Enable support for the navigation gesture, in the depth axis.
This represents the user holding down their finger and moving their hand or a controller within a normalized cube with coordinates from -1.0 to 1.0. These are normalized values and do not represent any physical unit, such as meters. This gesture can be used to navigate UI widgets, such as radial menus. This can also be used to build velocity-based continuous scrolling or zooming gestures, similar to scrolling a 2D UI by clicking the middle mouse button and then moving the mouse up and down.
