[2][3] In the past, these types of human interaction design (HID) interfaces were driven by remote controllers primarily using infrared (IR) codes signals, which are increasingly replaced by other two-way radio-frequency protocol standards such as Bluetooth while maintaining the use of IR for certain wake-up situations.
[1] This is why, when designing an interface for the TV set, it’s important to position oneself at various distances to see what different parts of the population will actually see.
Rather than the mouse or touchscreen which are commonly used with other types of user interfaces, the remote's directional pad is the primary means of navigation.
[citation needed] Ten-foot interfaces may resemble other post-WIMP systems graphically, but do not assume the use of a touch screen.
Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself.
