GuideShoes is a wearable system that explores how aesthetic forms of expression can deliver both an aesthetic experience and background information simultaneously while walking around a city. Incorporating GPS, wireless spread-spectrum technology, and a MIDI synthesizer, the system tracks the user, and selects and assembles small musical patterns dynamically dependent on the user's progress. Statistically significant results of user testing have shown that users that listened to the musical cues provided by the GuideShoes system were able to extract navigational signals, such as "continue" or "you made a wrong turn" from the musical experience.
