1. A handheld controller operable in a one hand mode of operation and a two hand mode of operation, said controller for use in wirelessly communicating with an electronic game machine having an associated display screen, a first light emitting marker and second light emitting marker each mounted spaced from, but in the vicinity of, the display screen, said handheld controller comprising:

  • an elongated housing having an upper surface, a lower surface, a forward end, a rearward end and a longitudinal axis defining at least one longitudinal center line, and sized to be operable by one hand of a user;

    a first set of game controls proximate said forward end of said housing;

    a second set of game controls proximate said rearward end of said housing;

    said first set of game controls and said second set of game controls being operable in use in a two hand game playing mode of operation, wherein during said two hand game playing mode said first set of game controls are disposed so as to be actuated by one thumb of a user and said second set of game controls are disposed so as to be actuated by the other thumb of the user, and wherein said first and second sets of game controls are actuated in use by the cooperative action of the user'"'"'s thumbs;

    the lower surface of said housing having a concave portion provided with a trigger switch;

    a processor enclosed within said housing;

    an imaging device located in said forward end of said housing at least substantially aligned with said longitudinal center line and including a filter, a lens, an image sensor and an image processing circuit, wherein the image sensor, in use, detects light from the first light emitting marker and the second light emitting marker and generates image data, and wherein the image processing circuit, in use, receives and processes said image data and generates position data related to positional coordinates of the first light emitting marker and the second light emitting marker, and wherein the image processing circuit outputs the position data to said processor;

    at least said trigger switch and said imaging device being used in a one hand game playing mode of operation, wherein game play is controlled by the user holding the controller in one hand;

    linear accelerometer circuitry for detecting acceleration of the controller along each of three axes and for generating acceleration data along each of said three axes, said linear accelerometer circuitry being, in use, in communication with said processor; and

    a wireless communication device disposed within said housing and operatively connected to said processor and operable, in use, to transmit signals to said electronic game machine representing operational states of at least said first set of operational controls, said second set of operational controls, said trigger switch, said position data, and said acceleration data.
