Smart device

A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols such as Bluetooth, NFC, WiFi, 3G, etc., that can operate to some extent interactively and autonomously. Several notable types of smart devices are smartphones, phablets and tablets, smartwatches, smart bands and smart key chains. The term can also refer to a ubiquitous computing device: a device that exhibits some properties of ubiquitous computing including–although not necessarily–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-centered environments and distributed computing environments.

Form factors

In 1991 Mark Weiser proposed three basic forms for ubiquitous system devices: tabs, pads and boards.
