The system of any one of claims 28 to 34, wherein the analytics component is further configured to extract features from the sound corresponding to a pattern of sounds associated with the user, wherein the features characterize interactions considered unusual between the user and the device based on the pattern.
  36. 36. The system of claim 35, wherein the features characterise distress.
  37. 37. The system of claim 35, wherein the sounds associated with the user includes sounds associated with appliances.
  38. 38. The system of claim 35, wherein the sounds associated with the user includes sounds associated with an event, including the acoustic signals associated with household fixtures.
  39. 39. The system of any one of claims 35, wherein the analytics component comprises a cloud-based host system configured to identify sounds indicative of interactions considered unusual between the user and the device based on the pattern.
  40. 40. The device of any one of claims 35, wherein the analytics component comprises a locally-based host system configured to identify data indicative of interactions considered unusual between the user and the device based on the pattern.
  41. 41. A method of tracking at least one user, the method comprising: receiving sound information from a plurality of devices; extracting features from the sound information; creating a pattern of sounds associated with the user; and characterising interactions considered unusual between the user and the plurality of devices based on the pattern.
