The term can also refer to a ubiquitous computing device: a device that exhibits some properties of ubiquitous computing including,but not necessary, artificial intelligence.
Smart devices can be designed to support a variety of form factors, a range of properties pertaining to ubiquitous computing and to be used in three main system environments: physical world, human-centred environments and distributed computing environments.
