WEARABLE TECHNOLOGY DEVICES are clothing or accessories, such as
jewelery or glasses, that have connected computer devices incorporated
in their design. Such devices contain many smart sensors and are connected On/off
button
wirelessly—either via the internet or Bluetooth—to another device, such
as a smartphone, that tracks the data the wearable device collects. Wearable
technology has been around since the late 1970s, with devices such as the
calculator watch and digital hearing aid. However, progress in wearable
technology advanced rapidly in the early twenty-first century, when sensors
and chip sets became much cheaper and more readily available. Wearable
technology can have many different functions. Some devices are used to
track medical data, such as measuring heart rate, breathing patterns, Interchangeable
band
and temperature. Others are used to monitor
fitness, with many using GPS (below) to track PEBBLE

Some wearable technology is designed to
merge the digital world with the physical
world—for example, Google Glass, which
projects digital information, such as maps
and text notifications, onto the glasses’
screen without obstructing the view
of the real world. Speakers
