1. A pointing apparatus, comprising:

  • A ring-like device that is put on the finger segments equipped with inertial sensors, such as rate gyros and accelerometers, to detect the user'"'"'s hand and finger motion in the 2- and 3-dimensional spaces to manipulate or control a computer cursor or computer generated objects and such objects that are displayed on a computer display or such physical or virtual objects that are controlled by a computer or electronic control system or detect movements related to drawing different characters like those of handwriting, on a real surface or on a fictitious surface in the air Wherein the computer can be any device capable of performing computational operations at the level of complexity needed to process the flow of data generated by such a ring. Wherein the said inertial sensors provide the information about the linear and/or angular acceleration of the carrying hand/finger, so that the acceleration information can be integrated over time to achieve speed and integrated over time again to achieve momentary position of the hand/finger equipped with buttons on the periphery of the ring, such that the buttons can be pressed by the thumb or other fingers of the same hand. Wherein a button can be any mechanism or circuitry that can signal a depression or contact on the body of the ring, e.g. an electromechanical switch or a touch sensor.
