1. A computing device, implementing a space interaction module, for assisting a user in interacting with a space, comprising: a sound generation module configured to generate a three-dimensional sound, the three-dimensional sound creating a perception, by a user, that the three-dimensional sound emanates from at least one particular location within the space; and a path guidance module configured to use the sound generation module to generate a three-dimensional periodic sound that, when presented to the user, directs the user in a particular direction within the space.
