The HoloToolkit InputManager is a singleton responsible for managing input sources and dispatching corresponding events to the various input handlers. Input sources for HoloLens include gestures and voice commands.
MixedRealityToolkit provides a number of different input event handler components, some of which we'll be using in this project. For example, IInputClickHandler provides an interface for click events, like those generated when the user does a select hand gesture (pinching the forefinger and thumb together). The input handlers can be found in the HoloToolkit/Input/Scripts/InputEvents/ folder, a summary of which is shown ahead.
