Body-worn wearable computers, or wearables for short, are small, portable electronic devices that are to be worn on the body of the user or integrated into their clothing. The idea behind them is to give the users easy access to information and computing power. These devices are also often aware of their user and the environment they are in. This allows them to offer contextual information and react to the user's surroundings, location, their body position, bodily functions, or even mental state.
We define body-worn wearables as devices that are mounted on human body and exhibit cognition enhancing abilities. (Please note that for the purposes of this knowledge base, Head-mounted Devices are considered to be a stand-alone category.) Our dichotomy is based on how the IEC 62209-2:2010 standard distinguishes the devices based on their position on the human body.
