Technology for stabilizing an interaction ray based on variance in head rotation is disclosed. One aspect includes monitoring orientation of a person's head, which may include monitoring rotation about an axis of the head, such as recording an Euler angle with respect to rotation about an axis of the head. The logic determines a three-dimensional (3D) ray based on the orientation of the head. The 3D ray has a motion that precisely tracks the Euler angle over time. The logic generates an interaction ray that tracks the 3D ray to some extent. The logic determines a variance of the Euler angle over time. The logic stabilizes the interaction ray based on the variance of the Euler angle over time despite some rotation about the axis of the head. The amount of stabilizing may be inversely proportional to the variance of the Euler angle. |
