Method for utilization of a gyroscopic or inertial device as a user interface mechanism for headmounted displays and body worn computers

A method of manipulating a cursor and activating computer functions, comprising the steps of:

• providing a computer and a computer screen associated therewith;
• providing a gyroscopic sensor for mounting to the body of the user, said sensor being reactive to body movements;
• providing a mouse driver in associate with said gyroscope, such that movements of said gyroscope cause a concomitant movement of a cursor on said computer screen;
• providing a microphone;
• providing voice recognition software, associated with said microphone, said voice recognition software having a driver for activating computer functions;
• providing hierarchal commands in said voice recognition software such that selection of computer functions arc associated with simple words;
• and
• causing the movement of said cursor by moving the body part associated with said gyroscope, in a predetermined manner, and causing the execution of computer functions by selecting an icon or menu item on said screen and reciting predetermined words associated with the desired actions.
