SMARTWATCH

A smartwatch is an electronic bracelet with clock. While early models can perform basic tasks, such as calculations, digital time, translations, and game-playing. 2010 smartwatches are effectively wearable computers. Many run mobile apps, using a mobile operating system and Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, also called 'watch phones' (or vice versa), feature full smartphone capability, and have complete functionality of a typical smartphone.

While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED or Hologram. Some use transflective or electronic paper, to consume less power. Most have a rechargeable battery and many have a touchscreen. Peripheral devices may include digital cameras, thermometers, accelerometers, pedometers, heart rate monitors, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD card (that are recognized as a storage device by a computer).
