Patent ID: 8830189

Claim:
A method for monitoring behavior of at least a part of a physical object with respect to a sensing surface so as to target and activate a virtual object on a remote screen, the method comprising: (a) providing measured data indicative of a behavior of at least a part of a physical object with respect to a predetermined sensing surface, said measured data being indicative of said behavior in a first three-dimensional space; (b) processing said measured data indicative of the behavior of said at least part of the physical object in said first three-dimensional space with respect to the sensing surface and transforming said measured data into an approximate representation of said behavior in a virtual coordinate system, the transformation maintaining a three-dimensional positional relationship between virtual points in said virtual coordinate system and corresponding portions of the physical object in said first three-dimensional space, the approximate representation including a representation of the distance from the corresponding portions of the physical objects to the sensing surface, said representation of the distance being indicative of a hovering height between said at least part of the physical object and said sensing surface; and (c) displaying on the remote screen said approximate representation of the behavior of said at least part of the physical object, wherein the virtual object is targeted in hover on the remote screen, while being activated by touch of said sensing surface.
