  Abstract: This is our vision: display and interact with any media type on any kind of device that you want to turn into an electronic public display. We desire to support all media types and devices that exist today as well as those that will exist tomorrow. To explore this vision, we developed two electronic public displays using Speakeasy, a foundational platform that supports ad hoc communication between devices and services with little or no a priori knowledge of one another. We discuss the design, implementation, and our experiences with these two electronic public displays.

  Abstract: Everyday humans correctly identify and classify numerous environmental sounds ranging from running water in a bathroom sink to the voices of our friends and family members. Additionally, we seem to be much more apt at correctly identifying sounds that we have already heard. For example, when we answer the telephone and recognize the voice of a family member, we rely upon some auditory memory to recognize the voice we hear on the telephone. If we are unable to correctly provide the identity of the individual on the telephone, we can often at least classify the voice as either male or female based on our memory of male and female vocal intonation and speech characteristics. Based on personal experiences with the telephone, we can infer that humans may not be able to provide the name of a walker whose footsteps they have never heard previously; however, as with the telephone, it follows that humans might be able to correctly classify the walker as either male or female.
  
  The present research examines the potential human ability to correctly identify the gender of a walker based on auditory cues alone. Specifically this work shows that the primary auditory cue that affects the listener.s ability to correctly identify a walker is the type of shoe worn during recording. Data collected through this research illustrates that humans are unable to reliably identify the gender of a walker unless he or she is wearing stereotypically gendered shoes . high heels for women and dress shoes for men. It seems as though listeners did not depend on biological information in order to distinguish footsteps as belonging to either a male or female. For example, there was seemingly no correlation between the walker.s height, weight, and gate length and an individual.s decision to identify the walker as either male or female. These results deviate significantly from those obtained in previous research.
