera to a second elevation that is greater than the first elevation of the camera while maintaining a perceived angle of view of the camera. Systems and methods for translating a 3D object include preventing translation of the 3D object in one of three dimensions of the three-dimensional environment while enabling simultaneous translation of the 3D object in the two remaining dimensions of the three dimensions of the 3D environment.

Abstract: Methods and systems for displaying a content indicator in a 3D environment of a 2D graphical user interface of an authoring application includes receiving an indication to load the object into the 3D environment, displaying the content indicator, which indicates a loading status of the object, based on receipt of the indication and scaling the content indicator. The scaling includes determining a forward direction of the camera, determining a difference in position between the forward direction of the camera and the content indicator, determining a scalar value based on the difference in position and applying the scalar value to the content indicator.

Abstract: A flexible layout system is disclosed herein that improves infinite scrolling capabilities and other animations in software calendars. In an implementation, a time period of a viewport in a user interface may change relative to a panel in a calendar. As the viewport changes, a mapping component informs other components of a new time period coming into view in the view port as a result of a scrolling event. The mapping component may also respond to requests from another component with layout information for the visual representation of the new time period (e.g. position and dimension). In this manner, the responsibility for determining layout information is encapsulated.
