Some folks wear their hearts on their sleeves. But before long, it's more likely they'll wear their hard drives. Welcome to the age of wearable tech, where everyday attire from wristbands and eyeglasses to shirts and shoes are transformed into cutting-edge computers designed to receive, transmit, and display information in ways never before imagined. These gizmos, which often link via Bluetooth to mobile devices and actionable smartphone apps, offer a range of powerful features. Smart glasses such as Google Glass and Epson's Moverio allow users to, for example, browse and shop online, navigate to a destination, enjoy movies and music, and interact with social media. Smart watches such as Sony's SmartWatch 2 and Samsung Galaxy Gear can (depending on the device) dial or receive a mobile call, check the weather, and allow access to email, texts, calendars, and social media capabilities.
