Gaze, gesture, and voice together are the next generation of natural user input. This input system allows for interaction with your digital content and communication with your HoloLens device with no additional accessories needed.
In addition, we have provided a clicker with each Microsoft HoloLens Development Edition. The clicker offers another way to do things like select and scroll. Because HoloLens is a Bluetooth-enabled device, you may also choose to connect a keyboard for some scenarios.
