A system is provided herein, comprising a gaze tracking device arranged to detect a direction of a user's gaze; a three dimensional (3D) imaging device arranged to identify a user's pointing finger and a corresponding finger pointing direction; and a processor arranged to compare the detected gaze direction and the identified pointing direction and indicate an alignment therebetween. The system provides a natural user interface which may be used to interact with virtual or actual objects as well as facilitate interaction between communicating users. |
