1. A user interaction arrangement comprising:
- a detector for detecting a three-dimensional position of a pointing object, the three-dimensional position being defined along x, y and z axes in a Cartesian coordinate system, wherein the x and y axes are along a surface of a display substantially under the position of the pointing object and the z axis is perpendicular to the xy-plane;
an image generating part for generating an image on the surface of the display substantially under the position of the pointing object; and
a controller for computing a distance of the pointing object to the surface of the display based on a position of the pointing object along the z-axis and for computing a center point of the detected pointing object based on a position of the pointing object within the xy-plane, the controller being further configured to provide the image generating part with instructions to generate a dynamic guiding image having a center at the center point of the detected pointing object, said dynamic guiding image having a progressively variable characteristic that progressively varies over a detection range of the detector depending on the distance of the pointing object to the surface of the display, and said dynamic guiding image having an appearance deviating from the image generated on the surface of the display.

Abstract
The invention relates to a user interaction arrangement for interaction with a user using a pointing object. The arrangement comprises: a detector for detecting position of said object, a controller for computing a distance of said object to a surface of a display, and an image generating part for generating an image on said surface of display. The controller is further configured to compute a position on said surface based on said position and distance of said object, and the arrangement further comprises an image generating part configured to generate a dynamic guiding image on said surface of display based on said position and distance.
