Voice

The last but hardly the least important form of input for the HoloLens is Voice. The Voice component is designed to let the user look at a hologram, see any commands associated with that hologram, and simply say the command out loud to invoke it.

A convention has been laid out for developers. See it, say it means that if you have a voice command for the user input, a label with the appropriate button should be visible; for instance, a button that causes robots to destroy a village in a game might say destroy. When the user Gazes at the village and utters the word, he can smile as the army of robots descend on those poor villagers. Oh, the humanity!
