It can be controlled using a remote, a game controller, or a keyboard. This difference in distance from the display has a huge impact on the interface design, requiring the use of extra large fonts on a television and allowing relatively few items to be shown on a television at once. A 10 foot UI is almost always designed to be operated by a simple hand-held remote control. This means that a designing the user interface pdf-foot UI needs to arrange items on screen in a way that clearly shows which item would be next in each of the four directions of the directional pad – usually a grid layout.
Also, without a mouse cursor, the currently-selected item must be highlighted in some way. Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Why is the “10 foot” home TV experience so hard to get right?

User can manipulate and control the software as well as hardware by means of user interface.
Today, user interface is found at almost every place where digital technology exists, right from computers, mobile phones, cars, music players, airplanes, ships etc. User interface is part of software and is designed such a way that it is expected to provide the user insight of the software. UI provides fundamental platform for human-computer interaction. UI can be graphical, text-based, audio-video based, depending upon the underlying hardware and software combination. UI can be hardware or software or a combination of both. CLI has been a great tool of interaction with computers until the video display monitors came into existence. CLI is first choice of many technical users and programmers.
CLI is minimum interface a software can provide to its users. CLI provides a command prompt, the place where the user types the command and feeds to the system. The user needs to remember the syntax of command and its use. Earlier CLI were not programmed to handle the user errors effectively. A command is a text-based reference to set of instructions, which are expected to be executed by the system. There are methods like macros, scripts that make it easy for the user to operate. CLI uses less amount of computer resource as compared to GUI.
It is text-based notifier that is mostly shows the context in which the user is working. It is generated by the software system. It is a small horizontal line or a vertical bar of the height of line, to represent position of character while typing. Cursor is mostly found in blinking state. It moves as the user writes or deletes something. A command is an executable instruction.
