Concept
10-foot user interface
Summary
In computing, 10-foot user interface, 10-foot UI or 3-meter user interface is a graphical user interface designed for televisions. Compared to desktop computer and smartphone user interfaces, it uses text and other interface elements which are much larger in order to accommodate a typical television viewing distance of . Additionally, the limitations of a television's remote control necessitate extra user experience considerations to minimize user effort.
In the past, these types of human interaction design (HID) interfaces are 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. The voice interfaces are also now purposed to provide a near-field experience in addition to the far-field experience of the likes of smart speakers. One of the requirements of voice-input 10-foot user interface usually require a device like smart speaker, over-the-top (OTT) TV box or smart television with Internet connectivity supported by an advanced software operating system.
The term "10-foot" or "3-meter" is used to differentiate this user interface style from those used on desktop computers, which typically assume the user's eyes are only about two feet (24 inches, 60 cm) from the display. 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. 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. This means that a 10-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.
