Smartphone capabilities have extended, even to the wristwatch. Companies like Apple, Nike, Sony, as well as other startups, have created new wrist devices that connect to an individual’s smartphone. Most display the time, but the bands also provide information that keeps users from having to take out their mobile devices. Sony, for example, released its Smartwatch, which includes a 2" screen that displays emails, Twitter posts, and other kinds of texts. Other devices track a user's daily activity.
