One of the prototype products developed by Apple, according to The New York Times, is a "curved-glass iPod that would wrap around the wrist." Users could interact with this device by using their voice, like with Siri on the iPhone 4S.
Another experimental idea from Apple has been small, wearable devices that could be used to input information on another, more powerful device like an iPhone. These accessories could also wirelessly display information on other devices, like iPods.
Apple's interest in wearable electronics has reportedly been spearheaded by a very small group of employees at the company. But prototypes of some wearable devices have allegedly been built by the company.
Author Nick Bilton said Apple is not alone in its pursuit of these devices: Google, too, is said to have been working on wearable computers that could connect to Android smartphones. Calling the smartphone the "first wearable computer," Bilton said smartphones will eventually become the "hub" for all information, "transmitting power and Internet access to sensors and screens that are tacked on to our clothing."
Of course, Apple has produced wearable version of the iPod for years, and currently sells the iPod shuffle and iPod nano, both of which include a clip so it can be attached to clothing. The iPod nano, which includes a multi-touch display, can also be worn as a watch with available accessories.
Though the tiny iPod nano includes a standard 30-pin iPod dock connector, it does not include any wireless functionality that would allow it to wirelessly communicate with an iPhone. As it stands, the iPod nano is a standalone media playback device.
But Bilton's report envisions a future where all devices are connected, and wearable electronics could include glasses or even contact lenses with built-in screens, capable of displaying information to users.
