The HaT toilet-roll holder is an Internet of Things device that peers into an otherwise intimate space to collect patterns of paper usage and reveal valuable insights. When deployed with one participant family a particularly large spike in usage was traced back to cleaning up a dead mouse brought home by the pet cat. Use of paper during the day, while the family were all out, was finally explained by the presence of the cleaner. Part of a larger project (Hub of All Things) this device generates data for sale to companies and market researchers, via intermediaries, reversing the accepted relationship between data producer and consumer, returning ownership to the producer.
