Claim Text:
1. A method, comprising: acquiring position data about a portion of an object located at least partially in a three-dimensional hover space produced by a portable apparatus having a hover-sensitive interface, where the position data is acquired solely by a passive capacitive sensing node that detects a capacitance change in the hover space caused by the object; where the position data describes the position of the object in the three-dimensional hover space, where a first dimension and a second dimension in the hover space define a plane that is parallel to the surface of the interface, where the second dimension is orthogonal to the first dimension, and where a third dimension in the hover space is orthogonal to both the first dimension and the second dimension and perpendicular to the plane; computing an angle at which the object is pitched with respect to the hover-sensitive interface based, at least in part, on the position data; and controlling the hover-sensitive interface based, at least in part, on the angle at which the object is pitched with respect to the hover-sensitive interface.
