input question: Information:  - The user interface (UI), in the industrial design field of humancomputer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.  - Tom Clancy's Splinter Cell is a series of award-winning stealth video games, the first of which was released in 2002, and their tie-in novels. The protagonist, Sam Fisher, is a highly trained agent of a fictional black-ops sub-division within the NSA, dubbed "Third Echelon". The player controls Fisher to overcome his adversaries in levels (created using Unreal Engine) that were extended to emphasise light and darkness as gameplay elements. All the console and PC games in the series were critically acclaimed, and the series is commercially successful. The series, along with "Assassin's Creed", is considered to be one of Ubisoft's flagship franchises, selling more than 31 million copies as of 2011.  - A computer monitor or a computer display is an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT). It can be connected to the computer via VGA, DVI, HDMI, DisplayPort, Thunderbolt, LVDS (Low-voltage differential signaling) or other proprietary connectors and signals.  - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial.  - Ubisoft Entertainment SA (formerly Ubi Soft Entertainment Software until 2003, commonly referred to as Ubisoft) is a French multinational video game publisher, headquartered in Rennes, France. It is known for developing games for several acclaimed video game franchises including "Assassin's Creed", "Far Cry", "Tom Clancy's Ghost Recon", "Just Dance", "Rainbow Six", "Prince of Persia", "Rayman", "Watch Dogs" and "Tom Clancy's Splinter Cell".  - Surf 's Up is the video game based on the Sony Pictures Animation film of the same name .

In "", it is shown that the Ghost's unit has multiple designations and is part of JSOC and is also known as the Group for Specialized Tactics (or GSTwhere the term "Ghost" comes from) much like real JSOC units like Delta Force (1st SFOD-D or CAG) and SEAL Team Six (or DEVGRU).
