Samsung Galaxy Gear

The Samsung Galaxy Gear is a smartwatch produced by Samsung Electronics in the Samsung Gear family of devices. Unveiled during a Samsung Unpacked event in Berlin, Germany on September 4, 2013, the device serves as a companion for all Samsung Galaxy smartphones and tablets which run Android 4.3 or newer; it was released on September 25, 2013. Originally released as an Android-based device, Samsung replaced the operating system with Tizen through the May 2014 software update.

The Gear's successor, the Gear 2, was released on April 11, 2014.

History

Development

The development of the Galaxy Gear came in the midst of a push towards the growing smartwatch market; Samsung's main competitor Apple had been the subject of rumors suggesting an upcoming watch product, while the Kickstarter-backed Pebble (which reached mass market availability in July 2013) has been credited with creating mainstream interest in the concept. Lee Young-hee, vice president of Samsung's mobile business, revealed in July 2013 that the company had been working on a watch for a long time, and referred to it as a "product for the future". In August 2013, Bloomberg reported that "two people familiar with the matter" claimed Samsung would introduce a smartwatch, tentatively known as the "Galaxy Gear", on September 4, 2013 during a Samsung Unpacked event prior to the IFA consumer electronics trade show in Berlin. Samsung was also expected to unveil the Galaxy Note 3 phablet during the event as well.

Samsung Gear

Samsung Gear is a line of wearable computing devices produced by Samsung Electronics. The line was first introduced with an Android smartwatch in September 2013 as a spin-off of its Galaxy smartphone and tablet range, and expanded at Mobile World Congress 2014 with a successor, the Tizen-based Gear 2, and the Gear Fit activity tracker.

Samsung Galaxy

Samsung Galaxy (stylized as Samsung GALAXY or SAMSUNG Galaxy) is a series of mobile computing devices designed, manufactured and marketed by Samsung Electronics. The product line includes the Galaxy S series of high-end smartphones, the Galaxy Tab series of tablets, the Galaxy Note series of tablets and phablets with the added functionality of a stylus and the first version of the Galaxy Gear smartwatch, with later versions dropping the Galaxy branding.

Samsung Galaxy devices have traditionally used the Android operating system produced by the Open Handset Alliance led by Google, usually with a custom user interface called TouchWiz. This tradition was broken at CES 2016 with the announcement of the first Galaxy-branded Windows 10 device, the Samsung Galaxy TabPro S.

Categorization

Since August 2015, all the smartphones of the Galaxy series are categorized in the following way:

Primary

Secondary

The model number of Samsung Galaxy devices will indicate the variant:

Gear

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation.

The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.

When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.

Galaxy

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few thousand (10³) stars to giants with one hundred trillion (10¹⁴) stars, each orbiting their galaxy's own center of mass. Galaxies, are categorized according to their visual morphology, including elliptical,spiral, and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of July 2015, EGSY8p7 is the oldest and most distant observed galaxy with a light travel distance of 13.2 billion light-years from Earth, and observed as it existed 570 million years after the Big Bang. Previously, as of May 2015, EGS-zs8-1 was the most distant known galaxy, estimated to have a light travel distance of 13.1 billion light-years away and to have 15% of the mass of the Milky Way.
