The vision of the Internet of Things portrays a world where physical objects are connected to the Internet, through technologies such as radio frequency identification (RFID), sensors and smartphones. Internet-enabled objects can share sensor data with web services and applications. As the physical and virtual worlds begin to interact with one another, boundaries between these worlds begin to erode. Our interaction with computers moves away from the desktop and into the environment, and becomes increasingly intertwined with our everyday lives. As this happens, we lose the ability to examine the artifacts we interact with as computing technology. They become invisible and infrastructural.
