(February 2015) (Learn how and when to remove this template message) The Apple Watch, released in 2015 Wearable computers, also known as body-borne computers or wearables are miniature electronic devices that are worn under, with or on top of clothing.[1] This class of wearable technology has been developed for general or special purpose information technologies. It is also used in media development. Wearable computers are especially useful for applications that require more complex computational support, such as accelerometers or gyroscopes, than just hardware coded logic. Wearable computing devices are variously defined. For example, consumers often refer to wearable computers as computers that can be easily carried on the body, or systems with a heads-up display or speech activated. This contrasts with academics that define wearables as a system that can perform a set of functions without being constrained by the physical hardware of the system.
