Sensor Walk

The slideshow above documents my Physical Computing sensor walk. I walked down Broadway from Union Square to Tisch, noting all of the sensors I could spot along the way. There was an abundance of door bells and apartment buzzers (which had buttons, microphones, and sometimes cameras). I also noted a few other types of sensors such as security cameras, ATM card readers for unlocking vestibule doors, proximity card sensors, and motion sensors to open doors. I also spotted glass breakage sensors on shop doors, shop lifting sensors and people counters. Newsstands had barcode readers from the New York State Lottery and the FDNY and NYPD had call a call box strapped to a light pole. If you want to pay for parking, a machine reads your credit card or accepts coins (multiple sensors, I’m sure) and selections are made by pushing buttons. I’m sure that entering any of these buildings, storefronts, buses and subway stops along with way would have revealed even more sensors.
