An aiming device (or method) which monitors rotational and angular displacement changes with high precision. The detected changes in rotation and/or angular displacement are then used in various operations depending on the implementation. The invention is useful for many different implementations, including a pointing device, a remote control device, and a shooting practice system. Regardless of implementation, the invention utilizes one or more emitters which emit modulated energy signals, and a detector which detects the emitted energy signals. The detected energy signals are processed by a processing unit to determine a point of aim (angular displacement) and a rotation of a detector with respect to the one or more emitters. As a remote control device, the invention enables a user to invoke actions by pointing and rotation of the remote control device. As a shooting practice system, the invention predicts shot placement on a target with high accuracy, while supporting both "live" fire and "dry" fire.
