1. A computer-implemented touchless user-interface control method for an electronic display, comprising:
defining a first spatial input area associated with a first depth camera for the recognition of touchless input, the first spatial input area having a first spatial boundary;
defining a second spatial input area associated with a second depth camera for the recognition of touchless input, the second spatial input area having a second spatial boundary;
detecting, using the first and the second depth camera, an input object and determining a set of 3D-points corresponding to the input object;
wherein the set of 3D-points includes a first subset of 3D-points which is based on data captured by the first depth camera, and a second subset of 3D-points which is based on data captured by the second depth camera;
determining a touchless control pointer based on the positions of the 3D-points;
performing time-controlled fading wherein one or both of the subsets of 3D-points is faded out or faded in within a period of time depending on successive positions of the touchless control pointer relative to the first and second spatial boundaries,
wherein time-controlled fading includes at least one of:
if the touchless control pointer moves from inside to outside the first spatial input area crossing the first spatial boundary, the first subset of 3D-points is faded out within a period of time, and/or
if the touchless control pointer moves from inside to outside the second spatial input area crossing the second spatial boundary, the second subset of 3D-points is faded out within a period of time, and/or
if the touchless control pointer moves from outside to inside the first spatial input area crossing the first spatial boundary, the first subset of 3D-points is faded in within a period of time, or and/or
if the touchless control pointer moves from outside to inside the second spatial input area crossing the second spatial boundary, the second subset of 3D-points is faded in within a period of time.
