Space interaction (SI) functionality is described herein for assisting a user in interacting with a space. The SI functionality includes a sound generation module that generates three-dimensional sounds in various circumstances. A three-dimensional sound is perceived by a user as emanating from particular location within the space. Different modules may leverage the three-dimensional sounds for different purposes. In one implementation, a path guidance module uses a three-dimensional beat sound to direct the user in a particular direction. An exploration module uses three-dimensional sounds to identify the locations of items of interest that lie within (or are otherwise associated with) a subspace to which an attention of the user is currently directed. An orientation module uses three-dimensional sounds to identify the locations of items of interest that are associated with an entire space around the user.
