Computer presentation system and method with optical tracking of wireless pointer

A computer presentation system for generating commands to remotely control a computer based on a plurality of user selectable properties of an optical cursor generated by a hand-held pointer and projected on a screen displaying output from the computer, the system comprising:

• a camera for capturing an image of the output from the computer;
• and
• a processor in communication with the camera for processing the image to detect position of the optical cursor and at least one property of the optical cursor and for converting the position and at least one property to corresponding commands to control the computer and move an internal cursor to a position corresponding to the optical cursor while the optical cursor remains within the output displayed on the screen.

A computer readable storage medium having stored data representing instructions executable by a computer to generate commands to control a cursor generated by the computer based on a plurality of user controllable properties of an external cursor, the computer readable storage medium comprising:

• instructions for detecting at least one of the user selectable properties of the external cursor;
• and
• instructions for generating a command for the computer based on the at least one detected property of the external cursor.

A computer readable storage medium having stored data representing instructions executable by a computer to generate commands to control the computer based on an external cursor projected onto an image of output generated by the computer, the computer readable storage medium comprising:

• instructions for processing an image of the output to detect at least one property of the external cursor including position of the external cursor relative to the output;
• and
• instructions for converting the position and the at least one property to a command to control the computer to move an internal cursor to a position corresponding to the external cursor.
