Editing Smart device (section)

== Environments ==
The term ''smart device environments'' has two meanings. First, it can refer to a greater variety of device environments. Three different kinds of environments for devices can be differentiated:<ref name="Poslad"/>
* ''Virtual computing environments'' that enable smart devices to access pertinent services anywhere and anytime.
* ''Physical environments'' that may be embedded with a variety of smart devices of different types including tags, sensors and controllers. These can have different form factors ranging from nano to micro to macro sized.
* ''Humans environments'': humans, either individually or collectively, inherently form a smart environment for devices. However, humans may themselves be accompanied by smart devices such as mobile phones, use surface-mounted devices ([[wearable computing]]) and contain [[embedded device]]s (e.g., [[pacemaker]]s to maintain a healthy heart operation).
Second, the term ''smart device environments'' can also refer to the concept of a [[smart environment]] which focuses more specifically on the physical environment of the device. The physical environment is smart because it is embedded or scattered with smart devices that can sense and control part of it.
