Zach and myself collaborated on the native Android application which would analyze raw sensor data streaming from the shoes to algorithmically identify various movements such as walking, jumping, kicking, sitting, and twirling.  When an activity is detected, the shoe provides audio feedback in the form of a voice announcing pithy remarks such as "Try harder" or "My mother can jump higher than you".   Upon ending a session, the user is then presented a 'badge' in the form of a GIF which they could post directly to Google+.  

The goal of the Art, Copy, Code team at Google was to make a case for how wearable, connected objects can tell stories about our quantified physical lives. The project got almost too much attention, and Google had to issue a press release saying that no, they were not in fact working with Adidas to create a shoe product: this was simply an experiment.
