| CameraParameters | When calling PhotoCapture.StartPhotoModeAsync, you must pass in a CameraParameters object that contains the various settings that the web camera will use. | 
| GestureErrorEventArgs | Contains fields that are relevant during an error event. | 
| HoldCanceledEventArgs | Contains fields that are relevant when a user cancels a hold gesture. | 
| HoldCompletedEventArgs | Contains fields that are relevant when a hold gesture completes. | 
| HoldStartedEventArgs | Contains fields that are relevant when a hold gesture starts. | 
| InteractionSource | Represents one detected instance of an interaction source (hand, controller, or user's voice) that can cause interactions and gestures. | 
| InteractionSourceDetectedEventArgs | Contains fields that are relevent when an interaction source is detected. | 
| InteractionSourceLostEventArgs | Contains fields that are relevent when an interaction source is lost. | 
| InteractionSourcePose | Pose data of the interaction source at the time of either the gesture or interaction. | 
| InteractionSourcePressedEventArgs | Contains fields that are relevent when an interaction source enters the pressed state for one of its buttons. | 
| InteractionSourceProperties | Represents the set of properties available to explore the current state of a hand or controller. | 
| InteractionSourceReleasedEventArgs | Contains fields that are relevent when an interaction source exits the pressed state for one of its buttons. | 
| InteractionSourceState | Represents a snapshot of the state of a spatial interaction source (hand, voice or controller) at a given time. | 
| InteractionSourceUpdatedEventArgs | Contains fields that are relevent when an interaction source updates. | 
| ManipulationCanceledEventArgs | Contains fields that are relevant when a manipulation gesture is canceled. | 
| ManipulationCompletedEventArgs | Contains fields that are relevant when a manipulation gesture completes. | 
| ManipulationStartedEventArgs | Contains fields relevant when a manipulation gesture starts. | 
| ManipulationUpdatedEventArgs | Contains fields that are relevant when a manipulation gesture gets updated. | 
| NavigationCanceledEventArgs | Contains fields that are relevant when a navigation gesture is canceled. | 
| NavigationCompletedEventArgs | Contains fields that are relevant when a navigation gesture completes. | 
| NavigationStartedEventArgs | Contains fields that are relevant when a navigation gesture starts. | 
| NavigationUpdatedEventArgs | Contains fields that are relevant when a navigation gesture updates. | 
| RecognitionEndedEventArgs | Contains fields that are relevant when recognition of a gesture event ends. | 
| RecognitionStartedEventArgs | Contains fields that are relevant when recognition of a gesture event begins. | 
| SurfaceData | SurfaceData is a container struct used for requesting baked spatial mapping data and receiving that data once baked. | 
| SurfaceId | SurfaceId is a structure wrapping the unique ID used to denote Surfaces.  SurfaceIds are provided through the onSurfaceChanged callback in Update and returned after a RequestMeshAsync call has completed.  SurfaceIds are guaranteed to be unique though Surfaces are sometimes replaced with a new Surface in the same location with a different ID. | 
| TappedEventArgs | Contains fields that are relevant when a tap gesture occurs. |
