Anbspsmartwatchnbsp(ornbspsmart watch) is anbspcomputerizednbspwristwatch with [[function]]ality that is enhanced beyondnbsptimekeeping. While early models can per[[form]] basic tasks, such asnbspcalculations,nbsptranslations, andnbspgame-playing, modern smartwatches are effectivelynbspwearable computers. Many smartwatches runnbspmobile apps, while a smaller number of models run anbspmobile operating systemnbspand [[function]] asnbsppor[[table]] media p[[layer]]s, offering playback ofnbspFM radio, audio, and video files to the user via anbspBluetoothnbsp[[head]]set. Some smartwatches models, also callednbspwatch phones, feature fullnbspmobile phonenbspcapability, and can make or answer phone calls.[1][2][3] Such devices may include features such as anbspcamera,nbspaccelerometer,nbspthermometer,nbspaltimeter,n

  2. Some also have " sport watch" [[function]]ality withnbsp activity trackernbspfeatures (also known as " fitness tracker") as seen innbsp GPS watchesnbspmade for Training, Diving, and Outdoor sports. [[function]]s may include training programs (such as intervals), Lap times, speed display,nbsp GPS tracking unit, Route tracking,nbsp dive computer,nbsp heart rate monitornbspcompatibility,nbsp Cadencenbspsensor compatibility, and compatibility with sport transitions (as innbsp triathlons).

  • Like othernbsp computers, a smartwatch may collect in[[form]]ation from internal or external sensors. It may control, or retrieve data from, other instruments or computers. It may support wi[[rel]]ess technologies like Bluetooth,nbsp Wi-Fi, and GPS. However, it is possible a "wristwatch computer" may just serve as a front end for a remote system, as in the case of watches utilizing cellular technology or Wi-Fi.

Despite the growing market for smart watches and activity trackers, the ear is a much better source of data because it offers an area where blood flows neatly in and out, providing a much stronger signal and less noise. Wearables with Valencell Per[[form]]Tek biometrics measure signals with the [[body]] through the ear with an optical emitter, photodetector, and accelerometer into an earbud. Valencells technology has also been implemented in heart rate monitoring armbands (such as the Scosche Rhythm).nbsp[4]
