A hand held control device comprising:
- a rigid body adapted for being gripped and carried by a single hand of a user while leaving the thumb and finger tips of said gripping and carrying hand free to operate control elements mounted in said rigid body;
- a plurality of control elements mounted in the rigid body for activation by a thumb or finger tip of said gripping and carrying hand to generate control data;
- transmission means located in the rigid body for communicating said control data between the hand held control device and a remotely located computing system having a display;
- at least one of said control elements being a pointing stick for controlling in a joystick-like manner actions at said display;
- at least one of said control elements corresponding to a left gripping and carrying hand-and being mounted on the rigid body for activation only by a finger tip of said gripping and carrying hand when said gripping and carrying hand is a left hand and at least one other one of said control elements corresponding to a right gripping and carrying hand and being mounted on the rigid body for activation only by a finger tip of said gripping and carrying hand when said gripping and carrying hand is a right hand:
- and
