An apparatus for use in helping to track a pointing device is disclosed herein. An example of the apparatus includes an orientation member coupled to the pointing device that includes a plurality of points at least some of which define a plane. The apparatus also includes a sensor to detect the plurality of points of the orientation member and a processor to determine a location in a workspace of each of the points of the orientation member detected by the sensor. The processor also determines a geometric property of the plane defined by at least some of the points of the orientation member and locates a position of an end of the pointing device along a line segment associated with the geometric property. A method for use in helping to track a pointing device in a workspace and a non-volatile storage medium are also disclosed herein.
