Facilitating interaction between users and their environments using a headset having input mechanisms

A headset is described herein for presenting audio information to the user as the user interacts with a space, e.g., as when a user navigates over a route within a space. The headset may include a set of input mechanisms for receiving commands from the user. The commands, in turn, invoke respective space-interaction-related functions to be performed by a space interaction (SI) module. The headset may operate with or without a separate user computing device.
