Google Glass is a wearable computer in the form of a headset that looks like a pair of glasses and lets users
accomplish various tasks and receive quick information in a smartphone form. The difference is that Google Glass is
used hand-free and does not require the user to look away to receive information, which is officially called a heads -
up display. Google Glass was created to ease the user’s daily and social life by taking the bulky and physical part of
technology out of the way to help the user connect to th world in a faster way. It is connected to the Internet, and the
user can take photographs, record videos, send and receive messages, and stream live recordings, amongst others. It
supports Apps that people can develop for Google Glass using its API, which is called Mirror API.
The idea of having a wearable computer with a heads -up display is not new. MIT researchers Thad Starner
and Steve Mann have been working on these devices for almost half a century. Mann stated the idea behind a
wearable co mputer as “Wearable co mputing, however, is based on the idea that computing is NOT the primary
task”. He believes that the wearable computer should augment the user’s senses . Other companies started working
on heads-up displays, perhaps sharing Mann’s view, whether knowingly o r unknowingly, but with the similar idea to
help the user’s life. Ca r co mpanies were one of the first to include comme rcia lly -available heads-up displays on
their windshields to give the driver information about directionsor speed limits.
