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 (P) 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 (P) relative to the first and second spatial boundaries , wherein time-controlled fading includes: if the touchless control pointer (P) 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 (P) 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 (P) 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, and/or if the touchless control pointer (P) 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. 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 (P) 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 (P) relative to the first and second spatial boundaries , if the touchless control pointer (P) 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 (P) 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 (P) 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, and/or if the touchless control pointer (P) 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. <EOS>
