Multi-touch technology is an advanced human-computer interaction technique that recognizes multiple touch points and also includes the hardware devices that implement it, which allow users to compute without conventional input devices.

Multi-touch consists of a touch screen (screen, table, wall, etc.) or touchpad, as well as software that recognize multiple simultaneous touch points, as opposed to the standard touchscreen which recognizes only one touch point at a time. Multi touch using rear diffused illumination multi-touch technique.

Different applications for multi-touch interfaces both exist and are being proposed. Some uses are individualistic e.g. iPhone, iPod touch, MacBook Pro, MacBook Air. The use of multi-touch technology is expected to rapidly become common place.
